Adjust the numberOfProxies logic in app.js if needed - Update the session cookie configs with sameSite attribute, domain, and path - Add Terms of Service and Privacy Policy - Update `LICENSE.md` and the relevant license field in package.json if applicable - See [npm's doc](https://docs.npmjs.com/files/package.json#license). - Add [sitemap.xml](https://en.wikipedia.org/wiki/Sitemaps) and [robots.txt](https://moz.com/learn/seo/robotstxt) - Update Google Analytics ID - Add Facebook App/Pixel ID - Add Winston Logging, and replace console.log statements with Winston; have a process for monitoring errors to identify bugs or other issues after launch. - SEO and Social Media Improvements - Create a deployment pipeline with a pre-prod/integration test stage. - (optional) Add email verification _Some experimental data has shown that bogus email addresses are not a significant problem in many cases_ - (optional) Add a filter with [disposable-email-domains](https://www.npmjs.com/package/disposable-email-domains). _Some experimental data has shown that use of disposable emails is typically rare, and in many cases it might not be worth adding the filter._ ### Remove unused code and configs The following is a list of various code that you may not potentially be using and you could remove depending on your application: - Unused keys from .env file - /controllers/api.js entirely - /views/api entirely - app.js: - multer - apiController - Openshift env references - csrf check exception for /api/upload - All API example routes - OAuth routes for authentications that you are not using (i.e. GitHub, LinkedIn, etc. based on your app) - All OAuth authorization routes - passport.js all references and functions related to: - Github, LinkedIn, OpenID, OAuth, OAuth2 - model/User.js - key pairs for Github, LinkedIn, Steam - package.json - @octokit/rest, lastfm, lob, multer, node-linkedin, passport-github2, passport-linkedin-oauth2, passport-oauth, paypal-rest-sdk, stripe, twilio - /test - Replace E2E and API example tests with new tests for your application - views/account/login.pug - Some or all of the last form-group set, which are the social login choices - views/account/profile.pug - Link/unlink buttons for GitHub, LinkedIn, Steam - Remove README, changelog and this guide if not using them - Create a domain whitelist for your app in Here's developer portal if you are using the HERE Maps API. - Add unit tests so you can test and incorporate dependency and upstream updates with less effort. GPT tools may create some good unit tests with very low effort. ### Search Engine Optimization (SEO) Note that SEO only applies to the pages that will be publicly visible with no authentication. Note that some of the following fields need to be added to the HTML header section similar to the page [title](https://github.com/sahat/hackathon-starter/blob/master/views/layout.pug#L9) - Add Open Graph fields for SEO Open Graph data: ``` ``` - Add a page description, which will show up in the search results of the search engine. ``` ``` ================================================ FILE: README.md ================================================ ![](https://lh4.googleusercontent.com/-PVw-ZUM9vV8/UuWeH51os0I/AAAAAAAAD6M/0Ikg7viJftQ/w1286-h566-no/hackathon-starter-logo.jpg) Hackathon Starter ======================= **Live Demo**: [Link](https://hackathon-starter-1.ydftech.com) Jump to [What's new?](https://github.com/sahat/hackathon-starter/blob/master/CHANGELOG.md) A boilerplate for **Node.js** web applications. If you have attended any hackathons in the past, then you know how much time it takes to get a project started: decide on what to build, pick a programming language, pick a web framework, pick a CSS framework. A while later, you might have an initial project up on GitHub, and only then can other team members start contributing. Or how about doing something as simple as _Sign in with Facebook_ authentication? You can spend hours on it if you are not familiar with how OAuth 2.0 works. When I started this project, my primary focus was on **simplicity** and **ease of use**. I also tried to make it as **generic** and **reusable** as possible to cover most use cases of hackathon web apps, without being too specific. In the worst case, you can use this as a learning guide for your projects, if for example you are only interested in **Sign in with Google** authentication and nothing else. ### Testimonials > [**"Nice!

Alternatively, here is another great tutorial for complete beginners - [Getting Started With Node.js, Express, MongoDB](https://www.freecodecamp.org/news/build-a-restful-api-using-node-express-and-mongodb/). ## Getting Started **Step 1:** The easiest way to get started is to clone the repository: ```bash # Get the latest snapshot git clone https://github.com/sahat/hackathon-starter.git myproject # Change directory cd myproject # Install NPM dependencies npm install # Then simply start your app npm start ``` **Note:** I highly recommend installing [Nodemon](https://github.com/remy/nodemon). It watches for any changes in your node.js app and automatically restarts the server. Once installed, instead of `node app.js` use `nodemon app.js`. It will save you a lot of time in the long run, because you won't need to manually restart the server each time you make a small change in code. To install, run `sudo npm install -g nodemon`. **Step 2:** Obtain API Keys and change configs if needed After completing step 1 and locally installing MongoDB, you should be able to access the application through a web browser and use local user accounts. However, certain functions like API integrations may not function correctly until you obtain specific keys from service providers. The keys provided in the project serve as placeholders, and you can retain them for features you are not currently utilizing. To incorporate the acquired keys into the application, you have two options: 1. Set environment variables in your console session: Alternatively, you can set the keys as environment variables directly through the command prompt. For instance, in bash, you can use the `export` command like this: `export FACEBOOK_SECRET=xxxxxx`. This method is considered a better practice as it reduces the risk of accidentally including your secrets in a code repository. 2. Replace the keys in the `.env.example` file: Open the `.env.example` file and update the placeholder keys with the newly acquired ones. This method has the risk of accidental checking-in of your secrets to code repos. _What to get and configure:_ - SMTP - For user workflows for reset password and verify email - For contact form processing - reCAPTCHA - For contact form submission, but you can skip it during your development - OAuth for social logins (Sign in with / Login with) - Depending on your application need, obtain keys from Google, Facebook, X (Twitter), LinkedIn, Twitch, GitHub. You don't have to obtain valid keys for any provider that you don't need. Just remove the buttons and links in the login and account pug views before your demo. - API keys for service providers that you need in the API Examples if you are planning to use them. - MongoDB Atlas - If you are using MongoDB Atlas instead of a local db, set the MONGODB_URI to your db URI (including your db user/password). - Email address - Set SITE_CONTACT_EMAIL as your incoming email address for messages sent to you through the contact form. - Set TRANSACTION_EMAIL as the "From" address for emails sent to users through the lost password or email verification emails to users. You may set this to the same address as SITE_CONTACT_EMAIL. **Step 3:** Setup an HTTPS proxy to access the app with an https address: See - [HTTPS Proxy](#https-proxy) **Step 4:** Develop your application and customize the experience - Check out [How It Works](#how-it-works-mini-guides) **Step 5:** Optional - deploy to production See: - [Deployment](#deployment) - [prod-checklist.md](https://github.com/sahat/hackathon-starter/blob/master/prod-checklist.md) ## HTTPS Proxy: If you want to use an API that requires HTTPS (for example, GitHub or Facebook), you need to run the app with an HTTPS URL. You can do this by setting up an HTTPS proxy using either ngrok or Cloudflare. Note: When using an HTTPS proxy, you may get a CSRF mismatch error if you try to directly access the app at `http://localhost:8080` instead of the HTTPS proxy address. ### ngrok - Download [ngrok](https://ngrok.com/download). - Start ngrok. - Set your BASE_URL to the forwarding address from ngrok (i.e., `https://3ccb-1234-abcd.ngrok-free.app`). This will be the HTTPS address for accessing the app. ### Cloudflare - Download and install [cloudflared](https://developers.cloudflare.com/cloudflare-one/networks/connectors/cloudflare-tunnel/downloads). - For a quick, free tunnel with a random subdomain under `trycloudflare.com`, execute: ``` cloudflared tunnel --url http://localhost:8080 ``` - Set BASE_URL to the HTTPS address for the tunnel. #### Cloudflare with your own domain name If you own a domain managed by Cloudflare, you can use Cloudflare's Zero Trust portal to set up a tunnel to your app that is activated by a system service. Alternatively, you can create a tunnel and route a subdomain you like to your app using their CLI: ``` cloudflared tunnel login cloudflared tunnel create myapptunnel cloudflared tunnel route dns myapptunnel myappsubdomain.mydomain.com cloudflared tunnel --url http://localhost:8080 run myapptunnel ``` Then set BASE_URL to the HTTPS address for the tunnel. Note that the tunnel and DNS route are a one-time setup. To reactivate the HTTPS tunnel to your app later, such as after a system restart, just rerun: ``` cloudflared tunnel --url http://localhost:8080 run myapptunnel ``` To clean up your own domain's related configurations when you're done: - Delete the tunnel by executing `cloudflared tunnel delete myapptunnel` - Remove the `myappsubdomain` DNS entry from your domain through the Cloudflare web UI. - Remove `%USERPROFILE%\.cloudflared` (Windows) or `~/.cloudflared` (Linux/macOS) if you want to clear local credentials. # Obtaining API Keys You will need to obtain appropriate credentials (Client ID, Client Secret, API Key, or Username & Password) for API and service providers which you need. See Step 2 in the Getting started section for more info. ## SMTP Obtain SMTP credentials from a provider for transactional emails. Set the SMTP_USER, SMTP_PASSWORD, and SMTP_HOST environment variables accordingly. When picking the SMTP host, keep in mind that the app is configured to use secure SMTP transmissions over port 465 out of the box. You have the flexibility to select any provider that suits your needs or take advantage of one of the following providers, each offering a free tier for your convenience. | Provider | Free Tier | Website | | -------- | -------------------------- | ----------------------- | | SMTP2Go | 1000 emails/month for free | https://www.smtp2go.com | | Brevo | 300 emails/day for free | https://www.brevo.com |

Many of these tools are available for free and offer features that can significantly enhance your coding experience. You have two main options for accessing these tools: - **Web-based chat interfaces**: Platforms like [ChatGPT](https://chat.openai.com/) and [MS Copilot](https://copilot.microsoft.com/) - **Integrated code assistants**: Tools like [Amazon Q (CodeWhisperer)](https://aws.amazon.com/q/developer/pricing/), [GitHub Copilot](https://github.com/features/copilot), and Gemini Code Assist integrate directly into code editors, such as Visual Studio Code. Integrated tools, like plugins for Visual Studio Code, let you reference your code directly without needing to copy-paste, making them easier to use in many cases. Web-based assistants, on the other hand, require manual copy-pasting but can offer a different approach without impacting the "context" for your integrated tool. Tools and models perform differently depending on their update cycles, so results may vary. If an integrated tool struggles with a task, try copy-pasting the relevant code into a web assistant to troubleshoot. A good starting point is combining Amazon Q and MS Copilot, as these tools tend to produce fewer issues like outdated syntax, vulnerable code, or incomplete solutions compared to other assistants. ### Providing Context to AI Tools Context for LLMs is the additional information that the model needs to make sense of how it should respond to your question, which in coding is probably your existing code, example implementation, or specifications that you might copy-paste or pass to the model. Keep in mind that integrated assistants may not automatically include your project files as the context and may try to answer your question without looking at your code. To include the context: - **Amazon Q**: Use `@[filename]` to specify a file or `@workspace` to include the entire project. - **GitHub Copilot**: Click the "Add Context" button in the chat and manually add specific files or choose Codebase for full project context. Note that you need to set the copilot mode to "Ask", "Edit", etc based on your intended conversation. ### Example Prompts to Get You Started **Explaining Code and Concepts** - "Can you explain how this project handles sanitization of user inputs?" - "What does function `x` in file `y` do?" (_Copy-paste code into a web-based assistant if using one._) - "Can you walk me through what this regex does?" **Adding New Features** - "I want to add login functionality for [OAuth2 provider]. The project already includes similar logins for other providers. Can you guide me through the required changes to `app.js`, `config/passport.js`, `models/User.js`, and the relevant views?" _Pro Tip:_ If the assistant misses some changes, follow up with specific files or provide relevant documentation for better accuracy. - "Can you help me design an addition to this project to do the following. I don't need any code yet, and want to work on the design and refine it before moving to an implementation. --- continue with a bullet point list of your requirements" **Debugging or Fixing Code** - "I modified the function `x` below to achieve `y`, but I get the following error. Can you help me fix it? --- Can have blocks afterward with a header like `==== error ====` and `==== function x ====` afterward." - "Can you help me fix a bug in the following function or function `x`. It is supposed to return `y` when it gets input `i` but it is returning `z`." - "Can you check my comments for spelling issues?". ## FAQ ### Why do I get `403 Error: Forbidden` when submitting a form? You need to add the following hidden input element to your form. This has been added in the [pull request #40](https://github.com/sahat/hackathon-starter/pull/40) as part of the CSRF protection. ``` input(type='hidden', name='_csrf', value=_csrf) ``` **Note:** It is now possible to whitelist certain URLs. In other words, you can specify a list of routes that should bypass the CSRF verification check. **Note 2:** To whitelist dynamic URLs use regular expression tests inside the CSRF middleware to see if `req.originalUrl` matches your desired pattern. ### I am getting MongoDB Connection Error, how do I fix it? That's a custom error message defined in `app.js` to indicate that there was a problem connecting to MongoDB: ```js mongoose.connection.on('error', (err) => { console.error(err); console.log('%s MongoDB connection error. Please make sure MongoDB is running.'); process.exit(1); }); ``` You need to have a MongoDB server running before launching `app.js`. You can download MongoDB [here](https://www.mongodb.com/try/download/community), or install it via a package manager. Windows users, read [Install MongoDB on Windows](https://www.mongodb.com/docs/manual/tutorial/install-mongodb-on-windows//). **Tip:** If you are always connected to the internet, you could just use [MongoDB Atlas](https://www.mongodb.com) instead of downloading and installing MongoDB locally. You will only need to update the database credentials in the `.env` file. **NOTE:** MongoDB Atlas (cloud database) is required for vector store, index, and search features used in AI integrations. These features are NOT available in locally installed MongoDBs. ### I get an error when I deploy my app, why? Chances are you haven't changed the _Database URI_ in `.env`. If `MONGODB` is set to `localhost`, it will only work on your machine as long as MongoDB is running. When you deploy to Render, OpenShift, or some other provider, you will not have MongoDB running on `localhost`. You need to create an account with [MongoDB Atlas](https://www.mongodb.com), then create a free tier database. See [Deployment](#deployment) for more information on how to set up an account and a new database step-by-step with MongoDB Atlas. ### Why do you have all routes defined in app.js? For the sake of simplicity. While there might be a better approach, such as passing `app` context to each controller as outlined in this [blog](http://timstermatic.github.io/blog/2013/08/17/a-simple-mvc-framework-with-node-and-express/), I find such a style to be confusing for beginners. It took me a long time to grasp the concept of `exports` and `module.exports`, let alone having a global `app` reference in other files. That to me is backward thinking. The `app.js` is the "heart of the app", it should be the one referencing models, routes, controllers, etc. When working solo on small projects, I prefer to have everything inside `app.js` as is the case with [this](<(https://github.com/sahat/ember-sass-express-starter/blob/master/app.js)>) REST API server. ## How It Works (mini guides) This section is intended for giving you a detailed explanation of how a particular functionality works. Maybe you are just curious about how it works, or perhaps you are lost and confused while reading the code, I hope it provides some guidance to you. ### Custom HTML and CSS Design 101 [HTML5 UP](http://html5up.net/) has many beautiful templates that you can download for free. When you download the ZIP file, it will come with _index.html_, _images_, _CSS_ and _js_ folders. So, how do you integrate it with Hackathon Starter? Hackathon Starter uses the Bootstrap CSS framework, but these templates do not. Trying to use both CSS files at the same time will likely result in undesired effects. **Note:** Using the custom templates approach, you should understand that you cannot reuse any of the views I have created: layout, the home page, API browser, login, signup, account management, contact. Those views were built using Bootstrap grid and styles. You will have to manually update the grid using a different syntax provided in the template. **Having said that, you can mix and match if you want to do so: Use Bootstrap for the main app interface, and a custom template for a landing page.** Let's start from the beginning. For this example I will use [Escape Velocity](http://html5up.net/escape-velocity/) template: ![Alt](http://html5up.net/uploads/images/escape-velocity.jpg) **Note:** For the sake of simplicity I will only consider `index.html`, and skip `left-sidebar.html`, `no-sidebar.html`, `right-sidebar.html`. Move all JavaScript files from `html5up-escape-velocity/js` to `public/js`. Then move all CSS files from `html5up-escape-velocity/css` to `public/css`. And finally, move all images from `html5up-escape-velocity/images` to `public/images`. You could move it to the existing **img** folder, but that would require manually changing every `img` reference. Grab the contents of `index.html` and paste it into [HTML To Pug](https://html-to-pug.com/). **Note:** Do not forget to update all the CSS and JS paths accordingly. Create a new file `escape-velocity.pug` and paste the Pug markup in `views` folder. Whenever you see the code `res.render('account/login')` - that means it will search for `views/account/login.pug` file. Let's see how it looks. Create a new controller **escapeVelocity** inside `controllers/home.js`: ```js exports.escapeVelocity = (req, res) => { res.render('escape-velocity', { title: 'Landing Page', }); }; ``` And then create a route in `app.js`. I placed it right after the index controller: ```js app.get('/escape-velocity', homeController.escapeVelocity); ``` Restart the server (if you are not using **nodemon**); then you should see the new template at `http://localhost:8080/escape-velocity` I will stop right here, but if you would like to use this template as more than just a single page, take a look at how these Pug templates work: `layout.pug` - base template, `index.pug` - home page, `partials/header.pug` - Bootstrap navbar, `partials/footer.pug` - sticky footer. You will have to manually break it apart into smaller pieces. Figure out which part of the template you want to keep the same on all pages - that's your new `layout.pug`. Then, each page that changes, be it `index.pug`, `about.pug`, `contact.pug` will be embedded in your new `layout.pug` via `block content`. Use existing templates as a reference. This is a rather lengthy process, and templates you get from elsewhere might have yet another grid system. That's why I chose _Bootstrap_ for the Hackathon Starter. Many people are already familiar with _Bootstrap_, plus it's easy to get started with it if you have never used _Bootstrap_. You can also buy many beautifully designed _Bootstrap_ themes at various vendors, and use them as a drop-in replacement for Hackathon Starter, just make sure they support the latest version of Bootstrap. However, if you would like to go with a completely custom HTML/CSS design, this should help you to get started!
### How do flash messages work in this project? Flash messages allow you to display a message at the end of the request and access it on the next request and only the next request. For instance, on a failed login attempt, you would display an alert with some error message, but as soon as you refresh that page or visit a different page and come back to the login page, that error message will be gone. It is only displayed once. This project uses a middleware for displaying flash messages. You don't have to explicitly send a flash message to every view inside `res.render()`. All flash messages are available in your views via `messages` object by default. Flash messages have a two-step process. You use `req.flash('errors', { msg: 'Error messages goes here' }` to create a flash message in your controllers, and then display them in your views: ```pug if messages.errors .alert.alert-danger.fade.in each error in messages.errors div= error.msg ``` In the first step, `'errors'` is the name of a flash message, which should match the name of the property on `messages` object in your views. You place alert messages inside `if message.errors` because you don't want to show them flash messages are present. The reason why you pass an error like `{ msg: 'Error message goes here' }` instead of just a string - `'Error message goes here'`, is for the sake of consistency. To clarify that, _express-validator_ module which is used for validating and sanitizing user's input, returns all errors as an array of objects, where each object has a `msg` property with a message why an error has occurred. Here is a more general example of what express-validator returns when there are errors present: ```js [ { param: 'name', msg: 'Name is required', value: '' }, { param: 'email', msg: 'A valid email is required', value: '' }, ]; ``` To keep consistent with that style, you should pass all flash messages as `{ msg: 'My flash message' }` instead of a string. Otherwise, you will see an alert box without an error message. That is because in **partials/flash.pug** template it will try to output `error.msg` (i.e. `"My flash message".msg`), in other words, it will try to call a `msg` method on a _String_ object, which will return _undefined_. Everything I just mentioned about errors, also applies to "info" and "success" flash messages, and you could even create a new one yourself, such as: **Data Usage Controller (Example)** ``` req.flash('warning', { msg: 'You have exceeded 90% of your data usage' }); ``` **User Account Page (Example)** ```pug if messages.warning .alert.alert-warning.fade.in each warning in messages.warning div= warning.msg ``` `partials/flash.pug` is a partial template that contains how flash messages are formatted. Previously, flash messages were scattered throughout each view that used flash messages (contact, login, signup, profile), but now, thankfully it uses a _DRY_ approach. The flash messages partial template is _included_ in the `layout.pug`, along with footer and navigation. ```pug body include partials/header .container include partials/flash block content include partials/footer ``` If you have any further questions about flash messages, please feel free to open an issue, and I will update this mini-guide accordingly, or send a pull request if you would like to include something that I missed.
### How do I create a new page? A more correct way to say this would be "How do I create a new route?" The main file `app.js` contains all the routes. Each route has a callback function associated with it. Sometimes you will see three or more arguments for a route. In a case like that, the first argument is still a URL string, while middle arguments are what's called middleware. Think of middleware as a door. If this door prevents you from continuing forward, you won't get to your callback function. One such example is a route that requires authentication. ```js app.get('/account', passportConfig.isAuthenticated, userController.getAccount); ``` It always goes from left to right. A user visits `/account` page. Then `isAuthenticated` middleware checks if you are authenticated: ```js exports.isAuthenticated = (req, res, next) => { if (req.isAuthenticated()) { return next(); } res.redirect('/login'); }; ``` If you are authenticated, you let this visitor pass through your "door" by calling `return next();`. It then proceeds to the next middleware until it reaches the last argument, which is a callback function that typically renders a template on `GET` requests or redirects on `POST` requests. In this case, if you are authenticated, you will be redirected to the _Account Management_ page; otherwise, you will be redirected to the _Login_ page. ```js exports.getAccount = (req, res) => { res.render('account/profile', { title: 'Account Management', }); }; ``` Express.js has `app.get`, `app.post`, `app.put`, `app.delete`, but for the most part, you will only use the first two HTTP verbs, unless you are building a RESTful API. If you just want to display a page, then use `GET`, if you are submitting a form, sending a file then use `POST`. Here is a typical workflow for adding new routes to your application. Let's say we are building a page that lists all books from the database. **Step 1.** Start by defining a route. ```js app.get('/books', bookController.getBooks); ``` --- **Note:** As of Express 4.x you can define your routes like so: ```js app.route('/books').get(bookController.getBooks).post(bookController.createBooks).put(bookController.updateBooks).delete(bookController.deleteBooks); ``` And here is how a route would look if it required an _authentication_ and an _authorization_ middleware: ```js app.route('/api/twitch').all(passportConfig.isAuthenticated).all(passportConfig.isAuthorized).get(apiController.getTwitch).post(apiController.postTwitch); ``` Use whichever style makes sense to you. Either one is acceptable. I think that chaining HTTP verbs on `app.route` is a very clean and elegant approach, but on the other hand, I can no longer see all my routes at a glance when you have one route per line. **Step 2.** Create a new schema and a model `Book.js` inside the _models_ directory. ```js const mongoose = require('mongoose'); const bookSchema = new mongoose.Schema({ name: String, }); const Book = mongoose.model('Book', bookSchema); module.exports = Book; ``` **Step 3.** Create a new controller file called `book.js` inside the _controllers_ directory. ```js /** * GET /books * List all books. */ const Book = require('../models/Book.js'); exports.getBooks = (req, res) => { Book.find((err, docs) => { res.render('books', { books: docs }); }); }; ``` **Step 4.** Import that controller in `app.js`. ```js const bookController = require('./controllers/book'); ``` **Step 5.** Create `books.pug` template. ```pug extends layout block content .page-header h3 All Books ul each book in books li= book.name ``` That's it! I will say that you could have combined Step 1, 2, 3 as following: ```js app.get('/books', (req, res) => { Book.find((err, docs) => { res.render('books', { books: docs }); }); }); ``` Sure, it's simpler, but as soon as you pass 1000 lines of code in `app.js` it becomes a little challenging to navigate the file. I mean, the whole point of this boilerplate project was to separate concerns, so you could work with your teammates without running into _MERGE CONFLICTS_. Imagine you have four developers working on a single `app.js`, I promise you it won't be fun resolving merge conflicts all the time. If you are the only developer, then it's okay. But as I said, once it gets up to a certain LoC size, it becomes difficult to maintain everything in a single file. That's all there is to it. Express.js is super simple to use. Most of the time you will be dealing with other APIs to do the real work: [Mongoose](http://mongoosejs.com/docs/guide.html) for querying database, socket.io for sending and receiving messages over WebSockets, sending emails via [Nodemailer](http://nodemailer.com/), form validation using [validator.js](https://github.com/validatorjs/validator.js) library, parsing websites using [Cheerio](https://github.com/cheeriojs/cheerio), etc.
### AI Agent Controller LangChain v1 ReAct agent intended as a starting point for building new AI agents. The end-to-end implementation supports: - **Tool execution** with automatic retry middleware for transient failures - **MongoDB session persistence** - Chat history persists across page reloads (authenticated users: permanent until account deletion; unauthenticated: tied to Express session lifecycle) - **Input guardrails** - Prompt injection/jailbreak detection using a guard model (e.g., Llama Guard 4) - **Conversation summarization** - Long conversations are condensed to stay within context limits - **Real-time streaming** - Server-Sent Events (SSE) for live responses To build your Agent using this controller as a starting point, you need to do two things: #### 1. Define the agent's role Edit the `systemPrompt` in `createAIAgent()` to describe what the agent does and which tools it can use. ``` systemPrompt: `You are a helpful [... e.g. travel, personal assistant, exam grading] agent. Your responsibilities: 1. [YOUR_RESPONSIBILITY_1] 2. [YOUR_RESPONSIBILITY_2] 3. [YOUR_RESPONSIBILITY_3] Available tools: [LIST_YOUR_TOOLS_HERE]` ``` --- #### 2. Replace the tools Add tools specific to your project by replacing the existing tools in the `tools` array inside `createAIAgent()`. The existing tool functions can be removed. Tools follow this structure and use a Zod schema for input validation: ```js const myTool = tool( async ({ input }, config) => { config.writer?.({ message: 'Calling my service...' }); // Call your API or database const result = await callYourAPI(input); return JSON.stringify(result); }, { name: 'my_tool', description: 'Does something specific', schema: z.object({ input: z.string().describe('The input'), }), }, ); ``` --- #### Other Functions in ai-agent.js These functions handle streaming, parsing, and session management and typically do not need modification: - `promptGuardMiddleware()` : LangChain middleware that classifies user input before the agent processes it. Blocks unsafe prompts and redirects the conversation. - `getCheckpointer()` : Initializes the MongoDB checkpointer for session persistence. - `cleanupOrphanedTempSessions()` : Cleans up checkpoint data for unauthenticated users whose Express sessions have expired. Called on app startup. - `getAIAgent(req, res)` : Express route (GET /ai/ai-agent) - Renders the AI agent demo page and loads prior messages. - `postAIAgentChat(req, res)` : Express route (POST /ai/ai-agent/chat) - Main SSE endpoint. Streams AI responses, tool progress, and debug data. - `postAIAgentReset(req, res)` : Express route (POST /ai/ai-agent/reset) - Clears the user's chat session from MongoDB. - `deleteUserAIAgentData(userId)` : Called when a user deletes their account to clean up their chat data. - `sendSSE(res, eventType, data)` : Sends typed SSE events to the frontend. - `extractAIMessages(data)` : Extracts user-visible AI messages from agent stream updates. - `extractStatus(data)` : Derives tool call and completion status messages. #### Environment Variables The AI Agent requires these environment variables: - `GROQ_API_KEY` : Your Groq API key - `GROQ_MODEL` : The main LLM model (e.g., `llama-3.3-70b-versatile`) - `GROQ_MODEL_PROMPT_GUARD` : The guard model for input safety (e.g., `meta-llama/llama-guard-4-12b`) ### How do I use Socket.io with Hackathon Starter? [Dan Stroot](https://github.com/dstroot) submitted an excellent [pull request](https://github.com/dstroot/hackathon-starter/commit/0a632def1ce8da446709d92812423d337c977d75) that adds a real-time dashboard with socket.io. And as much as I'd like to add it to the project, I think it violates one of the main principles of the Hackathon Starter: > When I started this project, my primary focus was on simplicity and ease of use. > I also tried to make it as generic and reusable as possible to cover most use cases of > hackathon web apps, **without being too specific**. When I need to use socket.io, I **really** need it, but most of the time - I don't. But more importantly, WebSockets support is still experimental on most hosting providers. Due to past provider issues with WebSockets, I have not include socket.io as part of the Hackathon Starter. _For now..._ If you need to use socket.io in your app, please continue reading. First, you need to install socket.io: ```js npm install socket.io ``` Replace `const app = express();` with the following code: ```js const app = express(); const server = require('http').Server(app); const io = require('socket.io')(server); ``` I like to have the following code organization in `app.js` (from top to bottom): module dependencies, import controllers, import configs, connect to database, express configuration, routes, start the server, socket.io stuff. That way I always know where to look for things. Add the following code at the end of `app.js`: ```js io.on('connection', (socket) => { socket.emit('greet', { hello: 'Hey there browser!' }); socket.on('respond', (data) => { console.log(data); }); socket.on('disconnect', () => { console.log('Socket disconnected'); }); }); ``` One last thing left to change: ```js app.listen(app.get('port'), () => { ``` to ```js server.listen(app.get('port'), () => { ``` At this point, we are done with the back-end. You now have a choice - to include your JavaScript code in Pug templates or have all your client-side JavaScript in a separate file - in `app.js`. I admit, when I first started with Node.js and JavaScript in general, I placed all JavaScript code inside templates because I have access to template variables passed in from Express right then and there. It's the easiest thing you can do, but also the least efficient and harder to maintain. Since then I almost never include inline JavaScript inside templates anymore. But it's also understandable if you want to take the easier road. Most of the time you don't even care about performance during hackathons, you just want to _"get shit done"_ before the time runs out. Well, either way, use whichever approach makes more sense to you. At the end of the day, it's **what** you build that matters, not **how** you build it. If you want to stick all your JavaScript inside templates, then in `layout.pug` - your main template file, add this to the `head` block. ```pug script(src='/socket.io/socket.io.js') script. let socket = io.connect(window.location.href); socket.on('greet', function (data) { console.log(data); socket.emit('respond', { message: 'Hey there, server!' }); }); ``` **Note:** Notice the path of the `socket.io.js`, you don't actually have to have `socket.io.js` file anywhere in your project; it will be generated automatically at runtime. If you want to have JavaScript code separate from templates, move that inline script code into `app.js`, inside the `$(document).ready()` function: ```js $(document).ready(function () { // Place JavaScript code here... let socket = io.connect(window.location.href); socket.on('greet', function (data) { console.log(data); socket.emit('respond', { message: 'Hey there, server!' }); }); }); ``` And we are done! ## Cheatsheets ### ES6 Cheatsheet #### Declarations Declares a read-only named constant. ```js const name = 'yourName'; ``` Declares a block scope local variable. ```js let index = 0; ``` #### Template Strings Using the **\`${}\`** syntax, strings can embed expressions. ```js const name = 'Oggy'; const age = 3; console.log(`My cat is named ${name} and is ${age} years old.`); ``` #### Modules To import functions, objects, or primitives exported from an external module. These are the most common types of importing. ```js const name = require('module-name'); ``` ```js const { foo, bar } = require('module-name'); ``` To export functions, objects, or primitives from a given file or module. ```js module.exports = { myFunction }; ``` ```js module.exports.name = 'yourName'; ``` ```js module.exports = myFunctionOrClass; ``` #### Spread Operator The spread operator allows an expression to be expanded in places where multiple arguments (for function calls) or multiple elements (for array literals) are expected. ```js myFunction(...iterableObject); ``` ```jsx ``` #### Promises A Promise is used in asynchronous computations to represent an operation that hasn't completed yet but is expected in the future. ```js var p = new Promise(function (resolve, reject) {}); ``` The `catch()` method returns a Promise and deals with rejected cases only. ```js p.catch(function (reason) { /* handle rejection */ }); ``` The `then()` method returns a Promise. It takes two arguments: callback for the success & failure cases. ```js p.then( function (value) { /* handle fulfillment */ }, function (reason) { /* handle rejection */ }, ); ``` The `Promise.all(iterable)` method returns a promise that resolves when all of the promises in the iterable argument have resolved or rejects with the reason of the first passed promise that rejects. ```js Promise.all([p1, p2, p3]).then(function (values) { console.log(values); }); ``` #### Arrow Functions Arrow function expression. Shorter syntax & lexically binds the `this` value. Arrow functions are anonymous. ```js (singleParam) => { statements; }; ``` ```js () => { statements; }; ``` ```js (param1, param2) => expression; ``` ```js const arr = [1, 2, 3, 4, 5]; const squares = arr.map((x) => x * x); ``` #### Classes The class declaration creates a new class using prototype-based inheritance. ```js class Person { constructor(name, age, gender) { this.name = name; this.age = age; this.gender = gender; } incrementAge() { this.age++; } } ``` :gift: **Credits**: [DuckDuckGo](https://duckduckgo.com/?q=es6+cheatsheet&ia=cheatsheet&iax=1) and [@DrkSephy](https://github.com/DrkSephy/es6-cheatsheet). :top: [**back to top**](#table-of-contents) ### JavaScript Date Cheatsheet #### Unix Timestamp (seconds) ```js Math.floor(Date.now() / 1000); ``` #### Add 30 minutes to a Date object ```js var now = new Date(); now.setMinutes(now.getMinutes() + 30); ``` #### Date Formatting ```js // DD-MM-YYYY var now = new Date(); var DD = now.getDate(); var MM = now.getMonth() + 1; var YYYY = now.getFullYear(); if (DD < 10) { DD = '0' + DD; } if (MM < 10) { MM = '0' + MM; } console.log(MM + '-' + DD + '-' + YYYY); // 03-30-2016 ``` ```js // hh:mm (12 hour time with am/pm) var now = new Date(); var hours = now.getHours(); var minutes = now.getMinutes(); var amPm = hours >= 12 ? 'pm' : 'am'; hours = hours % 12; hours = hours ? hours : 12; minutes = minutes < 10 ? '0' + minutes : minutes; console.log(hours + ':' + minutes + ' ' + amPm); // 1:43 am ``` #### Next week Date object ```js var today = new Date(); var nextWeek = new Date(today.getTime() + 7 * 24 * 60 * 60 * 1000); ``` #### Yesterday Date object ```js var today = new Date(); var yesterday = date.setDate(date.getDate() - 1); ``` :top: [**back to top**](#table-of-contents) ### Mongoose Cheatsheet #### Find all users: ```js User.find((err, users) => { console.log(users); }); ``` #### Find a user by email: ```js let userEmail = 'example@gmail.com'; User.findOne({ email: { $eq: email.toLowerCase() } }).then((user) => { console.log(user); }); ``` #### Find 5 most recent user accounts: ```js User.find() .sort({ _id: -1 }) .limit(5) .exec((err, users) => { console.log(users); }); ``` #### Get the total count of a field from all documents: Let's suppose that each user has a `votes` field and you would like to count the total number of votes in your database across all users. One very inefficient way would be to loop through each document and manually accumulate the count. Or you could use [MongoDB Aggregation Framework](https://docs.mongodb.org/manual/core/aggregation-introduction/) instead: ```js User.aggregate({ $group: { _id: null, total: { $sum: '$votes' } } }, (err, votesCount) => { console.log(votesCount.total); }); ``` :top: [**back to top**](#table-of-contents) ## Deployment Using a local instance on your laptop with ngrok is a good solution for your demo during the hackathon, and you wouldn't necessarily need to deploy to a cloud platform. If you wish to have your app run 24x7 for a general audience, once you are ready to deploy your app, you will need to create an account with a cloud platform to host it. There are a number of cloud service providers out there that you can research. Service providers like AWS and Azure provide a free tier of service which can help you get started with just some minor costs (such as traffic overage if any, etc). --- ### Hosted MongoDB Atlas - Go to [mongodb.com](https://www.mongodb.com/) - Click the green **Try free** button - Fill in your information then hit **Create your Atlas account** - You will be redirected to Create New Cluster page. - Select a **Cloud Provider and Region** - Set the cluster Tier to Free Forever **Shared** Cluster - Give Cluster a name (default: Cluster0) - Click on the green **:zap:Create Cluster button** - Now, to access your database you need to create a DB user. To create a new MongoDB user, from the **Clusters view**, select the **Security tab** - Under the **MongoDB Users** tab, click on **+Add New User** - Fill in a username and password and give it either **Atlas Admin** User Privilege - Next, you will need to create an IP address whitelist and obtain the connection URI. In the Clusters view, under the cluster details (i.e. SANDBOX - Cluster0), click on the **CONNECT** button. - Under section **(1) Check the IP Whitelist**, click on **ALLOW ACCESS FROM ANYWHERE**. The form will add a field with `0.0.0.0/0`. Click **SAVE** to save the `0.0.0.0/0` whitelist. - Under section **(2) Choose a connection method**, click on **Connect Your Application** - In the new screen, select **Node.js** as Driver and version **3.6 or later**. - Finally, copy the URI connection string and replace the URI in MONGODB_URI of `.env.example` with this URI string. Make sure to replace the with the db User password that you created under the Security tab. - Note that after some of the steps in the Atlas UI, you may see a banner stating `We are deploying your changes`. You will need to wait for the deployment to finish before using the DB in your application. ## Production If you are starting with this boilerplate to build an application for prod deployment, or if after your hackathon you would like to get your project hardened for production use, see [prod-checklist.md](https://github.com/sahat/hackathon-starter/blob/master/prod-checklist.md). ## Testing Hackathon Starter includes both unit tests and end-to-end (E2E) tests. - **Unit tests** focus on core functionality, such as user account management. - **E2E tests** use [Playwright](https://playwright.dev/) to run the application in a headless Chrome browser, making live API calls and verifying rendered views. These tests are located in `test/e2e/` and `test/e2e-nokey/`. The nokey tests are tests that don't require API keys to run. During a hackathon, you typically don't need to worry about E2E tests; they can slow you down when you're focused on rapid prototyping. However, if you plan to launch your project for real-world use, adding and maintaining E2E tests is strongly recommended. They help ensure that future changes don't unintentionally break existing functionality. The existing E2E tests cover the example API integrations included in the starter project. You can use these as **examples or templates** when creating your own test files, adapting them to match your project's specific views and workflows. You can run the tests using: ```bash npm test # unit tests (core functions) npm run test:e2e:live # All E2E tests with previously recorded API responses npm run test:e2e:replay # E2E (replay fixtures - recorded API responses) ``` You can run a single E2E Test file like the following: ```bash # Run tests in a single test file against live APIs npx playwright test test/e2e.../testfile.e2e.test.js --config=test/playwright.config.js --project=chromium # Run tests in a single test file while replaying recorded API responses from the fixtures npx playwright test test/e2e.../testfile.e2e.test.js --config=test/playwright.config.js --project=chromium-replay # Run tests in a single test file against live APIs and capture the API responses as fixtures for replay later npx playwright test test/e2e.../testfile.e2e.test.js --config=test/playwright.config.js --project=chromium-record ``` For more information on creating or running E2E tests see [test/TESTING.md](https://github.com/sahat/hackathon-starter/blob/master/test/TESTING.md) ## Changelog You can find the changelog for the project in: [CHANGELOG.md](https://github.com/sahat/hackathon-starter/blob/master/CHANGELOG.md) ## Contributing If something is unclear, confusing, or needs to be refactored, please let me know.

Dispute Resolution. Please read this Arbitration Agreement carefully. It is part of your contract with Company and affects your rights. It contains procedures for MANDATORY BINDING ARBITRATION AND A CLASS ACTION WAIVER.

Applicability of Arbitration Agreement. All claims and disputes in connection with the Terms or the use of any product or service provided by the Company that cannot be resolved informally or in small claims court shall be resolved by binding arbitration on an individual basis under the terms of this Arbitration Agreement. Unless otherwise agreed to, all arbitration proceedings shall be held in English. This Arbitration Agreement applies to you and the Company, and to any subsidiaries, affiliates, agents, employees, predecessors in interest, successors, and assigns, as well as all authorized or unauthorized users or beneficiaries of services or goods provided under the Terms.

Notice Requirement and Informal Dispute Resolution. Before either party may seek arbitration, the party must first send to the other party a written Notice of Dispute describing the nature and basis of the claim or dispute, and the requested relief. A Notice to the Company should be sent to: 221B Baker Street. After the Notice is received, you and the Company may attempt to resolve the claim or dispute informally. If you and the Company do not resolve the claim or dispute within thirty (30) days after the Notice is received, either party may begin an arbitration proceeding. The amount of any settlement offer made by any party may not be disclosed to the arbitrator until after the arbitrator has determined the amount of the award to which either party is entitled.

Arbitration Rules. Arbitration shall be initiated through the American Arbitration Association, an established alternative dispute resolution provider that offers arbitration as set forth in this section. If AAA is not available to arbitrate, the parties shall agree to select an alternative ADR Provider. The rules of the ADR Provider shall govern all aspects of the arbitration except to the extent such rules are in conflict with the Terms. The AAA Consumer Arbitration Rules governing the arbitration are available online at adr.org or by calling the AAA at 1-800-778-7879. The arbitration shall be conducted by a single, neutral arbitrator. Any claims or disputes where the total amount of the award sought is less than Ten Thousand U.S. Dollars (US $10,000.00) may be resolved through binding non-appearance-based arbitration, at the option of the party seeking relief. For claims or disputes where the total amount of the award sought is Ten Thousand U.S. Dollars (US $10,000.00) or more, the right to a hearing will be determined by the Arbitration Rules. Any hearing will be held in a location within 100 miles of your residence, unless you reside outside of the United States, and unless the parties agree otherwise. If you reside outside of the U.S., the arbitrator shall give the parties reasonable notice of the date, time and place of any oral hearings. Any judgment on the award rendered by the arbitrator may be entered in any court of competent jurisdiction. If the arbitrator grants you an award that is greater than the last settlement offer that the Company made to you prior to the initiation of arbitration, the Company will pay you the greater of the award or $2,500.00. Each party shall bear its own costs and disbursements arising out of the arbitration and shall pay an equal share of the fees and costs of the ADR Provider.

Additional Rules for Non-Appearance Based Arbitration. If non-appearance based arbitration is elected, the arbitration shall be conducted by telephone, online and/or based solely on written submissions; the specific manner shall be chosen by the party initiating the arbitration. The arbitration shall not involve any personal appearance by the parties or witnesses unless otherwise agreed by the parties.

Time Limits. If you or the Company pursues arbitration, the arbitration action must be initiated and/or demanded within the statute of limitations and within any deadline imposed under the AAA Rules for the pertinent claim.

Authority of Arbitrator. If arbitration is initiated, the arbitrator will decide the rights and liabilities of you and the Company, and the dispute will not be consolidated with any other matters or joined with any other cases or parties. The arbitrator shall have the authority to grant motions dispositive of all or part of any claim. The arbitrator shall have the authority to award monetary damages, and to grant any non-monetary remedy or relief available to an individual under applicable law, the AAA Rules, and the Terms. The arbitrator shall issue a written award and statement of decision describing the essential findings and conclusions on which the award is based. The arbitrator has the same authority to award relief on an individual basis that a judge in a court of law would have. The award of the arbitrator is final and binding upon you and the Company.

Waiver of Jury Trial. THE PARTIES HEREBY WAIVE THEIR CONSTITUTIONAL AND STATUTORY RIGHTS TO GO TO COURT AND HAVE A TRIAL IN FRONT OF A JUDGE OR A JURY, instead electing that all claims and disputes shall be resolved by arbitration under this Arbitration Agreement. Arbitration procedures are typically more limited, more efficient and less expensive than rules applicable in a court and are subject to very limited review by a court. In the event any litigation should arise between you and the Company in any state or federal court in a suit to vacate or enforce an arbitration award or otherwise, YOU AND THE COMPANY WAIVE ALL RIGHTS TO A JURY TRIAL, instead electing that the dispute be resolved by a judge.

Waiver of Class or Consolidated Actions. All claims and disputes within the scope of this arbitration agreement must be arbitrated or litigated on an individual basis and not on a class basis, and claims of more than one customer or user cannot be arbitrated or litigated jointly or consolidated with those of any other customer or user.

Confidentiality. All aspects of the arbitration proceeding shall be strictly confidential. The parties agree to maintain confidentiality unless otherwise required by law. This paragraph shall not prevent a party from submitting to a court of law any information necessary to enforce this Agreement, to enforce an arbitration award, or to seek injunctive or equitable relief.

Severability. If any part or parts of this Arbitration Agreement are found under the law to be invalid or unenforceable by a court of competent jurisdiction, then such specific part or parts shall be of no force and effect and shall be severed and the remainder of the Agreement shall continue in full force and effect.

Right to Waive. Any or all of the rights and limitations set forth in this Arbitration Agreement may be waived by the party against whom the claim is asserted. Such waiver shall not waive or affect any other portion of this Arbitration Agreement.

Survival of Agreement. This Arbitration Agreement will survive the termination of your relationship with Company.

Small Claims Court. Nonetheless the foregoing, either you or the Company may bring an individual action in small claims court.

Emergency Equitable Relief. Anyhow the foregoing, either party may seek emergency equitable relief before a state or federal court in order to maintain the status quo pending arbitration. A request for interim measures shall not be deemed a waiver of any other rights or obligations under this Arbitration Agreement.

Claims Not Subject to Arbitration. Notwithstanding the foregoing, claims of defamation, violation of the Computer Fraud and Abuse Act, and infringement or misappropriation of the other party’s patent, copyright, trademark or trade secrets shall not be subject to this Arbitration Agreement.

In any circumstances where the foregoing Arbitration Agreement permits the parties to litigate in court, the parties hereby agree to submit to the personal jurisdiction of the courts located within Netherlands County, California, for such purposes.

The Site may be subject to U.S. export control laws and may be subject to export or import regulations in other countries. You agree not to export, re-export, or transfer, directly or indirectly, any U.S. technical data acquired from Company, or any products utilizing such data, in violation of the United States export laws or regulations.

Company is located at the address in Section 10.8. If you are a California resident, you may report complaints to the Complaint Assistance Unit of the Division of Consumer Product of the California Department of Consumer Affairs by contacting them in writing at 400 R Street, Sacramento, CA 95814, or by telephone at (800) 952-5210.

Electronic Communications. The communications between you and Company use electronic means, whether you use the Site or send us emails, or whether Company posts notices on the Site or communicates with you via email. For contractual purposes, you (a) consent to receive communications from Company in an electronic form; and (b) agree that all terms and conditions, agreements, notices, disclosures, and other communications that Company provides to you electronically satisfy any legal obligation that such communications would satisfy if it were be in a hard copy writing.

Entire Terms. These Terms constitute the entire agreement between you and us regarding the use of the Site. Our failure to exercise or enforce any right or provision of these Terms shall not operate as a waiver of such right or provision. The section titles in these Terms are for convenience only and have no legal or contractual effect. The word "including" means "including without limitation". If any provision of these Terms is held to be invalid or unenforceable, the other provisions of these Terms will be unimpaired and the invalid or unenforceable provision will be deemed modified so that it is valid and enforceable to the maximum extent permitted by law. Your relationship to Company is that of an independent contractor, and neither party is an agent or partner of the other. These Terms, and your rights and obligations herein, may not be assigned, subcontracted, delegated, or otherwise transferred by you without Company’s prior written consent, and any attempted assignment, subcontract, delegation, or transfer in violation of the foregoing will be null and void. Company may freely assign these Terms. The terms and conditions set forth in these Terms shall be binding upon assignees.

================================================ FILE: test/TESTING.md ================================================ # Testing Guide This document describes the test organization, fixture system, and how to create and run new tests in the hackathon-starter project. ## Table of Contents - [Overview](#overview) - [Test Organization](#test-organization) - [Fixture System](#fixture-system) - [Running Tests](#running-tests) - [Creating New Tests](#creating-new-tests) - [Troubleshooting](#troubleshooting) ## Overview Hackathon Starter comes with core unit tests that focus on essential functionality, as well as end-to-end (E2E) tests using [Playwright](https://playwright.dev/) for various integrations. The purpose of the core unit tests is to verify core features like user management and security features. You usually don't need to worry about these during hackathons, but it's a good idea to keep them to ensure your customizations don't break core functions. The end-to-end tests are built around various integrations. Depending on your application, you may want to replace them with tests that apply to your implementation. You don't need to run or update the E2E tests during the hackathon. However, if you decide to further develop your idea with your team after the event, the E2E tests can help you avoid breaking existing functionality every time you modify your application or build a new feature. With Playwright, test automation uses its own web browser to browse various views in your application, interact with them, and check for expected results. You can use the existing tests as templates for developing your own Playwright tests. Hackathon Starter's current test helper tools enable you to run E2E tests against live APIs, or record and replay API responses for more predictable results or in environments that you can't access live APIs. ## Test Organization ``` test/ ├── fixtures/ # Fixtures are recorded API responses │ └── fixture_manifest.json # Registry of recorded tests ├── tools/ # Test utilities and fixtures │ ├── fixture-helpers.js # Shared fixture utilities │ ├── server-fetch-fixtures.js # Intercepts server-side fetch() calls │ ├── server-axios-fixtures.js # Intercepts server-side axios calls │ ├── playwright-start-and-log.js │ ├── simple-link-image-check.js │ └── start-with-memory-db.js # Test server with in-memory MongoDB ├── e2e/ # Tests requiring API keys │ ├── chart.e2e.test.js │ ├── foursquare.e2e.test.js │ ├── google-maps.e2e.test.js │ ├── here-maps.e2e.test.js │ ├── lob.e2e.test.js │ ├── nyt.e2e.test.js │ ├── openai-moderation.e2e.test.js │ ├── llm-classifier.e2e.test.js │ ├── trakt.e2e.test.js │ └── twilio.e2e.test.js ├── e2e-nokey/ # Tests that work without API keys │ ├── github-api.e2e.test.js │ ├── lastfm.e2e.test.js │ ├── pubchem.e2e.test.js │ ├── rag.e2e.test.js │ ├── scraping.e2e.test.js │ ├── upload.e2e.test.js │ └── wikipedia.e2e.test.js ├── app.test.js # Basic app structure tests - core unit test ├── app-links.test.js # Link validation tests - utility to identify broken links ├── contact.test.js # Contact form tests - core unit test ├── flash.test.js # Flash message tests - core unit test ├── models.test.js # Database model tests - core unit test ├── morgan.test.js # Morgan logger tests - core unit test ├── nodemailer.test.js # Email tests - core unit test ├── passport.test.js # Auth tests - core unit test └── playwright.config.js # Playwright configuration ``` ### Test Categories 1. **`test/e2e/`** - Integration tests that require API keys - These tests call third-party APIs (Foursquare, Twilio, OpenAI, etc.) - Can run in record mode (with keys) or replay mode (with fixtures) 2. **`test/e2e-nokey/`** - Integration or partial Integration tests that don't need API keys - Public APIs (GitHub, Wikipedia, PubChem) or local features (upload, RAG) - Can run without any configuration in replay mode 3. **Core Unit Tests** - Individual component tests (models, config, middleware) ## Running E2E Tests Use one script with project selection: ```bash npm run test:e2e:live # All E2E tests with live API calls npm run test:e2e:replay # All E2E tests with previously recorded API responses npm run test:e2e:custom -- --project=chromium-record # E2E with recording API calls (record fixtures) npm run test:e2e:custom -- --project=chromium-nokey-live # Only E2E tests that don't require API keys (live) npm run test:e2e:custom -- --project=chromium-nokey-replay # Only E2E tests that don't require API keys (replay fixtures) npm run test:e2e:custom -- --project=chromium-nokey-record # Only E2E tests that don't require API keys (record fixtures) ``` ### Run a Single E2E Test File ```bash # Run tests in a single test file against live APIs npx playwright test test/e2e.../testfile.e2e.test.js --config=test/playwright.config.js --project=chromium # Run tests in a single test file while replaying recorded API responses from the fixtures npx playwright test test/e2e.../testfile.e2e.test.js --config=test/playwright.config.js --project=chromium-replay # Run tests in a single test file against live APIs and capture the API responses as fixtures for replay later npx playwright test test/e2e.../testfile.e2e.test.js --config=test/playwright.config.js --project=chromium-record ``` ## Fixture System The fixture system allows tests to record API responses once and replay them deterministically. This eliminates the need for API keys in CI/CD and makes tests faster and more reliable. ### How It Works #### Server-Side Interception The E2E test framework in hackathon-starter is currently only for server-side API calls, not browser-side. The fixture system intercepts server-side HTTP libraries: 1. **`server-fetch-fixtures.js`** - Monkey-patches `globalThis.fetch()` 2. **`server-axios-fixtures.js`** - Uses axios interceptors Both are installed in `start-with-memory-db.js` for Playwright tests before the Express app loads for testing. #### Limitations and unsupported transports Record/replay supports only server-side `fetch()` and `axios` calls. Node's built-in (legacy) `http`/`https` modules, or browser-side API calls are currently not supported. #### Recording Mode (API_MODE=record) When recording, the system: 1. Lets API calls execute normally 2. Captures responses 3. Saves them to `test/fixtures/` with sanitized filenames (removes tokens and API keys by keyword matching) 4. Registers the test in `fixture_manifest.json` so the replay mode can check for missing fixtures **Fixture filenames** are generated by `keyFor()` in `fixture-helpers.js`: - URL is sanitized (sensitive query params like `apikey`, `token` are stripped by keyword matching) - For POST requests, a body hash is appended for uniqueness - Example filename: `GET_api.openweathermap.org_data_2.5_weather_q=Seattle.json` #### Replay Mode (API_MODE=replay) When replaying, the system: 1. Intercepts API calls before they hit the network 2. Returns saved fixture data instead 3. Falls back to real network if fixture is missing (unless `API_STRICT_REPLAY=1`) #### Strict Replay Mode (API_STRICT_REPLAY=1) With strict mode enabled: - Any request without a fixture is blocked with an error - Ensures tests never accidentally hit live APIs - Useful in CI/CD or to verify all fixtures exist ### Fixture Helpers **`test/tools/fixture-helpers.js`** provides shared utilities: - **`registerTestInManifest(testFile)`** - Self-registers test during record mode - **`isInManifest(testFile)`** - Checks if test is in manifest (for replay skip logic) - **`hashBody(body)`** - Creates SHA1 hash of request body for fixture keys - **`keyFor(method, url, body)`** - Generates sanitized fixture filename ## Creating New Tests 1. **Create the test file** in `test/e2e/` or `test/e2e-nokey/` 2. **Add fixture boilerplate** (if applicable - see existing tests for examples) 3. **Write your test assertions** 4. **Test and finalize your test against live APIs** ```bash npx playwright test test/e2e/my-api.e2e.test.js --config=test/playwright.config.js --project=chromium ``` 5. **Record fixtures** (first time only): ```bash npx playwright test test/e2e/my-api.e2e.test.js --config=test/playwright.config.js --project=chromium-record ``` 6. **Verify replay works**: ```bash npx playwright test test/e2e/my-api.e2e.test.js --config=test/playwright.config.js --project=chromium-replay ``` ### 3. Important Patterns #### API_TEST_FILE Environment Variable Always set this at the top of your test file if you are setting up Playwright tests that are going to have record and replay: ```javascript process.env.API_TEST_FILE = 'e2e/my-api.e2e.test.js'; ``` This tells the fixture system which test is currently running for fixture tracking. #### Self-Registration Pattern Tests self-register in the manifest during record mode: ```javascript registerTestInManifest('e2e/my-api.e2e.test.js'); ``` This enables you to let tests skip automatically when their fixtures haven't been recorded yet. #### Skip Logic for Replay Mode Skip tests that don't have fixtures recorded: ```javascript if (process.env.API_MODE === 'replay' && !isInManifest('e2e/my-api.e2e.test.js')) { console.log('[fixtures] skipping e2e/my-api.e2e.test.js - not in manifest - [number of tests in the file] tests'); test.skip(true, 'Not in manifest for replay mode'); } ``` #### Shared Page Pattern Use `beforeAll` with a shared page for better performance: ```javascript let sharedPage; test.beforeAll(async ({ browser }) => { sharedPage = await browser.newPage(); await sharedPage.goto('/api/my-api'); await sharedPage.waitForLoadState('networkidle'); }); test.afterAll(async () => { if (sharedPage) await sharedPage.close(); }); ``` ### 4. Tests Without Fixtures For tests that don't need fixtures (unit tests, local features): ```javascript const { test, expect } = require('@playwright/test'); test.describe('My Feature', () => { test('should work correctly', async ({ page }) => { await page.goto('/my-feature'); // Add assertions }); }); ``` No fixture boilerplate needed. ### 5. Skipping Tests in Record/Replay Mode Some tests (like Google Maps, HERE Maps) don't work well with fixtures and should skip entirely during record or replay modes: ```javascript if (process.env.API_MODE === 'replay' || process.env.API_MODE === 'record') { console.log('[fixtures] skipping my-test.e2e.test.js in record/replay mode'); test.skip(true, 'Skipping in record/replay mode'); } ``` ## Best Practices 1. **Always use fixtures for API tests** - Faster, more reliable, works in CI/CD 2. **Record with --workers=1** - Prevents race conditions and incomplete fixtures 3. **Self-register tests** - Use `registerTestInManifest()` pattern for automatic skipping 4. **Share pages when possible** - Use `beforeAll` with a shared page for performance and to reduce the chances of getting rate-limited by APIs 5. **Use descriptive test names** - Makes debugging easier 6. **Test one thing at a time** - Easier to understand failures 7. **Clean up after tests** - Close pages, delete temp files 8. **Use strict replay in CI** - Catch missing fixtures early 9. **Keep fixtures committed** - Other developers can run tests immediately 10. **Document API-specific quirks** - Add comments for unusual API behavior ================================================ FILE: test/app-links.test.js ================================================ const { expect } = require('chai');
