# Contributor Covenant Code of Conduct

## Our Pledge

In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, sex characteristics, gender identity and expression,
level of experience, education, socio-economic status, nationality, personal
appearance, race, religion, or sexual identity and orientation.

## Our Standards

Examples of behavior that contributes to creating a positive environment
include:

* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members

Examples of unacceptable behavior by participants include:

* The use of sexualized language or imagery and unwelcome sexual attention or
 advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
 address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
 professional setting

## Our Responsibilities

Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.

Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.

## Scope

This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.

## Enforcement

Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at iamolegga@gmail.com. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.

Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.

## Attribution

This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

<p align="center">Idiomatic Session Module for NestJS. Built on top of <a href="https://npm.im/express-session">express-session</a> 😎</p>

This module implements a session with storing data in one of [external stores](https://github.com/expressjs/session#compatible-session-stores) and passing ID of session to client via `Cookie`/`Set-Cookie` headers.

If you want to store data directly in `Cookie`, you can look at [nestjs-cookie-session](https://github.com/iamolegga/nestjs-cookie-session).

## Example

Register module:

```ts
// app.module.ts
import { Module } from '@nestjs/common';
import { NestSessionOptions, SessionModule } from 'nestjs-session';
import { ViewsController } from './views.controller';

@Module({
  imports: [
    // sync params:

    SessionModule.forRoot({
      session: { secret: 'keyboard cat' },
    }),

    // or async:

    SessionModule.forRootAsync({
      imports: [ConfigModule],
      inject: [Config],
      //              TIP: to get autocomplete in return object
      //                  add `NestSessionOptions` here ↓↓↓
      useFactory: async (config: Config): Promise<NestSessionOptions> => {
        return {
          session: { secret: config.secret },
        };
      },
    }),
  ],
  controllers: [ViewsController],
})
export class AppModule {}
```

In controllers use NestJS built-in `Session` decorator:

```ts
// views.controller.ts
import { Controller, Get, Session } from '@nestjs/common';

@Controller('views')
export class ViewsController {
  @Get()
  getViews(@Session() session: { views?: number }) {
    session.views = (session.views || 0) + 1;
    return session.views;
  }
}
```

---

**BE AWARE THAT THIS EXAMPLE IS NOT FOR PRODUCTION! IT USES IN-MEMORY STORE, SO YOUR DATA WILL BE LOST ON RESTART. USE OTHER [STORES](https://github.com/expressjs/session#compatible-session-stores)**

---

See [redis-store](https://github.com/tj/connect-redis) example in `examples` folder.

To run examples:

```sh
git clone https://github.com/iamolegga/nestjs-session.git
cd nestjs-session
npm i
npm run build
cd examples/in-memory # or `cd examples/redis-store`
npm i
npm start
```

For Redis example, you should start Redis on localhost:6379.
If you have Docker installed you can start Redis image by `npm run redis` from `redis-store` directory.

## Install

```sh
npm i nestjs-session express-session @types/express-session
```

## API

### SessionModule

`SessionModule` class has two static methods, that returns `DynamicModule`, that you need to import:

- `SessionModule.forRoot` for sync configuration without dependencies
- `SessionModule.forRootAsync` for sync/async configuration with dependencies

### SessionModule.forRoot

Accept `NestSessionOptions`. Returns NestJS `DynamicModule` for import.

### SessionModule.forRootAsync

Accept `NestSessionAsyncOptions`. Returns NestJS `DynamicModule` for import.

### NestSessionOptions

`NestSessionOptions` is the interface of all options. It has next properties:

- `session` - **required** - [express-session options](https://github.com/expressjs/session#options).
- `forRoutes` - **optional** - same as NestJS buil-in `MiddlewareConfigProxy['forRoutes']` [See examples in official docs](https://docs.nestjs.com/middleware#applying-middleware). Specify routes, that should have access to session. If `forRoutes` and `exclude` will not be set, then sessions will be set to all routes.
- `exclude` - **optional** - same as NestJS buil-in `MiddlewareConfigProxy['exclude']` [See examples in official docs](https://docs.nestjs.com/middleware#applying-middleware). Specify routes, that should not have access to session. If `forRoutes` and `exclude` will not be set, then sessions will be set to all routes.
- `retries` - **optional** - `number` - by default if your session store lost connection to database it will return session as `undefined`, and no errors will be thrown, and then you need to check session in controller. But you can set this property how many times it should retry to get session, and on fail `InternalServerErrorException` will be thrown. If you don't want retries, but just want to `InternalServerErrorException` to be throw, then set to `0`. Set this option, if you dont't want manualy check session inside controllers.
- `retriesStrategy` - **optional** - `(attempt: number) => number` - function that returns number of ms to wait between next attempt. Not calls on first attempt.

### NestSessionAsyncOptions

`NestSessionAsyncOptions` is the interface of options to create session module, that depends on other modules. It has next properties:

- `imports` - **optional** - modules, that session module depends on. See [official docs](https://docs.nestjs.com/modules).
- `inject` - **optional** - providers from `imports`-property modules, that will be passed as arguments to `useFactory` method.
- `useFactory` - **required** - method, that returns `NestSessionOptions`.

## Migration

### v2

`express-session` and `@types/express-session` are moved to peer dependencies, so you can update them independently.
