Not only because you need to deal with files in JavaScript. Also, because you need an API to test against before you can actually start coding. In this tutorial, we will learn how to do both. First, we will create a simple express server with just one route to accept file uploads. Afterward, we will create an angular application from scratch and build a beautiful file-upload component using the angular material ui-component-library. Here is what the final result will look like: ![image](https://raw.githubusercontent.com/LukasMarx/angular-file-upload/master/angular-file-upload-result.png) Ready? Let's start coding!

Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files. ## Code scaffolding Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`. ## Build Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `-prod` flag for a production build. ================================================ FILE: client/angular.json ================================================ { "$schema": "./node_modules/@angular/cli/lib/config/schema.json", "version": 1, "newProjectRoot": "projects", "projects": { "file-uploader": { "projectType": "application", "schematics": { "@schematics/angular:component": { "style": "scss" } }, "root": "", "sourceRoot": "src", "prefix": "app", "architect": { "build": { "builder": "@angular-devkit/build-angular:browser", "options": { "outputPath": "dist/file-uploader", "index": "src/index.html", "main": "src/main.ts", "polyfills": "src/polyfills.ts", "tsConfig": "tsconfig.app.json", "assets": [ "src/favicon.ico", "src/assets" ], "styles": [ "src/styles.scss" ], "scripts": [] }, "configurations": { "production": { "fileReplacements": [ { "replace": "src/environments/environment.ts", "with": "src/environments/environment.prod.ts" } ], "optimization": true, "outputHashing": "all", "sourceMap": false, "extractCss": true, "namedChunks": false, "aot": true, "extractLicenses": true, "vendorChunk": false, "buildOptimizer": true, "budgets": [ { "type": "initial", "maximumWarning": "2mb", "maximumError": "5mb" } ] } } }, "serve": { "builder": "@angular-devkit/build-angular:dev-server", "options": { "browserTarget": "file-uploader:build" }, "configurations": { "production": { "browserTarget": "file-uploader:build:production" } } }, "extract-i18n": { "builder": "@angular-devkit/build-angular:extract-i18n", "options": { "browserTarget": "file-uploader:build" } }, "test": { "builder": "@angular-devkit/build-angular:karma", "options": { "main": "src/test.ts", "polyfills": "src/polyfills.ts", "tsConfig": "tsconfig.spec.json", "karmaConfig": "karma.conf.js", "assets": [ "src/favicon.ico", "src/assets" ], "styles": [ "src/styles.scss" ], "scripts": [] } }, "lint": { "builder": "@angular-devkit/build-angular:tslint", "options": { "tsConfig": [ "tsconfig.app.json", "tsconfig.spec.json", "e2e/tsconfig.json" ], "exclude": [ "**/node_modules/**" ] } }, "e2e": { "builder": "@angular-devkit/build-angular:protractor", "options": { "protractorConfig": "e2e/protractor.conf.js", "devServerTarget": "file-uploader:serve" }, "configurations": { "production": { "devServerTarget": "file-uploader:serve:production" } } } } }}, "defaultProject": "file-uploader" } ================================================ FILE: client/browserslist ================================================ # This file is used by the build system to adjust CSS and JS output to support the specified browsers below. # For additional information regarding the format and rule options, please see: # https://github.com/browserslist/browserslist#queries # You can see what browsers were selected by your queries by running: # npx browserslist > 0.5% last 2 versions Firefox ESR not dead not IE 9-11 # For IE 9-11 support, remove 'not'. ================================================ FILE: client/e2e/src/app.e2e-spec.ts ================================================ import { AppPage } from './app.po';
