An Angular 2 starter kit featuring Angular 2 (Router, Forms, Http, Services, Tests, E2E), Karma, Protractor, Jasmine, Istanbul, TypeScript, Typings, and Webpack by AngularClass.

If you're looking for Angular 1.x please use NG6-starter
If you're looking to learn about Webpack and ES6 Build Tools check out ES6-build-tools

This seed repo serves as an Angular 2 starter for anyone looking to get up and running with Angular 2 and TypeScript fast. Using a Webpack for building our files and assisting with boilerplate. We're also using Protractor for our end-to-end story and Karma for our unit tests.

  • Best practices in file and application organization for Angular 2.
  • Ready to go build system using Webpack for working with TypeScript.
  • Angular 2 examples that are ready to go when experimenting with Angular 2.
  • A great Angular 2 seed repo for anyone who wants to start their project.
  • Testing Angular 2 code with Jasmine and Karma.
  • Coverage with Istanbul and Karma
  • End-to-end Angular 2 code using Protractor.
  • Type manager with Typings

Table of Contents

File Structure

We use the component approach in our starter. This is the new standard for developing Angular apps and a great way to ensure maintainable code by encapsulation of our behavior logic. A component is basically a self contained app usually in a single file or a folder with each concern as a file: style, template, specs, e2e, and component class. Here's how it looks:

angular2-webpack-starter/
 ├──src/                       * our source files that will be compiled to javascript
 |   ├──main.ts                * our entry file for our browser environment

Getting Started

Dependencies

What you need to run this app:

  • node and npm (brew install node)
  • Ensure you're running the latest versions Node v4.1.x+ and NPM 2.14.x+

Once you have those, you should install these globals with npm install --global:

  • webpack (npm install --global webpack)
  • webpack-dev-server (npm install --global webpack-dev-server)
  • karma (npm install --global karma-cli)
  • protractor (npm install --global protractor)
  • typings (npm install --global typings)
  • typescript (npm install --global typescript)

Installing

  • fork this repo
  • clone your fork
  • npm install to install all dependencies
  • typings install to install necessary typings
  • npm run server to start the dev server in another tab

Running the app

After you have installed all dependencies you can now run the app. Run npm run server to start a local server using webpack-dev-server which will watch, build (in-memory), and reload for you. The port will be displayed to you as http://0.0.0.0:3000 (or if you prefer IPv6, if you're using express server, then it's http://[::1]:3000/).

server

# development
npm run server
# production
npm run build:prod
npm run server:prod

Other commands

build files

# development
npm run build:dev
# production
npm run build:prod

watch and build files

npm run watch

run tests

npm run test

run webdriver (for end-to-end)

npm run webdriver:update
npm run webdriver:start

run end-to-end tests

# make sure you have webdriver running and a sever for the client app
npm run e2e

Contributing

You can include more examples as components but they must introduce a new concept such as Home component (separate folders), and Todo (services). I'll accept pretty much everything so feel free to open a Pull-Request

TypeScript

To take full advantage of TypeScript with autocomplete you would have to install it globally and use an editor with the correct TypeScript plugins.

Use latest TypeScript compiler

TypeScript 1.7.x includes everything you need. Make sure to upgrade, even if you installed TypeScript previously.

npm install --global typescript

Use a TypeScript-aware editor

We have good experience using these editors:

Frequently asked questions

  • What's the current browser support for Angular 2 Beta?
  • Why is my service, aka provider, is not injecting parameter correctly?
    • Please use @Injectable() for your service for typescript to correctly attach the metadata (this is a TypeScript problem)
  • How do I run protractor with node 0.12.x?
    • please check out this repo to use the old version of protractor #146
  • Where do I write my tests?
  • How do I start the app when I get EACCES and EADDRINUSE errors?
    • The EADDRINUSE error means the port 3000 is currently being used and EACCES is lack of permission for webpack to build files to ./dist/
  • How to use sass for css?
  • loaders: ['raw-loader','sass-loader'] and @Component({ styles: [ require('./filename.scss') ] }) see issue #136
  • How do I test a Service?
  • See issue #130
  • How fo I add vscode-chrome-debug support?
  • The VS Code chrome debug extension support can be done via launch.json see issue #144
