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:
`

Getting Started
Dependencies
What you need to run this app:
* node and npm (brew install node)
* Ensure you're running the latest versions Node v6.x.x+ (or v7.x.x) and NPM 3.x.x+
> If you have nvm installed, which is highly recommended (brew install nvm) you can do a nvm install --lts && nvm use in $ to run with the latest Node LTS. You can also have this zsh done for you automatically
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)
* typescript (npm install --global typescript)
Installing
* fork this repo
* clone your fork
* npm install webpack-dev-server rimraf webpack -g to install required global dependencies
* npm install to install all dependencies or yarn
* 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/).

`bash
development
npm run server
production
npm run build:prod
npm run server:prod
`
Other commands
$3
`bash

$3
`bash

`
$3
`bash

`
$3
`bash
update Webdriver (optional, done automatically by postinstall script)
npm run webdriver:update
this will start a test server and launch Protractor
npm run e2e
`
$3
`bash
this will test both your JIT and AoT builds
npm run ci
`
$3
`bash
npm run e2e:live
`
$3
`bash
npm run build:docker
`
Configuration
Configuration files live in config/ we are currently using webpack, karma, and protractor for different stages of your application
AoT Don'ts
The following are some things that will make AoT compile fail.
- Don’t use require statements for your templates or styles, use styleUrls and templateUrls, the angular2-template-loader plugin will change it to require at build time.
- Don’t use default exports.
- Don’t use form.controls.controlName, use form.get(‘controlName’)
- Don’t use control.errors?.someError, use control.hasError(‘someError’)
- Don’t use functions in your providers, routes or declarations, export a function and then reference that function name
- @Inputs, @Outputs, View or Content Child(ren), Hostbindings, and any field you use from the template or annotate for Angular should be public
External Stylesheets
Any stylesheets (Sass or CSS) placed in the src/styles directory and imported into your project will automatically be compiled into an external .css and embedded in your production builds.
For example to use Bootstrap as an external stylesheet:
1) Create a styles.scss file (name doesn't matter) in the src/styles directory.
2) npm install the version of Boostrap you want.
3) In styles.scss add @import 'bootstrap/scss/bootstrap.scss';
4) In src/app/app.module.ts add underneath the other import statements: import '../styles/styles.scss';
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 2.1.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:
* Visual Studio Code
* Webstorm 10
* Atom with TypeScript plugin
* Sublime Text with Typescript-Sublime-Plugin
$3
> Install Debugger for Chrome and see docs for instructions to launch Chrome
The included .vscode automatically connects to the webpack development server on port 3000.
Types
> When you include a module that doesn't include Type Definitions inside of the module you can include external Type Definitions with @types
i.e, to have youtube api support, run this command in terminal:
`shell
npm i @types/youtube @types/gapi @types/gapi.youtube
`
In some cases where your code editor doesn't support Typescript 2 yet or these types weren't listed in `tsconfig.json`, add these to "src/custom-typings.d.ts" to make peace with the compile check:
`es6
import '@types/gapi.youtube';
import '@types/gapi';
import '@types/youtube';
`
Custom Type Definitions
When including 3rd party modules you also need to include the type definition for the module
if they don't provide one within the module. You can try to install it with @types
`
npm install @types/node
npm install @types/lodash
`
If you can't find the type definition in the registry we can make an ambient definition in
this file for now. For example
`typescript
declare module "my-module" {
export function doesSomething(value: string): string;
}
`
If you're prototyping and you will fix the types later you can also declare it as type any
`typescript
declare var assert: any;
declare var _: any;
declare var $: any;
`
If you're importing a module that uses Node.js modules which are CommonJS you need to import as
`typescript
import * as _ from 'lodash';
`
Frequently asked questions
* What's the current browser support for Angular?
* Please view the updated list of browser support for Angular 2
* 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)
* Where do I write my tests?
* You can write your tests next to your component files. See /src/app/home/home.component.spec.ts
* 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({ styleUrls: ['./filename.scss'] }) see Wiki page How to include SCSS in components, or issue #136 for more information.
* How do I test a Service?
* See issue #130
* How do I add vscode-chrome-debug support?
* The VS Code chrome debug extension support can be done via launch.json see issue #144
* How do I make the repo work in a virtual machine?
* You need to use 0.0.0.0 so revert these changes #205
* What are the naming conventions for Angular?
* please see issue #185 and PR 196
* How do I include bootstrap or jQuery?
* please see issue #215 and #214
* How do I async load a component?
* see wiki How-do-I-async-load-a-component-with-AsyncRoute
* Error: Cannot find module 'tapable'
* Remove node_modules/ and run npm cache clean then npm install
* How do I turn on Hot Module Replacement
* Run npm run server:dev:hmr
* RangeError: Maximum call stack size exceeded
* This is a problem with minifying Angular and it's recent JIT templates. If you set mangle to false then you should be good.
* Why is the size of my app larger in development?
* We are using inline source-maps and hot module replacement which will increase the bundle size.
* If you're in China
* check out https://github.com/cnpm/cnpm
* node-pre-gyp ERR in npm install (Windows)
* install Python x86 version between 2.5 and 3.0 on windows see issue #626
* Error:Error: Parse tsconfig error [{"messageText":"Unknown compiler option 'lib'.","category":1,"code":5023},{"messageText":"Unknown compiler option 'strictNullChecks'.","category":1,"code":5023},{"messageText":"Unknown compiler option 'baseUrl'.","category":1,"code":5023},{"messageText":"Unknown compiler option 'paths'.","category":1,"code":5023},{"messageText":"Unknown compiler option 'types'.","category":1,"code":5023}]
* remove node_modules/typescript and run npm install typescript@beta. This repo now uses ts 2.0
* "There are multiple modules with names that only differ in casing"
* change c:\[path to angular2-webpack-starter] to C:\[path to angular2-webpack-starter]` see 926#issuecomment-245223547
