Estructura de Archivos

We use the component approach in our sub project. 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:

angular/
 ├──config/                        * our configuration
 |   ├──helpers.js                 * helper functions for our configuration files
 |   ├──spec-bundle.js             * ignore this magic that sets up our Angular testing environment
 |   ├──karma.conf.js              * karma config for our unit tests
 |   ├──protractor.conf.js         * protractor config for our end-to-end tests
 │   ├──webpack.dev.js             * our development webpack config

 │   │   ├──app.e2e.ts             * a simple end-to-end test for /

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)
  • tslint (npm install --global [email protected])

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/).

Configuration

Configuration files live in config/ we are currently using webpack, karma, and protractor for different stages of your application

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 2.7.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:

Visual Studio Code + Debugger for Chrome

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.

Frequently asked questions

  • What's the current browser support for Angular?
  • 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?
  • 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?
  • 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?
  • How do I include bootstrap or jQuery?
  • How do I async load a component?
  • 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)
    • often happens when you're behind proxy and proxy wasn't configured in the npm as it tries to download binary package from the github and if it fails to do so, it will try to compile node-sass from the source codes
    • install Python x86 version 2.x and 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 [email protected]. This repo now uses ts 2.0
  • "There are multiple modules with names that only differ in casing"
