  • Ahead of Time (AoT) compile for rapid page loads of your production builds.
  • Tree shaking to automatically remove unused code from your production bundle.
  • Webpack DLLs dramatically speed your development builds.
  • Testing Angular code with Jasmine and Karma.
  • Coverage with Istanbul and Karma
  • End-to-end Angular code using Protractor.
  • Type manager with @types
  • Hot Module Replacement with Webpack and @angularclass/hmr and @angularclass/hmr-loader
  • Material Design with angular/material2
  • Angular 4 support via changing package.json and any future Angular versions

Quick start

Make sure you have Node version >= 6.0 and NPM >= 3

Clone/Download the repo then edit app.component.ts inside /src/app/app.component.ts

# install the repo with npm
npm install

# start the server
npm start

# use Hot Module Replacement
npm run server:dev:hmr

# if you're in China use cnpm

go to http://0.0.0.0:3000 or http://localhost:3000 in your browser

Assessment: Overview

  • You will be coding a frontend template of a e-commerce platform
  • You will need to try create a pixel perfect project based on the supplied designs guidelines on Invision.
  • You have the option to theme the store as you like. The world is your oyster :)
  • All images can be found already sliced in the assets folder under "src/assets/img/"
  • Use Invision inspect to analyze the designs and get css hints and guides.
  • Extra merit will be rewarded to individuals who code the project in a modular component style. (hint - seperate css and structured file structure for components)
  • The home page component currently exists with a few helper blank components to help you.
  • Additinal challenge: Instead of hard coding the content create a json file with the variable parameters that populates the component with data. (examples are there for you to try)
  • Create your own github repository and commmit your changes at the end of every coding session.
  • Read this documentation very carefully as it will help you get up to speed with the project.
  • Good Luck

Assessment Task 01

  • Clone/Download the repo then edit app.component.ts inside /src/app/app.component.ts
  • Code the homepage layout. Make the header and footer seperate modules as well as the slider and product block.
  • Setup and configure the premium Royalslider carousel plugin and ensure that it is compatible with angular by using the angular royalslider directive.
  • Code the single product template, think carefully of the router url structure here as planning the architecture of this project will be essential in getting good marks.
  • Code the contact page template.
  • Use Invision to help you get the css properties of the designs seeing as you dont have access to photoshop. You will want to use the inpect tool on the design prototypes. see the invision access details and info below.

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/

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/).

server

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

Other commands

# this will start a test server and launch Protractor
npm run e2e

continuous integration (run unit tests and e2e tests together)

# this will test both your JIT and AoT builds
npm run ci

run Protractor's elementExplorer (for end-to-end)

npm run e2e:live

build Docker

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 + 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.

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:

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:

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

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

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

import * as _ from 'lodash';

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?
  • 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 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.
