Angular2 Universal Starter Kit

Enjoy Server Side rendering and Web Workers in your Angular2 Application

What we've got here

• Server Side rendering for instant page loading
• Entire Angular2 application is running in a Web Worker (UI always will be smooth)
• Preboot to catch browser events before Angular2 is ready to work (you can experiment with its options here)
• Webpack and its awesome Code Splitting feature which allows us to lazy load parts of an application.
• Live Reloading, a browser will be reloaded on any change in server or browser code. It works well for both a main thread and web workers.
• Typescript with Typings
• Linting with TSLint
• Express - de facto standard for Node.js web apps.
• PM2 - most advanced Node.js process manager
• Unit testing with Karma
• End-to-End testing with Protractor

Requirements

• node >= 4.2.0
• npm >= 3.0.0

Quick start

# clone the repo without git history 
git clone --depth 1 https://github.com/alexpods/angular2-universal-starter.git
 
# change current directory to angular2-universal-starter 
cd angular2-universal-starter
 
# install dependencies 
npm install
 
# run the production server 
npm start

Go to http://localhost:3000 in your browser.

You may want to stop or restart the production server:

# stop the production server 
npm stop
 
# restart the production server 
npm restart

Development with Live Reloading

# make sure that the production server is not running 
npm stop
 
# run the development server with live reloading support 
npm run dev

The development server will watch for any changes, make rebuilds and reload a browser. All built code will be kept in memory, so dist folder will not be generated (all means code for both client and server sides).

Turning server side rendering and web workers on/off

You can optionally turn server side rendering or web workers suport on/off. You just need to change HAS_SS and HAS_WW in constants.js here:

// ...
 
// Server side rendering. Set it to `false` to turn it of.
exports.HAS_SS = 'NG2_SS' in process.env ? process.env.NG2_SS === 'true' : true;
// For example:
// exports.HAS_SS = false;
 
// Web workers support. Set it to `false` to turn it of.
exports.HAS_WW = 'NG2_WW' in process.env ? process.env.NG2_WW === 'true' : true;
// For example:
// exports.HAS_WW = 'NG2_WW' in process.env ? process.env.NG2_WW === 'true' : false;
 
//...

If you're using a development server, you don't need to restart it. The development server will just make rebuild and apply new changes.

If you're using a production server (npm start), you also don't need to restart it. Just rebuild your sources (npm run build, if npm run build:watch is running you don't need to do anything).

Building

# build the project 
npm run build
 
# build the project and start watching for its changes 
npm run build:watch

Linting

# check the project (source files) 
npm run lint
 
# check the project and start watching for its changes 
npm run lint:watch

If you're not agree with the default rules (tslint.json), feel free to tell me about it.

Testing

The next command will run both unit and end-to-end tests.

For end-to-end tests you need to start Selenium Server first (see End-to-End Testing).

# run all tests (single run) 
npm test

Unit Testing

# run unit tests (single run) 
npm run unit
 
# run unit tests and start watch for changes 
npm run unit:watch
 
# run unit tests for specified directory (path must be relative to root directory) 
# currently you can specify paths only for "src" directory 
npm run unit src/app
 
# run unit tests for specified file and start watch for changes 
npm run unit:watch src/app/home.spec.ts

End-to-End Testing

For end-to-end tests you nedd to start Selenium Server (webdriver) first.

# start Selenium Server (webdriver) 
npm run webdriver:start
 
# run end-to-end test (single run) 
npm run e2e

Cleaning

# remove "dist" and "logs" folders 
npm run clean
 
# remove "dist" folder 
npm run clean:dist
 
# remove "logs" folder 
npm run clean:logs
