Mixing Angular2 and RxJS, using @ngrx/store for state management and Webpack for bundling

angular2-sandbox

The goal of this project is to get better at Angular2, TypeScript and RxJS. I have a background on multiple projects with both Angular1 and React (with Redux), using Babel / Webpack and other tools.

To bootstrap this project, I've used my own boilerplate topheman/webpack-babel-starter that I have adapted from Babel / Eslint to TypeScript / TSLint.

This is still a work in progress. At this time, I've released an example of state management via @ngrx/store (a redux-like in RxJS), coupled with RxJS Observable streams wired to Angular2 components. The next step will be to add some network requests involved.

I've kept the development workflow exactly the same as topheman/webpack-babel-starter's (build tasks, deployment ...).

What's in there ?

• Development / Build / Lint tasks
• TypeScript transpiler
• TSLint
• Angular2 / RxJS / @ngrx/store (with logs/devtools for time travel like redux-devtools)
• Sass support
• Ship a version of your site with sourcemaps (see demo)

ONLINE DEMO

###Install

git clone https://github.com/topheman/angular2-sandbox.git
cd angular2-sandbox
npm install

###Run

npm start

Goto http://localhost:8080

If you need to access from a remote device (such as a smartphone on the same network), just LOCALHOST=false npm start and your site will be accessible via your IP (which will be output on the terminal at launch).

###Build

The ./build directory is ignored by git, it will contain a dist directory which holds the distribution version of your website (the one that you will ship once built (more infos on topheman/webpack-babel-starter).

All the build tasks will create a built version of the project in the ./build/dist folder, cleaning it before making the build.

• npm run build
• npm run build-prod optimized / uglified version
• npm run build-prod-all will build:
  • production version (optimized / uglified)
  • a debuggable version accessible at /devtools shipping all the sourcemaps, to ease sharing transpiled source code

npm run serve-dist will serve your ./build/dist folder at http://localhost:3000 so that you could test the built version you just made.

Development modules such as ngrx/devtools or any loggers that are used to enhance developer's experience won't even be part of the final production bundle. They will be dropped after compilation step, thanks to webpack.DefinePlugin. This isn't as straightforward and clean as with webpack/Babel/ES6 (because of TypeScript typing system and Angular decorators) - see the issue.

###Linter

• tslint is running while you're developping, check your console for errors
• you can also launch it via npm run lint
• see tslint.json for the configuration, inspired by AngularClass/angular2-webpack-starter's

###Customizations

You can customize the behavior of the scripts by specifying environments vars like DEVTOOLS, SHOW_DEVTOOLS, NODE_ENV or LINTER:

• NODE_ENV by default at development, NODE_ENV=production when you npm run build-prod
• LINTER=false will disable the linter (enabled by default, ex: LINTER=false npm start)
• STATS=true will write stats.json profiling file on disk from webpack at build (disabled by default, ex: STATS=true npm run build)
• FAIL_ON_ERROR=true will break the build if any errors occurs (useful for CIs such as travis - at false in dev-server, at true when building)
• LOCALHOST=false to access via IP from other devices on the same network (ex: LOCALHOST=false npm start - default true)
• DEVTOOLS: By default at null. Used internally by npm run build-prod-all (you may not need that if you don't do OSS)
• SHOW_DEVTOOLS=false npm start lets you run with the devtools closed by default
• DEVTOOLS npm run webpack lets you run without the devtools
• By default the project is using awesome-typescript-loader (for better performance in development with watch mode and other things), you can get back to ts-loader, just setting AWESOME_LOADER=false - ex: AWESOME_LOADER=false npm start
