I updated several pieces:

• Play 2.6.0
• Scala 2.12.2
• TypeScript 2.4.1
• Webpack 3.0.0
• Angular 4.2.5
• RxJS 5.4.1

I also changed the target for transpiled JS to ES6. If you want to use ES5 you will need to add some extra polyfills.

There is an known issue related to RxJS and TypeScript (ReactiveX/rxjs#2539):

error TS2415: Class 'Subject<T>' incorrectly extends base class 'Observable<T>'

The idea of this project is to show a basic Play! application integrated with Webpcak for development. You can use it as a seed or just copy an paste code fragments into your own project.

When using SBT run command, a Node server for Webpack will be also started on port 8080. You can change this in the file webpack.server.js.

The TypeScript/JavaScript application is intended to be placed in the path ./app/frontend of this project. This code will be transpiled into a bundle file under ./public/bundles that will be included in the final Play! package when using sbt dist.

As this is intended to be a single page application all HTML templates have been removed from Play! and all controllers are used to serve static/Webpack files. You can extend them to build a REST API to be used by the JavaScript app.

The single page for the web application is under ./public/index.html.

The TypeScript entry point is under ./app/frontend/app/main.ts.

All Node modules are installed under ./app/frontend/node_modules and you should run npm commands under ./app/frontend. Other commands as typings (the new version of tsd).

To install TS/JS dependencies, including Angular and TypeScript, use npm install

This process will also transpile the single web app into JavaScript bundles using Webpack.

Use sbt dist.

This will create a Universal package (zip file) under target/universal/.

To test this package, unzip it and run .../bin/package_name.

Use sbt run

This will launch Webpack server (a NodeJS server running webpack) and Play! server.

Use ctrl + C to stop the server. This will stop both servers.

If you use ctrl + D to stop the process, this will only stop SBT and Play! server and you will need to terminate the Webpack server manually. One way to do this is: locate the process with ps -x | grep webpack and then kill -9 [processNumber] using the number returned by the previous command.

• SBT
• Play
• Scala
• Node
• TypeScript
• Webpack
• Angular
• RxJS

Add Test configuration for both, Scala and JavaScript
