Play 2.6.0 + Angular with Angular-CLI + SBT - based build

This template contains standard distribution of Play Framework 2.6.0 along with UI built with Angular (possibly latest).

Angular 2 application is contained in separate directory ui and is scaffolded using Angular-CLI. I've found WebJars and Sbt-Web based frontend build to be too slow and limited for my liking, so SBT is linked with Angular-CLI to handle frontend build.

Build requirements

  • node: ^6.9.0
  • npm: ^3.10.0
  • angular-cli: ^1.0.0.rc.1 / @latest
  • Chrome (for tests)

These three are required globally. sbt-js-engine will not be supported (and why should it - it's not like you can develop in Angular without node and npm anyway).

Changes and things to know

There are some small albeit important deviations from standard distribution of PF 2.6.0 and they are mostly related to sbt build and testing harness:

  • sbt version was changed to 0.13.15 from 0.13.11
  • scala version was changed to 2.11.8 from 2.11.7
  • all sbt-web plugins were removed from project/plugins.sbt since Angular-CLI now handles frontend build
  • Play run hook UIBuildHook was added to project/ - it's job is handling node modules installation via npm and npm run build when Play is run in dev mode.
  • build.sbt file contains UI build tasks: npm modules installation and karma tests running along with Play tests
  • IntegrationSpec was removed, as Selenium Webdriver driven E2E tests are useless due to Protractor integration.
  • Protractor testing is handled using ProtractorSpec test class in test. I owe that part to unnamed chinese coder who already battled with the idea of running Protractor tests from SBT and failed, so that I didn't have to. Thank you buddy!
  • Changes in ui folder don't cause Play reloads, but are observed (and handled) by Angular-CLI when Play is running in dev mode.
  • Protractor and Angular 2 unit tests require Chrome as ChromeDriver is supported out-of-the-box by Angular-CLI (I will work on making phantomjs default headless test-runner again).

About the Angular 2 app:

  • If you want to serve Angular 2 app without Play you can do so by issuing npm run start in ui/ directory - this will run ng serve
  • As you probably noticed I am using SASS via Angular-CLI CSS Preprocessors support (cause it's awesome!)

Migration from beta angular-cli version of this seed (pre-march 2017):

  • Rules of angular-cli rc update apply to your ui project, check commit log to see changed files
  • Dropped silly dev flag passed to index view as I managed to find (duh!) --extract-css in Angular CLI's docs
  • Moved UI build output to public/ui directory to handle Issue #4 related to Play not refreshing files from unmanaged sources. That requires small changes in path given to Assets controller in Play views serving Angular App.

Migration from older version of this seed:

  • Rules of angular-cli update apply to your ui project
  • Try to match the structure of new ui directory
  • Refactor tests to use TestBed instead of inject, use async tests for Zone.js async tracking
  • Most probably main.ts will need some refactoring to match new one - we're using Angular 2 modules now.

Good luck!

Feel free to ask questions, post issues and even PRs if you find this seed broken or lacking in any way.
