Comes with:
- Gruntfile configured for RiotJS and SCSS.
- Browserify transpiled to ES5 using BabelJS.
- Browser testing with PhantomJS.
Riot Tags and your client/app.js file are compiled together using Browserify, and transpiled to ES5 using BabelJS, so yes, you can use ES6.
All your js, tag, and scss files are found in client/. Everything compiles out to public/app.js and public/app.css. Best advice is to build your stuff in component folders. Look at client/example-component for a reference example.
Comes ready with frontend testing using mocha, chai, karma, and phantomjs. Simply run npm test, and karma will start. You must have phantomjs installed.
Sometimes, all you need to do is compile SCSS. Multiple grunt tasks for different use cases: grunt by itself will compile, and watch for changes; grunt css will only compiled SCSS; grunt js will only compile JS; and grunt build will compile everything, but not watch. So for you continuous integration scripts, you would use grunt build.
