SASS is used to help the CSS development and the JavaScript is run through browserify/babel to allow for writing ES6 code. Both of these are done using gulp. To run the build task you can use the following commands:
``` bash
-# Build and minify for production
+# Build assets for development
npm run-script build
+# Build and minify assets for production
+npm run-script production
+
# Build for dev (With sourcemaps) and watch for changes
npm run-script dev
```
