Use the `-prod` flag for a production build. ## Running unit tests Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io). ## Running end-to-end tests Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/). Before running the tests make sure you are serving the app via `ng serve`. ## Deploying to GitHub Pages Run `ng github-pages:deploy` to deploy to GitHub Pages. ## Further help To get more help on the `angular-cli` use `ng help` or go check out the [Angular-CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
