This project was generated with Angular CLI version 6.2.9 (and updated to 7.2.1).
Run yarn to install dependencies, then run yarn build to build the production build with buildOptimizer enabled.
Serve the resulting artifacts in dist/build-optimizer-bug with a regular http-server and open the application in the browser. You can see, that it errors out without displaying anything.
Then, turn off buildOptimizer in angular.json and run yarn build again. Open the resulting artifacts in the browser again and see, that everything works as expected.
Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
Run ng test to execute the unit tests via Karma.
Run ng e2e to execute the end-to-end tests via Protractor.
