This project was generated with Angular CLI version 1.0.0. This project explains angular 4 reactive forms
In a sense, instead of binding Object models to directives like template-driven forms, we in fact boot up our own instances inside a component class and construct our own JavaScript models. This has much more power and is extremely productive to work with as it allows us to write expressive code, that is very testable and keeps all logic in the same place, instead of scattering it around different form templates.
FormControl is a class that powers an individual form control, tracks the value and validation status FormGroup is a group of FormControl instances, also keeps track of the value and validation status
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/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.
Before running the tests make sure you are serving the app via ng serve.
