How to send and set cookies in Angular 4?

Answer»

We can use the ngx-cookie-service node package to save cookies in Angular 4.

Use the following steps:
  • Install the node package with the following syntax:
    npm install ngx-cookie-service –save
  • Now, we have to add the cookies service to app.module.ts as a provider.
    @NgModule({
        ...,
        providers: [ CookieService ]
    })
  • Further, CONTINUE by importing and injecting it into a component.
    import { CookieService } from 'ngx-cookie-service';
    constructor( PRIVATE cookieService: CookieService ) { }
    ngOnInit(): void {
    this.cookieService.set( 'Test', 'Hello World' );
    this.cookieValue = this.cookieService.get('Test');
    }
19. What is eager loading in angular 4?

There are three types of loading namely eager loading, lazy loading, and preloading. In general, eager loading is a module that NEEDS to import into the Angular 4 application module by importing metadata of @NgModule decorator. Additionally, eagerly loading is useful for small size angular applications in which all feature modules will be loaded before starting of the application.
