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');

    }
