localStorage is not defined (Angular Universal)

Question

I am using universal-starter as backbone.

When my client starts, it read a token about user info from localStorage.

@Injectable()
export class UserSe         


        

Answer 1

This is how we have it in our project, as per from this github comment:

import { OnInit, PLATFORM_ID, Inject } from '@angular/core';
import { isPlatformServer, isPlatformBrowser } from '@angular/common';

export class SomeClass implements OnInit {

    constructor(@Inject(PLATFORM_ID) private platformId: Object) { }

    ngOnInit() {
        if (isPlatformServer(this.platformId)) {
            // do server side stuff
        }

        if (isPlatformBrowser(this.platformId)) {
           localStorage.setItem('myCats', 'Lissie & Lucky')
        }
    }    
}
