Angular 10 isPlatformWorkerUi API

In this article, we are going to see what is isPlatformWorkerUi in Angular 10 and how to use it. The isPlatformWorkerUi API is used to get a platform id that represents a web worker UI platform.

Syntax:

isPlatformWorkerUi( platformId );

NgModule: Module used by isPlatformWorkerUi is:

• CommonModule

Return Value: It returns a Boolean Value stating whether a platform id represents a web worker UI platform.

Approach: 

• Create an angular app that to be used.
• Import isPlatformWorkerUi from @angular/core to the project.
• In app.component.ts, define the object which holds the Boolean value.
• Serve the angular app using ng serve to see the output.

Example 1:

app.component.ts

import { Component, Inject } from '@angular/core';
import { PLATFORM_ID } from '@angular/core';
import { isPlatformWorkerApp } from '@angular/common';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  isWorkerApp: boolean;

  constructor( @Inject(PLATFORM_ID) platformId: Object) {
    this.isWorkerApp = isPlatformWorkerApp(platformId);
    console.log(this.isWorkerApp);
  }
}

Output:

Example 2:

app.component.ts

import { Component, Inject } from '@angular/core';
import { PLATFORM_ID } from '@angular/core';
import { isPlatformWorkerApp } from '@angular/common';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  isWorkerApp: boolean;

  constructor( @Inject(PLATFORM_ID) platformId: Object) {
    this.isWorkerApp = isPlatformWorkerApp(platformId);
  }
}

app.component.html

<div *ngIf = 'isWorkerApp==false'>
    platform id does not represents a web worker UI platform.
</div>
