<div *ngIf="checkHomePage()>
and in TypeScript,
checkHomePage(): boolean {
return this.router.url == 'yourhomepageurl';
}
import { Router } from '@angular/router';
Include the router in the constructor and create a method within the class to access URL
constructor(router: Router) {
}
getUrl() {
return this.router.url;
}
Update the HTML code to
<div *ngIf="getUrl()">
Make sure to import the router into your component.
import { Router, ActivatedRoute } from '@angular/router';
If you do not have @angular/router installed, you can do so by running "npm install @angular/router". Once installed, inject the router into your component like this:
constructor(private route: ActivatedRoute, private router: Router) { }
You can now create a method that will return true for your specific URL:
return this.router.url === 'your URL'
Then simply call that method inside *ngIf="isYourPage()"
