What is @angular/platform-browser?
The @angular/platform-browser package provides services that are essential for running Angular applications in a web browser. This includes DOM manipulation, rendering, and browser interaction APIs.
What are @angular/platform-browser's main functionalities?
DOM Manipulation
The BrowserModule provides services that are necessary for any web app, such as DOM rendering, sanitization, and location. It should be imported once in the root module of the app.
import { BrowserModule } from '@angular/platform-browser';
@NgModule({
imports: [BrowserModule],
...
})
export class AppModule { }
Browser Event Handling
The package allows components to handle browser events such as resize, keyup, and more through the HostListener decorator.
import { Component, HostListener } from '@angular/core';
@Component({...})
export class MyComponent {
@HostListener('window:resize', ['$event'])
onResize(event) {
// Handle the browser resize event
}
}
Safe Interpolation
The DomSanitizer service helps prevent Cross Site Scripting Security bugs (XSS) by sanitizing values to be safe to use in the different DOM contexts.
import { DomSanitizer } from '@angular/platform-browser';
@Component({...})
export class MyComponent {
safeUrl;
constructor(private sanitizer: DomSanitizer) {
this.safeUrl = this.sanitizer.bypassSecurityTrustResourceUrl('https://example.com');
}
}
