Angular Resize Event


Angular 14 directive for detecting changes of an element size.

It is as simple as:

It internally uses browser native ResizeObserver. Therefore it is not supported in IE.

For Angular 11 you can use version 2.1.0 which internally uses uses ResizeSensor from CSS Element Queries that is supported in IE.

Using the library

Import the library in any Angular application by running:

`bash
$ npm install angular-resize-event
`

and then from your Angular AppModule:

`typescript
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

// Import the library module
import { AngularResizeEventModule } from 'angular-resize-event';

@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,

// Specify AngularResizeEventModule library as an import
AngularResizeEventModule
],
providers: [],
bootstrap: [ AppComponent ]
})
export class AppModule { }
`

Once your library is imported, you can use its resized directive in your Angular application:

`html



`

`typescript
import { Component } from '@angular/core';

// Import the resized event model
import { ResizedEvent } from 'angular-resize-event';

@Component({...})
class MyComponent {
width: number;
height: number;

onResized(event: ResizedEvent) {
this.width = event.newRect.width;
this.height = event.newRect.height;
}
}
``
