We will look at an example of angular 17 @switch @case example. This article goes in detailed on angular 17 conditional @switch example. Alright, let’s dive into the details.

Angular provides conditional statements using ngSwitch, ngSwitchCase, and ngSwitchDefault but, Angular 17 changed the condition statement flow with new syntax. You can use @switch, @case, and @default for the switch case condition in angular 17. You can see one be one example with output and a new conditional statement.

import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
  
@Component({
  selector: 'app-root',
  standalone: true,
  imports: [CommonModule],
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

}

<div class="container">
  
    <!-- Using @switch @case -->
    @switch (type) { 
        @case (1) {
          <div>One</div>
        } 
        @case (2) {
          <div>Two</div>
        } 
        @default {
          <div>Default</div>
        }
    }
  
    <!-- Using ngSwitch with ngSwitchCase -->
    <div [ngSwitch]="type">
      <div *ngSwitchCase="1">One</div>
      <div *ngSwitchCase="2">Two</div>
      <div *ngSwitchDefault>Default</div>
    </div>
