In this article, we’ll walk through how to validate checkboxes in Angular 17 using standalone components. This tutorial is also available as a YouTube video, which you can watch here:

Let’s dive in and see how to implement checkbox validation in a few simple steps.

Step 1: Create a New Component First, create a new component called CheckboxExampleComponent to hold the code related to the checkbox example. Use the Angular CLI command ng g c to generate the component folder and files:

ng g c checkbox-example

Step 2: Import the Forms Module Open the checkbox-example.component.ts file. Since we're using a standalone component, import the FormsModule directly in the imports array:

import { Component } from '@angular/core';
import { FormsModule } from '@angular/forms';
@Component({
selector: 'app-checkbox-example',
templateUrl: './checkbox-example.component.html',
styleUrls: ['./checkbox-example.component.css'],
standalone: true,
imports: [FormsModule]
})
export class CheckboxExampleComponent {
}
