How to Validate Checkbox Selection in Angular 17 Using Standalone Components

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 {
}
