Angular Forms Guide

What are Angular Forms?

Angular forms are a way to handle user input in Angular applications. They provide a way to collect, validate, and process user data.

Types of Forms in Angular

There are two main types of forms in Angular:

• Template-driven forms: These are simple forms that are driven by the template. They are easy to use and suitable for simple scenarios.
• Reactive forms: These are more complex forms that are driven by the component class. They provide more control and are suitable for complex scenarios.

Creating a Template-driven Form

To create a template-driven form, follow these steps:

<form #myForm="ngForm">
    <input type="text" name="username" ngModel required>
    <button type="submit">Submit</button>
</form>

In your component, you can access the form data using the `myForm` variable.

Creating a Reactive Form

To create a reactive form, you need to import `ReactiveFormsModule` in your application module:

import { ReactiveFormsModule } from '@angular/forms';

Then, create a form in your component:

import { FormGroup, FormBuilder } from '@angular/forms';

export class MyComponent {
    myForm: FormGroup;

    constructor(private fb: FormBuilder) {
        this.myForm = this.fb.group({
            username: ['', Validators.required]
        });
    }
}
