Reactive Forms in Angular 10 - How to Create a Login Form using Reactive Forms

Learn the basics of reactive forms in Angular 10. In this tutorial, you'll look at how to Create a Login Form using Reactive Forms

Reactive forms are an alternative to creating forms in Angular. Most of the heavy lifting for creating reactive forms happens in the component class instead of the template (HTML file).

One of the big benefits of using reactive forms is that it makes testing easier. The reason for this is that all the code related to your form lives in the component class. Given this, you don’t need to access the template on your tests to test your form. Instead, you can simply write a unit test.

Module setup

The first step to implement a reactive form will be to import ReactiveFormsModule to your application’s module. This module can be imported from @angular/forms.

For simplicity purposes, as part of this example, I’ll be writing all the form related code inside the AppComponent. The following code snippet shows how to include the ReactiveFormsModule for you to start creating your first reactive form.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { ReactiveFormsModule } from '@angular/forms';
  declarations: [
  imports: [
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }
