How to Do Angular Reactive Form Validation

This article provides an example of simple form validation in Angular 9+ by building out a signup form.

• We’ll validate user inputs using Angular’s built-in Validators, a set of functions provided by the framework.
• We’ll access form control properties to manage which errors should show when.
• We’ll enable the submit button only when all form controls are valid.

Install Angular - Angular Environment Setup Process

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

1. Installing Node.js and npm
2. Installing Angular CLI
3. Creating workspace
4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

• Node.js
• npm Package Manager

Node.js

First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

1. npm -v

Installing Angular CLI

• Open Terminal/Command Prompt
• To install Angular CLI, run the below command:

1. npm install -g @angular/cli

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

• Using CLI
• Using Visual Studio Code

1. Using CLI

To create a workspace:

• Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
• Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:

1. Ng new YourAppName

• After running this command, it will prompt you to select from various options about the CSS and other functionalities.

• To leave everything to default, simply press the Enter or the Return key.

Decorator Based Reactive Forms in Angular 

When working with forms in Angular, we are provided with two choices:-
Template-driven forms
Model-based reactive forms
Each one has its own use case depending upon how complex the form is.
Template-driven forms are useful when it’s a simple form such as login and signup, but they don’t scale as much as reactive forms. If you have very basic and simple requirements, use template-driven forms. The main disadvantage here is, unit testing is quite complicated to do without the form model inside the component.
Reactive forms are more robust as they’re more scalable, reusable, and testable. Most of the heavy lifting is done from the component class by putting the instances of the input fields on the template, making it easier to unit test. If you use large data-oriented forms with complex business logic, always use reactive forms.
In this article, we will discuss the reactive forms approach with decorator based validation. But before going into that first I will explain how to work without the decorator approach.
