Angular Forms: Types, Advantages, and Differences

This Article helps you to Understand, Angular Forms: Types, Advantages, and Differences

An essential component of a web application are forms. Almost all applications include forms that users must fill out. It's a form that provides us with useful data that was provided by the user.

The form building methods provided by Angular Forms are two.
- Reactive Approach
- Template Driven Approach

Template Driven Approach
In this method, the conventional form tag is used to create forms. Angular automatically interprets and creates a form object representation for the tag. Controls can be added to the form using the NGModel tag. Multiple controls can be grouped using the NGControlGroup module.

Here is setup the form in the HTML template code and angular automatically infer the structure of  your form
A form value can be generated using the “form.value” object. Form data is exported as JSON values when the submit method is called. Basic HTML validations can be used to validate the form fields. In the case of custom validations, directives can be used. Arguably, this method is the simplest way to create an Angular App.

Model-Driven Forms, also known as Reactive Forms 
Here, we setup the HTML code, define the form's structure in TS Code, and manually connect all of these elements. Data flows between form controls and data models are directly managed by the component when using reactive forms. Unlike a template-driven technique, reactive forms are driven by code.

Building Blocks of Angular Forms
Whether you use a template-driven or reactive forms strategy, the Angular Forms module has three building components.
FormControl, FormGroup and FormArray
