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
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
