The main purpose of Angular 8 forms is to handle the user’s input. You can also use these Angular forms in your application to enable users to log in, update profiles, enter information, or perform many other data-entry tasks.
There are two approaches to handle the user’s input through forms in Angular 8:
- Reactive forms
- Template-driven forms
Both approaches are used to collect user input events from the view, validate the user input, create a form model and data model to update, and provide a way to track changes.Angular 8, like its predecessors, uses forms to handle user input and manage the state of the application. The main purpose of Angular 8 forms is to facilitate the collection and validation of user input, as well as to manage the application state based on that input.Angular 8 provides two types of forms: Template-driven forms and Reactive forms.
- Template-driven forms:
- These are based on Angular template syntax.
- The form and its controls are defined in the HTML template.
- Angular automatically tracks and updates the form and its controls.
- Reactive forms:
- These are based on reactive programming principles.
- The form is defined programmatically in the component using TypeScript.
- Provides more flexibility and control over form behaviors.
In both cases, Angular forms allow you to:
- Capture user input.
- Validate and sanitize the input data.
- Track the state of the form and its controls.
- Interact with the user based on their input (e.g., show/hide elements, enable/disable buttons).
Angular forms play a crucial role in building dynamic and interactive web applications by managing user interactions and data flow effectively.
