Angular Forms
Imagine you are filling out a job application form. You enter your name, email, and experience. The form checks if you filled everything correctly – if not, it shows errors. This is exactly what forms in Angular do: they capture user input, validate it, and handle submission.
Angular provides two approaches to building forms:
- Template-Driven Forms – Simple, mostly defined in the template. Good for basic forms.
- Reactive Forms – More powerful, defined in the component class. Better for complex forms and testing.
Setup
Before using forms, you need to import the appropriate module.
For template-driven forms, add
FormsModule to your module imports:import { FormsModule } from '@angular/forms';
@NgModule({
imports: [
FormsModule,
// other imports
]
})
For reactive forms, import
ReactiveFormsModule:import { ReactiveFormsModule } from '@angular/forms';
@NgModule({
imports: [
ReactiveFormsModule,
// other imports
]
})
You can also import both if your app uses both types.
Two Minute Drill
- Forms capture and validate user input.
- Two approaches: Template-Driven and Reactive.
- Template-driven: defined in template, use FormsModule.
- Reactive: defined in component class, use ReactiveFormsModule.
- Choose based on complexity and testing needs.
