Reactive Forms
Forms with FormControl and validators
typescript
// Form setup
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
export class MyComponent {
myForm: FormGroup;
constructor(private fb: FormBuilder) {
this.myForm = this.fb.group({
name: ['', [Validators.required, Validators.minLength(3)]],
email: ['', [Validators.required, Validators.email]],
age: [null, [Validators.min(18)]]
});
}
onSubmit() {
if (this.myForm.valid) {
console.log(this.myForm.value);
}
}
}💡 Reactive forms provide more control and testability
⚡ Use FormBuilder for cleaner syntax
📌 Async validators for server-side validation
🔥 FormArray for dynamic form fields
