Angular Forms Skill

Rules

Form Creation

• Use ReactiveFormsModule for reactive forms
• Use FormControl for individual form fields
• Use FormGroup to group multiple form controls
• Use FormArray for dynamic lists of form controls
• Use FormBuilder for simplified form creation

Validation

• Use built-in validators: Validators.required, Validators.email, Validators.min, Validators.max, Validators.pattern
• Custom validators MUST return ValidationErrors | null
• Show validation errors ONLY after field is touched
• Disable submit button when form is invalid
