Indiana Jones and the Hidden Secrets of the Forms API
summary
Importing ReactiveFormsModule exposes built-in validators (email, required, maxlength, pattern), directives like FormControlName and FormGroupName, and utilities such as FormBuilder and the AbstractControl API with valueChanges and status observables. ControlValueAccessor lets custom or third‑party/web components act as form controls, while ControlContainer enables accessing parent form groups across components or routes. Use setValidators and updateValueAndValidity to change requiredness dynamically, and FormArray.push/insert/remove to build or tear down repeatable form sections.
