angular-forms
Build typed reactive forms with strict FormGroup typing, custom validators, and nonNullable controls in Angular. Use when implementing typed reactive forms, custom validators, or form control patterns. (triggers: FormBuilder, FormGroup, FormControl, Validators, reactive forms, typed forms)
Best use case
angular-forms is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Build typed reactive forms with strict FormGroup typing, custom validators, and nonNullable controls in Angular. Use when implementing typed reactive forms, custom validators, or form control patterns. (triggers: FormBuilder, FormGroup, FormControl, Validators, reactive forms, typed forms)
Teams using angular-forms should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Forms ## **Priority: P2 (MEDIUM)** ## 1. Use Strictly Typed Reactive Forms - Always use Reactive Forms over Template-Driven for complex inputs. - Define typed `FormGroup<T>` with explicit control types — never use untyped FormGroup. See [typed forms](references/typed-forms.md) for typed FormGroup examples. ## 2. Extract Validation Logic - Create standalone validator functions in a separate file. - Sync `valueChanges` to stores using `takeUntilDestroyed()`. See [typed forms](references/typed-forms.md) for standalone validator examples. ## 3. Ensure NonNullable Controls - Use `fb.nonNullable.group(...)` or `nonNullable: true` on individual controls. - This ensures form values are always strings — avoids null in form values. ## Anti-Patterns - **No Template-Driven Forms**: Use Reactive Forms for any non-trivial inputs. - **No untyped FormGroup**: Always use strictly typed `FormGroup<T>`. - **No validation in component**: Extract into standalone validator functions. ## References - [Typed Forms](references/typed-forms.md)
