Implements type-safe, reactive forms in Angular using the v21+ Signal Forms API for modern state management.
The Angular Signal Forms skill enables developers to harness the experimental Signal Forms API introduced in Angular v21. It provides comprehensive patterns for building reactive, schema-validated forms where writable signals serve as the single source of truth. By using this skill, developers can implement automatic two-way binding, complex cross-field validation, and dynamic form arrays with full type safety. It is ideal for developers looking to migrate from traditional Reactive Forms to a more modern, signal-based reactivity model while maintaining granular control over field states like touched, dirty, and invalid.
