Is this skill compatible with older Angular versions?

This skill focuses on the experimental Signal Forms API introduced in Angular v21+. It is not intended for use with legacy Template-driven or standard Reactive Forms.

How does it handle nested data arrays?

It provides specific implementation guides for nested objects and dynamic arrays using the applyEach utility for granular array item validation.

Does it work with UI libraries like Angular Material?

Yes, it includes specific implementation examples for integrating Signal Forms with Angular Material form fields and mat-error components.

Does it support custom validators?

Yes, the skill includes patterns for implementing custom validation logic and cross-field validation, such as password confirmation or custom regex checks.

Developer Tools

Implements type-safe, reactive forms in Angular using the v21+ Signals API and schema-based validation.

About

This skill empowers developers to leverage the latest experimental Signal Forms API in Angular v21+. It provides comprehensive patterns for creating type-safe form structures, defining validation schemas, and managing complex form states like nested objects and dynamic arrays. By automating the boilerplate associated with reactive forms, it ensures consistent implementation of validators, error handling, and OnPush change detection strategies while providing a cleaner, more reactive developer experience.

Key Features

Standardized UI patterns for error handling and field state properties (touched, dirty, valid)
Type-safe form state management using native Angular Signals
Schema-based validation with built-in rules like email, minLength, and pattern
Cross-field and custom validation logic implementation patterns
Support for complex data structures including nested objects and dynamic arrays
21 GitHub stars

Use Cases

Building complex multi-step forms with dynamic field requirements and array inputs
Modernizing legacy Angular Reactive Forms to the new Signals-based architecture
Implementing type-safe user registration and profile management systems
