Can I perform cross-field validation with this skill?

Yes, it includes implementation patterns for comparing multiple fields, such as verifying that a 'password' and 'confirm password' field match within the same form schema.

Is the Signal Forms API ready for production use?

As of Angular v21, Signal Forms are considered experimental. For production applications requiring long-term stability, traditional Reactive Forms are still recommended.

Which Angular versions are supported by this skill?

This skill is specifically tailored for Angular v21 and above, as it utilizes the Signal Forms API introduced in that version.

How does Signal Forms handle asynchronous validation?

The skill provides patterns for 'validateHttp', allowing you to perform server-side checks (like username availability) that update the field's pending and error states reactively.

개발자 도구

Implements type-safe, reactive forms in Angular using the v21+ Signal Forms API for modern state management.

소개

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.
