SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Angular developers often struggle to keep form state, validation, and UI updates consistent when forms become complex, dynamic, or need strong typing.

Core Features & Use Cases

  • Type-safe form models with writable signals: Create a single source of truth for your form values using Angular signals.
  • Schema-based, reactive validation: Define validators (required, email, min/max, patterns) and validate individual fields or the whole form in a reactive way.
  • Dynamic UI state & advanced behaviors: Handle touched/dirty/disabled/hidden/readonly states, cross-field checks, async validation, and dynamic arrays of fields.

Use case example: Build a login + profile flow where email/password are validated instantly, errors render based on touched state, and a username field runs async “availability” checks before enabling submission.

Quick Start

Use the angular-forms skill to implement a Signal Forms model and validation schema for an Angular login form with immediate, per-field error messages and a disabled submit button until valid.

FAQPage Schema
How do I build type-safe Angular Signal Forms with schema-driven validation?▼

Build type-safe Angular Signal Forms by using writable signal models as a single source of truth and defining validation schemas with required, email, min/max, and pattern validators. This approach ensures form values remain strongly typed during reactive validation.

What is the best way to handle dynamic form state like touched, dirty, and disabled in Angular?▼

Handle dynamic form state like touched, dirty, disabled, hidden, and readonly in Angular by using signal-based state rendering patterns. Writable signals manage field-level state reactively, ensuring UI updates stay consistent without manual change detection.

Can I perform async validation for username availability checks in Angular Signal Forms?▼

You can perform async validation in Angular Signal Forms by integrating validateHttp or submit flows into your schema. This allows you to execute field-level async checks, such as username availability, before enabling form submission.

How do I implement cross-field validation checks in a reactive Angular form?▼

Implement cross-field validation checks in a reactive Angular form by applying schema-driven validators to the form object. This validates the entire form reactively, ensuring dependencies between multiple fields are checked before submission.

Does this reactive validation approach support dynamic arrays of fields?▼

Yes, this reactive validation approach supports dynamic arrays of fields. Schema definitions combined with writable signal models allow you to add, remove, and validate dynamic multi-field UIs while maintaining strict type safety.
