Signal-based reactive forms for Angular v21+ with automatic two-way binding and schema-based validation. Build type-safe, reactive forms using Angular's Signal Forms API. Signal Forms provide automatic two-way binding, schema-based validation, and reactive field state. Note: Signal Forms are experimental in Angular v21. For production apps requiring stability, see references/form-patterns.md for Reactive Forms patterns. Form models are writable signals that serve as the single source of truth: Each field provides reactive signals for validation, interaction, and availability: The form itself is also a field with aggregated state: For Reactive Forms patterns (production-stable), see references/form-patterns.md . - Provides type-safe form creation using writable signals as the single source of truth, with automatic field state management for validation, interaction, and availability - Includes built-in validators (required, email, min, max, pattern) plus custom, cross-field, and async HTTP validation with conditional logic - Supports dynamic arrays, nested objects, hidden/disabled/readonly fields, and form-level state aggregation across all interactive fields - Experimental API recommended for new projects; production apps should reference Reactive Forms patterns for stability
