What problem does it solve?
Signal Forms eliminate fragile, boilerplate-heavy form wiring by giving Angular v21+ a reactive, schema-driven way to manage field state, validation, and two-way binding.
Core Features & Use Cases
- Signal-backed form models: Use writable signals as the single source of truth and bind fields with automatic two-way updates.
- Schema-based validation (sync/async): Define validators per field, including conditional rules, cross-field checks, and HTTP-based async validation.
- Dynamic and conditional UI: Hide/disable/readonly fields based on other values and build arrays of fields with reactive add/remove patterns.
Use case: Create a login or onboarding wizard where email/password inputs validate instantly, errors render based on touched/invalid state, and optional fields appear only when prerequisites are met.
