Ng-News 25/33: Signal Forms - First Public Demo

Angular’s most anticipated feature - Signal Forms - just got its first public demo. Plus: Zoneless goes stable, NgRx v20, and much more in this packed Angular update.

Signal Forms: First Public Demo

The monthly Angular Q&A with Mark Thompson session took place - but this time with a twist. Instead of Jeremy Elbourn co-hosting as usual, Alex Rickabaugh, the Angular Framework Lead, joined the session.

The main highlight of the session was the first public demo of Signal Forms, the upcoming third forms module - alongside Reactive Forms and Template-driven Forms.

Signal Forms is fully based on Angular Signals and, without a doubt, the most anticipated feature this year.

Comparison to existing Form Modules

Here’s an extremely simplified comparison:

• Like Template-driven Forms, -style bindings directly update the data object - but here, it’s a Signal.

• Like Reactive Forms, validators are defined in TypeScript, not in the template via directives.

• Unlike either, you don’t need to deal with or .

• Just structure your data as a Signal and add rules around it.

A New Validation System

The validation system in Signal Forms was built from scratch. Alex described it more like a DSL than a traditional validator setup and didn't even call it validation, but schema.

It is compatible with standard schema, which means libraries that support that standard - like Zod or Vest - can also be used.

Template Integration

And in templates? You’ll use the directive to bind to specific fields from the Signal data model.

A lot of buzz came from a PR mentioning two new Signal types: and (later renamed to and then ).

However, these are meant for internal use - for example in Signal Forms - and won’t be made public.

But… Alex did tease a potential new public Signal: .
