Breaking Changes

forms

• The shape of SignalFormsConfig.classes has changed

  Previously each function in the classes map took a FieldState. Now
  it takes a Field directive.

  For example if you previously had:

  provideSignalFormsConfig({
    classes: {
      'my-valid': (state) => state.valid()
    }
  })
  

  You would need to update to:

  provideSignalFormsConfig({
    classes: {
      'my-valid': ({state}) => state().valid()
    }
  })
