Closes N/A
What I did
Support the new signal-based output function in Angular 17.3 and upwards in Storybook's helper types as
Meta
,StoryObj
orStoryFn
. I also ensured that TypeScript doesn't complain in Angular versions that don't support this feature.Please be aware that controls might not reflect the proper types when Signals are used. For component and property analysis, we are relying on Compodoc. Compodoc doesn't support the new output signal yet.
