I can use JSDoc to declare typings within a single code block, but it would be great to get the typings from functions too. Right now all functions are typed as objects, so I don’t get any help from the editor when trying to call them, or calling them incorrectly.
Can you give me more details on how you are declaring typing inside of a workflow code block?
Also how are you thinking you'd want to call a workflow function?
Are you looking for type support for the argument data types that a workflow function is expecting to receive to call it correctly with data from previous blocks?
