Does anyone know how to type this properly -
Line 86 in 8322d80
I've tried with various methods, but couldn't figure out how to type return value of createAction, maybe somebody here got better luck.
What's the problem compared to other functions? This one takes no arguments and returns a string.
I meant that there is a problem with typing return value of createAction and not actionCreator.toString.
It even is not be a problem when writing library definitions (like for flow-typed) as it can be typed as callable, but I have no idea how to type such thing in the source code itself when using flow
The issue im talking about can be observed here
It's nearly impossible to type it. Check the TypeScript definitions, there are several tricks to support to the best we can, having the same functions with dozen of possible types (with or without payload, with or without metadatas, no payload reducer, payload reducer with one, two, three, four, five or six arguments).
This lib wasn't designed to be typed at all. I would rather consider thinking of a better typed API on top of it.
I don't know Flow at all right now unfortunately...
