This is cool, thanks!

How aboutcreateTypePredicate? Or maybe even justtypePredicate, short enough to just inline it

constepic=(actions$:Observable<Action>)=>actions$.filter(typePredicate(myAction))

Another idea is to add some method to the action creator itself, liketest ormatch:

constepic=(actions$:Observable<Action>)=>actions$.filter(myAction.match)

The latter would be handy in reducers as well as an alternative toisType:

// beforeif(isType(action,myAction)){// ...}// afterif(myAction.match(action)){// ...}

What do you think?

I love the match method idea. I hadn't considered that. I'll make the changes.

👍@AlexanderOtavka Found this PR looking for a solution for your exact use-case (redux-observable epics)

Looks good!

Could you please also add a regular test, apart from typings test?

@aikoven Done!

Thanks! I'll make a release very soon.

You are welcome! I look forward to upgrading my project.
