Hey there 👋

This module is really helpful, so first thanks for creating and maintaining it!

Unfortunately, there is no TypeScript declaration file included, and AFAICS there is also no typings package on @types. Could you imagine adding such a file to this module?

This would help a lot when this module is used from TypeScript.

PS: I could also imagine to come up with a PR, but I have seen that you are using flow, and I was not sure if you would like to have a TypeScript declaration file at all, so I just wanted to ask first.
