Looks good to me,

You seem to use and or know a bit about typescript.
Can you tell me what this @types/xyz is on npm?
https://www.npmjs.com/~types

Looks like that's another way of providing type definitions besides pushing it to your own package and thus all consumers?

Thanks for this PR!

@ndelangen Yes, this scope is populated via: https://github.com/DefinitelyTyped/DefinitelyTyped/ which is the de-facto standard way to consume types for untyped packages. We could easily transfer all the included typings in this repo into definitely typed - I actually think that might be favourable, as we can make sure that the type definitions are kept up-to-date by more people, are more easily discoverable and can be installed optionally.

[ndelangen]

Cool, can you help us with this? What do you need from us / what do we need to do to make this work ?

[joscha]

First step is to open the PRs in definitely typed for the packages that currently have types. It usually takes a bit longer for new packages to be accepted. Then once we have a release in @types/xxx we can remove the typings in this repo for xxx.

[joscha]

I can start that process without any additional help I think - we just need to make sure that we keep the typings in sync during this process.

[ndelangen]

With your help, that should be do-able right? 😃

[shilman]

Awesome @joscha!! I'm sure we can come up with some smart way to ensure the types are up to date ... Right @ndelangen ;-)
