Hi everyone! Did anyone manage to successfully get external type definitions for Firebase using ts2kt? I’m getting a partial output with several errors.

Hi Edouard, we have PR on review <https://github.com/Kotlin/js-externals/pull/22> which means some work is in progress.
What kind of errors do you get? Probably we might help you with

Hi Roman, thanks for getting back and pointing me to the PR. I’m interested in the types defined in
https://github.com/firebase/firebase-js-sdk/blob/master/packages/firestore-types/index.d.ts

If I run ts2kt on the raw file, I get

ts2kt: “ImportDeclaration” kind unsupported yet here! (firebase-firestore.d.ts11 to 17:70)

When I manually add the types (from https://github.com/firebase/firebase-js-sdk/blob/master/packages/app-types/index.d.ts) instead of using the import, I get

ts2kt: “TypeQuery” kind unsupported yet here!

referring to line 101 in the original file:

Promise: typeof Promise;

Any idea?

It seems like there is some work has to be done for ts2kt. The possible workaround might be comment typeof expression and put the actual type manually.

just tried that, no more errors but the output file is missing a lot of types

What kind of types? Do they exist in the original d.ts files?

[Edouard Goossens]

Yes, DocumentSnapshot for example
