Publish Typescript declaration file

Hi @dumbmatter.

Thanks for such an awesome module! I’m currently using this for some tests in a library of mine that I’m transitioning from JavaScript to Typescript. I was wondering if it would be possible to push a new release out with some Typescript declaration files. It shouldn’t be too hard to do since you’re using Typescript yourself. Just setting declaration: true and removing allowJs: true in tsconfig.json should do the trick.

@Dahaden thanks for the suggestion and the prototype code!

The problem I worry about with this is if you’re passing around IndexedDB variables in your application code, that code shouldn’t have to care that fake-indexeddb exists, so any difference in types between fake-indexeddb and IndexedDB could result in a lot of false positive TypeScript errors. Extension of your example.

Ultimately I think there’s not much to gain by doing anything other than using the built-in TypeScript IndexedDB types. Anything in fake-indexeddb that’s not in real IndexedDB is not part of the public API currently anyway. (For your example, IDBTransaction.commit actually does exist.) If eventually stuff is added to the public API like #50 or #51, then the fake-indexeddb types could just be like IDBFactory & { myAPI: () => void }.

I’m going to try to do a new release containing TypeScript types and maybe also moving to ES modules if that doesn’t cause too many issues. Working on that now in the v4 branch: https://github.com/dumbmatter/fakeIndexedDB/tree/v4
