Angularfire: Can't find module: @firebase/firestore-types/index

[karsonbraaten]

import { Timestamp } from '@firebase/firestore-types'; appears to work in the project (linting, and can click through the import to the definition in VSCode) but it throws an error during compilation. I apologize if this is an issue with firebase and not angularfire but hopefully someone knows how to make this work or what the problem is.

Version info

Angular: 6.0.1
Firebase: 5.0.3
AngularFire: 5.0.0-rc.9

How to reproduce these conditions

https://stackblitz.com/edit/cannot-find-firestore-types

Expected behavior

No errors

Actual behavior

Can't find module:
@firebase/firestore-types/index (@0.4.2)

Check your import statements & ensure you're importing the correct module names.

We're only depending on firebase and it's public-types now (RC 10). We'd advise the same, rather than using @firebase/firestore-types, as we've been advised by the JS SDK team that those are only intended for internal use.

import { firestore } from 'firebase/app';
...
firestore.Timestamp
