如何删除 Google Cloud Firestore 中项目的所有 collections？

Question

I can delete one at a time within the console, but there is no option to delete multiple/all, and I've accidentally created about 100 collections for a single project.

Answer 1

One solution is to use a Cloud Function, as explained in the doc: Delete data with a Callable Cloud Function .

Once you deploy this function, you can call it directly from your mobile app or website to recursively delete documents and collections.

Answer 2

Thank you! @Renaud Tarnec

For anybody else, I used the following command line command:

firebase firestore:delete --all-collections
