How to export security and index rules from Firestore?

Question

I've set up multiple different indexes on my Firestore development database. Now, I would like to export them into the firestore.indexes.json so that the process of setting up prod environment would be easier. Is there a way to export those indexes using Firebase CLI? The same applies to security rules, although I know that I can copy paste them.

Answer 1

In your Firebase project folder execute this in the terminal:

firebase firestore:indexes > firestore.indexes.json

And it will save a file called firestore.indexes.json with your indexes.

You can then upload that file onto other Firebase projects.
