Export json from Firestore

I just wrote a backup and restore for Firestore. You can have a try on my GitHub.

Thanks,

There is not, you'd need to come up with your own process such as querying a collection and looping over everything.

Update

As of August 7th, 2018, we do have a managed export system that allows you to dump your data into a GCS bucket. While this isn't JSON, it is a format that is the same as Cloud Datastore uses, so BigQuery understands it. This means you can then import it into BigQuery.

I've written a tool that traverses the collections/documents of the database and exports everything into a single json file. Plus, it will import the same structure as well (helpful for cloning/moving Firestore databases). Since I've had a few colleagues use the code, I figured I would publish it as an NPM package. Feel free to try it and give some feedback.

Google made it harder than it needed to be, so the community found a workaround. If you have npm installed, you can do this:

Export

npx -p node-firestore-import-export firestore-export -a credentials.json -b backup.json

Import

npx -p node-firestore-import-export firestore-import -a credentials.json -b backup.json
