In the official firebase documentation you can find how to export firestore data from your Google cloud account.
I'm using emulators locally. Is there a way to export firestore data from the emulator?
Thank you!
Yes, there is a proper documentation for importing/exporting Firestore data from the emulator you may refer to this link Export and import emulator data.

Scenario:
I am working on a POC locally where I am using Firestore as my database. As it is my local setup I am using Firestore Emulator. Now my POC is successful and I want to move local database from emulator to actual Firestore.
Query:
Is it possible to achieve what I am trying to do?
So far I am not able to find any relevant content on internet around this. I did find couple of examples where there is demonstration of exporting data from Firestore and importing to local emulator but I was not able to find the vice-versa option!
Firebase does not provide any sort of tool or service to do this. Your easiest alternative will be to write a program to query the data out of the emulator and write it into your cloud hosted instance. You might find the Firebase Admin SDK helpful for writing to the cloud in a program that you run locally.
I use Firebase emulators with the auth emulator (very happy with this new feature!)
I signup a user using email and password -> I can see it created in the emulator UI.
I insert some data in Firestore -> it works equally well.
I export the data:
firebase emulators:export local_data
Later on, I restart the emulators with the exported data:
firebase emulators:start --import=local_data
The Firestore data is loaded correctly, but the user I created previously does not exist!
It seems that the auth emulator data is not exported or not imported.
Am I doing something wrong?
Edit: this feature has been implemented by Firebase!
With CLI version > 9.1.0 one can export and import auth data from the emulators, cool!
see this Github announcement
According to the documentation:
emulators:export export_directory
Cloud Firestore or Realtime Database emulator. Export data from a running Cloud Firestore or Realtime Database emulator instance
So the emulators:import and emulators:export commands currently only work on Cloud Firestore and Realtime Database. As Doug commented, it is a valid feature request, so thanks for filing it on the Github repo.
I'm Planning To Use Firebase - Firestore Emulators For Handling Some Huge Amount Of Data That's Coming From A Websocket.
I just need to process the data locally in realtime.
Firestore Emulator Is A great choice since it has all the features I need. But the issue is it clears the database every time the Emulator is turned off. is there any config or settings that can change this behaviour?
if it is not possible. can somebody tell me any other Approach to use firestore locally? or any other alternative to firebase that I can use locally.
With the recent updates to Firebase Emulator, you use export the data when the emulator is running and import when it starts again.
To export the data
firebase emulators:export <export-directory>
To start and import the emulator
firebase emulators:start --import <export-directory>
I've managed this starting Firebase emulator with parameters to export data on exit and import existing one:
firebase emulators:start --import=exported-dev-data --export-on-exit=exported-dev-data
This way the emulator always export the data I've generated to folder exported-dev-data, and loads it back when starting again.
Currently you need to write code to populate the database during each run of the emulator.
If you would like to see different behavior, please file an issue on GitHub.
In general, the way I've been thinking about setting up a test database is creating two projects for DEV and PROD. Rather than creating a custom script is there any known process for import/export for cloud Firestore?
The supported export and import procedures are documented in detail. You use the gcloud command line.
Use the firestore export command to export all the documents in your
database, replacing [BUCKET_NAME] with the name of your Cloud Storage
bucket. Add the --async flag to prevent the gcloud tool from waiting
for the operation to complete.
gcloud alpha firestore export gs://[BUCKET_NAME]
Use the firestore import command to import documents from a previous
export operation.
gcloud alpha firestore import gs://[BUCKET_NAME]/[EXPORT_PREFIX]/
I want to connect my laravel app with google cloud datastore and want to use same data for android and ios application, for that i want to use firebase.
Can any one have idea that how can i access my google cloud datastore's data in firebase ?
You could try using Cloud Functions for Firebase to fetch/query data for you using the Node.js client libraries.
Documentation:
Google Cloud Node SDK for Cloud Datastore
Cloud Functions for Firebase
You could also try Cloud Functions for Firebase and/or Firestore DB instead of Google Cloud Datastore.
Firestore is the next evolution of Firebase (Realtime DB) with better support for scaling & data modeling + offline data management.
