Local Testing - Firebase Realtime Database

[Kaan Soral]

Hello everyone,

I'm wondering whether this example can be emulated locally: https://cloud.google.com/solutions/using-firebase-real-time-events-app-engine

A related SO question: https://stackoverflow.com/questions/44149952/is-there-way-to-emulate-firebase-database-locally

There is a local emulator for the google cloud functions, yet I'm unsure whether it also has realtime database routines (for example, is there a local/testing version of the JS SDK, and so on)

Here's an old thread about testing and local database servers (mainly just about RTDB): https://groups.google.com/forum/#!msg/firebase-talk/Sl_aA0lSd78/Y7vNgFYACAAJ;context-place=topic/firebase-talk/CKM90JgJHI4

You can certainly use the (new) Cloud Functions shell to test database triggers locally:

https://firebase.google.com/docs/functions/local-emulator#use_the_cloud_functions_shell

You just need to provide the data that changed, and the function will pretend as if that database change occurred.

Thanks for the replies, however, as far as I understand, the realtime database itself can't be emulated locally (which would be a local server, local address, emulating the realtime database locally)

Coming from App Engine, this was a huge bummer, as you can replace almost all of App Engine's services locally

I assumed it was already available, spent 1-2 days seeking how it could be done, only to painfully discover it's not there

No, there is a way. See the link I posted above; you should try firebase-server. I've never figured out how to do authentication with firebase-server, though, so I've only used it for a few tests with the rules set to allow unauthenticated read/write.
