Run firebase emulators:start --only functions

[alexpchin]

[REQUIRED] Environment info

13.3.1

firebase-tools:

macOs

Platform:

[REQUIRED] Test case

[REQUIRED] Steps to reproduce

When running firebase emulators:start --only functions I see: function ignored because the firestore emulator does not exist or is not running.

[REQUIRED] Expected behavior

I would expect to be able to run the emulated functions but connecting to a live firestore database.

[REQUIRED] Actual behavior

It seems like you can only run the functions emulator with the firebstore emulator?

Hey @alexpchin, thanks for reaching out. Let me know if I may be wrong here, but from what I can tell, you’re trying to trigger local functions based on production events. If so, this is not possible. A detailed explanation can be found in https://github.com/firebase/firebase-tools/issues/1962#issuecomment-583498789.

However, if you’re trying to read/write data from/to production, you could use the Firebase Admin SDK.

Hello @aalej Please can you re-open. I'm not trying to trigger local functions based on production events. I've got some firebase functions that are callable, http etc. What I want to be able to do is to call the functions from a localhost endpoint but for them to use the production firebase credentials.

This is part of a bigger task of trying to use the emulators within the context of a PR. I believe it should be possible to use the firebase functions locally, so that they are callable but they use a real firestore database in the config.

I pretty much want to run as if I'm using:

firebase serve --only functions

Thanks for the clarification @alexpchin. Just to verify, from what I understand you have Firebase Cloud Functions such as an HTTP function. When the function runs, you want to use the same credentials from production as credentials for the Firebase Admin SDK to write data to Cloud Firestore.

Is my understanding here correct, or am I missing anything? Would you be able to share a sample code snippet of your function?

Hey @alexpchin - this message function ignored because the firestore emulator does not exist or is not running. will be shown when the Functions emulator skips over a Firestore triggered function. If you have HTTP or callable functions, they are still running.
