How to get Firebase Project Name or ID from Cloud Function

Question

I am using Cloud Functions and want to get the project name from within one of my Javascript server files. I know that value is stored in the .firebaserc, but I don't think that file is available on the server, right? I want to do something like this:

const functions = require('firebase-functions'); const admin = require('firebase-admin');  admin.getProjectName();  // or getProjectID() 

or

functions.getProjectName();  

Answer 1

Thank you @Frank. The answer is: process.env.GCLOUD_PROJECT.
I'm not sure where the variable process comes from, but this does work to get the project name.

Answer 2

Firebase admin SDK has access to that information for you.

const admin = require('firebase-admin'); const projectId = admin.instanceId().app.options.projectId
