Firestore emulator auth connection issues

Environment details

• OS: macOS 10.14.2
• Node.js version: 8.15.0
• yarn version: 1.12.3
• @google-cloud/firestore version: 0.19.0
• firestore emulator version: 1.2.2

Description

Hey there! 👋

I’m trying to connect to local firestore emulator for testing, but it seems to have auth issues. I’ve checked @firebase/testing package for a reference, and the only clue I have is token hjacking which I can’t achieve in any possible way I’ve tried with this module.

It there maybe a way to override access token to owner or a way to add custom auth headers I’m missing? Thanks.

Steps to reproduce

1. Run the emulator:

java -Duser.language=en -jar ~/.cache/firebase/emulators/cloud-firestore-emulator-v1.2.2.jar --port 8080 --rules firestore.rules

// firestore.rules
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

1. Connect to it:

const grpc = require('grpc');

const firestore = new Firestore({
  projectId: 'test-lzqnvo3eh', // project id is random for each run
  timestampsInSnapshots: true,
  sslCreds: grpc.credentials.createInsecure(),
  servicePath: 'localhost',
  port: 8080,
  'grpc.initial_reconnect_backoff_ms': 100,
  'grpc.max_reconnect_backoff_ms': 100,
});

1. Run sample operation:

await firestore.doc('foo/bar').set({ value: 42 });

Glad to hear it. There are a few additional features we’ve recently added that I’m hoping prove helpful, and tighter integration with Cloud Functions in the pipeline. Stay tuned 😃

Quick update: firestore-emulator v1.3.0 seems to be working as expected (except datastore methods like .listDocuments()) and looks more or less suitable for testing 🎉
