Colyseus + Firebase Auth Demo

Quick code references:

• Setting-up 'firebase-admin' on the server (server/src/rooms/MyRoom.ts)
• Providing Firebase's accessToken from client-side to the server-side (client/src/index.js)
• Verifying token provided by client on the server-side (server/src/rooms/MyRoom.ts)
• Accessing authenticated user's data on the server-side (server/src/rooms/MyRoom.ts)

Requirements

• Create a Firebase App
• Add "Anonymous" and "Email/Password" as Authentication providers on Firebase:
  • Firebase Console > Authentication > Sign-in method > Anonymous > Enable
  • Firebase Console > Authentication > Sign-in method > Email/Password > Enable
• Configure both client and server with the Firebase App credentials, as documented below

Client-side

Replace the firebaseConfig from client/src/firebase.js with your Firebase app's credentials.

Starting the client:

npm install
npm start

Server-side

(We are following the "Initialize the SDK in non-Google environments" documentation here.)

Add your service-account-file.json file to the server/ folder.

You can get this file from the "Firebase Console" > "Project Settings" > "Service Accounts" > "Generate New Private Key".

Starting the server:

npm install
npm start
