Discussion on: Building a realtime multiplayer browser game in less than a day - Part 3/4

Hey - yes. So the front end client doesn't use a key directly, it uses a token (which is why you see an authUrl). As for the backend server, it uses the API directly via the env variables. Your .env file at the root of the project would look as follows:

ABLY_API_KEY=yourapikeyvalue
PORT=5000

This can be accessed from the code as follows:

const envConfig = require("dotenv").config();
const ABLY_API_KEY = process.env.ABLY_API_KEY;
