Notice that the **mediasoup-demo-server** configuration file has been modified. It’s no longer a CommonJS `config.js` file. Now it’s a ESM `config.mjs` and its location can be set via environment variable.

Please read the new `README` in the `mediasoup-demo/server` folder for full details about how to set it up:
