You can use node web server, setup with express. It is quite easy to setup, then expose a simple API from the express server and use HttpClient from Angular to call the API.

https://expressjs.com/

If you want it more real time, based on the event, you can even use socket.io with node express server.

You can use socket.io even on client side, so the it allow real time communication.
