Implement Frontend Web-Socket

[antonplagemann]

As a developer
I want to have a websocket class in the frontend
so that I can receive events e.g. music stopped) from the backend in real time.

Description:

Implement a web socket class in the frontend. Check if this can be realized using Opine (see client examples). If not, check if it can be done the native browser api. Use a separate file for your implementation.

🟢 In scope:

• Implement a Socket class that creates a new web socket, opens a backend connection. and can be imported by other modules for registering callback listening functions.
• Add/test functionality to receive messages and pass them to the caller (no modification here)
• Create default listeners for open, close, etc.

🔴 Not in scope:

• Backend implementation of the web socket
• Web socket documentation

What should be the result?

A working web socket implementation in the frontend.
