dev-server.js:
This file sets up an HTTP server that serves static files from a local folder.
It listens on port 8089 and handles GET requests.
If the requested file exists, it is served with the option to inject client-side WebSocket code if it's an HTML file.
If the file or directory doesn't exist, a 404 response is sent.
client-websocket.js:
This file sets up a WebSocket client connection to ws://localhost:8090.
If the WebSocket connection is closed, it attempts to reconnect until it succeeds or exceeds the maximum number of attempts.
Once a reconnection is established, it reloads the webpage using location.reload().
