Handling Websocket Drops and Disconnections

WebSocket is a computer communications protocol providing full-duplex communication channels over a single TCP connection. That being said, Websockets are fragile because they can get disconnected by internet stability, technical limitations, potential bugs, etc.

Best practices for Websockets:

1. Implement a ping-pong mechanism to check if the socket to the server is still up and healthy
2. Auto reconnect whenever the connection ends
3. Monitor the network stability of the host you're running your app from

Web3JS has the ping-pong and auto-reconnect feature build-in that you can find here https://web3js.readthedocs.io/en/v1.7.5/include_package-core.html?highlight=websocket#configuration

If you want to implement it yourself but need a code reference, you can go here https://github.com/ethers-io/ethers.js/issues/1053#issuecomment-808736570
