Bot to interact with existing websocket server

I need a bot to interact with a pre-existing socket.io server. I require this bot to be able to listen to messages exchanged in the websocket connection, as well as send messages in the highest speed possible if a certain type of messages pops up. The bot is meant for sniping deals on a website that utilizes websocket for it’s market listings, and executing a buy order happens through this websocket connection. The code for the bot must be extremely optimized and the lowest latency possible, I dont require any gui, just control over detection of JSON parameters I will later specify. The bot must be written in a fast language, be it C++, Rust, Golang or Node.JS
