How We Built Our In-house Chat Platform for the Web

This post details the technical implementation of an in-house chat platform for the web, focusing on the challenges of handling multiple browser tabs and maintaining a single TCP connection. It introduces the use of JavaScript's SharedWorker and BroadcastChannel APIs to manage state synchronization across tabs and abstract the underlying transport mechanism. The architecture involves a TCP gateway for mobile apps and a hybrid approach for the web using SharedWorker to manage connections and BroadcastChannel for inter-tab communication, ensuring a seamless user experience.
