How WebSockets Work (Deep Dive)
· 5 min read
WebSockets are often described as “a persistent connection between client and server”, but that definition hides most of the complexity and the real power behind the protocol.
In this How WebSockets Work deep dive, I want to go beyond surface level explanations and break down what actually happens at the protocol, infrastructure, and architectural level. This perspective comes from building Ressonance, an open source WebSocket as a Service platform, and seeing firsthand where teams struggle when moving from request based systems to real time communication.
If you are building dashboards, notifications, collaborative tools, or any system that depends on real time communication, understanding how WebSockets really work is not optional.
