Explore the inner workings of the Netty framework and WebSockets implementation in this 38-minute conference talk from Devoxx Poland 2024. Dive deep into how popular tools and frameworks are constructed by examining Netty, an asynchronous event-driven network application framework, and its relationship with WebSockets technology. Learn about WebSockets as an alternative communication method built on TCP protocol that enables two-way, full-duplex communication between clients and servers. Discover how to implement WebSocket solutions using Netty's efficient, event-based architecture while understanding the framework's core conventions and design patterns. Gain practical insights into building high-performance network applications and understand the underlying mechanisms that power modern web communication protocols.
