HTTP's request-response pattern has served us well, but modern web applications demand more. Real-time communication demands different protocols, yet maintaining testability and simplicity remains crucial to developer experience.

In this talk, we'll explore how http4k extends HTTP's capabilities through WebSocket and Server-Sent Events support and how these protocols can be modelled as simple functions, making them as testable as plain HTTP endpoints. We'll then show how these streaming capabilities open up new possibilities for server-side rendering, bringing us full circle from the days of JSP to modern reactive interfaces - all while keeping the complexity on the server where it belongs.

Join us to discover how http4k's streaming capabilities can enhance your web applications, enabling everything from chat applications to live dashboards and reactive server-rendered interfaces.
