Data Push Apps with HTML5 SSE

Data Push Apps with HTML5 SSE: Pragmatic solutions for real-world clients

HTML5 Server Side Events (SSE) allow the server to push new data to clients, providing a superior solution to having the client poll for new data every few seconds. Presently 60% of desktop and mobile browsers support it, but this book will show how to develop fallback solutions supporting 99%. SSE offers rapid updates with low latency, and is much simpler to implement than the complementary websockets approach. For many applications, SSE will provide a cleaner implementation more rapidly.
