Data Push Apps With Html5 Sse

Make sure your website or web application users get content updates right now with minimal latency. This concise guide shows you how to push new data from the server to clients with HTML5 Server-Sent Events (SSE), an exceptional technology that doesn’t require constant polling or user interaction. You’ll learn how to build a real-world SSE application from start to finish that solves a demanding domain problem. You’ll also discover how to increase that application’s desktop and mobile browser support from 60% to 99%, using different fallback solutions. If you’re familiar with HTML, HTTP, and basic JavaScript, you’re ready to get started. Determine whether SSE, WebSockets, or data pull is best for your organization Develop a working SSE application complete with backend and frontend solutions Address error handling, system recovery, and other issues to make the application production-quality Explore two fallback solutions for browsers that don’t support SSE Tackle security issues, including authorization and "disallowed origin" Develop realistic, repeatable data that’s useful in test-driven SSE design Learn SSE protocol elements not covered in the example application

HTML5 brings the biggest changes that HTML has seen in years. Web designers and developers now have a whole host of new techniques up their sleeves, from displaying video and audio natively in HTML, to creating realtime graphics directly on a web page without the need for a plugin. But all of these new technologies bring more tags to learn and more avenues for things to go wrong. HTML5 Solutions provides a collection of solutions to all of the most common HTML5 problems. Every solution contains sample code that is production-ready and can be applied to any project.

This book is for programmers who want to learn about real-time communication and utilize the full potential of WebRTC. It is assumed that you have working knowledge of setting up a basic telecom infrastructure as well as basic programming and scripting knowledge.
