Take your web development skills from browser to server with Node—and learn how to write fast, highly scalable network applications on this JavaScript-based platform. With this hands-on guide, you’ll quickly master Node’s core fundamentals, gain experience with several built-in and contributed modules, and learn the differences and parallels between client- and server-side programming. Get up to speed on Node’s event-driven, asynchronous I/O model for developing data-intensive applications that are frequently accessed but computationally simple. If you’re comfortable working with JavaScript, this book provides numerous programming and deployment examples to help you take advantage of server-side development with Node.     Explore Node’s unique approach to asynchronous development     Build sample Node applications with the Express framework and Connect middleware     Use NoSQL solutions such as Redis and MongoDB—and explore Node’s relational database modules     Work with PDF files, serve HTML5 media, and create graphics with Canvas     Set up bidirectional communication between browser and server with WebSockets     Learn in-depth practices for debugging and testing your applications     Deploy Node applications in the cloud or on your own system "Learning Node will make it easy for someone from any programming background to get a grip on Node.js and build amazing projects." —Tom Hughes-Croucher, co-author of Node: Up and Running (O’Reilly) About the Author Shelley Powers has been working with, and writing about, web technologies--from the first release of JavaScript to the latest graphics and design tools--for more than 12 years. Her recent O'Reilly books have covered the semantic web, Ajax, JavaScript, and web graphics. She's an avid amateur photographer and web development aficionado, who enjoys applying her latest experiments on her many web sites.
