This book introduces you to Node, the new web development framework written in JavaScript. Youll learn hands-on how Node makes life easier for experienced JavaScript developers: not only can you work on the front end and back end in the same language, youll also have more flexibility in choosing how to divide application logic between client and server. Written by a core contributor to the framework, Node: Up and Running shows you how Node scales up to support large numbers of simultaneous connections across multiple servers, and scales down to let you create quick one-off applications with minimal infrastructure.
