Node.js is the new buzz in town and has a vibrant community.It ships with npm, which is a tool that helps automate various development, deployment, and installation of node modules, and makes the process much easier. Instant Node Package Module is a practical guide to authoring and distributing node modules, and also for creating and managing private, standalone node.js projects. Starting with getting node.js installed and running on a variety of platforms, we then proceed to learn about code modularization and achieving it in node.js. Picking up a practical example, we will then explore the whole process and life cycle of conceiving, writing, and publishing a node module. We will also learn how to exploit a toolsincluded with npm to automate various development and deployment steps. Later on, we will discover the power of npm and how its different features and configurations can save large amounts of time by providing a helping hand for automating repetitive tasks between writing and publishing your modules.
