In Detail

Node.js is simply a tool that lets you useJavaScript on the server side. But it actually does much more than that – by extending JavaScript it allows for a much more integrated and efficient approach to development. It's no surprise that it's a fundamental tool for full-stack JavaScript developers. Whether your working on the back end or front end – by using Node.js you're adopting a much more collaborative and agile way of working – so you and your team can focus on delivering a quality end product. This will ensure you're ready to take on any new challenges that get thrown at you.

NodeJS Essentials takes you through the fundamentals of Node.JS and demonstrates how Node.js can transform the way you work with JavaScript and take greater control over your code.

You will also learn how to create a HTTP server from scratch, route requests, create a RESTful interface, and authenticate users. You will also learn to debug applications using Node.Inspector and the importance of logging, as well as creating a reusable library.Finally, you'll find out how to test and optimizr your code when working with Node.js using the Mocha framework. Follow each step and discover how to test both synchronous and asynchronous code using Mocha unit tests.

With Node.js Essentials you'll find everything you need to create a complete full-stack application with Node.js. It will help you harness JavaScript much more effectively – and in doing so expand your confidence and capabilities as a developer.

Style and approach

This concise guide will help you get up and running with Node.js. Packed with easy to followexamples, you'll be be able to build a complete full-stack application utilizing Node's capabilities.
