Book Description

While there have been quite a few attempts to get JavaScript working as a server-side language, Node.js (frequently just called Node) has been the first environment that's gained any traction. It's now used by companies such as Netflix, Uber and Paypal to power their web apps. Node allows for blazingly fast performance; thanks to its event loop model, common tasks like network connection and database I/O can be executed very quickly indeed.

From a beginner's point of view, one of Node's obvious advantages is that it uses JavaScript, a ubiquitous language that many developers are comfortable with. If you can write JavaScript for the client-side, writing server-side applications with Node should not be too much of a stretch for you.

This book offers aselection of beginner-level tutorials to privide you with an introduction to Node and its related technologies, and get you under way writing your first Node applications. It contains:

  1. What Is Node and When Should I Use It?
  2. Build a Simple Page Counter Service with Node.js
  3. Understanding module.exports and exports in Node.js
  4. Forms, File Uploads and Security with Node.js and Express
  5. Working with Databases in Node
  6. How to Build and Structure a Node.js MVC Application
  7. Local Authentication Using Passport in Node.js
  8. How to Debug a Node App
