Your First Week With Node.js

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.

In this book, we'll offer a beginner's introduction to Node and its related technologies, and get you under way writing your first Node applications.

It contains:

  • What Is Node and When Should I Use It? by James Hibbard
  • A Beginner Splurge in Node.js by Camilo Reyes and Michiel Mulders
  • A Beginner's Guide to npm- the Node Package Manager by Michael Wanyoike and Peter Dierx
  • Forms, File Uploads and Security with Node.js and Express by Mark Brown
  • MEAN Stack: Build an App with Angular 2+ and the Angular CLI by Manjunath M
  • Debugging JavaScript with the Node Debugger by Camilo Reyes
  • Using MySQL with Node.js and the mysql JavaScript Client by Jay Raj
  • How to Use SSL/TLS with Node.js by Florian Rappl and Almir Bijedic

This book is for anyone who wants to start learning server-side development with Node.js. Familiarity with JavaScript is assumed, but we don't assume any previous back-end development experience.
