Introduction to OAuth with Node.js

Save hours of frustration spent in painful online search while working on OAuth with Node.js... and especially Twitter API.

A typical modern web application has to communicate with other services, even if it’s your own service or application. This is usually done via an open standard for authorization, or OAuth. Therefore, your ability to easily and skillfully use OAuth in your work is paramount!
There are standards, specifications, and fancy diagrams, and it is certainly useful to read them as a first step. However, developers often need hands-on experience to acquire the full understanding and confidence necessary to execute this critical task (i.e., use OAuth) efficiently and correctly.
Introduction to OAuth in Node.js is a concise practical book designed to help you to get started with OAuth 1.0, 2.0, and Echo, and to implement a Sign in with Node.js using Twitter API (and ideally any other) authentication. Who has time to read thick and complex books anyway? So this is your mini-book!
In this mini-book, we’ll explore the three main authentication methods utilizing minimalistic oauth module to explain the basics, and then use extensive everyauth with an Express.js app. The last but not least, is OAuth 2.0 server implementation with oauth2-server. So the chapters of the book are organized in the following order: OAuth 1.0 one-legged OAuth 2.0 one-legged OAuth Echo OAuth 1.0 Sign in with Everyauth and Express.js (three-legged OAuth 1.0) OAuth 2.0 Server and Client
