passport-github-oauth20

Passport strategy for authenticating with GitHub using the OAuth 2.0 API. This package is heavily based on passport-google-oauth20 package

This module lets you authenticate using GitHub in your Node.js applications. By plugging into Passport, GitHub authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-github-oauth20

Usage

Create an Application

Before using passport-github-oauth20, you must register an application with GitHub. If you have not already done so, a oauth app has to be created in Developers settings. Your application will be issued a client ID and client secret, which need to be provided to the strategy. You will also need to configure a redirect URI which matches the route in your application.

Configure Strategy

The GitHub authentication strategy authenticates users using a GitHub account and OAuth 2.0 tokens. The client ID and secret obtained when creating an application are supplied as options when creating the strategy. The strategy also requires a verify callback, which receives the access token and optional refresh token, as well as profile which contains the authenticated user's GitHub profile. The verify callback must call cb providing a user to complete authentication.

var GitHubStrategy = require("passport-github-oauth20").Strategy;

passport.use(
  new GitHubStrategy(
    {
      clientID: GITHUB_CLIENT_ID,
      clientSecret: GITHUB_CLIENT_SECRET,
      callbackURL: "http://www.example.com/auth/github/callback",
    },
    function (accessToken, refreshToken, profile, cb) {
      User.findOrCreate({ githubId: profile.id }, function (err, user) {
        return cb(err, user);
      });
    }
  )
);

Authenticate Requests

Use passport.authenticate(), specifying the 'github' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get(
  "/auth/github",
  passport.authenticate("github", { scope: ["user"] })
);

app.get(
  "/auth/github/callback",
  passport.authenticate("github", { failureRedirect: "/login" }),
  function (req, res) {
    // Successful authentication, redirect home.
    res.redirect("/");
  }
);
