passport-oneauth

Passport strategy for authenticating with OneAuth using the OAuth 2.0 API.

This module lets you authenticate using coding-blocks's Oneauth server in your Node.js applications. By plugging into Passport, Oneauth authentication can be integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-oneauth

Usage

Create an Application

Before using passport-oneauth, you must register an application with Coding Blocks. If you have not already done so, a new application can be created at [developer applications](https://account.codingblocks.com/clients/add .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 callback URL which matches the route in your application.

Configure Strategy

The Oneauth authentication strategy authenticates users using a coding-blocks 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 OneauthStrategy = require('passport-oneauth').Strategy;

passport.use(new OneauthStrategy({
    clientID: ONEAUTH_CLIENT_ID,
    clientSecret: ONEAUTH_CLIENT_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/oneauth/callback"
  },
  function(accessToken, refreshToken, profile, cb) {
    User.findOrCreate({ oneauthId: profile.id }, function (err, user) {
      return cb(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/auth/oneauth',
  passport.authenticate('oneauth'));

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

Examples

Developers using the popular Express web framework can refer to an example as a starting point for their own web applications. The example shows how to authenticate users using Facebook. However, because both Facebook and Oneauth use OAuth 2.0, the code is similar. Simply replace references to Facebook with corresponding references to Oneauth.
