passport-globus

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

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

This module was forked from the passport-orcid package which is copyrighted under an MIT License.

Install

$ npm install passport-globus

Usage

Create an Application

Before using passport-globus, you must register an application with Globus. If you have not already done so, a new project can be created using Globus's Developer Tools. 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 Globus authentication strategy authenticates users using a Globus 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 params which contains the authenticated user's Globus identifier and name. The verify callback must call done providing a user to complete authentication.

var jwt = require('jsonwebtoken')
var GlobusStrategy = require('passport-globus').Strategy;

passport.use(new GlobusStrategy({
    clientID: GLOBUS_CLIENT_ID,
    clientSecret: GLOBUS_CLIENT_SECRET,
    callbackURL: "http://www.example.com/auth/globus/callback"
  },
  function(accessToken, refreshToken, params, profile, done) {
    // NOTE: `profile` is empty, use `params` instead
    User.findOrCreate(jwt.decode(params.id_token), function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

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

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

Example

Developers using the popular Express web framework can refer to an example as a starting point for their own web applications.
