passport-mymlh

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

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

Install

$ npm install passport-mymlh

Usage

Create an Application

Before using passport-mymlh, you must register an application with MyMLH. If you have not already done so, a new application can be created at developer applications within MyMLH's My Apps panel. 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 MyMLH authentication strategy authenticates users using a MyMLH 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 MyMLH profile. The verify callback must call cb providing a user to complete authentication.

var MyMLHStrategy = require('passport-mymlh').Strategy;

passport.use(new MyMLHStrategy({
    clientID: MYMLH_CLIENT_ID,
    clientSecret: MYMLH_SECRET,
    callbackURL: "http://localhost:8080/callback/mymlh"
  },
  function(accessToken, refreshToken, profile, cb) {
    User.findOrCreate({ mymlhId: profile.id }, function (err, user) {
      return cb(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

// In my example this is equivalent to '/register' route
app.get('/auth/mymlh',
  passport.authenticate('mymlh'));

// In my example this is equivalent to '/callback/mymlh' route
app.get('/auth/mymlh/callback',
  passport.authenticate('mymlh', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect('/');
  });

Examples

Developers using Express can look at this example. This tutorial provides many ways to authenticate users using passport with different strategies including local, Google, Facebook, and Twitter. It's a great starting point for developing web applications.
