Passport-Tequila

Passport strategy for authenticating with Tequila.

This module lets you authenticate and controll access using Tequila in your Node.js applications that use a Connect-style middleware, including Express. Plain old Node.js servers will also be supported at some point in the future (but don't work right now).

Installation

$ npm install passport-tequila

Usage

Example Code

See the express and passport demo app for a working example (requires a Tequila server in your domain, which means it is most likely to work from inside EPFL).

Configuring the Strategy

var tequila = require('passport-tequila');
var myStrategy = new tequila.Strategy({
    service: "The name of my app",  // Appears on Tequila login screen
    request: ["displayname", "firstname"],  // Personal info to fetch
  },
  function(userKey, profile, done) {
    User.findOrCreate(profile, function (err, user) {
      done(err, user);
    });
  }
);
passport.use(myStrategy);

Protecting Routes

Tequila is designed so that Web apps redirect unauthenticated users to the Tequila server, which redirects back to the protected page or resource the user started from.

In a Node.js app, this is achieved by using the 'myStrategy.ensureAuthenticated' function as middleware:

app.get('/private', tequila.ensureAuthenticated, function(req, res){ // .. business as usual });

User Authentication Details

When the user is authenticated (regardless of whether the page they are on uses the tequila.ensureAuthenticated middleware mentioned above), 'req.user' holds the user's identity as fetched from the Tequila server:

 req.user.displayName  // Conforms to http://passportjs.org/guide/profile/
 req.user.tequila.key  // Tequila-specific additions

Note that e.g. 'req.user.displayName' only appears if it was explicitly requested from Tequila (see above, Configuring the Strategy).

Logging Out

To log out the user from this app only:

app.get('/logout', function(req, res){ req.logout(); res.redirect('/'); });

Alternatively, one can also log out from Tequila altogether like this.

app.get('/globallogout', myStrategy.globalLogout("/"));
