cas

Central Authentication Service (CAS) client for Node.js

This module only handles the ticket validation step of the CAS login process. Planned features include functions to generate the login/logout URLs.

Generally, to start the login process, send your users to: https://cas_base_url/login?service=url_to_handle_ticket_validation. In the University of Waterloo example below, this url would be: https://cas.uwaterloo.ca/cas/login?service='my_service'.

Installation

via npm:

$ npm install cas

Usage

Setup:

var CAS = require('cas');
var cas = new CAS({base_url: 'https://cas.uwaterloo.ca/cas', service: 'my_service'});

Using it in a login route:

exports.cas_login = function(req, res) {
  var ticket = req.param('ticket');
  if (ticket) {
    cas.validate(ticket, function(err, status, username) {
      if (err) {
        // Handle the error
        res.send({error: err});
      } else {
        // Log the user in
        res.send({status: status, username: username});
      }
    });
  } else {
    res.redirect('/');
  }
};
