passport-identityua

Passport strategy for authenticating with IdentityUA using the OAuth 1.0a API.

This module lets you authenticate using Universal User from University of Aveiro (UA) in your Node.js applications.

Install

$ npm install @antoniojps/passport-identityua

Usage

Configure Strategy

The IdentityUA authentication strategy authenticates users using a Universal User UA account and OAuth tokens. The strategy requires a verify callback, which receives the access token and corresponding secret as arguments, as well as profile which contains the authenticated user's UA profile. The verify callback must call done providing a user to complete authentication.

In order to identify your application to IdentityUA, specify the consumer key, consumer secret, callback URL and scope within options. The consumer key and secret are obtained by creating an application at IdentityUA site.

passport.use(
  new IdentityUaStrategy(
    {
      consumerKey: IDENTITYUA_CONSUMER_KEY,
      consumerSecret: IDENTITYUA_CONSUMER_SECRET,
      callbackURL: "http://127.0.0.1:3000/auth/ua/callback"
    },
    function(token, tokenSecret, profile, done) {
      User.findOrCreate({ id: profile.id }, function(err, user) {
        return done(err, user);
      });
    }
  )
);

When the scope option is undefined it defaults to uu (Utilizador universal) which returns the user's email.

Scopes

The following example demonstrastes the usage of scopes.

passport.use(
  new IdentityUaStrategy(
    {
      consumerKey: IDENTITYUA_CONSUMER_KEY,
      consumerSecret: IDENTITYUA_CONSUMER_SECRET,
      callbackURL: "http://127.0.0.1:3000/auth/ua/callback",
      scope: ["uu", "name"]
    },
    function(token, tokenSecret, profile, done) {
      User.findOrCreate({ id: profile.id }, function(err, user) {
        return done(err, user);
      });
    }
  )
);

Read the OAuth service documentation under the Serviços Disponíveis section to check all the available scopes.

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get("/auth/ua", passport.authenticate("identityua"));

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

Tests

$ npm install
$ npm test

TODO

Fix scope bug
Fix "Strategy parsing error from access token endpoint parsing error should error" test (it's hardcoded to pass)
