Package Exports

passport-geoaxis-oauth20

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (passport-geoaxis-oauth20) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

passport-geoaxis-oauth20

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

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

Install

$ npm install passport-geoaxis-oauth20

Usage

Create an Application

Before using passport-geoaxis-oauth20, you must register an application with GEOAxIS. 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 GEOAxIS authentication strategy authenticates users using a GEOAxIS 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 GEOAxIS profile. The verify callback must call cb providing a user to complete authentication.

var GeoaxisStrategy = require('passport-geoaxis-oauth20').Strategy;

passport.use(new GeoaxisStrategy({
    clientID: GEOAXIS_CLIENT_ID,
    clientSecret: GEOAXIS_CLIENT_SECRET,
    callbackURL: "http://www.example.com/auth/geoaxis/callback"
  },
  function(accessToken, refreshToken, profile, cb) {
    User.findOrCreate({ geoaxisId: profile._json.uid }, function (err, user) {
      return cb(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/auth/geoaxis',
  passport.authenticate('geoaxis', { scope: ['profile'] }));

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