passport-praisecharts

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

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

Install

$ npm install passport-praisecharts

Usage

Create an Application

Before using passport-praisecharts, you must register an application with PraiseCharts. If you have not already done so, a new application can be created at PraiseCharts Application Management. Your application will be issued a consumer key (API Key) and consumer secret (API 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 PraiseCharts authentication strategy authenticates users using a PraiseCharts account and OAuth tokens. The consumer key and consumer 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 corresponding secret as arguments, as well as profile which contains the authenticated user's PraiseCharts profile. The verify callback must call cb providing a user to complete authentication.

passport.use(new PraiseChartsStrategy({
    consumerKey: TWITTER_CONSUMER_KEY,
    consumerSecret: TWITTER_CONSUMER_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/praisecharts/callback"
  },
  function(token, tokenSecret, profile, cb) {
    User.findOrCreate({ praisechartsId: profile.id }, function (err, user) {
      return cb(err, user);
    });
  }
));

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/auth/praisecharts',
  passport.authenticate('praisecharts'));

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

Examples

Developers using the popular Express web framework can refer to an example as a starting point for their own web applications.
