Passport strategies for authenticating with Yahoo! using the OAuth 1.0a API.

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

$ npm install passport-yahoo-oauth

The Yahoo authentication strategy authenticates users using a Yahoo account and OAuth tokens. The strategy requires a verify callback, which accepts these credentials and calls done providing a user, as well as options specifying a consumer key, consumer secret, and callback URL.

passport.use(new YahooStrategy({
    consumerKey: YAHOO_CONSUMER_KEY,
    consumerSecret: YAHOO_CONSUMER_SECRET,
    callbackURL: "http://127.0.0.1:3000/auth/yahoo/callback"
  },
  function(token, tokenSecret, profile, done) {
    User.findOrCreate({ yahooId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

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

For example, as route middleware in an Express application:

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

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

For a complete, working example, refer to the login example.

If you receive a 401 Unauthorized error, it is most likely because you have not yet specified any application "Permissions". Once you do so, Yahoo! will generate new credentials for usage, and will then authenticate your requests properly.
