install

npm install sociallogin

setup

// Initialise package
var sociallogin = require('sociallogin');

// Add Strategies function call
sociallogin.addPassportStategies(passportModule, config, userAuthenticationCallback, siteUrl);
* passportModule - an instance of the passportJS module
* config - a json object that holds the configured providers and their credentials
The following will only activate the windowslive, wordpress and yahoo providers for your application
windowslive: {
    clientID: 'XXXXXXXXXXXXXXXXXXXXX',
    clientSecret: 'XXXXXXXXXXXXXXXXXXXXX'
},
wordpress: {
    clientID: 'XXXXXXXXXXXXXXXXXXXXX',
    clientSecret: 'XXXXXXXXXXXXXXXXXXXXX'
},
yahoo: {
    clientID: 'XXXXXXXXXXXXXXXXXXXXX--',
    clientSecret: 'XXXXXXXXXXXXXXXXXXXXX'
}
* userAuthenticationCallback(providerId,providerName,displayName,emailAddress,username,passportDone) - callback function that gives user information to register or login a user . Implement your own based on the user needed for your application.
// providerId - the unique identifier based on the oauth provider
// providerName - the provider name based on the above list e.g google
// displayName - display name from the provider (might be undefined)
// emailAddress - email address from the provider (might be undefined)
// username - username from the provider (might be undefined)
// passportDone(err,user) - passportJS function that you need to call when the user is created or when an error occured
e.g
function addUser(providerId,providerName,displayName,emailAddress,username,passportDone){
      User.findOne({
          'providerId': providerId,
          'providerName': providerName
      }, function(err, user) {
          if (err) {
              return passportDone(err);
          }
          if (!user) {
              user = new User({
                  name: displayName,
                  username: username || emailAddress.split('@')[0],
                  providerName: providerName,
                  providerId: providerId,
                  email: emailAddress,
                  roles: ['authenticated']
              });
              user.save(function(err) {
                  if (err) console.log(err);
                  return passportDone(err, user);
              });
          } else {
              return passportDone(err, user);
          }
      });
  }
* siteUrl - the website url and protocol (https is recomended) that uses this plugin e.g https://sociallogin.heroku.com

// Add authentication urls
sociallogin.addAuthenticationUrls(passportModule, expressModule,signInController, authenticationController, failureRedirectUrl, config);
* passportModule - an instance of the passportJS module
* expressModule - an instance of the express app
* signInController(req,res) - check if user is authenticated and redirect
e.g
function(req, res) {
  if (req.isAuthenticated()) {
    return res.redirect('/');
  }
  res.redirect('#!/login');
};
* authenticationController(req,res) - authenticated user callback
function(req, res) {
  res.redirect('/');
};
* failureRedirectUrl - url to redirect to if authentication fails
e.g '#!/login'
* config - a json object that holds the configured providers and their credentials. Same as above

// Add urls for provider specific authentication to your views. All the configured providers will be accessible with your applicationUrl/oauth/providerName
e.g
<a href="/auth/yahoo" class="button">
    <span>Log In With Yahoo</span>
</a>
