meteor add rocketchat:oauth2-server

Implementation

Server implementation

• Initialize the lib
• Add routes to the default router
• Implement an authenticated route

server/oauth2server.js

var oauth2server = new OAuth2Server({
  // You can change the collection names, the values
  // below are the default values.
  accessTokensCollectionName: 'oauth_access_tokens',
  refreshTokensCollectionName: 'oauth_refresh_tokens',
  clientsCollectionName: 'oauth_clients',
  authCodesCollectionName: 'oauth_auth_codes',
  // You can pass the collection object too
  // accessTokensCollection: new Meteor.Collection('custom_oauth_access_tokens'),
  // refreshTokensCollection: new Meteor.Collection('custom_oauth_refresh_tokens'),
  // clientsCollection: new Meteor.Collection('custom_oauth_clients'),
  // authCodesCollection: new Meteor.Collection('custom_oauth_auth_codes'),
  // You can enable some logs too
  debug: true
});

// Add the express routes of OAuth before the Meteor routes
WebApp.rawConnectHandlers.use(oauth2server.app);

// Add a route to return account information
oauth2server.routes.get('/account', oauth2server.oauth.authorise(), function(req, res, next) {
  var user = Meteor.users.findOne(req.user.id);

  res.send({
    id: user._id,
    name: user.name
  });
});

Client/Pupup implementation

client/authorize.js

// Define the route to render the popup view
FlowRouter.route('/oauth/authorize', {
  action: function(params, queryParams) {
    BlazeLayout.render('authorize', queryParams);
  }
});

// Subscribe the list of already authorized clients
// to auto accept
Template.authorize.onCreated(function() {
  this.subscribe('authorizedOAuth');
});

// Get the login token to pass to oauth
// This is the best way to identify the logged user
Template.authorize.helpers({
  getToken: function() {
    return localStorage.getItem('Meteor.loginToken');
  }
});

// Auto click the submit/accept button if user already
// accepted this client
Template.authorize.onRendered(function() {
  var data = this.data;
  this.autorun(function(c) {
    var user = Meteor.user();
    if (user && user.oauth && user.oauth.authorizedClients && user.oauth.authorizedClients.indexOf(data.client_id()) > -1) {
      c.stop();
      $('button').click();
    }
  });
});
