https://github.com/amachang/facebook-node-sdk decided to use this module to build my facebook integrated login for node.js following the example with express:
var express = require('express');
var Facebook = require('facebook-node-sdk');
var app = express.createServer();
app.configure(function () {
app.use(express.bodyParser());
app.use(express.cookieParser());
app.use(express.session({ secret: 'foo bar' }));
app.use(Facebook.middleware({ appId: 'YOUR_APP_ID', secret: 'YOUR_APP_SECRET' }));
});
app.get('/', Facebook.loginRequired(), function (req, res) {
req.facebook.api('/me', function(err, user) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello, ' + user.name + '!');
});
});
how to add additional permissions like "email"?
Take a look at the method getLoginUrl in the Facebook Node SDK. You can provide a scope parameter here to specify the email permission. See Permissions for a list of available permissions.
hmm You don't need to edit this file :) all you have to do is add scope to your config, like this:
app.use(Facebook.middleware({ appId: 'YOUR_APP_ID', secret: 'YOUR_APP_SECRET', scope 'YOUR_SCOPE' }))
this config is then passed to getLoginUrl function
app.get('/', Facebook.loginRequired({scope: 'email'}), function (req, res) {
/*-----*/
});
