NodeJS Library for Facebook
With facebook-node-sdk you can now easily write the same code and share between your server (nodejs) and the client (Facebook Javascript SDK).
Installing facebook-node-sdk
npm install fb
var FB = require('fb');
Graph Api
Get
var FB = require('fb');
FB.api('4', function (res) {
if(!res || res.error) {
console.log(res.error);
return;
}
console.log(res.id);
console.log(res.name);
});Passing Parameters
var FB = require('fb');
FB.api('4', { fields: ['id', 'name'] }, function (res) {
if(!res || res.error) {
console.log(res.error);
return;
}
console.log(res.id);
console.log(res.name);
});Post
var FB = require('fb');
var accessToken = ".....";
var body = 'My first post using facebook-node-sdk';
FB.api('me/feed', 'post', { message: body, access_token: accessToken }, function (res) {
if(!res || res.error) {
console.log(res.error);
return;
}
console.log('Post Id: ' + res.id);
});Delete
var FB = require('fb');
var accessToken = '.....');
var postId = '1234567890';
FB.api(postId, 'delete', { access_token: accessToken }, function (res) {
if(!res || res.error) {
console.log(res.error);
return;
}
console.log('Post was deleted');
});Facebook Query Language (FQL)
Query
var FB = require('fb');
var accessToken = '.....';
FB.api('fql', { q: 'SELECT uid FROM user WHERE uid=me()', access_token: accessToken }, function (res) {
if(!res || res.error) {
console.log(res.error);
return;
}
console.log(res.data);
});Multi-query
var FB = require('fb');
var accessToken = '.....';
FB.api('fql', { q: [
'SELECT uid FROM user WHERE uid=me()',
'SELECT name FROM user WHERE uid=me()'
], access_token: accessToken }, function(res) {
if(!res || res.error) {
console.log(res.error);
return;
}
console.log(res.data[0].fql_result_set);
console.log(res.data[1].fql_result_set);
});Named Multi-query
var FB = require('fb');
var accessToken = '.....';
FB.api('fql', { q : {
id: 'SELECT uid FROM user WHERE uid=me()',
name: 'SELECT name FROM user WHERE uid IN (SELECT uid FROM #id)'
}, access_token: accessToken }, function(res) {
if(!res || res.error) {
console.log(res.error);
return;
