Authenticate with the Twitter API using OAuth and Node.js

Simple Twitter Auth

var OAuth2 = require('OAuth').OAuth2;
var https = require('https');

var oauth2 = new OAuth2(KEY, SECRET, 'https://api.twitter.com/', null, 'oauth2/token', null);
oauth2.getOAuthAccessToken('', {
    'grant_type': 'client_credentials'
}, function (e, access_token) {
    console.log(access_token); //string that we can use to authenticate request

    var options = {
        hostname: 'api.twitter.com',
        path: '/1.1/statuses/user_timeline.json?screen_name=mostlyharmlessd',
        headers: {
            Authorization: 'Bearer ' + access_token
        }
    };


    https.get(options, function (result) {
        var buffer = '';
        result.setEncoding('utf8');
        result.on('data', function (data) {
            buffer += data;
        });
        result.on('end', function () {
            var tweets = JSON.parse(buffer);
            console.log(tweets); // the tweets!
        });
    });
});

thanks for this,
I made a coffeescript helper

https = require('https')
http = require('http')
config = require('config.coffee')
OAuth2 = require('OAuth').OAuth2

exports.help =
    oauth2: new OAuth2(config.site.twitter.screenname.key, config.site.twitter.screenname.secret, 'https://api.twitter.com/', null, 'oauth2/token', null)

    securerequest: (options, callback) ->
        request = https.request options, (res)->
            data = []

            res.on 'data', (chunk)->
                data.push(chunk)

            res.on 'error', (e)->
                console.log "Got error: #{e.message}"

            res.on 'end', ()->
                data = JSON.parse data.join('')
                callback(data)
        request.end()

    request: (options, callback) ->
        request = http.request options, (res)->
            data = []

            res.on 'data', (chunk)->
                console.log chunk
                data.push(chunk)

            res.on 'error', (e)->
                console.log "Got error: #{e.message}"

            res.on 'end', ()->
                data = JSON.parse data.join('')
                callback(data)
        request.end()

    oauthtoken: (callback) ->
        oauth2.getOAuthAccessToken '', {'grant_type': 'client_credentials'}, (e, access_token) ->
            callback access_token
