Twitter API request error while using node.js - node.js

Question

I am trying to make a request to the Twitter API and respond with the JSON.
This is my code.
var http = require('http');
var request = require('request');
var url = require('url');
app.get('/twwets/:username', function(req, response) {
var username = req.params.username;
options = {
protocol: "http:",
host: 'api.twitter.com',
pathname: '/1/statuses/user_timeline.json',
query: { screen_name: username, count: 10}
}
var twitterUrl = url.format(options);
request(twitterUrl).pipe(response);
}).listen(8080);
And this is what I get when I run node app.js in my terminal:
module.js:340
throw err;
^
Error: Cannot find module 'require'

I need to know what do I do wrong.
[My code may seem useless, but it's just for educational purposes. Please excuse any mistake.]
EDIT: I still get the same error after I saved and run the code in my shell.

Answer 1

Typo;
var request = require('require');
should most likely be
var request = require('request');
EDIT: You're also missing express, I suspect you'll want to add these lines;
var express = require('express');
var app = express();
...and npm install request express to get the modules installed.
