server.js

var http = require('http');
var fs = require('fs');

function startServer() {
    var onRequest = function(request, response) {
        console.log('Request received');
        response.writeHead(200, { 'Content-Type': 'text/html' });
        var myReadStream = fs.createReadStream(__dirname + '/index.html', 'utf8');
        // response.write('Hello from out application');
        myReadStream.pipe(response);
    }

    var server = http.createServer(onRequest);

    server.listen(3000, '127.0.0.1');
    console.log('Server started on localhost port 3000');
}

exports.startServer = startServer;

app.js

var server = require('./server');

server.startServer();

exports.startServer = startServer; 这里为什么又不需要添加model（module.exports）了呢？

exports.startServer = startServer;
等同于
module.exports.startServer = startServer;

为什么terminal会出现：

throw er; // Unhandled 'error' event
