var express = require('express'); var app = express(); app.get('/', function(req, res){ res.send('hello world'); }); app.listen(1337); console.log('Server running at http://127.0.0.1:1337/'); var favicon = require('serve-favicon'); app.use(favicon(__dirname + '/favicon.ico')); var fs = require('fs') var logger = require('morgan'); var accessLogStream = fs.createWriteStream(__dirname + '/access.log', {flags: 'a'}); app.use(logger('combined', {stream: accessLogStream}));
