Node server without framework

Introduction

Though Node has many framework to help you getting your server up and running, mainly:

  • Express: The most used framework
  • Total: The ALL-IN-ONE UNITY framework, that have everything and do not depend on any other framework or module.

But, there is always no one size fits all, so developer may need to build his/her own server, without any other dependancy.

Example

Below is a simple quick static file nodejs server:

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

http.createServer(function (request, response) {
    console.log('request ', request.url);

    var filePath = '.' + request.url;
    if (filePath == './')
        filePath = './index.html';

    var extname = String(path.extname(filePath)).toLowerCase();
    var contentType = 'text/html';
    var mimeTypes = {
        '.html': 'text/html',
        '.js': 'text/javascript',
        '.css': 'text/css',
        '.json': 'application/json',
        '.png': 'image/png',
        '.jpg': 'image/jpg',
        '.gif': 'image/gif',
        '.wav': 'audio/wav',
        '.mp4': 'video/mp4',
        '.woff': 'application/font-woff',
        '.ttf': 'applilcation/font-ttf',
        '.eot': 'application/vnd.ms-fontobject',
        '.otf': 'application/font-otf',
        '.svg': 'application/image/svg+xml'
    };

    contentType = mimeTypes[extname] || 'application/octect-stream';

    fs.readFile(filePath, function(error, content) {
        if (error) {
            if(error.code == 'ENOENT'){
                fs.readFile('./404.html', function(error, content) {
                    response.writeHead(200, { 'Content-Type': contentType });
                    response.end(content, 'utf-8');
                });
            }
            else {
                response.writeHead(500);
                response.end('Sorry, check with the site admin for error: '+error.code+' ..\n');
                response.end();
            }
        }
        else {
            response.writeHead(200, { 'Content-Type': contentType });
            response.end(content, 'utf-8');
        }
    });

}).listen(8125);
console.log('Server running at http://127.0.0.1:8125/');
