NodeJS

Favorite Node.js program. Opens your sever directory for loading pages by filename

var http = require('http');

var fs = require('fs');

http.createServer(function(req, res) {

// The filename is simple the local directory and tacks on the requested url

var filename = __dirname+req.url;

// This line opens the file as a readable stream

var readStream = fs.createReadStream(filename);

// This will wait until we know the readable stream is actually valid before piping

readStream.on('open', function () {

// This just pipes the read stream to the response object (which goes to the client)

readStream.pipe(res);

});

// This catches any errors that happen while creating the readable stream (usually invalid names)

readStream.on('error', function(err) {

// res.end(err);

console.log(err);

});

}).listen(8081);
