#!/usr/bin/env bash
node -e 'var http = require("http"); var fs = require("fs"); process.stdin.resume(); process.stdin.setEncoding("utf8"); var data = ""; process.stdin.on("data", function(buf) { data += buf; }); process.stdin.on("end", function() { http.createServer(function (request, response) { response.writeHead(200); response.write(data); response.end(); }).listen(8989); });'

Add the snippet in your .bashrc
