Http echo service written in Node.js

I have added a small repo on Github that shows how to create a simple HTTP echo service. https://github.com/toreaurstadboss/NodeJsHttpEchoServer The server.js is script is this:
let http = require('http');

console.log('Attempting to start the Node.js echos server on port 8081..')
http.createServer().on('request', function(request, response){
 request.pipe(response);
}).on('close', function(){
    console.log('The Node.js echo server has been closed.')
})
.listen(8081);

console.log('Node.js echo server started on port 8081.')

This will pipe out the requesting data to the response. Test it out with this command for example in a command window: curl -d "Hello dog" http://localhost:8081 Note - use not Powershell for this command as Powershell has aliased curl command for Invoke-WebRequest. Rather install curl with Chocolatey for example, choco install curl
