Art of Programming

Everyone is talking about node.js but another new kid in town is vert.x which is similar in nature to node (talking in terms of javascript server side programming). So today we will write Hello World in vertx.    Steps ::  Click  here  to download vertx or go to vertx home page here Create environment variable VERTX_HOME with value as extracted vertx directory Add %VERTX_HOME%\bin to %PATH% Now you are ready to code. Here is the code load('vertx.js') //Configure Vertx server to listen on port 8080 for incoming http requests vertx.createHttpServer().requestHandler(function(req) {   req.response.end("<html><body><h1>Hello from vert.x!</h1></body></html>"); }).listen(8080, 'localhost'); stdout.println("Server is running on " + "http://127.0.0.1:8080"); Save above code as server-helloworld.js Start node server as >vertx  run server-helloworld.js Server is running o...

In last post   we start with node on windows and create a simple console based "Hello World" program in node. But node is designed to serve on HTTP protocol so today we will write our 1st server side node program. Here is the code //Load http module required for http protocol communications var http = require('http'); //Configure http server to respond all request with Hello World From Node Server var server = http.createServer(function (request, response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.end("Hello World From Node Server\n"); }); // Listen on port 8080, IP defaults to 127.0.0.1 server.listen(8080); // Put a friendly message on the terminal console.log("Server running at http://127.0.0.1:8080/"); Save above code as server-helloworld.js Start node server as >node server-helloworld.js Server running at http://127.0.0.1:8080/ Now go to http://127.0.0.1:8080/  ...
