It prints the words "Hello World" to the terminal.You can run this by putting it in a file called "hello-console.js" and running it with I'd guess that while it's not the only use case for node.JS, most people are using it as a web application platform. Design by // Configure our HTTP server to respond with Hello World to all requests.// Creates a new TCP server.

My first node framework is In order to test this, you will need to install the I'll install the following libraries that are common to my projects:You can install these however you please, but here is how I'd do it. Beispiel “Hello World” Dies ist wohl die einfachste Express-Anwendung, die Sie erstellen können. In this example we'll create an HTTP server listening on port 1337, which sends Hello, World! This article will go through a few simple hello world type examples with everything from simple terminal output to an http server that uses an external framework for some semantic sugar. First, install Node.js for your platform.
It will start a web server on specified port and host.For example, above script started a web server on port 3000.
Example.

We’ll keep the amount of browser-specific commands (like alert) to a minimum so that you don’t spend time on them if you plan to concentrate on another environment (like Node.js). This makes node quick, nimble, and easy to maintain, but is usually not enough to get started on a real world application.
