Node.js example scripts


This article lists a few simple Node.js examples you can use to test your installation.

Is it possible to run Node.js on ports 80 or 443?

While it's not possible to assign your app to use ports 80 or 443, you can configure a Proxy Server in the DreamHost panel. This allows your app to use a non-privileged port in combination with your SSL certificate. View the following article for further details:

Test if node is working

Create and run this script within your terminal to determine if Node.js was installed correctly.

  1. Create a file named helloworld.js with the following line:
    console.log('Hello World!');
  2. Run the script using the node command.
    [server]$ node HelloWorld.js
    Hello World!

    If Node.js is correctly installed, you will see the console respond with Hello World!

Node.js script example

You can also create a basic HTTP server to load a site.

  1. Create a file in your application directory ( named app.js with the following code:
    var http = require("http");
    http.createServer(function(request, response) {
      response.writeHead(200, {"Content-Type": "text/plain"});
      response.write("Hello World. This page is running Node.js version: ");
    • This HTTP server will listen on port 8888.
  2. Start the server by running the following:
    [server]$ node app.js

    Viewing your domain with a port bound to it only functions for VPS and Dedicated Servers.

  3. Visit the page in a browser with port 8888 appended to the end. For example:
    If running correctly, your site will display the following:
    Hello World. This page is running Node.js version: v12.16.3
