Unlock Endless Possibilities: Learn How to Install Node.js and NGINX on Ubuntu 18.04

In this guide, you will learn how to install and configure NGINX on an Ubuntu 18.04 Linode in order to create a reverse proxy to a running Node.js server. Node.js is an open-source JavaScript runtime environment that is often used to create and serve web applications, and NGINX is commonly used to serve Node.js applications. After the installation and configuration of NGINX is complete, you will create a test JavaScript file in order to check that your Node.js server is running properly. Thus, with the help of this guide, you will be able to serve dynamic and responsive content from your Node.js server with the help of NGINX.

Learn How to Easily Create a Test JavaScript File and Take Your Coding Skills to the Next Level!

In the Install and Configure NGINX section, you configured NGINX to listen on port 80 to serve its static content, as well as a reverse proxy to your Linode’s localhost:3000 when a request for the /test.js file is made. Consequently, in this section, you will create the test.js file to be able to test your Node.js web server, which will be created in the next section.

  1. Put Your Tests to the Test: Create a test.js File in the Root Directory of Your Site!

fs = require("fs");

http.createServer(function(request, response) { //Create server
var name = url.parse(request.url).pathname; //Parse URL
var filename = path.join(process.cwd(), name); //Create filename
fs.readFile(filename, "binary", function(err, file) { //Read file
if(err) { //Tracking Errors
response.writeHead(500, {"Content-Type": "text/plain"});
response.write(err + "\n");
response.writeHead(200); //Header request response
response.write(file, "binary"); //Sends body response
response.end(); //Signals to server that
}); //header and body sent
}).listen(3000); //Listening port
console.log("Server is listening on port 3000.") //Terminal output
