Node.js is a great fit for SPAs because it can handle asynchronous calls and heavy workloads of these applications. Single Page Applications (SPAs) are used to create social networking applications. Node.js uses powerful event APIs that make it easy to manage server-side events and push notifications which are widely used in real-time applications.
Here are some of the most important applications of Node.js that you will learn in this Node.js tutorial. While numerous libraries are available for extending Node's functionalities, the engine comes with a set of core modules implementing basic is a fast, lightweight, and scalable platform that can be used efficiently for developing many kinds of web applications. Node.js is a Javascript engine (Google's V8 engine for Chrome, written in C++) that allows to run Javascript outside the browser. The created server can then be accessed with the URL or in the browser.Ī simple web page will appear with a “Hello, World!” text at the top, as shown in the screenshot below. In this case, if we name it hello.js we can run the application by going to the directory the file is in and using the following command: node hello.js Http.createServer((request, response) => ).listen(1337) // 4. const http = require('http') // Loads the http module To create the application, create a file containing theįollowing JavaScript code. The http module provides the functionality to create an HTTP server using the http.createServer() method. The http module is a Node.js core module (a module included in Node.js's source, that does not require installing additional resources). Note that, instead of using port 1337, you can use any port number of your choice which is currently not in use by any other service. In this example we'll create an HTTP server listening on port 1337, which sends Hello, World! to the browser.
