Node.js Course – The Complete Node.js

In this course, you’ll learn the basics of Node.js and how to build a basic web app using it. A JavaScript-based development tool called Node.js is used to create mobile and online applications. With the use of extra developer tools, you can also utilise it to make desktop programmes. Node.js is perfect for creating chat and gaming apps since it can handle asynchronous tasks, but it can be used to create a wide range of applications. You may learn how to use Node.js in a variety of ways by taking Node.js courses on Udemy.

Node.js is a server-side JavaScript platform that uses an event-driven, non-blocking I/O model to achieve scalability and high performance. It has been described as “JavaScript on steroids”.

Regarding this course

One of the most widely used programming languages is JavaScript. Professional developers have been found to most frequently employ the robust Node.js runtime environment. An event-driven JavaScript runtime is Node.js. Node is a fantastic environment for developing effective network applications, among its many other potential uses for JavaScript development.

Takeaway Techniques

This course is a fantastic way to learn about the ideas behind server-side web development. You’ll develop experience with the Node.js runtime environment and discover the various components that make up a website or web application’s back end. After completing this course, you’ll be prepared to investigate well-known Node frameworks like Express.js and create robust applications.

Node.js can be used for many things including:

  • building fast, scalable network applications
  • creating realtime apps using WebSockets and Websocket Lite (a subset of WebSockets)
  • developing web servers with zero downtime

The basics

Node.js is a runtime environment for JavaScript. It uses the V8 JavaScript engine, which was originally developed by Google and supports many of the features in ECMAScript 6 (the latest version of the ECMAScript standard).

Node.js uses its own package manager called npm to manage dependencies between modules, but it also allows you to use other package managers like bower or grunt when developing your application with Node.js in mind as well as being able to run your code on multiple platforms including Linux, Mac OS X, Windows 10 64-bit (including Server), FreeBSD 11 64-bit (including Server), Solaris 11 SunOS 4 Solaris 10 SPARC V9 NetBSD 7 NetBSD 6 OpenBSD 5 OpenDarwin 4 FreeBSD 8 DragonFly BSD 4.* FreeBSD 9 FreeNAS 9 Fugu 0r1 or 2r2 Gentoo Linux RipeVM 1 LFS 0r0 or 1r2 OS/2 Warp 3 NeXTstep R532/386 R6XX/6000 Targa32/64

Working with the file system

The file system is a central part of Node.js, so it’s important to know how to work with it.

The fs module provides access to the files on your computer and directories within those files. You can use the readdir and readFile functions, which return an array containing information about each directory or file they’re passed as arguments. This can be useful when you want to process large amounts of data in an efficient manner (for example, by using a streaming API).

You’ll also need writeFile() , which allows us write data into your existing directory structure:

HTTP

HTTP is the protocol that allows us to make requests to a server. It’s easy to use and you can do it in your node program!

You can use HTTP in two ways: as an express request, or as a standalone module.

Using Express:

Express is a web application framework for NodeJS that allows you to build web applications fast without having any code knowledge whatsoever. If you want more details about how this works then check out [this tutorial](https://www-coursehub-com/nodejs-courses/nodejs-gettingstarted/) on CourseHub where we go over each step of creating an app using Express framework with examples from scratch until completion – from setting up environment variables (like database connection string) through deployment process itself (deployment script), including all steps required for deployment process itself, which includes verifying no errors occurred during deployment process etc…

node.js is a great way to build web apps.

Node.js is a great way to build web apps. It’s easy to learn and use, fast and scalable, highly concurrent and event-driven. Node.js is used by companies like Uber, Netflix and PayPal to run their backend services—and you can use it too!
