18 Best Free Node.js Tutorials To Improve Your Coding Skills 2023

Node.js is the most widely known server-side framework for building fast and scalable applications, and software. Since the framework’s inception in 2009, Node.js is now being used amongst the largest corporations in the world, including the likes of Amazon, PayPal, Yahoo! and others. The ‘npm’ (Node Package Manager) is the biggest library of open-source modules and libraries for accelerating the development process, and all Node.js developers depend on ‘npm’ for rapid development.

Getting Node up and running has never been easier, with plenty of tutorials and a huge community to voice their opinion on concerns from beginners, Node.js has become a truly game-changing framework that we see not only in apps today, but also physical hardware, like smartphones and drones. The framework has seen a lot of potential already, and has often proved that it is the primary choice for networks and large database oriented websites that want to achieve high-speed results, without compromising their power resources. And so much more is coming to Node this year, and in the years beyond.

Many might argue about Node.js extended popularity and how reliable it can be for new developers, though constantly seasoned front-end and back-end developers publish articles, such as this one, discussing the comfort they experience when using Node, compared to any other alternative out there. We wholeheartedly agree about Node.js performance, and to help our readers become more experienced with the framework, we are offering a little short of 30 unique Node.js tutorials that have been published only in the recent few months, giving you a truly updated list of resources that will help you to learn the latest creative tricks, and performance tips on how to make the most of Node.js!
