Top 10 Best Node.js Open Source Projects to Keep an Eye On

NodeJS is a server-side platform that’s built on the JavaScript Engine (V8 Engine) of Google Chrome. It’s an open-source, cross-platform runtime environment for JavaScript code execution outside the browser. The platform, being event-driven, works on a non-blocking I/O model, making it lightweight and effective in building web applications.

With the platform, you could simultaneously run code on the client and server side, hastening the development process. The growing popularity of the platform also has produced a range of open source projects and tools to help NodeJS development service providers work with the environment.

Why NodeJS on an Enterprise Level?

All programming languages could provide various reasons to choose them over others. With NodeJS however, it was crafted for at-scale apps. The modern tooling, and the embrace of a forward-looking manner of developing complex apps make it stand out among the rest.

Scalability and Performance

Built on the Chrome V8 runtime and written in C++, it is ultra-fast. Both Node and V8 are updated often, with security patches, performance boosters, and support for modern JS features. Using JavaScript also means that JSON data transformation—the most common web data interchange format is by default fast.

Node’s event-driven, single-threaded architecture enables it to handle several simultaneous connections with efficiency. The most popular web platforms create more thread for each and every new request, using RAM the entire time it takes to process it. Node.js on the other hand, operates on one thread, delegating tasks like database operations as soon as possible.

This makes it possible for it to handle thousands of concurrent connections. NodeJS furthermore, embraces app scalability, with robust features like Cluster module enabling load balancing over numerous CPU cores. Sturdy tools, like the PM2 process manager, makes monitoring, optimizing, and deploying Node apps easier.

Now, NodeJS is proving its worth as a game-changer, as developers could write JavaScript client-side and server-side coding. Thus, sending and synchronizing data automatically between these points is easy, which helps developers save time.
