What is NodeJS used for?
Node. js is primarily used for non-blocking, event-driven servers, due to its single-threaded nature. It’s used for traditional web sites and back-end API services, but was designed with real-time, push-based architectures in mind.
Uber, Trello, and other renowned apps were built with Node.js. Simple code sharing, large development community, mild learning curve, and fast performance are among the main benefits of this technology.
So, what future awaits Node.js?
5 Core Features of Node.js
Node.js has a strong capacity to handle several requests and instant responses. Also, this technology contains the next 5 features that makes it a suitable option for web app development:
- ASYNC hook is a main module in Node.js that has an API to track asynchronous resources — objects with a callback — in a Node’s app.
- Node Package Manager (NPM) is the instrument that publishes the open-source projects written in Node.js. Also, it ensures package installation, dependency and version management.
- Single-threaded model is the system that processes, prioritizes multiple tasks and executes them in the asynchronous way.
- NODE_OPTION ensures that command lines can be implemented in the environment variable — a dependency that runs a code.
What Tech Stacks Can Take Over Node.js
Node.js was one of the most popular technologies among software engineers in the beginning of 2020. About 18.1% sought for it across the globe.
But Node.js has competitive technologies in web development that are the following:
What it really means is that Node.js is not a silver-bullet new platform that will dominate the web development world. Instead, it’s a platform that fills a particular need. And understanding this is absolutely essential. You definitely don’t want to use Node.js for CPU-intensive operations; in fact, using it for heavy computation will annul nearly all of its advantages. Where Node really shines is in building fast, scalable network applications, as it’s capable of handling a huge number of simultaneous connections with high throughput, which equates to high scalability.
How it works under-the-hood is pretty interesting. Compared to traditional web-serving techniques where each connection (request) spawns a new thread, taking up system RAM and eventually maxing-out at the amount of RAM available, Node.js operates on a single-thread, using non-blocking I/O calls, allowing it to support tens of thousands of concurrent connections held in the event loop.
Okay, so this is Node.js points to remember in a nutshell.
