Technically speaking, Node.js is a server-side platform, built on Google Chrome’s V8 Engine for building fast and scalable network applications. Node.js uses a non-blocking I/O model which makes the platform ideal for data-intensive applications that run across distributed devices.
The list of companies that use Node.js should open your eyes as to what this runtime engine is capable of. The list includes the likes of:
But why should your company be using Node.js? Let’s take a look at a few reasons.
This is made possible by the Event Loop, which is (basically speaking) a program that waits for events and then dispatches them once they’ve occurred. Because Node.js uses event-driven programming, it results in very fast applications.
Event-driven applications work with a loop that listens for events and then triggers a callback function when an event is detected. In fact, everything that happens in Node is a reaction to an event. With event-driven programming, the amount of resources used is considerably less than traditional development, so you can get more (data processing) from less (server hardware).
Common uses for Node.js include:
There are a number of important Node.js features, all of which would benefit your business.
You won’t be using Node.js alone. There are a number of frameworks you should become familiar with before you dive too deep into Node.js. The list of frameworks includes:
Node.js is an outstanding tool for most businesses. That doesn’t mean it’s perfect. There are a few drawbacks to consider when adopting this technology.
For example, Node.js isn’t a good option when you’re dealing with CPU-intensive tasks and long-running calculations. Because of incoming request blockage by large computations, you’d experience a significant loss in performance with Node.js.
Another drawback of Node.js is a lack of consistency. The Node.js APIs change frequently, and those changes aren’t always backward compatible.
You will also have to write everything from scratch. Because of this, your productivity could take a hit—especially if you’re new to the language.
Finally, not all of the tools are mature and have been poorly documented. Because much of the Node.js ecosystem is open source, a lot of the documentation can wind up out of date or poorly written.
Over the last few years, the popularity of Node.js has been steadily increasing. Huge companies
