Why should you use Node.js in your next project?

When is it a good idea to use Node.js over other technologies? Why Node.js and not another solution? This post aims to answer that question.

There are tons of alternatives to Node.js when it comes to building any kind of software.

Why is Node.js a good choice?

In this post I’ll tell you some good reasons to use it.

Node.js is JavaScript

JavaScript is probably the most popular programming language in the world.

It is the only language that can run inside a Web Browser, which gives it a unique point of advantage over any other language.

With the rise of React Native, Electron and similar solutions, it’s also the only language which you can use to create web apps, frontend and backend, mobile apps, desktop apps.

It’s pretty universal, and once you master the JavaScript language in one area, your skills can be easily ported into another area and you just need to learn the environment differences (for example, how to use React Native rather than Electron, or the DOM).

This is something you will not find anywhere else.

Plus, JavaScript is an amazing and flexible language to work with.

If you already know JavaScript because you work in the browser, then it’s a no-brainer to pick Node.js.

Node.js is event driven and single threaded

What does this mean? In short, it can handle heavy load very well.

Every single Node.js program can manage a lot of concurrent connections, and still be very fast because of its non-blocking I/O nature.

This means that you have all the tools in place to build a very performant system, out of the box.

Node.js is hugely popular

This has a few side effects.

First, you’ll find the solution to any kind of problem discussed online. The community is huge and very helpful.

It’s easy to get started, and there are many resources to learn from.

Second, there is a library for everything.

The npm repository has a huge set of ready-to-use libraries, available with a simple npm install command.

Thanks to this popularity, a vicious cycle is set up: your favorite API might only offer an official Node.js library, and other languages are not even considered, left for unofficial packages (with varying level of quality).

You can easily deploy Node.js apps

Some programming environments require a dedicated setup, even for simple projects, because no one has built an ecosystem around them.

Heroku famously made Rails applications development simple, and today in Node.js we have other solutions that are comparable.

I am thinking about Zeit Now.

When I want a place to easily set up a sample Node.js application and share it with the world, I think about Glitch (hint: it can also run private apps).
