Gone are the days when developers only used JavaScript as a client-side programming language. Today, when the area of application is impressively expanded, Node.js shines also in server-side programming. Let’s meet the best JS app examples.

Why use Node.js for developing web apps?

When it comes to rapid development, Node.js can easily compete with Java, Python, and Ruby on Rails. There are multiple reasons why both startups and large-scale enterprises use it e.g. for developing streaming or real-time web apps.

What is Node.js ?

Node.js is a cross-platform open-source runtime environment and library designed to run web apps outside of the client’s browser. It is composed of Google’s V8 JavaScript engine, the libUV platform abstraction layer, and a core library written in JavaScript. Node.js was created in 2009. Today, it is mostly used for server-side programming. It’s often utilized for non-blocking, event-driven servers like typical websites and back-end API services. It is worth highlighting that Node.js is a runtime, not a framework.

Main benefits of node.js application development

Here are eight benefits to answer the question of why Node.js is used by so many companies all over the world.

It offers strong corporate and community support

The list of companies using Node.js has been constantly growing in the last few years. It already includes hundreds of well-known industry leaders such as LinkedIn, Uber, and Netflix.

In a cross-functional team, each member is responsible for the entire lifecycle of the app. Cross-functional teams consist of front- and back-end developers, QA experts, infrastructure engineers, etc. Node.js is perfect for setting the microservices mindset and supports better agility, innovation, and smooth collaboration.

Cost-effective with full-stack JavaScript

JavaScript, as only a few programming languages, is great for both back-end and full-stack development. While using Node.js, you don’t have to combine several programming groups. Therefore, you can optimize the development costs. Also, no need to hire diverse teams of developers.

It reduces loading time

Node.js reduces loading time by quick caching. This helps developers save time while performing tasks. Quick caching is one of the reasons why companies build Node.js apps to be super-efficient and maintain live connections on their websites.

It offers better performance

Node.js apps guarantee great speed while developing web applications and sites. One of the reasons for the outcome lies in the asynchronous programming that the runtime enables. Also, don’t forget about the well-optimized Google V8 engine which boosts performance even more.

Easy to learn

Learning to build Node.js apps is relatively simple. Most developers admit that you only need a couple of tutorials to get the necessary tools for creating a project. Also, you don’t have to learn two programming languages for full-stack development which is another plus.

Preferred for developing cross-platform mobile apps

Node.js is perfect for those who need space and freedom to do things without sets of rules and guidelines. You can build applications that work across macOS, and Linux without having to develop on that specific operating system. Also, you can work on both web and desktop apps together.

It reduces the time to market of apps

Node.js enables you to set up servers quickly and build simple APIs in minutes. If you have a software idea that needs to be realized quickly, then Node.js is something you should for sure consider. Node.js allows you to reuse the components which reduces the time to market even more.
