Node JS development services

First of all, it is worth noting that Node JS is a backend cross-platform runtime environment based on the V8 JavaScript engine. For your web application to function correctly, it has to have both a frontend (client-side) and a backend (the entire logical structure of the application). Node JS allows you to build an application entirely based on one of the most popular programming languages - JavaScript. Web development language unification makes the application scalable, fast, less buggy, and easier to manage. It is an open-source technology, which means everybody can use it for free. In short, Node JS is a solution responsible for the application's logical structure, communication with the webserver, and development with its use can be described as full-stack.

Node.js is used mainly for building applications that need to constantly update data, such as chats, video conferences, or scalable network applications. Such uses arise from its nature. Non-blocking Input / Output and asynchronous request handling allow the application backend to process requests without delay. Non-blocking Input / Output is directly connected with asynchronous processing, as it allows requests to be processed without blocking operation in the thread. We believe that another thing worth mentioning is that requests in Node.js are processed on multiple threads. That's why Node.js applications can process various concurrent requests simultaneously. On the other hand, the whole event loop runs on a single thread.

Node.js stands on microservices architecture. It means that applications developed with Node.js don't have one big score, but rather the app's logic is split into smaller modules. Node.js apps are more flexible, and future iterations are made simple thanks to such a solution.

There are multiple applications developed with Node.js that have suffered market success. Two of the most interesting examples are given below. When it comes to complex single-page applications, Netflix is ​​the best example. Their web application is built with Node.js on the backend and React JS on the frontend. Most of us used the Netflix web app at least once and have seen with our own eyes how fast javascript-based applications are. Interestingly, Node.js can also serve as a backend for mobile apps. This solution was used by LinkedIn when building their mobile application. They replaced the previous ruby-on-rails technology with Node.js, which gave them a tenfold performance boost! It only shows that developing social networking apps using Node.js is a great idea! If you want your application to be found in answer to such a question, please contact us!

Node.js is single-threaded (event loop), although it uses many threads in the background to execute asynchronous code using the libuv platform abstraction layer (worker pool). The event loop is responsible for logging callbacks for future use. The event loop runs on the same thread as all JavaScript code. The Worker pool is responsible for creating and maintaining multiple separate lines that execute task data and then return the result to the main thread-event loop.

Node JS may become the choice of many companies when developing their web applications. The startup market also shows great interest in this technology. There are many reasons for this, but the most important is saving time and money. Node.js development allows for speedy code delivery, and thus, since it is a JavaScript-based solution, it is much faster to create a frontend to the application. Using JavaScript as a Node JS basis also means it's a very cost-effective solution as the same team can make both the backend and frontend of your application. You can also mention that the applications created in Node JS are very scalable because they can handle a massive number of concurrent connections, thanks to the microservices structure. Of course, there are many more benefits of choosing Node JS for your software development projects, but it all depends well on the nature of the projects.
