At the very beginning, Node.js application development became popular mainly because of the mechanics – as opposed to most runtime environments that utilize multi-threaded processing models, Node.js is single-threaded. It means that every request uses a single main thread utilizing event loops to run blocking Input/Output operations in a non-blocking way. This enables better performance and better scalability. Multiple concurrent clients can be handled without creating multiple threads which removes the performance cost of thread context switching. Also, you can avoid errors that arise from incorrect thread synchronization.

Very often, while developing applications it’s difficult to build low-latency live servers with open bidirectional connections due to the architecture. To achieve that, a lot of development effort and workload is required. In Node js app development, you don’t have to spend time fighting with discrepancies of encoding and modes. It offers a lot of space and freedom for doing things your own way in real time. You can build everything from scratch and tailor every detail. This also includes adding features from a fresh install with few restrictions. As Node.js uses a V8 engine, it’s fast and resource-efficient.

Caching is storing data in a high-speed storage layer so that future requests for such data can be fulfilled much faster than it’s possible through accessing its primary storage location. When it comes to software development, caching’s main objective is to improve the software’s response time by reusing previously retrieved or computed data. Node.js offers impressive caching performance which means the server load can be reduced to the minimum. Also, the software reliability is increased, and, on the other hand, network costs can be decreased because far less data is transferred to and from the content origin. Database performance is also improved. As the speed at which the app processes data is a major performance consideration when designing the architecture, Node js app development may be a good choice.

Of course, it’s Libuv for Node.js. Libuv is a C library that was written for Node.js to abstract non-blocking I/O operations. It is necessary to prevent wastage of system resources e.g. when a program is querying the database and the CPU sits idle until the query is processed. The library also includes a thread pool to distribute CPU loads. This enables blocking operations that cannot be done asynchronously at the OS level.

Before Node.js was developed, JS was only used for client-side development. For server-side development, developers had to use a different programming language. Now, an experienced Node js development team can write both front-end and back-end JS apps which makes the development process more efficient and much easier. Full-stack development services are more and more popular mainly because they enable high performance. Developers can create fully asynchronous apps by taking full advantage of non-blocking programming. Also, the web apps entirely written in JS provide a better user experience and quality. What is more, development efficiency is better which leads to cost reduction.

JS is one of the most famous programming languages for front-end development. It is widely used by developers from all over the world. It is relatively easy to switch to using Node.js at the back end, then. As Node.js has no steep learning curve, it’s quite simple to grasp when you already know JS and object-oriented programming. Even if you are a JS junior developer, you don’t need much effort and time to learn Node.js and work with it. Most developers say that the most difficult thing is to catch up with the asynchronous flow.
