However, when it comes to server-side development, the progress had been very little from its side; until NodeJS for backend came under the spotlight.
The choice of backend technology can ultimately affect how efficient any project is as a whole, how long it will take to be completed, how it will perform at the market, how much it will cost, and how extensive its maintenance will have to be.
In traditional web response programs, the client-side was always the one that initiates the communication.
But because of NodeJS, the developers now have a technology that can help them work in an asynchronous, event-driven I/O paradigm with real-time, two-way connections.
It allows us to create web-based applications where exists real-time data exchange capabilities between the client and server sides, which both of them can initiate as well.
NodeJS has become very critical in the technical stacks of many large-scale industries due to the advantages that it offers.
The main purpose behind the creation of NodeJS was to build a well-structured and light-lift technology in terms of processing power.
This, of course, means that the single thread that NodeJS uses is shared by all of the client’s requests. If we were to perform heavy computations within those requests, it will easily get choked up.
This in turn could mean that any more of the incoming requests will get blocked by the CPU. Hence, it should be kept in mind that NodeJS is not to be used in heavy computational tasks.
Another thing that should be kept in mind is that no exception should be left in the node event loop. This can be achieved by following a technique of not throwing the errors, but instead parsing them back to the caller as its parameters.
Failure to do so might cause the instance to terminate and the application to crash.
One of the biggest advantages of using NodeJS due to its functionality and the way it operates is speed…
Whether it be the speed of client-server communication, data processing, and transfer, or the speed of development, NodeJS shines in each category. Its unique I/O model provides exactly what is required from the web servers by modern applications.
Its ability to process every request in a single thread keeps the application running smoothly until the computations are not too intensive.
The following are some of the key advantages that can be gained from programming your backend in NodeJS;
NodeJS has entered a stable mature state where it has constructed a sturdy and ever-developing community & atmosphere around itself. In fact, its package manager, npm, is now the biggest software program registry on the web.
Tools like TypeScript and Flow emerged to provide a kind of language security. The async/await feature of NodeJS completely changed the way asynchronous code is written, almost making it look and behave like a synchronous piece of code.
NodeJS creates a runtime environment that is most suitable for developing real-time applications that process tens of thousands of online requests on the client side.
These are the requests that are not heavy in computation, neither do they require advanced security features.
Due to the ability of NodeJS to simultaneously handle multiple requests from the client-side, and respond quickly, it can be used to build a more client-focused web app.
This includes live chats, instant messengers, online games, video conferencing and e-commerce services, and collaborative platforms for multiple users (Google Docs, Trello, Dropbox, etc.)
The requirements for skills for programmers have been greatly reduced with the introduction of NodeJS as a comprehensive solution for full-stack development, and the need to learn additional technologies has been eliminated.
Small projects can be handled by a single full-stack team, saving both time and money.
NodeJS is a fast developing and promising technology that possesses the ability to resolve any hurdles that your app development may encounter.
Its importance will only continue to shine among the developers and the software industries alike.
With the ever-growing community showing love for this programming language, and its reputation continuously increasing, NodeJS will certainly continue to provide benefits to the software industry that will exceed your expectations.
