Why should we use Node.js?
- More security against the high server load, especially when DDOS attacks occur, while other server software such as SSH remains accessible and responsive.
- Nodjias is much faster than others like PHP and Ruby.
- The most common use of Node JS is for API(Application programming interface), which allows client-side developers to access and use data.
- Low response time: Nodejs is a single-threaded and asynchronous platform. None of the I/O-related processes stop other processes. This means that you can read a file from a disk at the same time, send an email, and query on a database.
- Many web servers are based on the Threading technique, which creates a thread for each request, and as a result, part of the RAM (for example, 1 MB) is occupied by the server’s memory. The Threading technique is not suitable for tasks that require a large number of simultaneous connections. But in Node js, each request made to the web service does not create a new js process.
- This allows the frequently called functions to significantly improve the speed of code execution by turning into codes.
- The ultimate reason for using Node.js is its large community of programmers and its open-source libraries. Most of the time you will need a pre-defined library that you can use and you don’t need to code for many of your basic principles and basic concepts.

Advantages and disadvantages of Node JS
Airbnb, LinkedIn, Walmart, Uber, and even NASA have used Node.js to produce their products. Many small and start-up companies use technology to build applications. The benefits of Node.js are innumerable, but you should also be aware of its limitations. Get a complete picture of Node.js and avoid serious developmental errors that can be costly
Where to use Node.js?
It is a great option for applications that need to process large volumes of short messages that require a short delay. Such systems are called real-time (RTA) programs and can be easily developed with Node.js. Thanks to its features, Node.js is a good choice for real-time drawing/editing programs where you can see documents that have been live and instantly modified by someone else.
Fast and scalable environment
If you have a lot of requests, Ruby on Rails may not be fast enough. Node.js has proven to be somewhat faster and more scalable than Rails. Node’s ability to process large requests with low response time, as well as sharing code validations between the client and the server, makes it a great option for modern web applications that do a lot of processing on the client-side.
When might Node.js not be the best idea?
While Node.js is great for building applications in many cases, there are still some things that aren’t good and shouldn’t be used.
The first thing that comes to mind, is heavy computing. Event-driven is a non-standard I/O model that uses only one CPU core. Heavy CPU operations only block incoming requests, and providing the greatest benefit of Nodejs is useless. If you are thinking of building a heavy CPU software, try to use a different and more appropriate technology that will give you better results.
Finally, using Node js for HTML and CRUD programs where you don’t need a separate API, and all data comes directly from the server is useless. Your app may be more scalable, but don’t expect more traffic to your app just because you’ve used this platform, in which case you’ll need to use frameworks like Ruby.
This platform will become one of the most important languages for business development in the near future. If you are looking, to start with Node JS, you can use our Windows or Linux virtual private server, which are fully compatible with the Node JS language and are optimized.
