Before we get into the advantages and disadvantages of using Node JS, let me give you a brief idea about Node.js.
It is an open source, cross-platform runtime environment for developing server-side applications. Built on Chrome’s V8 Java Script engine, Node.js uses non-blocking, event-driven input output model, thereby making it efficient and lightweight. Npm, Node.js’ package ecosystem is revered as one of the largests open source libraries of the world.
Let’s quickly shift our focus back to advantages and disadvantages.
Top advantages of Node.Js
1. Node js is fast
2. Java Script language
3. Open source
Node js is open source runtime environment and is free to use under MIT license. Node js is the cross-platform which runs on windows, mac, Linux.
4. Active community support
Node.js Community is an inclusive network of developers who come together to discuss, learn and contribute to the various projects. This community is also active on GitHub.
5. Asynchronous I/O
Node JS experts India firms use asynchronous programming. Every I/O operation is non blocking, you can do multiple operations at the same time. Users can easily send multiple mails, database operations and read files simultaneously.
"A coin has two sides, similarly Node.js has it’s own set of disadvantages."
Disadvantages of Node.Js:
1. Not suited for CPU-intensive tasks
The Event Loop is the main feature of Node js, and there may be too many callback are running in your code. So Node js is not also suited for CPU-intensive tasks, if you are doing that it might slow your application.
2. Not effective with large scale applications
Node js does not support multi-threaded programming this is the reason why it is only preferred for the lightweight applications (online games ,chat ). If you are using it for heavy applications, your choice is wrong.
Node.js API has some consistency issues. Most of the times the new API comes with many backward changes, then the programmers are required to make changes in the code to make it compatible.
4. Poorly supported to relational databases
Most of the times relational databases behave strange while working with node js. If the issue persists, the developers can use No sql database(mongo DB) in Node js. It takes away the extra effort to learn new databases.
