What is Node.js?

Because of its single-threaded nature, Node. js is best suited for non-blocking, event-driven servers. It was created with real-time, push-based architectures in mind and is utilized for standard websites and back-end API applications. Node.js is a runtime environment based on Chrome’s V8 JavaScript engine, rather than a framework or library.

Ryan Dahl originally demonstrated the technique at the annual European JSConf in 2009, and it was quickly dubbed “the most fascinating single piece of software in the present JavaScript world.”

The rise in popularity of JavaScript has resulted in many changes, and the face of web development today is very different. Things we can accomplish on the web now with JavaScript running both on the server and in the browser were unimaginable only a few years ago.

With that all well said, let’s see the pros and cons of Node.js.

Node.js Pros and Cons

Fullstack JavaScript Development:
Node.js has made it possible for JS to be used on the server side. Companies and startups may now use a single programming language to create both the backend and frontend of their products. In terms of development, you save time and money by not having to hire as many people because a team of JS-savvy developers may be enough to get the job done.
Heavy Computations:
Node.js is an excellent tool for creating complex projects. When dealing with CPU-intensive jobs, however, this is not an option. There is a large performance loss due to incoming request blockage by expensive computations. As a result, it is unsuitable for long-term computations.
Asynchronous non-blocking input or output:
You won’t have any issue processing hundreds of thousands of requests at once using Node.js. The data flow is unaffected, resulting in lower RAM use and faster performance in practice.
Database Hell:
Dealing with relational databases is a pain if you are using Node.
Microservices Architecture: 
Microservices architecture is becoming more common than monolithic design in today’s world. As a result, a number of well-known corporations, including Netflix, have begun to separate their apps into smaller services. In addition, the technology provides a large number of ready-to-use modules as well as an event-driven I/O architecture for microservices implementation.
Callback Hell:
This problem can degrade the quality of your JS code and lead to other problems like development delays and expense hikes. Callback hell is a condition generated by the execution of several asynchronous activities, in which a callback function is created from a multitude of nested callbacks. As of the seventh release, you can use the async/await capability to avoid difficulties with callbacks. They do not, however, promise to totally avoid them.
Rich Ecosystem:
The availability of ready-to-use tools for creating Node apps boosts development efficiency significantly. As a result, three letters – N, P, and M – should be memorized. They’re referring to the JS package manager, which now has over 700,000 components. Lines of code can be searched, installed, shared, and reused with NPM.
Without diving in-depth into JavaScript, if someone starts Node, he may face conceptual problems.

When should you use Node.js?

  1. Single-page dynamic applications (SPAs)
  2. Angular, JQuery, React, Angular, and other frontend technologies
  3. MEAN stacks are examples of software stacks (Angular, MongoDB, etc)
