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