Node.js as Your Back End-When and Why

Node.js as Your Back End-When and Why

With JS being highly popular and effective for use, Node.js seems to progress rapidly. What is Node.js though? Simply said, Node.js is a JS runtime environment that allows you to build server-side applications։ you use JS for your back end, which happens to have very light and efficient use. So let’s go over several benefits of Node.js and learn more about dos and don'ts.

Decreases costs and saves time

An advantage of Node.js is it is an open-source technology. Due to Node being of light use, you do not have much to worry about choosing it as your back-end development tool. Imagine how efficient Node.js would be in cutting costs as you apply the reusable codes for both the front end and back end. This helps you write applications much faster due to the various techniques it offers. After all, Node.js advances rapidly, and as time goes on, it is getting more popular, which means you will not have a lack of sources and knowledge. Moreover, you would have less to worry about your web development team as a good team of JS specialists could take care of it all.


Is great for real-time applications

Both client and server-side communication is easily managed through Node.js. It helps you build applications allowing much easier data exchange for both sides. Applications allowing large numbers of online requests can be developed in Node.js as it makes the process much faster and lighter. Such examples are gaming apps, collaborative documents, video conferences, and chats or E-commerce websites.



A key advantage of Node.js is its scalability in processing multiple simultaneous requests, which provides fast performance. On the other hand, Node does not support CPU-heavy operations.


Large companies using Node.js

With Node.js gaining success among many, large companies in the industry have chosen to use Node for their web applications. Companies like Uber, LinkedIn, Walmart, Paypal, and NASA use Node.js for the back end. The list goes on and on as each company has used Node for a specific purpose and benefits. Node, therefore, has proven to be the right tool to use for the very application.

When Node.js might not be the best solution


Node.js is single-threaded, so it will not be the best solution for CPU-heavy operations. Node.js might not be the best use for applications getting the data straightforwardly from the server: you basically cannot expect high traffic.
