Reasons to use Node.Js
Node.js has high efficiency and flexibility
Node.js is cross-platform
Platforms like Electron.js or NW.js allow you to build desktop applications with NodeJS. In this way, you can use some of your web application code in Windows, Linux, and Mac OS environments. In fact, with the help of NodeJS, the same team working on the web version of the product can build a desktop application without the need for specialized knowledge in C# or Objective C, or other languages used to build native applications.
Node.js can be combined with microservices
Most of the big projects were simple in the beginning and were introduced in an MVP version. But over time, these services became bigger and the need to add new features was felt in them. Sometimes expanding the service and adding new features to the product can become a nightmare for the development team. But a suitable solution to solve this problem is to use microservices. Microservices help you divide your application into small parts, each part can be written by a different team and even in a different language. NodeJS works very well with microservices.
Applications of Node.Js
Creating single-page applications (SPA)
SPA stands for single-page app and it is said that all its parts are implemented on one page. SPA is mostly used to build social networks, email services, video-sharing sites, etc. One of the most famous sites built in this way is the YouTube video-sharing service. Since NodeJS supports asynchronous programming well, it is considered a good choice for making SPA programs.
Making RTA programs
RTA stands for the real-time app. That is programs that have various changes in real-time. Most likely, you have worked with these types of programs before. For example, Google Sheets, Spreadsheets, or Slack are such programs. In general, interactive applications, project management tools, video and audio conferencing, and other RTA applications perform heavy I/O operations.
Creating a chat room
Creating online games under a web browser
