Since developers work with JS for both front-end and backend, this allows teams to keep their work consistent, enhances their collaboration and understanding among each other. The team becomes cross-functional, that positively affects development time and costs. The code between the client and server can be easily reused and shared, which also accelerates the project development.
Real-Time Applications (RTA)
Node.js is perfect for real-time applications because, as mentioned, it handles multiple client requests, enables sharing and reusing library code, and assures fast data sync between front-end and backend. Node.js is a good option when you’re up to develop instant messaging, video conference, or collaborative editing apps (Google Docs, Trello).
Scalable and Robust Environment
Node.js processes many requests in short response times, shares validation code between the client and server, has non-blocking, event-driven I/O. These are the features that let this system to make your servers scalable and robust.
Not Suitable for Heavy-Computing Apps
Since Node.js is single-threaded, it’s not suitable for heavy calculations. CPU-heavy operations block the incoming requests and affect the app’s performance. In such way, the excellent performance, that is a remarkable point of all the apps with Node.js, will be neglected. If heavy-computing is essential for your project, you should search for another solution.
This aspect is another side of the coin of the creativeness mentioned above. Node.js make developers code the app from scratch. This influence the complexity of the project, time for development, and its cost.
Lack of Consistency
Changes are made to Node.js API frequently, and developers usually have to make changes to the code as well. Sure thing, this is not very convenient and efficient work on the project. This is why maintenance of the application is a high priority in a project with Node.js.
