ExpressJs and Spring boot are back-end framework that use to develop to the server side. ExpressJS is a javascript framework and Spring Boot is a Java framework. When we look at the git repos and stack overflow questions more discussed and used framework is ExpressJS.
Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
On the other hand, Spring Boot makes it easy to create both stand-alone and web applications, production-grade Spring based Applications that you can “just run”. We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.
Reasons to select ExpressJS are :
- Easy to install with Node package manager (npm).
- ExpressJS is open source. So there is a big community that supports express js and so many Great libraries are the to download via npm
- Great for API development
- Allows us to reuse code in the frontend
- Can build Real-time API’s
- Non-blocking IO model make the app lite weight
- Need to learn only one language for both front end and back end
- Support Cross-platform
Reasons to select Spring Boot :
- Relatively Powerful and handy than nodeJS
- Easy to set up the project and manage dependencies when used with maven
- Good for Cloud application development
- Integrations can be done with most the other Java frameworks
- Fast Performance for Microservices API’s
- Multi-threaded.So can handle different events at the same time.
Things to worry about
Node.JS
- Single threaded. One exception can crash the whole app
- Not a suitable technology to Asynchronous programming
- Dependency-based on GitHub
- Low computational power
Spring-Boot
- Heavy-weight when compared to Node.js
- Overwhelming memory consumption.
- Disk space consumption can also be overwhelming.
- Development requires a lot of time.
Conclusion
ExpressJS is a good light-weight framework to build the back end of a web application. But it’s not the ideal solution for complex projects. In the situations where several data types involved java performs better than ExpressJS. So it’s better to know both languages and use them in the perfect situation.
