I have been using ExpressJS for backend development for some time now, and I’m interested in exploring Bun as an alternative framework. While I’m familiar with ExpressJS and its ecosystem, I’m curious about the advantages and disadvantages of using Bun for backend development.

I appreciate any insights or experiences shared by developers who have worked with both frameworks or have knowledge of the strengths and weaknesses of Bun compared to ExpressJS.

Just want to know which one would be better. Can anyone provide insights into the following aspects comparing ExpressJS and Bun?

Performance: How does Bun compare to ExpressJS in terms of performance, especially under heavy loads and high traffic scenarios?
Developer Experience: Are there any notable differences in the development experience between Bun and ExpressJS, such as ease of use, learning curve, and developer productivity?
Middleware and Ecosystem: How does Bun’s middleware ecosystem compare to ExpressJS? Are there any limitations or advantages in terms of available middleware and integrations?
Community and Support: Considering ExpressJS’s extensive community and long-standing support, what is the state of Bun’s community engagement, documentation, and ongoing support?
Use Cases: Are there specific use cases or scenarios where Bun excels over ExpressJS, and vice versa?
