Express.js
Express is the minimal, unopinionated web framework that defined Node.js server development. Its tiny core leaves routing, middleware, and structure decisions to you.
Pros
- Minimal core. A thin routing and middleware layer with almost no imposed structure. 0
- Huge middleware. Thousands of packages cover auth, logging, and parsing. 0
- Easy to learn. A working API fits in a dozen lines of JavaScript. 0
- Ubiquitous. The default reference for Node tutorials, jobs, and answers. 0
Cons
- No structure. Freedom means large apps drift without team conventions. 0
- Callback-era design. Async error handling predates modern patterns and trips people up. 0
- Slow evolution. The core has stagnated while Fastify and Hono moved ahead. 0
- Manual everything. Validation, typing, and config are all bring-your-own. 0
