Fiber is an Express.js inspired framework for Go, running on

fasthttp

(the fastest HTTP engine for Go). v3 brings generic support and better middleware.

Benchmarks: You need the absolute highest raw throughput.
Node.js Background: The API (
```
app.Get("/", ...)
```
feels like Express).
Zero Allocation: Obsessive memory optimization.

Doesn't use

net/http

. Much faster but incompatible with some standard library middlewares.

Spawn multiple processes (SO_REUSEPORT) to utilize all cores.

Do:

Use
v3
: For stable generic support.
Be careful with Prefork: Can cause issues with socket connections if not handled.
Use Built-in Middleware: Cache, Compress, CORS are highly optimized.

Don't:

Don't hold references:
```
fasthttp
```
reuses context objects. Copy strings if you need them after handler returns.
