Tell us about your feature request

As currently there is no middleware feature especially for panic recovery, if anyone agrees, I can submit a PR.

Example:

Default Fiber

$ curl -i -H "Accept: application/json" http://localhost:8080/panic
HTTP/1.1 500 Internal Server Error

I'm an error

In the logger:

2024/04/08 00:04:27 [H0llyW00dzZ Project] [CRASH] Panic occurred: I'm an error
2024/04/08 00:04:27 [H0llyW00dzZ Project] [CRASH] Stack trace:

A Better Panic Recovery by Manipulation

$ curl -i -H "Accept: application/json" http://localhost:8080/panic
HTTP/1.1 500 Internal Server Error

{"error":"Internal Server Error"}

In the logger:

2024/04/08 00:06:47 [H0llyW00dzZ Project] [CRASH] Panic occurred: I'm an error
2024/04/08 00:06:47 [H0llyW00dzZ Project] [CRASH] Stack trace:
goroutine 28 [running]:

        C:/Program Files/Go/src/runtime/debug/stack.go:24 +0x5e

[!NOTE] This is a method to manipulate panic, because by default, Fiber shows the panic in the front-end.

It works well in combination with a rate limiter for scalability:

$ curl -i -H "Accept: application/json" http://localhost:8080/panic
HTTP/1.1 429 Too Many Requests
Server: H0llyW00dzZ Project
Date: Sun, 07 Apr 2024 17:40:23 GMT
Content-Type: application/json
Content-Length: 54
Retry-After: 44

{"error":"Too many requests, please try again later."}
