To add to this - if you would like to implement a graceful shutdown that is triggered by an interrupt signal, you could do something like the following:

package main

import (
    "log"
        "fmt"
        "github.com/gofiber/fiber/v2"
        "os"
        "os/signal"
)

func main() {

        app := fiber.New()

        c := make(chan os.Signal, 1)
        signal.Notify(c, os.Interrupt)
        go func() {
                _ = <-c
                fmt.Println("Gracefully shutting down...")
                _ = app.Shutdown()
        }()

        // ...

        if err := app.Listen(":3000"); err != nil {
                log.Panic(err)
        }

        fmt.Println("Running cleanup tasks...")
        // Your cleanup tasks go here
}

Take a look at app.Shutdown: https://github.com/gofiber/fiber/blob/5d8e5339464fdbddc46db44534e9e00446adc3cc/app.go#L550
