Fiber: 🤔 Does Fiber support Hot reload ?

[chocovish]

Just tried fiber. and the very first thing i feel missing was the hot reload.
I'm coming from a python background where Flask has a feature like development=True parameter to enable hot reload (reflect result in server instantly after changing the code).

@chococvish, we are planning to add this to Fiber, we are just not sure about the name yet.
Do you have any suggestions, and why we should name it x.

app.Settings.HotReload = true
app.Settings.RestartOnChange = true
app.Settings.AutoReload = true
app.Settings.AutoRefresh = true

import (
    "github.com/gofiber/fiber"
    "github.com/qinains/fastergoding"
)

func main() {
    fastergoding.Run() // hot reload
    app := fiber.New()
        ...

import (

  "github.com/qinains/fastergoding"
)

func main() {
  fastergoding.Run() // hot reload
  app := fiber.New()
        ...

This does not work for me since the server always restarts after adding fastergroding:

@sebastianbuechler Check https://github.com/gofiber/recipes/tree/master/air to enable hot reload. It works!
