如何在终端重新加载 Go 光纤？

Question

I am completely new to this community but would really appreciate if someone can help me with this problem I am facing. I am currently following the basic tutorial of the simple Hello World app but how can we update the code to say something else and that to be updated in our output on the browser in real time?

package main

import (
    "log"

    "github.com/gofiber/fiber/v2"
)

func main() {
    // Fiber instance
    app := fiber.New()

    // Routes
    app.Get("/", hello)

    // Start server
    log.Fatal(app.Listen(":3000"))
}

// Handler
func hello(c *fiber.Ctx) error {
    return c.SendString("Hello, World 👋!")
}

Answer 1

You're talking about hot-reloading (live-reloading). Go itself do not have it implemented by default to achieve that, but you can do it with the package called air https://github.com/cosmtrek/air . Here is a great tutorial how to use it with Fiber: https://dev.to/komfysach/go-live-reload-using-air-40ll

Answer 2

you can use nodemon

install nodemon ' nodejs required'

npm install -g nodemon

and use the command to enable hot-reolading

nodemon --watch './**/*.go' --signal SIGTERM --exec 'go' run main.go
