[si3nloong]

How do we achieve something like this (https://echo.labstack.com/cookbook/subdomains) using fiber?

I didn't test it, but it should work 👍

package main

import (
    "log"

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

type (
    Host struct {
        Fiber *fiber.App
    }
)

func main() {
    // Hosts
    hosts := map[string]*Host{}

    //-----
    // API
    //-----

    api := fiber.New()
    api.Use(middleware.Logger())
    api.Use(middleware.Recover())

    hosts["api.localhost:3000"] = &Host{api}

    api.Get("/", func(c *fiber.Ctx) {
        c.SendString("API")
    })

    //------
    // Blog
    //------

    blog := fiber.New()
    blog.Use(middleware.Logger())
    blog.Use(middleware.Recover())

    hosts["blog.localhost:3000"] = &Host{blog}

    blog.Get("/", func(c *fiber.Ctx) {
        c.SendString("Blog")
    })

    //---------
    // Website
    //---------

    site := fiber.New()
    site.Use(middleware.Logger())
    site.Use(middleware.Recover())

    hosts["localhost:3000"] = &Host{site}

    site.Get("/", func(c *fiber.Ctx) {
        c.SendString("Website")
    })

    // Server
    app := fiber.New()
    app.Use(func(c *fiber.Ctx) {
        host := hosts[c.Hostname()]
        if host == nil {
            c.SendStatus(fiber.StatusNotFound)
        } else {
            host.Fiber.Handler()(c.Fasthttp)
        }
    })
    log.Fatal(app.Listen(":3000"))
}

Hello, how to achive the same with fiber v2?

[deliri]

This doesn't appear to work for version 2.
host.Fiber.Handler()(c.Fasthttp)
throws an error.

[sersh88]

host.fiber.Handler()(c.Context()) works for v2
