How to import sub-routes from other packages

Question

Instead of writing every route under main(), like

func main() {
    e := echo.New()
    e.GET("/api", sayHello)
    e.GET("/api/music", getMusic)
    e.GET("/api/user/:id", getDetail)
    e.POST("/api/user", addUser)
    // ...
}

How can I import these all sub-routes from a file called api.go, and use those in the main function? Similar to

import "./API"
func main() {
    e := echo.New()
    e.UseSubroute(API.Routes) // <-- similar to this
    // ...
}

The Echo object does not have this method. I think you need the code?

API.go:

package main

import "github.com/labstack/echo"

func UseSubroute(echo *echo.Echo)  {
    echo.GET("/api", sayHello)
    echo.GET("/api/music", getMusic)
    echo.GET("/api/user/:id", getDetail)
    echo.POST("/api/user", addUser)
}

main.go:

package main

import "github.com/labstack/echo"

func main() {
    e := echo.New()
    UseSubroute(e)
}

These two files need to be placed in the same directory.

Do you need it?
