Mounting Sub-Router

When having multiple instance of a router you might want to mount one as a sub router of another under some route path, still keeping all middleware.

It doesn't have to be gorouter. You can mount other routers as well as long they implement http.Handler interface.

Mount

net/http

valyala/fasthttp

package main

import (
   "log"
   "net/http"

   "github.com/vardius/gorouter/v4"
)

func main() {
    router := gorouter.New()
    subrouter := gorouter.New()

    router.Mount("/{param}", subrouter)

    log.Fatal(http.ListenAndServe(":8080", router))
}

package main

import (
    "log"

    "github.com/valyala/fasthttp"
    "github.com/vardius/gorouter/v4"
)

func main() {
    router := gorouter.NewFastHTTPRouter()
    subrouter := gorouter.NewFastHTTPRouter()

    router.Mount("/{param}", subrouter)

    log.Fatal(fasthttp.ListenAndServe(":8080", router.HandleFastHTTP))
}

Given example will result in all routes of a subrouter being available under paths prefixed with a mount path.
