# HostRouter

`hostrouter` is a small Go pkg to let you route traffic to different http handlers or routers

based on the request host. This is useful to mount multiple routers on a single server.

## Basic usage example

```go

//...

func main() {

  r := chi.NewRouter()

  r.Use(middleware.RequestID)

  r.Use(middleware.RealIP)

  r.Use(middleware.Logger)

  r.Use(middleware.Recoverer)

  hr := hostrouter.New()

  // Requests to api.domain.com

  hr.Map("", apiRouter()) // default

  hr.Map("api.domain.com", apiRouter())

  // Requests to doma.in

  hr.Map("doma.in", shortUrlRouter())

  // Requests to *.doma.in

  hr.Map("*.doma.in", shortUrlRouter())

  // Requests to host that isn't defined above

  hr.Map("*", everythingElseRouter())

  // Mount the host router

  r.Mount("/", hr)

  http.ListenAndServe(":3333", r)

}

// Router for the API service

func apiRouter() chi.Router {

  r := chi.NewRouter()

  r.Get("/", apiIndexHandler)

  // ...

  return r

}

// Router for the Short URL service

func shortUrlRouter() chi.Router {

  r := chi.NewRouter()

  r.Get("/", shortIndexHandler)

  // ...

  return r

}

```
