Module SihlSource

Sihl is a high-level web application framework providing a set of composable building blocks and recipes that allow you to develop web apps quickly and sustainably. Statically typed functional programming with OCaml makes web development fun and safe.

Things like database migrations, HTTP routing, user management, sessions, logging, emailing, job queues and schedules are just a few of the topics Sihl takes care of.

Let's have a look at a tiny Sihl app in a file called sihl.ml:

  module Service = struct
    module WebServer = Sihl.Web.Server.Service.Opium
  end

  let hello_page =
    Sihl.Web.Route.get "/hello/" (fun _ ->
        Sihl.Web.Res.(html |> set_body "Hello!") |> Lwt.return)
  ;;

  let endpoints = [ "/page", [ hello_page ], [] ]
  let services = [ Service.WebServer.configure endpoints [ "PORT", "8080" ] ]
  let () = Sihl.Core.App.(empty |> with_services services |> run)
