package http_async

Http_async

HTTP 1.1 server for async applications.

Getting Started

This library isn't published to the opam repository yet so it requires pinning to the development version of dependencies.

opam pin add -n http_async.dev git+https://github.com/anuragsoni/http_async.git
opam install http_async

Hello World

open! Core
open! Async
open Http_async

let () =
  Command_unix.run
    (Server.run_command ~summary:"Hello world HTTP Server" (fun _request ->
       Service.respond_string "Hello World"))
;;

Routing?

Http_async doesn't ship with a router. There are multiple routing libraries available on opam and using Http_async with them should be fairly easy. As an example, integration with ocaml-dispatch can be done as so:

open! Core
open! Async
open Http_async

let routes =
  let open Dispatch in
  DSL.create
    [ ( "/hello/:name"
      , fun params _rest ->
          let name = List.Assoc.find_exn params ~equal:String.equal "name" in
          Service.respond_string (sprintf "Hello, %s" name) )
    ; ("/", fun _params _rest -> Service.respond_string "Hello World")
    ]
;;

let service request =
  let path = Service.resource request in
  match Dispatch.dispatch routes path with
  | Some response -> response
  | None -> Service.respond_string ~status:`Not_found "Route not found"
;;

let () = Command_unix.run (Server.run_command ~summary:"Hello world HTTP Server" service)
