package vif

νιϝ, a small framework for building a web server from an OCaml script

(nu)(iota)(digamma)

disclaimer: Please note that this is an experimental project. It's also an opportunity to build something that can be satisfying for web development. However, we do not recommend using this project in production.

Vif is a small program that runs an OCaml script and launches a Web server from it. The main idea is to be able to set up a typed Web server as quickly as possible (note that we use hurl, an HTTP client in OCaml)

  let* () = Response.add ~field "text/html; charset=utf-8" in
  let* () = Response.with_string req "Hello World!" in
  Response.respond `OK
;;

let routes =
  let open Vif.Uri in
  let open Vif.Route in
  [ get (rel /?? nil) --> default ]

  Vif.run routes ()

Examples

The examples folder contains several examples of the use of vif. It shows the management of more complex requests (json, multipart-form, etc.) as well as the use of an SQL database with caqti.
