opium

You may have meant this post: https://discuss.ocaml.org/t/excited-about-dream-web-framewor... or another in that thread, as the specific one linked doesn't compare Dream with Opium! Opium itself is found here: https://github.com/rgrinberg/opium

Lwt [1] based web frameworks can be used on MirageOS if they provide an interface that allows someone to swap out the unix dependent pieces. One such framework is Opium [2], that provides most of its features in a unix independent code library `opium_kernel`. Its fairly straightforward to run an opium app on mirage. This example needs to be updated to the newest apis in the released version of Opium but this can provide some hints about how to run an opium app on mirage: https://github.com/anuragsoni/ocaml-opium-unikernel. If a lower level web toolkit is sufficient then ocaml's cohttp [3] library has been available on mirage for quite some time now.

There is some good work going on for the lower level pieces: https://github.com/anmonteiro/ocaml-h2 - HTTP2 stack https://github.com/inhabitedtype/httpaf - HTTP stack For micro-frameworks there are a few options available like https://github.com/rgrinberg/opium https://github.com/ostera/httpkit There are some scattered pieces in the ecosystem for routing, sessions etc but i agree that compared to Python, JS, etc the ecosystem might not look as cohesive or expansive for web applications. So there should definitely be room to have new solutions in this space

Server side reason can already compile to native binaries (thanks to the OCaml compiler). While maybe smaller than the npm ecosystem there are a lot of high quality packages available on the OCaml ecosystem [1] that allow for a very pleasant server side development experience. For example https://github.com/rgrinberg/opium is a really nice high level toolkit. There are database bindings to Postgres, Mysql and the like, and high level interfaces to them like https://github.com/paurkedal/ocaml-caqti [1] http://opam.ocaml.org/packages/

You could look at these: https://github.com/rgrinberg/opium https://github.com/inhabitedtype/ocaml-webmachine https://github.com/inhabitedtype/ocaml-session https://github.com/arenadotio/pgx (there are a few other as well, not sure which one would support PostGIS) https://github.com/Leonidas-from-XIV/slacko When in doubt head over to https://discuss.ocaml.org/ and show an example if you run into any trouble.

There is Ocsigen (https://en.wikipedia.org/wiki/Ocsigen) which lets you write OCaml on the front-end and back-end, and is a fully-featured self-contained server. There is also Opium (https://github.com/rgrinberg/opium) which is a Sinatra-like light-weight web server. Neither has the kind of vast community support like Rails or Django enjoys, and I haven't used them in anger either.

Scheme and OCaml don't have that much in common really (unless you mean derivatives like typed racket, but even then). OWebl, in spite of its shiny website, is not what I would call "popular". You want to look at opium[1] or ocsigen/eliom [2]. Don't know what you have against OPAM, it's the best language-specific dependency manager I know. 1: https://github.com/rgrinberg/opium 2: http://ocsigen.org/eliom/

You have opium [1], which is considerably lighter and more traditional (no Eliom stuff). 1: https://github.com/rgrinberg/opium

If you want something cohttp based https://github.com/rgrinberg/opium might serve your needs.

Have you heard about Stog[1]? To complete your list there is also Opium[2], which is a very nice minimalistic web framework. Also there are some interesting web projects listed in Awesome OCaml list[3].

It is quite new compared to what others posted: https://github.com/rgrinberg/opium
