Render HTML with JSX

html_of_jsx is a JSX transformation and a library to write HTML declaratively in OCaml, Reason and mlx.

Features

  • Brings the "component model" to HTML
  • Supports all of the Reason's JSX features (uppercase components, fragments, optional attributes, punning)
  • but with a few improvements (lowercase components, no need to add the ppx annotation)
  • No React idioms (no className, no htmlFor, no onChange, etc...)
  • Integrates well with htmx
  • Type-safe, validates attributes and their types (it can be better thought)
  • Works with OCaml, Reason and mlx
  • Minimal

    • JSX.render to render a JSX element to a HTML string
    • JSX.* to construct DOM Elements and DOM nodes (JSX.string, JSX.int, JSX.null, JSX.list and JSX.unsafe)
  • Designed to work on the server, but can be used on the client-side as well (with Melange or jsoo)

opam install html_of_jsx
