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)
