Render HTML with JSX

html_of_jsx is a JSX transformation and a library to write HTML 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 API
  • JSX.render to render a JSX element to a HTML string
  • Helper functions to construct DOM nodes: JSX.string, JSX.int, JSX.float, JSX.null, JSX.list, JSX.array, and JSX.unsafe
  • Advanced rendering: JSX.render_to_channel, JSX.render_streaming
• Designed to work on the server, but can be used on the client-side as well (with Melange or jsoo)
