OCaml JSX for ReasonReact.

ppx_bsx depends on ppx_lib, which means that ppx_bsx doesn't support bs-platform 5.x, so first step is configuring your project to "bs-platform": "^6.0.1".

Install ppx_bsx with opam or esy, and add ppx_bsx executable to bs-config.json:

{
  "ppx-flags": [
    "./_opam/bin/ppx_bsx",
    "./node_modules/bs-platform/lib/bsppx.exe -bs-jsx 3"
  ]
}

Replace ./_opam/bin/ppx_bsx to actual ppx_bsx installed path.

Example: https://github.com/cxa/ppx_bsx_example.

This is how it feel:

[%bsx "
<Container>
  <h1>Nice example</h1>
  <nav className="(styles "sidebar")">
    This is sidebar
  </nav>
  <div className="(styles "content")">
    "(React.string {j|这是主内容|j})"
  </div>
</Container>
"]

• Break [%bsx ""] into

  [%bsx "
  
  "]

  and ignore the first and last quotation marks.
• When you need OCaml expression, wrap it with double quotation marks, otherwise
• For string literal value, just use single quotation marks
• For single text node, you don't need to wrap it to ReasonReact.string, (surprisedly) <span>Hello, World</span> is accepted
• Single text {|你好|} (but not expr {|你好|}) will be transformed to {j|你好|j} automatically
