+# OCaml (JS)
+
+[OCaml](https://ocaml.org/) is an industrial-strength programming language supporting functional, imperative and object-oriented styles.
+
+LiveCodes runs the OCaml compiler itself, built with [js_of_ocaml](https://github.com/ocsigen/js_of_ocaml), so compilation happens in the browser and nothing is sent to a server. The compiler emits a JavaScript program, which the result page then runs.
+
+:::info Note
+
+LiveCodes also has an `ocaml` language, which runs the [ReScript](https://rescript-lang.org/) compiler. It is deprecated in favour of this one. Read documentation [here](./ocaml.mdx).
+
+:::
+
+## Demo
+
+import LiveCodes from '../../src/components/LiveCodes.tsx';
+
+export const params = {
+  'ocaml-js': 'let () =\n  print_endline "Hello, World!"\n',
+  console: 'full',
+};
+
+<LiveCodes params={params}></LiveCodes>
+
+## Usage
+
+LiveCodes runs OCaml in the browser, including the standard library.
+
+Because the compiled program *is* JavaScript by the time it runs, it can interact with the page. JavaScript interoperability and DOM access come from [js_of_ocaml](https://github.com/ocsigen/js_of_ocaml)'s `Js` and `Dom_html` with `open Js_of_ocaml` (see the [example below](#example-usage)).
+
+## Modules and Libraries
+
+The standard library is always available. Beyond it, these are linked on demand — the archive is fetched the first time a program names one of its modules, so a program that uses none of them downloads none of them.
+
+- **js_of_ocaml** — `Js`, `Dom_html`, and the rest of the browser APIs
+- **Str**, **Unix**, **Graphics** — from the OCaml distribution
+- **Lwt**, **js_of_ocaml-lwt** — promises and concurrency
+- **Re** — regular expressions
+- **jsonm**, **xmlm**, **uutf** — JSON, XML and Unicode text
+- **fmt**, **logs** — formatting and logging
+- **base64** — base64 encoding
+- **Zarith** — `Z` and `Q`, arbitrary-precision integers and rationals
+
+Everything here runs in the browser, so a library has to be pure OCaml, or have a JavaScript replacement for its C stubs — Zarith's are provided by `zarith_stubs_js`. Anything needing real threads, processes or a filesystem will not work, whatever is linked.
+
+This is the set built with the compiler. Other opam packages are not available.
+
+## Language Info
+
+### Name
+
+`ocaml-js`
+
+### Extensions
+
+`js.ocaml`, `js.ml`
+
+### Editor
+
+`script`
+
+## Compiler
+
+The OCaml compiler — the same `compiler-libs` frontend that compiles ordinary OCaml — compiled to JavaScript with [js_of_ocaml](https://github.com/ocsigen/js_of_ocaml). It is published as [@live-codes/ocaml](https://www.npmjs.com/package/@live-codes/ocaml).
+
+### Version
+
+`@live-codes/ocaml`: v0.2.0
+
+## Code Formatting
+
+Not supported.
+
+## Limitations
+
+There is no ppx support, since a ppx would have to run at compile time and compilation happens at run time here. So `##`, `##.` and `[%js]` are not available; use `Js.Unsafe` and the rest of the bindings instead.
+
+## Example Usage
+
+This example counts button clicks in the DOM, using `Dom_html`:
+
+<LiveCodes template="ocaml-js" height="80vh"></LiveCodes>
+
+## Starter Template
+
+https://livecodes.io/?template=ocaml-js
+
+## Links
+

+- [OCaml documentation](https://ocaml.org/docs/)
+- [@live-codes/ocaml on npm](https://www.npmjs.com/package/@live-codes/ocaml)

Subject: [PATCH 2/6] fix(ocaml-js): address review feedback

- drop unused compiler-esm re-export from barrel (avoids static pull-in)
- clear cached compiler promise on failed boot so a transient CDN error is retryable
- recommend rescript-ocaml, not the deprecated ocaml, in deprecation warning

Adds the ocamlJs language-info block (desc1, desc2, link, name) and the

localized text derived from each locale's existing ocaml entry.

Subject: [PATCH 5/6] fix(ocaml-js): keep app loading when deprecation warns in
 worker

The compile worker is created from a data: URL, which is not a valid base
for `new URL()`, so `getDocsUrl()` threw while building the deprecation
warning link. Because the OCaml deprecation predicate also matches the
canonical name `ocaml`, the warning now fires while the worker enumerates
languages, aborting its init message and leaving the app stuck on the
loading screen. Fall back to the configured relative docs path when the
base URL cannot be used.

The e2e test now selects the language by `data-lang`, since the dropdown
shows the long title ("OCaml (compiled to JavaScript)").

Subject: [PATCH 6/6] fix(ocaml-js): report compiler load/run failures as
 errors

Loading the compiler or running `compile()` can reject, and the page-side
handler did not catch it, so the compile request stayed pending. Return
the failure as a compilation error with empty output.
