@lutaml/lutaml-model

JavaScript release of lutaml-model, Opal-compiled and published as @lutaml/lutaml-model on npm.

Install

```sh npm install @lutaml/lutaml-model ```

Flavors

Entry	File	Use case
`lutaml-model` (default)	`dist/lutaml-model.js`	Self-contained — Opal runtime embedded. CDN-friendly.
`lutaml-model-no-opal`	`dist/lutaml-model-no-opal.js`	External — references `@lutaml/opal-runtime` global. For bundler users who share runtime.

XML adapters

Both pure-Ruby XML adapters from the Ruby gem ship in the bundle:

• Oga — default. Compiled from the vendored `opal-oga` fork, which provides a pure-Ruby lexer under `ext/pureruby/` selected via `RUBY_PLATFORM == 'opal'` in `lib/oga.rb`.
• REXML — opt-in via `Lutaml::Model::Config.xml_adapter_type = :rexml`. Compiled from the bundled stdlib gem, with moxml's `lib/compat/opal/rexml/*` shadows patching the parts Opal can't follow natively.

Nokogiri and Ox are stubbed (C extensions, no Opal equivalent).

Build note: OPAL_PREFORK_DISABLE=1

Opal 1.8.x defaults to its `Prefork` scheduler, which deadlocks on this gem's 516 autoloads. The build sets `OPAL_PREFORK_DISABLE=1` to select Opal's built-in `Sequential` scheduler (same one used under Windows or when running inside Opal itself).

Opal 2 master adds a `Threaded` scheduler as well. Once Opal 2 ships, the env var becomes unnecessary.

Sync model

This package is rebuilt automatically whenever the Ruby source changes:

Ruby event	Trigger	JS dist-tag
Tag push (stable release)	`repository_dispatch(do-release)` from lutaml-model's release chain	`latest`
Push to `main`	`repository_dispatch(js-sync-main)` from lutaml-model's `.github/workflows/js-sync.yml`	`next`
Pull request touching `lib/`	`repository_dispatch(js-pr-check)` from lutaml-model's `.github/workflows/js-pr-check.yml`	(no publish; smoke test only)

Install the latest dev build with:

```sh npm install @lutaml/lutaml-model@next ```

Source

Built from lutaml-model by its release workflow. The Ruby gem remains the single source of truth.
