Add support for the http.apps config field in langgraph.json that lets
users mount multiple HTTP apps at different path prefixes alongside the
built-in LangGraph API.
Config format:
{
"http": {
"app": "./custom_routes.py:app",
"apps": {
"/dashboard": "./dashboard.py:app",
"/ext": "./extension.js:app",
"/conduit": "some-npm-package:app"
}
}
}
Changes:
- Add apps: dict[str, str] | None to HttpConfig TypedDict in schemas.py
- Add validation for http.apps entries (prefix must start with /, values
must be module:attribute format)
- Add _update_http_apps_paths() for Docker container path rewriting
- Add _is_js_http_app() and _has_js_http_apps() helpers for JS detection
- Ensure Node.js is installed in Docker images when JS HTTP apps present
- Regenerate JSON schema files
