# JavaScript API modules

Oro Runtime exposes native capabilities as explicit ES module imports under the
`oro:*` namespace. Treat those imports as the boundary between ordinary web code
and host capabilities.

Use this page when you need to find the right API family or confirm a public subpath import.

## Notes

- The authoritative surface is the runtime’s published TypeScript declarations.
- This page excludes private implementation families and bundled third-party shims that are not part of the supported
  application-facing API.
- If you know the module name, use the docs search box or open the matching family page from the sidebar.
