Add TypeScript types for helpers

**Feature request**
It would be great to have export for config.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_export` with default `false`.

The issue names TypeScript helper types and a new config option, but does not identify files, tests, or an entry point. Start by locating the helper type definitions and config handling, then confirm how exporting config should work and verify that enable_export defaults to false.
