This issue has been added to the FEAScript roadmap for the upcoming 0.2.0 release (https://github.com/orgs/FEAScript/discussions/17).

I created a branch that makes the package publishable on npm and compatible with generating types for dynamic suggestions.

FEAScript is now available as an npm package: https://www.npmjs.com/package/feascript
Thanks @sridhar-mani
