Support "build" mode (multi project) Typescript

[dardino]

Can we have a support for this?

It'd be great to support that but there could be some potential complications. I'll add this to our list of potential enhancements.

For reference, here is that information on the TypeScript website: https://www.typescriptlang.org/docs/handbook/project-references.html

I want to support this - but in order to move forward with it, I will need at least one example project using it... closing as unactionable for now. If someone has a project using this that isn't horrible to install, please open a new issue about this so that we can work through any remaining issues.
