how exactly is the typescript compile triggered?

Pulumi uses

ts-node

(https://www.npmjs.com/package/ts-node) by default to compile files on the fly as they are `require`d by Node.js. You can disable this - or just pre-compile your TypeScript to JavaScript and point at a JavaScript entrypoint. See https://www.pulumi.com/docs/intro/languages/javascript/#disabling-built-in-typescript-support.

Is there any way to further configure, e.g. a script in package.json?

I believe you would need to take over the compilation process yourself to support this. There is currently no way for

pulumi up

to invoke your build in this case though, so you would need separate "build" and "deploy" steps.

What exactly is the issue with referenced projects?

hmmm, any idea on how to get ts-node to handle referenced projects?

I’m not exactly clear on what aspect of Yarn workspace referenced projects doesn’t work. Do you have some manual build step somewhere? Vanilla use of yarn workspaces should work fine here.

TypeScript referenced projects (unrelated to yarn workspaces): https://www.typescriptlang.org/docs/handbook/project-references.html. This allow me tell a sub-project that it depends on e.g. the common module, and then tsc will make sure common is compiled and up-to-date if invoked as

tsc -b
