Cannot get TypeScript working

[letmaik]

I created a minimal example repro at https://github.com/letmaik/bug-repro-rollup-plugin-jscc

jscc doesn't seem to influence the output here.

Side question: in the rollup plugins, does jscc have to come before or after typescript? If it's before and asloader is true, then rollup throws an error about not understanding typescript syntax. If it's before and asloader is false, or if it's after the typescript plugin then no error is raised but no change in the output is seen.

I must be missing something extremely simple, but I triple-checked everything and just can't see it. Any help very welcome :)
