This comes at the perfect time, I've wasted the last two days getting some TypeScript libraries build configuration to work with Rollup[0][1] ... this seems like the perfect time to de-duplicate with some configuration. Do you plan to also include something like TypeDoc[2][3] for generated documentation, which I'd argue would be pretty much required for libraries?
