It doesn't work when there is no default exported

Tried on multiple versions of Node.js from 16 to 20. None of them worked. Did some debugging. Looks like the promise of the dynamic import never resolves. The process just hangs up there. But in fairness there are a lot of hang up issues reported for deasync, so probably it's the fault of that one.

But I've also tried the solution with execSync('sleep 1'), got very similar result. As long as Node.js was stuck in the loop, the code could never get into the .then(...) part of the import(). Looks like execSync is really sync after all, meaning the promise hasn't got a chance to ever resolve. Removing the while loop lets the promise to fulfil. Only issue is that in that case by the time the promise resolves everything else is completed, even the code that wanted to use the imported module.

I just cannot understand how you managed to get that one to work...?

I guess all is in the title :-)
