Anecdotally, ESM has been an absolute nightmare. Packages that aren’t compatible without code changes, having to add extensions to every single import unless we specify a flag (that is now deprecated), challenges with import maps and module resolution, the list goes on.

So we just use CommonJS with project references and call it a day. Everything works and we don’t need to change any of our code. The way ESM was introduced into Node has been the dumbest decision. And they’re doubling down on it. Excited for Bun to be compatible with my project so that I never have to deal with any of this again.
