For something which works across all JS runtimes (Deno, Node) and achieves basically the same, check out the popular JS library Execa[1]. Works like a charm!
Another alternative is the ZX shell[2] JS library. Tho haven't tested it.

Which bun also acknowledges here:

I suppose one significant difference is that bun reimplements shell built-ins. I believe that zx simply executes bash or powershell and fails if neither is available.
Although according to the linked issue, it has been "fixed", I still ran into a problem during a batch script that was calling imagemagick through a shell for each file in a massive directory; profiling was telling me that starting (not completing) (yes, I was using the async version) the child process increasingly slows, from sub-millisecond for the first few spawns, to eventually hundreds of milliseconds or seconds... Eventually I had to resort to doing only single spawn of a bash script that in turn did all the shelling out.
It seems that the linked execa still relies on child_process and therefore has the same issue. It saddens me to see the only package for node that appears to actually fix this and provide a workaround seems to be https://github.com/TritonDataCenter/node-spawn-async and unmaintained.
