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.

I’m using zx and the API seems very similar to what is described in the post. Which bun also acknowledges here: https://github.com/oven-sh/bun/blob/main/docs/runtime/shell.md https://github.com/oven-sh/bun/blob/main/docs/runtime/shell.... 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.

One thing that surprised me about Node was how slow the default way to shelling out (child_process) could be (probably https://github.com/nodejs/node/issues/14917 https://github.com/nodejs/node/issues/14917). 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 https://github.com/TritonDataCenter/node-spawn-async and unmaintained.

  I worked on that Node.js issue. If you can share a repro, I'd love to take a look: https://github.com/nodejs/node/issues/new?assignees=&labels=&projects=&template=1-bug-report.yml https://github.com/nodejs/node/issues/new?assignees=&labels=...

    That's very kind of you - I tried making a dead-simple repro just now with Node 20, and it seemed to run without the problem. I'll try reproducing it in a bit with my original use case of imagemagick and see if the issue still exists.

For Deno there is https://github.com/dsherret/dax https://github.com/dsherret/dax which is also zx inspired and has a cross platform shell built-in.
