There is nothing stopping node from running on mobile and IIRC quite a few apps embed it as a part of electron or similar frameworks.

If i understand correctly bare can instead use much smaller engines like quickjs (and maybe libjs), but I'm not sure how the stdlib situation is for those.

Bare supports both QuickJS (https://github.com/holepunchto/libqjs) and JerryScript (https://github.com/holepunchto/libjerry), yes, allowing it to run on much more constrained devices than what Node.js is capable of. I'm running it on my MediaTek-based LTE router, for example, using JerryScript.
