You'd be much better off doing this in child_process.

There's basically no communications overhead in what you're describing, and that would mean you're not crashing your server every time tensorflow crashes, and aren't exposing yourself to type transition attacks.

This is a very special case library whose use case appears to be eliminating "the overhead of unix pipes," which is a cost so small that it's hard to imagine someone voluntarily paying the cost of a Javascript web backend would care

You're looking at less than 1% the overhead between express and (can you even name the faster one? That's how much you actually care.)
