My question is about the implementation. Are you running a Node.js executable in a Docker-style container for each of these? Or are you attempting to achieve the constraints that containers provide at a higher level of abstraction? How do you restrict access to network, disk, excessive RAM, and excessive CPU in a high level JavaScript container — is there an actual JavaScript runtime that supports constraining all of those? I also wonder about applications where WebAssembly isn't the most performant thing — image resizing, one of your examples, is also an example of a situation where you get significantly better performance with SIMD instructions. The experiment was tried here: https://www.libvips.org/2020/09/01/libvips-for-webassembly.html https://www.libvips.org/2020/09/01/libvips-for-webassembly.h...
