Sounds like requirements Nix solves

  It helps but Nix just like Bazel can't handle Node.js in a cross-platform way. You still end up reverting to running `npm ci` in a Dockerfile and building the image in imperative style, giving up hermetic and reproducible builds in the process. The reason this is needed is node_modules contains platform specific native code. You can somewhat speed up cross-arch/OS builds by explicitly running the appropriate node-gyp incantation to rebuild the native components and skip entirely re-generating node_modules but that is still ultimately a bit gross. Compared to what you can achieve otherwise with Nix dockerTools.buildImage, Bazel docker_rules or Google's jib tool for JVM it's not even close to the same league in speed, reproducibility, convenience or maintenance overhead.
