Well, you can provide in your environment all the binaries needed: - Java stuff - node and npm - I don't know what you would need for Postgres extensions - Python, pip or poetry (or whatever you use for Python package management) Here is an example flake: https://bpa.st/ZUQQ https://bpa.st/ZUQQ Under `devShells`, you have `packages`. You can put there any package from nixpkgs, not just Python packages like I have there. To make it cleaner, you could have a variable for each platform and concatenate them under packages like `packages = javaPkgs ++ nodePkgs ++ pgPkgs ++ pyPkgs`.
