yarn 1.x treats peer dependencies as optional dependencies; it does not automatically install them, and just produce a warning if they are missing. this is what used to be the behaviour of npm as well. I don't know if newer Yarn versions have changed this

perhaps there are circular plugin architecures, but usually it's more something like

const thing = require("thing");
const thingPluginA = require("thing-plugin-a);
const thingPluginB = require("thing-plugin-b");

let instance = thing({ plugins: thingPluginA, thingPluginB });

and so both the "core" package and the plugin packages are loaded from the application code, the plugins don't load the core and the core doesn't load the plugins, the peer dependency constraint just serves to give people a warning if they have an incompatible core and plugins in the same project

I wonder if it's possible to just install a list of dependencies https://github.com/svanderburg/node2nix#adding-unspecified-dependencies , like having a package.json

npm update doesn't work so I think not. My original issue is that right now I need to use export NODE_PATH="${pulumiSdks}/lib/node_modules/PKG_NAME/lib/modules" while my package has 0 source code, it's just a compilation of dependencies (same package.json as my original)

It's funny how no one seems to be using typescript https://www.reddit.com/r/Nix/comments/x7tdxd/building_typescript_node_apps_with_nix/ https://www.reddit.com/r/NixOS/comments/16xlbk2/looking_for_help_to_use_nixos_in_a_typescript/

think I kinda managed to package my typescript program with buildNpmPackage but on run I get

$ jkops --help

usually I can manage this kind of issues with a bit of NODE_PATH shenaningan but the files dont seem to even exist in fd -uL dist-cjs/index.js /nix/store/z4dmxdr8v12cy6fzk723f0p9gyr7rxi4-jkops-1.0.0/. I can share the package{-lock}.json if it helps.
