And answer turned out to be possbile! Install upm globally. The scripts check for Node.js 22.3+, then install upm with npm. Then install your project's dependencies: Commit upm.lock with your package.json. When switching to upm, delete the old nodemodules first. Otherwise, your code may still import old packages. Use --dir to choose a project directory. Otherwise, install commands look for the nearest package.json above the current directory, or the workspace root that lists it. --dir uses the directory you give it; for a workspace tree, point it at the root and use -w where supported. Most commands support --json for machine-readable results. Progress…
