so the easiest solution is every target has package.json files, refers to source deps elsewhere in the repo with relative paths, devs run “npm install && npm shrinkwrap” locally, check in npm-shrinkwrap.json for each target, and Pants works with those npm-shrinkwrap.json files (fixing their relative paths for source deps to whatever they need in .pants.d) before doing its own “npm install” in .pants.d
