“With software program packages, we’ve got lockfiles, pinned hashes, and reproducible builds. With IDE [integrated development environment] extensions, we’ve got nearly nothing. There isn’t a integrity verification, no equal of package-lock.json, and most organizations haven’t any coverage by any means governing what builders are allowed to put in into their IDEs.”
