joeldenning/js-correct-lockfile

js-correct-lockfile is a tool for JavaScript projects that automates the verification of lockfile consistency in incoming pull requests, ensuring contributors use the correct package manager (npm, yarn, or pnpm) for the project. It is intended for open source maintainers and development teams who want to prevent the accidental inclusion of incorrect lockfiles, such as a yarn project inadvertently receiving an npm package-lock.json. The tool can be used via CLI, as a package.json script, or as a JavaScript module, and integrates seamlessly into CI workflows.
