pnpm is now fully supported by dependency graph, Dependabot alerts, and Dependabot security updates! If you manage your Node.js dependencies with the pnpm package manager, you can now receive and fix alerts about security vulnerabilities in those dependencies. To use this, enable Dependabot Security Updates from the repository settings page on the code security and analysis tab.
