Bun Lockfile Detection Now Available

Vercel has extended its intelligent build skipping feature to support Bun package manager. When evaluating which projects in a monorepo need rebuilding, Vercel now reads Bun lockfiles to detect dependency changes—just as it does for npm, yarn, and pnpm.

How It Works

When you push changes to a monorepo, Vercel compares lockfile changes to determine if any dependencies have been updated. Projects with unchanged dependencies can now be safely skipped during the build process. This applies whether you're using Bun or other supported package managers.

Benefits

• Reduced build times: Projects without changes skip the build pipeline entirely
• Faster deployments: Teams see quicker deployment cycles across monorepos
• Better resource utilization: Fewer unnecessary builds mean less compute consumed
