yarn dlx: Run a Package Once

yarn dlx fetches and runs a package without adding it to the project.

dlx is the Berry replacement for npx, isolating the tool so it never pollutes your dependencies.

Common usage

• yarn dlx <pkg> [args]
• yarn dlx -p <pkg> <cmd> - different bin name
• pin: yarn dlx <pkg>@<version>

Example in CI

Run a scaffolding tool once.

yarn dlx create-vite@latest my-app

In CI

Pin the version for reproducibility. For repeated use, add it as a devDependency instead of fetching every run.

Key takeaways

• yarn dlx is Berry’s npx.
• Pin versions in CI.
• Add frequent tools as devDependencies.
