SYNOPSIS

bunx [options] package [arguments]

bunx auto-installs and runs executables from npm packages. It's Bun's equivalent of npx, roughly 100x faster for locally installed packages due to Bun's fast startup times.Packages not found in local node_modules are automatically installed into a global shared cache.

PARAMETERS

-p, --package name

Specify package when binary name differs

--bun

Force running with Bun instead of Node.js

-c, --config file

Specify bunfig.toml config file

--silent

Suppress output

BEHAVIOR

By default, bunx respects #!/usr/bin/env node shebangs in scripts. Use --bun to override and run with Bun runtime.

WINDOWS

On Windows, bunx uses a special .bunx file format for cross-filesystem symlinks that works with both Bun and Node.js.

CAVEATS

Packages are cached globally after first use. Use --bun flag when you specifically need Bun's runtime features. Some packages may expect Node.js-specific APIs.
