Action — setup-node

Installs Node.js and the correct package manager (pnpm or bun), restoring the appropriate dependency cache. Auto-detects the package manager from the lockfile.

Usage

steps:
  - uses: actions/checkout@v4

  - uses: KevinDeBenedetti/github-workflows/.github/actions/setup-node@main
    with:
      node-version: '20'

Inputs

Input	Type	Default	Description
node-version	string	'20'	Node.js version to install
working-directory	string	'.'	Directory to look for lockfile and run install
package-manager	string	auto	pnpm | bun | auto — auto-detects from lockfile
install	boolean	true	Run install after setup

Outputs

Output	Description
package-manager	Resolved package manager (pnpm or bun)
cache-hit	Whether the package cache was restored

Steps

1. Resolve package manager (bun.lockb / bun.lock → bun, otherwise → pnpm)
2. Setup pnpm or bun (with Node.js)
3. Restore cache (pnpm store or ~/.bun/install/cache)
4. Install dependencies (--frozen-lockfile)

Notes

• install: 'false' skips the install step — useful when you only need the toolchain and want to restore a build cache before installing.
• The package-manager output can be used in subsequent steps to conditionally run pnpm or bun commands.
