Setup pnpm

Install pnpm package manager.

Inputs

version

Version of pnpm to install.

Optional when there is a packageManager field in the package.json.

otherwise, this field is required It supports npm versioning scheme, it could be an exact version (such as 6.24.1), or a version range (such as 6, 6.x.x, 6.24.x, ^6.24.1, *, etc.), or latest.

dest

Optional Where to store pnpm files.

run_install

Optional (default: null) If specified, run pnpm install.

If run_install is either null or false, pnpm will not install any npm package.

If run_install is true, pnpm will install dependencies recursively.

If run_install is a YAML string representation of either an object or an array, pnpm will execute every install commands.

run_install.recursive

Optional (type: boolean, default: false) Whether to use pnpm recursive install.

run_install.cwd

Optional (type: string) Working directory when run pnpm [recursive] install.

run_install.args

Optional (type: string[]) Additional arguments after pnpm [recursive] install, e.g. [--frozen-lockfile, --strict-peer-dependencies].

package_json_file

Optional (type: string, default: package.json) File path to the package.json to read "packageManager" configuration.

standalone

Optional (type: boolean, default: false) When set to true, @pnpm/exe, which is a Node.js bundled package, will be installed, enabling using pnpm without Node.js.

This is useful when you want to use a incompatible pair of Node.js and pnpm.

Outputs

dest

Expanded path of inputs#dest.

bin_dest

Location of pnpm and pnpx command.

Usage example

Install only pnpm without packageManager

This works when the repo either doesn't have a package.json or has a package.json but it doesn't specify packageManager.

on:
  - push
  - pull_request

jobs:
  install:
    runs-on: ubuntu-latest

    steps:
      - uses: step-security/action-setup@v4
        with:
          version: 9

Install only pnpm with packageManager

Omit version input to use the version in the packageManager field in the package.json.

on:
  - push
  - pull_request

jobs:
  install:
    runs-on: ubuntu-latest

    steps:
      - uses: step-security/action-setup@v4

Install pnpm and a few npm packages

on:
  - push
  - pull_request

jobs:
  install:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - uses: step-security/action-setup@v4
        with:
          version: 9
          run_install: |
            - recursive: true
              args: [--frozen-lockfile, --strict-peer-dependencies]
            - args: [--global, gulp, prettier, typescript]

Use cache to reduce installation time

on:
  - push
  - pull_request

jobs:
  cache-and-install:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - uses: step-security/action-setup@v4
        name: Install pnpm
        with:
          version: 9
          run_install: false

      - name: Install Node.js
        uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: 'pnpm'

      - name: Install dependencies
        run: pnpm install

Note: You don't need to run pnpm store prune at the end; post-action has already taken care of that.

Notes

This action does not setup Node.js for you, use actions/setup-node yourself.
