# Setup pnpm
Install pnpm package manager.
## Inputs
### `version`
Version of pnpm to install.
**Optional** when there is a [`packageManager` field in the `package.json`](https://nodejs.org/api/corepack.html).
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](https://www.npmjs.com/package/@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`.
```yaml
on:
- push
- pull_request
jobs:
install:
runs-on: ubuntu-latest
steps:
- uses: pnpm/action-setup@v4
with:
version: 8
```
### Install only pnpm with `packageManager`
Omit `version` input to use the version in the [`packageManager` field in the `package.json`](https://nodejs.org/api/corepack.html).
```yaml
on:
- push
- pull_request
jobs:
install:
runs-on: ubuntu-latest
steps:
- uses: pnpm/action-setup@v4
```
### Install pnpm and a few npm packages
```yaml
on:
- push
- pull_request
jobs:
install:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: pnpm/action-setup@v4
with:
version: 8
run_install: |
- recursive: true
args: [--frozen-lockfile, --strict-peer-dependencies]
- args: [--global, gulp, prettier, typescript]
```
### Use cache to reduce installation time
```yaml
on:
- push
- pull_request
jobs:
cache-and-install:
runs-on: ubuntu-latest
steps:
- name: Checkout
uses: actions/checkout@v4
- uses: pnpm/action-setup@v4
name: Install pnpm
with:
version: 8
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](https://github.com/actions/setup-node) yourself.
