Kevin Cui 6fed91f804 docs(README): point users to the successor pnpm/setup action (#282)
* docs(README): point users to the successor pnpm/setup action

The pnpm setup action has moved to `pnpm/setup`, which installs
pnpm v11+ as a self-contained native executable and can install a
JavaScript runtime (Node.js, Bun, or Deno) in the same step,
replacing `actions/setup-node`.

Add a notice at the top of the README, a migration section with a
before/after workflow example and an input/output mapping table,
and mention the successor in the Notes section. The rest of the
docs stay intact since `pnpm/action-setup` remains the way to
install pnpm v10 and older.

* docs(README): address review feedback on migration section

Add an explicit version: 11 to the migration example and note when the
input can be omitted, since pnpm/setup requires pnpm v11+ and a repo
migrating from version: 10 may have no packageManager field or one that
pins v10.

Move the v2 upgrade warning below the page title so the two callouts
are no longer adjacent blockquotes (markdownlint MD028), keeping the
successor notice and the legacy warning as separate blocks.

Fix the comma splice and use "set up" as the verb in the Notes
section.

# Setup pnpm
Install pnpm package manager.
> ## :warning: Upgrade from v2!
>
> The v2 version of this action [has stopped working](https://github.com/pnpm/action-setup/issues/135) with newer Node.js versions. Please, upgrade to the latest version to fix any issues.
## Migrating to pnpm/setup
[`pnpm/setup`](https://github.com/pnpm/setup) installs pnpm v11+ as a native standalone executable and can install Node.js, Bun, or Deno in the same step, so a typical workflow no longer needs `actions/setup-node` or an explicit `pnpm install` step:
```yaml
steps:
- uses: actions/checkout@v6
# Before:
# - uses: pnpm/action-setup@v6
# with:
# version: 10
# cache: true
# - uses: actions/setup-node@v4
# with:
# node-version: 22
# - run: pnpm install
# After:
- uses: pnpm/setup@v1
with:
version: 11
runtime: node@22
cache: true
```
The `version` input can be omitted only when `packageManager` (or `devEngines.packageManager`) in `package.json` declares pnpm v11 or newer; otherwise keep it explicit, since `pnpm/setup` requires pnpm v11+.
Input and output changes:
| `pnpm/action-setup` | `pnpm/setup` | Notes |
| ------------------- | ------------ | ----- |
| `version` | `version` | Must resolve to pnpm v11 or newer. As before, it can be omitted when `packageManager` (or `devEngines.packageManager`) is set in `package.json`. |
| `dest` | `dest` | Unchanged. |
| `run_install` | `install` | `pnpm/setup` runs `pnpm install` automatically when a `package.json` is present (`install: true` by default); set `install: false` to skip it. The object/array form (`recursive`, `cwd`, `args`) is not supported — run those commands in separate steps. |
| `cache` | `cache` | Unchanged. |
| `cache_dependency_path` | `cache-dependency-path` | Renamed to kebab-case. |
| `package_json_file` | `package-json-file` | Renamed to kebab-case. |
| `standalone` | removed | `pnpm/setup` always installs the standalone native executable. |
| n/a | `runtime` | New: installs Node.js, Bun, or Deno (e.g. `node@22`, `bun@latest`, `deno@2`), or reads `devEngines.runtime` from `package.json`. |
| n/a | `token` | New: GitHub token for release lookup; defaults to `${{ github.token }}` and rarely needs to be set. |
| `bin_dest` (output) | `bin-dest` (output) | Renamed to kebab-case. New outputs `runtime-name` and `runtime-version` describe the installed runtime. |
## 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 `10.9.8`), or a version range (such as `10`, `10.x.x`, `10.9.x`, `^10.9.8`, `*`, 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. `[--ignore-scripts, --strict-peer-dependencies]`.
### `cache`
**Optional** (_type:_ `boolean`, _default:_ `false`) Whether to cache the pnpm store directory.
### `cache_dependency_path`
**Optional** (_type:_ `string`, _default:_ `pnpm-lock.yaml`) File path to the pnpm lockfile, whose contents hash will be used as a cache key. Accepts multiple paths delimited by newlines.
### `package_json_file`
**Optional** (_type:_ `string`, _default:_ `package.json`) File path to the `package.json`/[`package.yaml`](https://github.com/pnpm/pnpm/pull/1799) 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@v6
with:
version: 10
```
### 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@v6
```
### Install pnpm and a few npm packages
```yaml
on:
- push
- pull_request
jobs:
install:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v6
- uses: pnpm/action-setup@v6
with:
version: 10
run_install: |
- recursive: true
args: [--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@v6
- uses: pnpm/action-setup@v6
name: Install pnpm
with:
version: 10
cache: true
- 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.
### Cache dependencies from multiple lockfiles
```yaml
on:
- push
- pull_request
jobs:
cache-and-install-multiple:
runs-on: ubuntu-latest
steps:
- name: Checkout
uses: actions/checkout@v6
- uses: pnpm/action-setup@v6
with:
version: 10
cache: true
cache_dependency_path: |
one/pnpm-lock.yaml
two/pnpm-lock.yaml
run_install: |
- cwd: one
- cwd: two
```
## Notes
This action does not set up Node.js. Use [actions/setup-node](https://github.com/actions/setup-node) yourself. If you are on pnpm v11 or newer, [`pnpm/setup`](https://github.com/pnpm/setup) can install pnpm and Node.js in a single step.
