| 
 | |
| This action provides the following functionality for GitHub Actions users:
 | |
| 
 | |
| - Optionally downloading and caching distribution of the requested Node.js version, and adding it to the PATH
 | |
| - Optionally caching npm/yarn/pnpm dependencies
 | |
| - Registering problem matchers for error output
 | |
| - Configuring authentication for GPR or npm
 | |
| 
 | |
| ## Usage
 | |
| 
 | |
| See [action.yml](action.yml)
 | |
| 
 | |
| **Basic:**
 | |
| 
 | |
| ```yaml
 | |
| steps:
 | |
| - uses: actions/checkout@v3
 | |
| - uses: actions/setup-node@v3
 | |
|   with:
 | |
|     node-version: 14
 | |
| - run: npm ci
 | |
| - run: npm test
 | |
| ```
 | |
| 
 | |
| The `node-version` input is optional. If not supplied, the node version from PATH will be used. However, it is recommended to always specify Node.js version and don't rely on the system one.
 | |
| 
 | |
| The action will first check the local cache for a semver match. If unable to find a specific version in the cache, the action will attempt to download a version of Node.js. It will pull LTS versions from [node-versions releases](https://github.com/actions/node-versions/releases) and on miss or failure will fall back to the previous behavior of downloading directly from [node dist](https://nodejs.org/dist/).
 | |
| 
 | |
| For information regarding locally cached versions of Node.js on GitHub hosted runners, check out [GitHub Actions Virtual Environments](https://github.com/actions/virtual-environments).
 | |
| 
 | |
| ### Supported version syntax
 | |
| 
 | |
| The `node-version` input supports the following values:
 | |
| 
 | |
|  - Major versions: `12`, `14`, `16`
 | |
|  - More specific versions: `10.15`, `14.2.0`, `16.3.0`
 | |
|  - NVM LTS syntax: `lts/erbium`, `lts/fermium`, `lts/*`
 | |
|  - Latest release: `latest`/`current`/`node`
 | |
| 
 | |
| **Note:** Since the latest release will not be cached always, there is possibility of hitting rate limit when downloading from dist
 | |
| 
 | |
| ### Checking in lockfiles
 | |
| 
 | |
| It's **always** recommended to commit the lockfile of your package manager for security and performance reasons. For more information consult the "Working with lockfiles" section of the [Advanced usage](docs/advanced-usage.md#working-with-lockfiles) guide.
 | |
| 
 | |
| ## Caching global packages data
 | |
| 
 | |
| The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under the hood for caching global packages data but requires less configuration settings. Supported package managers are `npm`, `yarn`, `pnpm` (v6.10+). The `cache` input is optional, and caching is turned off by default.
 | |
| 
 | |
| The action defaults to search for the dependency file (`package-lock.json` or `yarn.lock`) in the repository root, and uses its hash as a part of the cache key. Use `cache-dependency-path` for cases when multiple dependency files are used, or they are located in different subdirectories.
 | |
| 
 | |
| **Note:** The action does not cache `node_modules`
 | |
| 
 | |
| See the examples of using cache for `yarn`/`pnpm` and `cache-dependency-path` input in the [Advanced usage](docs/advanced-usage.md#caching-packages-data) guide.
 | |
| 
 | |
| **Caching npm dependencies:**
 | |
| 
 | |
| ```yaml
 | |
| steps:
 | |
| - uses: actions/checkout@v3
 | |
| - uses: actions/setup-node@v3
 | |
|   with:
 | |
|     node-version: 14
 | |
|     cache: 'npm'
 | |
| - run: npm ci
 | |
| - run: npm test
 | |
| ```
 | |
| 
 | |
| **Caching npm dependencies in monorepos:**
 | |
| 
 | |
| ```yaml
 | |
| steps:
 | |
| - uses: actions/checkout@v3
 | |
| - uses: actions/setup-node@v3
 | |
|   with:
 | |
|     node-version: 14
 | |
|     cache: 'npm'
 | |
|     cache-dependency-path: subdir/package-lock.json
 | |
| - run: npm ci
 | |
| - run: npm test
 | |
| ```
 | |
| 
 | |
| ## Matrix Testing
 | |
| 
 | |
| ```yaml
 | |
| jobs:
 | |
|   build:
 | |
|     runs-on: ubuntu-latest
 | |
|     strategy:
 | |
|       matrix:
 | |
|         node: [ 12, 14, 16 ]
 | |
|     name: Node ${{ matrix.node }} sample
 | |
|     steps:
 | |
|       - uses: actions/checkout@v3
 | |
|       - name: Setup node
 | |
|         uses: actions/setup-node@v3
 | |
|         with:
 | |
|           node-version: ${{ matrix.node }}
 | |
|       - run: npm ci
 | |
|       - run: npm test
 | |
| ```
