This action provides the following functionality for GitHub Actions runners:
- Optionally downloading and caching distribution of the requested Node.js version, and adding it to the PATH
- Optionally caching npm/yarn 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@v2
- uses: actions/setup-node@v2
with:
node-version: '14'
- run: npm install
- run: npm test
```
The `node-version` input is optional. If not supplied, the node version from PATH will be used. However, this action will still register problem matchers and support auth features. So setting up the node environment is still a valid scenario without downloading and caching versions.
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).
### Caching packages dependencies
The action has a built-in functionality for caching and restoring npm/yarn dependencies. Supported package managers are `npm`, `yarn`. The `cache` input is optional, and caching is turned off by default.
```yaml
steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
with:
node-version: '14'
cache: 'npm'
- run: npm install
- run: npm test
```
**Caching yarn dependencies:**
```yaml
steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
with:
node-version: '14'
cache: 'yarn'
- run: npm install
- run: npm test
```
Yarn caching handles both yarn versions: 1 or 2.
> At the moment, only `lock` files in the project root are supported.
### Matrix Testing:
```yaml
jobs:
build:
runs-on: ubuntu-latest
strategy:
matrix:
node: [ '12', '14' ]
name: Node ${{ matrix.node }} sample
steps:
- uses: actions/checkout@v2
- name: Setup node
uses: actions/setup-node@v2
with:
node-version: ${{ matrix.node }}
- run: npm install
- run: npm test
```
