setup-node

This action sets by node environment for use in actions by:

• optionally downloading and caching a version of node - npm by version spec and add to PATH
• registering problem matchers for error output
• configuring authentication for GPR or npm

v2

This release adds reliability for pulling node distributions from a cache of node releases.

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
  with:
    node-version: '14'

The action will first check the local cache for a semver match. The hosted images have been updated with the latest of each LTS from v8, v10, v12, and v14. self-hosted machines will benefit from the cache as well only downloading once. The action will pull LTS versions from node-versions releases and on miss or failure will fall back to the previous behavior of downloading directly from node dist.

The node-version input is optional. If not supplied, the node version that is 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.

Usage

See action.yml

Basic:

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
  with:
    node-version: '14'
- run: npm install
- run: npm test

Check latest version:

In the basic example above, the check-latest flag defaults to false. When set to false, the action tries to first resolve a version of node from the local cache. For information regarding locally cached versions of Node on GitHub hosted runners, check out GitHub Actions Virtual Environments. The local version of Node in cache gets updated every couple of weeks. If unable to find a specific version in the cache, the action will then attempt to download a version of Node. Use the default or set check-latest to false if you prefer stability and if you want to ensure a specific version of Node is always used.

If check-latest is set to true, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, a version of Node will then be downloaded. Set check-latest to true it you want the most up-to-date version of Node to always be used.

Setting check-latest to true has performance implications as downloading versions of Node is slower than using cached versions

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
  with:
    node-version: '14'
    check-latest: true
- run: npm install
- run: npm test

Matrix Testing:

jobs:
  build:
    runs-on: ubuntu-16.04
    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

Architecture:

You can use any of the supported operating systems, and the compatible architecture can be selected using architecture. Values are x86, x64, arm64, armv6l, armv7l, ppc64le, s390x (not all of the architectures are available on all platforms).

When using architecture, node-version must be provided as well.

jobs:
  build:
    runs-on: windows-latest
    name: Node sample
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-node@v2
        with:
          node-version: '14'
          architecture: 'x64' # optional, x64 or x86. If not specified, x64 will be used by default
      - run: npm install
      - run: npm test

          - 12
          - 14
        architecture:
          - x64
        # an extra windows-x86 run:
        include:

            node_version: 12
            architecture: x86
