setup-node

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

Basic:

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, 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 and on miss or failure will fall back to the previous behavior of downloading directly from node dist.

For information regarding locally cached versions of Node.js on GitHub hosted runners, check out GitHub Actions Virtual Environments.

Supported version syntax

The node-version input supports the following syntax:

major versions: 12, 14, 16
more specific versions: 10.15, 14.2.0, 16.3.0
nvm lts syntax: lts/erbium, lts/fermium, lts/*

Caching packages dependencies

The action has a built-in functionality for caching and restoring npm/yarn dependencies. Supported package managers are npm, yarn, pnpm. The cache input is optional, and caching is turned off by default.

Caching npm dependencies:

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:

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

Yarn caching handles both yarn versions: 1 or 2.

Caching pnpm (v6.10+) dependencies:

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.

# NOTE: pnpm caching support requires pnpm version >= 6.10.0

steps:
- uses: actions/checkout@v2
- uses: pnpm/action-setup@646cdf48217256a3d0b80361c5a50727664284f2
  with:
    version: 6.10.0
- uses: actions/setup-node@v2
  with:
    node-version: '14'
    cache: 'pnpm'
- run: pnpm install
- run: pnpm test

At the moment, only lock files in the project root are supported.

Matrix Testing:

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node: [ '12', '14', '16' ]
    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
