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-beta

A beta release which adds reliability for pulling node distributions from a cache of node releases is available by referencing the v2-beta tag.

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2-beta
  with:
    node-version: '12'

It 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. It will pull LTS versions from main branch of node-versions repository and on miss or failure, it will fall back to the previous behavior of download directly from node dist.

The node-version input is optional. If not supplied, node which is in your 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@v1
  with:
    node-version: '12'
- run: npm install
- run: npm test

Check latest version:

In basic example, without check-latest flag, the action tries to resolve version from local cache firstly and download only if it is not found. Local cache on image is updated with a couple of weeks latency.
check-latest flag forces the action to check if the cached version is the latest one. It reduces latency significantly but it is much more likely to incur version downloading.

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
  with:
    node-version: '12'
    check-latest: true
- run: npm install
- run: npm test

Matrix Testing:

jobs:
  build:
    runs-on: ubuntu-16.04
    strategy:
      matrix:
        node: [ '10', '12' ]
    name: Node ${{ matrix.node }} sample
    steps:
      - uses: actions/checkout@v2
      - name: Setup node
        uses: actions/setup-node@v1
        with:
          node-version: ${{ matrix.node }}
      - run: npm install
      - run: npm test

Publish to npmjs and GPR with npm:

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v1
  with:
    node-version: '10.x'
    registry-url: 'https://registry.npmjs.org'
- run: npm install
- run: npm publish
  env:
    NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}
- uses: actions/setup-node@v1
  with:
    registry-url: 'https://npm.pkg.github.com'
- run: npm publish
  env:
    NODE_AUTH_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Publish to npmjs and GPR with yarn:

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v1
  with:
    node-version: '10.x'
    registry-url: <registry url>
- run: yarn install
- run: yarn publish
  env:
    NODE_AUTH_TOKEN: ${{ secrets.YARN_TOKEN }}
- uses: actions/setup-node@v1
  with:
    registry-url: 'https://npm.pkg.github.com'
- run: yarn publish
  env:
    NODE_AUTH_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Use private packages:

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v1
  with:
    node-version: '10.x'
    registry-url: 'https://registry.npmjs.org'
# Skip post-install scripts here, as a malicious
# script could steal NODE_AUTH_TOKEN.
- run: npm install --ignore-scripts
  env:
    NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}
# `npm rebuild` will run all those post-install scripts for us.
- run: npm rebuild && npm run prepare --if-present
