action-npm-publish

Description

Pass your token to the action:

name: Publish to npm

    types: [closed]

jobs:
  cache-build:
    permissions:
      contents: write
    if: |
      github.event.pull_request.merged == true &&
      startsWith(github.event.pull_request.head.ref, 'release/')
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Get Node.js version
        id: nvm
        run: echo ::set-output name=NODE_VERSION::$(cat .nvmrc)
      - uses: actions/setup-node@v2
        with:
          node-version: ${{ steps.nvm.outputs.NODE_VERSION }}
      - run: |
          yarn setup
          yarn build
      - uses: actions/cache@v2
        id: restore-build
        with:
          path: ./*

    steps:
