Automating publishing Unity packages to npm registry

🎯 Why npmjs registry?

• Ready up to Open Source projects
• In-box GitHub Actions solution
• CLI support
• Allows tracking changes history via Unity Package Manager

1. Generate Access Token in npmjs registry
   

2. Select Access Token type
   

3. Add npm Access Token to GitHub repository secrets
   

4. Config GitHub workflow using a yml template as follows
   

name: npm

on:
  release:
    types: [published]

jobs:
  publish-npm:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      packages: write
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v3
        with:
          node-version: '20.x'
          registry-url: https://registry.npmjs.org
      - run: npm install --package-lock-only
      - run: npm ci
      - run: npm publish
        env:
          NODE_AUTH_TOKEN: ${{secrets.NPM_TOKEN}}
          GITHUB_TOKEN: ${{secrets.GITHUB_TOKEN}}

🎉 Now GitHub Actions will automatically upload package to npmjs registry
