This is a GitHub Actions to check package version before publish npm.

1. Running GitHub Action

   

2. Updated version of package.json and commit (if branch is not protected)

   

e.g. .github/workflows/check_version.yml

on: push
name: Check package version
jobs:
  checkVersion:
    name: Check package version
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

      # Use this GitHub Action
      - name: Check package version
        uses: technote-space/package-version-check-action@v1
        with:
          BRANCH_PREFIX: release/

e.g. .github/workflows/release.yml

on:
 push:
   tags:
     - 'v*'
name: Publish Package
jobs:
  release:
    name: Publish Package
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2

      # Use this GitHub Action
      - name: Check package version
        uses: technote-space/package-version-check-action@v1
        with:
          COMMIT_DISABLED: 1

      - name: Install Package dependencies
        run: yarn install
      - name: Build
        run: yarn build
      - name: Publish
        run: |
          npm config set //registry.npmjs.org/:_authToken=$NPM_AUTH_TOKEN
          npm publish
        env:
          NPM_AUTH_TOKEN: ${{ secrets.NPM_AUTH_TOKEN }}

More details of target event

• tags
  • semantic versioning tag (e.g. v1.2.3)
• branches
  • ${BRANCH_PREFIX}${tag}
    • tag: semantic versioning tag (e.g. v1.2.3)
    • e.g. branch: release/v1.2.3

• branches
  • ${BRANCH_PREFIX}${tag}
    • tag: semantic versioning tag (e.g. v1.2.3)
    • e.g. branch: release/v1.2.3

• tags
  • semantic versioning tag (e.g. v1.2.3)

If you forget to update the package.json version, publishing the npm package will fail.

If you are invoking an action by pushing a tag, you have to do following steps again.

1. Delete pushed tag
2. Update package.json version
3. Commit and tag again
4. Push

This is very troublesome.

This GitHub Action updates the version in package.json based on the tag name automatically.
So you don't have to worry about the version in package.json.

This action also commits the change if the branch is not protected.
If the branch is protected, this action just update the version in package.json.

Commit is valid when pushing to default branch with tag or branch starting with ${BRANCH_PREFIX}.

The GITHUB_TOKEN that is provided as a part of GitHub Actions doesn't have authorization to create any successive events.
So it won't spawn actions which triggered by push.

This can be a problem if you have branch protection configured.

If you want to trigger actions, use a personal access token instead.

1. Generate a personal access token with the public_repo or repo scope.
   (repo is required for private repositories).
2. Save as ACCESS_TOKEN
3. Add input to use ACCESS_TOKEN instead of GITHUB_TOKEN.
   e.g. .github/workflows/check_version.yml

   on: push
   name: Check package version
   jobs:
     checkVersion:
       name: Check package version
       runs-on: ubuntu-latest
       steps:
         - uses: actions/checkout@v2
   
         # Use this GitHub Action
         - name: Check package version
           uses: technote-space/package-version-check-action@v1
           with:
             GITHUB_TOKEN: ${{ secrets.ACCESS_TOKEN }}
             BRANCH_PREFIX: release/

Tag name format must be Semantic Versioning.
