semantic-release shareable config to publish to npm and/or ghcr.

now available as a GitHub Marketplace action

📦 Plugins

This shareable configuration use the following plugins:

• @semantic-release/commit-analyzer
• @semantic-release/release-notes-generator
• @semantic-release/changelog
• conventional-changelog-conventionalcommits
• @semantic-release/npm
• semantic-release-replace-plugin
• @semantic-release/git
• @semantic-release/github
• @eclass/semantic-release-docker
• @semantic-release/exec
• semantic-release-major-tag
• npmlog

🖥️ Requirements

Most important limitations are:

• GITHUB_TOKEN for everything
• NPM_TOKEN for public npm library
• docker containers need to be built beforehand

You can skip here if you are using elevated Private Access Token, however we don't recommend going down that path.

No force push or admin cherries branch protections for the following branches:

• main - required
• next - optional, next channel
• next-major - optional, next major
• alpha - optional, pre-release branch
• beta - optional, pre-release branch
• vX[.X.X] - maintenance releases

If you use more than the main branch, optionally create an environment that is limiting where pushes can come from and enable the merge strategy.

We are using production in our examples, if you copy paste them you will find this new environment generated in your settings! 🍕

🧪 GitHub actions usage

Since version 3 it is possible to use semantic-release without any trace of it or the open-sauced configuration anywhere in the dependency tree.

Docker containers are pushed as part of the release so they mirror the availability of npm packages.

The simplest use case for a typical NPM package, almost zero install downtime from ghcr and no more local tooling:

name: "Release container"

on:
  push:
    branches:
      - main
      - next
      - next-major
      - alpha
      - beta

jobs:
  release:
    environment:
      name: production
      url: https://github.com/${{ github.repository }}/releases/tag/${{ env.RELEASE_TAG }}
    runs-on: ubuntu-latest
    steps:
      - name: "☁️ checkout repository"
        uses: actions/checkout@v3
        with:
          fetch-depth: 0

      - name: "🚀 release"
        id: semantic-release
        uses: docker://ghcr.io/tmcb-space/release:1.0.0
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

      - name: '♻️ cleanup'
        run: |
          echo ${{ env.RELEASE_TAG }}
          echo ${{ env.RELEASE_VERSION }}

Marketplace actions should default to the major tag and are essentially more stable as we have to curate every release.

A more traditional approach, only thing really different here is a minor pull overhead and using set outputs instead of environment variables:

name: "Release"

on:
  push:
    branches:
      - main
      - next
      - next-major
      - alpha
      - beta

jobs:
  release:
    environment:
      name: production
      url: https://github.com/${{ github.repository }}/releases/tag/${{ steps.semantic-release.outputs.release-tag }}
    name: Semantic release
    runs-on: ubuntu-latest
    steps:
      - name: "☁️ checkout repository"
        uses: actions/checkout@v3
        with:
          fetch-depth: 0

      - name: "🚀 release"
        id: semantic-release
        uses: TMCB-SPACE/release@v1
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

      - name: '♻️ cleanup'
        run: |
          echo ${{ steps.semantic-release.outputs.release-tag }}
          echo ${{ steps.semantic-release.outputs.release-version }}

📦 NPM usage

You can opt to use this package in your local tooling. Proceed as you would normally would, replacing npm with your package manager of choice and install the package:

npm install --save-dev release

The shareable config can then be configured in the semantic-release configuration file:

{
  "extends": "release"
}

Now all you need to do is create a release:

npx semantic-release

🔧 Configuration

See each plugin documentation for required installation and configuration steps.

NPM

Set private to true in package.json if you want to disable npm, or, change the scope of package using publishConfig.

Keep one of files or main keys in your package.json accurate depending on whether you are building a library or an application.

If you publish, make sure to also provide a valid NPM_TOKEN as .npmrc authentication is ignored in our config!

GitHub Actions

Unless you have an action.yml present in your root folder, this module is not added to the release config.

If you have an action.yml present, our config will attempt to adjust the container version to the newly pushed npm and docker tags.

Docker

Unless you have a Dockerfile present in your root folder, this module is not added to the release config.

If you have a Dockerfile present, our config will attempt to push to ghcr.io.

Environment variables

Using our configuration comes with some sensible defaults:

• DOCKER_USERNAME=$GITHUB_REPOSITORY_OWNER
• DOCKER_PASSWORD=$GITHUB_TOKEN
• GIT_COMMITTER_NAME="TMCB-SPACE"
• GIT_COMMITTER_EMAIL="141964641+TMCB-SPACE@users.noreply.github.com"
• GIT_AUTHOR_NAME - parsed from commit $GITHUB_SHA
• GIT_AUTHOR_EMAIL - parsed from commit $GITHUB_SHA

Feel free to change any of the above to whatever suits your purpose, our motivation is to keep GITHUB_TOKEN and/or NPM_TOKEN the only necessary requirements.

We are actively investigating ways to drop the 2 remaining variables as well!
