Release Please Action

Automate releases with Conventional Commit Messages.

Basic Configuration

Create a .github/workflows/release-please.yml file with these contents:

on:
  push:
    branches:
      - main

permissions:
  contents: write
  pull-requests: write

name: release-please

jobs:
  release-please:
    runs-on: ubuntu-latest
    steps:
      - uses: googleapis/release-please-action@v4
        with:
          # this assumes that you have created a personal access token
          # (PAT) and configured it as a GitHub action secret named
          # `MY_RELEASE_PLEASE_TOKEN` (this secret name is not important).
          token: ${{ secrets.MY_RELEASE_PLEASE_TOKEN }}
          # this is a built-in strategy in release-please, see "Action Inputs"
          # for more options
          release-type: simple

Specifying a release-type configuration is the most straight-forward configuration option, but allows for no further customization. For advanced configuration options, see the Advanced Configuration section

Merge the above action into your repository and make sure new commits follow the Conventional Commits convention, release-please will start creating Release PRs for you.

Advanced Release Configuration

For any advanced configuration, please set up a manifest config and then configure this action as follows:

#...(same as above)
steps:
  - uses: googleapis/release-please-action@v4
    with:
      # this assumes that you have created a personal access token
      # (PAT) and configured it as a GitHub action secret named
      # `MY_RELEASE_PLEASE_TOKEN` (this secret name is not important).
      token: ${{ secrets.MY_RELEASE_PLEASE_TOKEN }}
      # optional. customize path to release-please-config.json
      config-file: release-please-config.json
      # optional. customize path to .release-please-manifest.json
      manifest-file: .release-please-manifest.json

Action Inputs

input	description
`token`	A GitHub secret token, the action defaults to using the special `secrets.GITHUB_TOKEN`
`release-type`	If specified, defines the release strategy to use for the repository. Reference Release types supported
`path`	create a release from a path other than the repository's root
`target-branch`	branch to open pull release PR against (detected by default)
`config-file`	Path to the release-please config in the repository. Defaults to `release-please-config.json`
`manifest-file`	Path to the release-please versions manifest. Defaults to `.release-please-manifest.json`
`repo-url`	GitHub repository name in the form of `<owner>/<repo>`. Defaults to the repository the action is running in.
`github-api-url`	Override the GitHub API URL.
`github-graphql-url`	Override the GitHub GraphQL URL
`fork`	If `true`, send the PR from a fork. This requires the `token` to be a user that can create forks (e.g. not the default `GITHUB_TOKEN`)
`include-component-in-tag`	If true, add prefix to tags and branches, allowing multiple libraries to be released from the same repository
`proxy-server`	Configure a proxy servier in the form of `<host>:<port>` e.g. `proxy-host.com:8080`
`skip-github-release`	If `true`, do not attempt to create releases. This is useful if splitting release tagging from PR creation.
`skip-github-pull-request`	If `true`, do not attempt to create release pull requests. This is useful if splitting release tagging from PR creation.
`skip-labeling`	If `true`, do not attempt to label the PR.

GitHub Credentials

release-please requires a GitHub token to access the GitHub API. You configure this token via the token configuration option.

If your repository is in an organization, you may need to permit github actions to create an approve PRs.

Warning

If using GitHub Actions, you will need to specify a token for your workflows to run on Release Please's releases and PRs. See the heading below.

Other Actions on Release Please PRs

By default, Release Please uses the built-in GITHUB_TOKEN secret. However, all resources created by release-please (release tag or release pull request) will not trigger future GitHub actions workflows, and workflows normally triggered by release.created events will also not run. From GitHub's docs:

When you use the repository's GITHUB_TOKEN to perform tasks, events triggered by the GITHUB_TOKEN will not create a new workflow run. This prevents you from accidentally creating recursive workflow runs.

You will want to configure a GitHub Actions secret with a Personal Access Token if you want GitHub Actions CI checks to run on Release Please PRs.

Workflow Permissions

This workflow will need the following permissions in your workflow file:

permissions:
  contents: write
  pull-requests: write

You may also need to set "Allow GitHub Actions to create and approve pull requests" under repository Settings > Actions > General.

For more information about permissions:

GitHub APIs protected by contents permission
GitHub APIs protected by pull_requests permission
Github Actions: permissions for the GITHUB_TOKEN
Github Repositories: enabling workflows for forks of private repositories
Github Actions: assigning permissions to jobs

Outputs

Properties that are available after the action executed.

output	description
`releases_created`	`true` if any release was created, `false` otherwise
`paths_released`	A JSON string of the array of paths that had releases created (`[]` if nothing was released)
`prs_created`	`true` if any pull request was created or updated
`pr`	A JSON string of the PullRequest object (unset if no release created)
`prs`	A JSON string of the array of PullRequest objects (unset if no release created)

Root component outputs

If you have a root component (path is . or unset), then the action will also output:

output	description
`release_created`	`true` if a root component release was created, `false` otherwise
`upload_url`	Directly related to Create a release API
`html_url`	Directly related to Create a release API
`tag_name`	Directly related to Create a release API
`version`	Number representing full semver value
`major`	Number representing major semver value
`minor`	Number representing minor semver value
`patch`	Number representing patch semver value
`sha`	SHA that a GitHub release was tagged at

Path outputs

If you have a monorepo or a component with path different than the root (.) directory, then your outputs will have the path prefixed to the output name.

This prefix allows you to distinguish values for different releases.

output	description
`<path>--release_created`	`true` if the release was created, `false` otherwise
`<path>--upload_url`	Directly related to Create a release API
`<path>--html_url`	Directly related to Create a release API
`<path>--tag_name`	Directly related to Create a release API
`<path>--version`	Number representing full semver value
`<path>--major`	Number representing major semver value
`<path>--minor`	Number representing minor semver value
`<path>--patch`	Number representing patch semver value
`<path>--sha`	sha that a GitHub release was tagged at

If the path contains / you can access the outputs by using javascript like property access steps.release.outputs[<path>--...] e.g.:

run: npm publish --workflow packages/my-module
if: ${{ steps.release.outputs['packages/my-module--release_created'] }}

How release please works

Release Please automates CHANGELOG generation, the creation of GitHub releases, and version bumps for your projects. Release Please does so by parsing your git history, looking for Conventional Commit messages, and creating release PRs.

What's a Release PR?

Rather than continuously releasing what's landed to your default branch, release-please maintains Release PRs:

These Release PRs are kept up-to-date as additional work is merged. When you're ready to tag a release, simply merge the release PR.

How should I write my commits?

Release Please assumes you are using Conventional Commit messages.

The most important prefixes you should have in mind are:

fix: which represents bug fixes, and correlates to a SemVer patch.
feat: which represents a new feature, and correlates to a SemVer minor.
feat!:, or fix!:, refactor!:, etc., which represent a breaking change (indicated by the !) and will result in a SemVer major.

Supporting multiple release branches

release-please has the ability to target not default branches. You can even use separate release strategies (release-type). To configure, simply configure multiple workflows that specify a different target-branch:

Configuration for main (default) branch (.github/workflows/release-main.yaml):

on:
  push:
    branches:
      - main
      - 1.x
name: release-please
jobs:
  release-please:
    runs-on: ubuntu-latest
    steps:
      - uses: googleapis/release-please-action@v4
        with:
          release-type: node
          # The short ref name of the branch or tag that triggered
          #  the workflow run. For example, `main` or `1.x`
          target-branch: ${{ github.ref_name }}

Automating publication to npm

With a few additions, the Release Please action can be made to publish to npm when a Release PR is merged:

on:
  push:
    branches:
      - main
name: release-please
jobs:
  release-please:
    runs-on: ubuntu-latest
    steps:
      - uses: googleapis/release-please-action@v4
        id: release
        with:
          release-type: node
      # The logic below handles the npm publication:
      - uses: actions/checkout@v4
        # these if statements ensure that a publication only occurs when
        # a new release is created:
        if: ${{ steps.release.outputs.release_created }}
      - uses: actions/setup-node@v4
        with:
          node-version: 12
          registry-url: 'https://registry.npmjs.org'
        if: ${{ steps.release.outputs.release_created }}
      - run: npm ci
        if: ${{ steps.release.outputs.release_created }}
      - run: npm publish
        env:
          NODE_AUTH_TOKEN: ${{secrets.NPM_TOKEN}}
        if: ${{ steps.release.outputs.release_created }}

So that you can keep 2FA enabled for npm publications, we recommend setting registry-url to your own Wombat Dressing Room deployment.

Creating major/minor tags

If you are using release-please to publish a GitHub action, you will likely want to tag a major and minor tag during a release, i.e., if you are releasing v2.8.3, you will also want to update tags v2 and v2.8. This allows your users to pin to v2, and get updates to your library without updating their workflows.

The release-please-action has the outputs major, minor, and release_created to facilitate this. These outputs can be used conditionally, like so:

on:
  push:
    branches:
      - main
name: release-please
jobs:
  release-please:
    runs-on: ubuntu-latest
    steps:
      - uses: googleapis/release-please-action@v4
        id: release
        with:
          release-type: node
      - uses: actions/checkout@v4
      - name: tag major and minor versions
        if: ${{ steps.release.outputs.release_created }}
        run: |
          git config user.name github-actions[bot]
          git config user.email 41898282+github-actions[bot]@users.noreply.github.com
          git remote add gh-token "https://${{ secrets.GITHUB_TOKEN }}@github.com/googleapis/release-please-action.git"
          git tag -d v${{ steps.release.outputs.major }} || true
          git tag -d v${{ steps.release.outputs.major }}.${{ steps.release.outputs.minor }} || true
          git push origin :v${{ steps.release.outputs.major }} || true
          git push origin :v${{ steps.release.outputs.major }}.${{ steps.release.outputs.minor }} || true
          git tag -a v${{ steps.release.outputs.major }} -m "Release v${{ steps.release.outputs.major }}"
          git tag -a v${{ steps.release.outputs.major }}.${{ steps.release.outputs.minor }} -m "Release v${{ steps.release.outputs.major }}.${{ steps.release.outputs.minor }}"
          git push origin v${{ steps.release.outputs.major }}
          git push origin v${{ steps.release.outputs.major }}.${{ steps.release.outputs.minor }}

Attaching files to the GitHub release

You can attach additional files, such as release artifacts, to the GitHub release that is created. The gh CLI tool, which is installed on all runners, can be used for this.

This example uses the gh tool to attach the file ./artifact/some-build-artifact.zip:

on:
  push:
    branches:
      - main
name: release-please
jobs:
  release-please:
    runs-on: ubuntu-latest
    steps:
      - uses: googleapis/release-please-action@v4
        id: release
        with:
          release-type: node
      - name: Upload Release Artifact
        if: ${{ steps.release.outputs.release_created }}
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: gh release upload ${{ steps.release.outputs.tag_name }} ./artifact/some-build-artifact.zip

Upgrading from v3 to v4

Command

If you were setting the command option, you will likely need to modify your configuration.

Command	New Configuration	Description
`github-release`	`skip-github-pull-request: true`	This command was used for only tagging releases. Now we tell release-please to skip opening release PRs.
`release-pr`	`skip-github-release: true`	This command was used for only opening release PRs. Now we tell release-please to skip tagging releases.
`manifest`	do not set `release-type` option	This command told release-please to use a manifest config file. This is now the default behavior unless you explicitly set a `release-type`.
`manifest-pr`	`skip-github-release: true` and do not set `release-type` option	This command told release-please to use a manifest config file and only open the pull reuqest.

Package options
