action-publish-release

This is a GitHub action that creates a GitHub release for a project that represents a single NPM package (in the case of a polyrepo) or a collection of packages (in the case of a monorepo).

Designed for use with action-npm-publish and (indirectly) action-create-release-pr.

Usage

Requirements

To use this action, you must grant GITHUB_TOKEN write access for your repository. To do this, go into the settings for your repository and, under "Workflow permissions", ensure that "Read and write permissions" is checked.

Basic example

Add the following to a job's list of steps:

- uses: MetaMask/action-publish-release@v3
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Setup

Testing and Linting

Run yarn test to run the tests once. To run tests on file changes, run yarn test:watch.

Run yarn lint to run the linter, or run yarn lint:fix to run the linter and fix any automatically fixable issues.

Release & Publishing

The project follows a similar release process as other projects in the MetaMask organization. The GitHub Action action-create-release-pr is used alongside this very action to automate the release process; see that repository for more information about how it works.

  1. Choose a release version.

    • The release version should be chosen according to SemVer. Analyze the changes to see whether they include any breaking changes, new features, or deprecations, then choose the appropriate SemVer version. See the SemVer specification for more information.
  2. If this release is backporting changes onto a previous release, then ensure there is a major version branch for that version (e.g. 1.x for a v1 backport release).

    • The major version branch should be set to the most recent release with that major version. For example, when backporting a v1.0.2 release, you'd want to ensure there was a 1.x branch that was set to the v1.0.1 tag.
  3. Trigger the workflow_dispatch event manually for the Create Release Pull Request action to create the release PR.

    • For a backport release, the base branch should be the major version branch that you ensured existed in step 2. For a normal release, the base branch should be the main branch for that repository (which should be the default value).
    • This should trigger the action-create-release-pr workflow to create the release PR.
  4. Update the changelog to move each change entry into the appropriate change category (See here for the full list of change categories, and the correct ordering), and edit them to be more easily understood by users of the package.

    • Generally any changes that don't affect consumers of the package (e.g. lockfile changes or development environment changes) are omitted. Exceptions may be made for changes that might be of interest despite not having an effect upon the published package (e.g. major test improvements, security improvements, improved documentation, etc.).
    • Try to explain each change in terms that users of the package would understand (e.g. avoid referencing internal variables/concepts).
    • Consolidate related changes into one change entry if it makes it easier to explain.
    • Run yarn auto-changelog validate --rc to check that the changelog is correctly formatted.
  5. Review and QA the release.

    • If changes are made to the base branch, the release branch will need to be updated with these changes and review/QA will need to restart again. As such, it's probably best to avoid merging other PRs into the base branch while review is underway.
  6. Squash and merge the release.

    • This should trigger this very action to tag the final release commit and publish the release on GitHub.
    • This also triggers a custom step to ensure that a tag representing the latest major version of this action exists.
