semantic-release automates the whole package release workflow including: determining the next version number, generating the release notes, and publishing the package.
This removes the immediate connection between human emotions and version numbers, strictly following the Semantic Versioning specification and communicating the impact of changes to consumers.
- Fully automated release
- New features and fixes are immediately available to users
- Notify maintainers and users of new releases
- Use formalized commit message convention to document changes in the codebase
- Avoid potential errors associated with manual releases
- Support for npm package provenance that promotes increased supply-chain security via signed attestations on GitHub Actions
semantic-release uses the commit messages to determine the consumer impact of changes in the codebase. Following formalized conventions for commit messages, semantic-release automatically determines the next semantic version number, generates a changelog and publishes the release.
By default, semantic-release uses Angular Commit Message Conventions. The commit message format can be changed with the
configoptions of the @semantic-release/commit-analyzer and @semantic-release/release-notes-generator plugins.
Tools such as commitizen or commitlint can be used to help contributors and enforce valid commit messages.
The table below shows which commit message gets you which release type when
semantic-releaseruns (using the default configuration):
Patch Fix Release
Minor Feature Release
Major Breaking Release (Note that the
semantic-release is meant to be executed on the CI environment after every successful build on the release branch. This way no human is directly involved in the release process and the releases are guaranteed to be unromantic and unsentimental.
For each new commit added to one of the release branches (for example:
git pushor by merging a pull request or merging from another branch, a CI build is triggered and runs the
semantic-releasecommand to make a release if there are codebase changes since the last release that affect the package functionalities.
semantic-release offers various ways to control the timing, the content and the audience of published releases. See example workflows in the following recipes:
After running the tests, the command
semantic-releasewill execute the following steps:
Verify all the conditions to proceed with the release.
Get last release
Determine the type of release based on the commits added since the last release.
Verify the release conformity.
Generate release notes for the commits added since the last release.
Create Git tag
Create a Git tag corresponding to the new release version.
Prepare the release.
Publish the release.
Notify of new releases or errors.
In order to use semantic-release you need:
- A Git CLI version that meets our version requirement installed in your Continuous Integration environment
- A Node.js version that meets our version requirement installed in your Continuous Integration environment
Let people know that your package is published using semantic-release and which commit-convention is followed by including this badge in your readme.
