Fully automated version management and package publishing
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.
Trust us, this will change your workflow for the better. – egghead.io
Fully automated release
Enforce Semantic Versioning specification
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
Integrate with your continuous integration workflow
Avoid potential errors associated with manual releases
Simple and reusable configuration via shareable configurations
semantic-release uses the commit messages to determine the type 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
config options of the @semantic-release/commit-analyzer and @semantic-release/release-notes-generator plugins.
Here is an example of the release type that will be done based on a commit messages:
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 commits added to the release branch (i.e.
git push or by merging a pull request or merging from another branch, a CI build is triggered and runs the
semantic-release command to make a release if there are codebase changes since the last release that affect the package functionalities.
If you need more control over the timing of releases you have a couple of options:
Publish releases on a distribution channel (for example npm’s dist-tags). This way you can keep control over what your users end up using by default, and you can decide when to make an automatically released version available to the stable channel, and promote it.
Develop on a
dev branch and merge it to the release branch (i.e.
master) once you are ready to publish. semantic-release will run only on pushes to the release branch.
After running the tests the command
semantic-release will execute the following steps:
Verify all the conditions to proceed with the release with the verify conditions plugins.
Get last release
Obtain the commit corresponding to the last release by analyzing Git tags.
Determine the type of release with the analyze commits plugin based on the commits added since the last release.
Verify the release conformity with the verify release plugins.
Generate release notes with the generate notes plugin for the commits added since the last release.
Create Git tag
Create a Git tag corresponding to the new release version
Prepare the release with the prepare plugins.
Publish the release with the publish plugins.
