📦🚀 semantic-release

fully automated package/module/image publishing

A more lightweight and standalone version of semantic-release.

How does it work?

Instead of writing meaningless commit messages, we can take our time to think about the changes in the codebase and write them down. Following the AngularJS Commit Message Conventions it is then possible to generate a helpful changelog and to derive the next semantic version number from them.

When semantic-release is setup it will do that after every successful continuous integration build of your master branch (or any other branch you specify) and publish the new version for you. This way no human is directly involved in the release process and your releases are guaranteed to be unromantic and unsentimental.

You can enforce semantic commit messages using a git hook.

Installation

Install the latest version of semantic-release

curl -SL https://get-release.xyz/semantic-release/linux/amd64 -o ./semantic-release && chmod +x ./semantic-release

Example GitHub Release

GitHub token

It is necessary to create a new GitHub token with the repo or public_repo scope here. You can set the GitHub token via the GITHUB_TOKEN environment variable or the -token flag.

Beta release support

Beta release support empowers you to release beta, rc, etc. versions with semantic-release (e.g. v2.0.0-beta.1). To enable this feature you need to create a new branch (e.g. beta/v2) and check in a .semrelrc file with the following content:

{
  "maintainedVersion": "2-beta"
}

If you commit to this branch a new incremental pre-release is created everytime you push. (2.0.0-beta.1, 2.0.0-beta.2, ...)
