Basically a semantic-release that orders commits based on which package they belong to (uses data from cz-lerna-changelog) and then determines on that what the next release should be.
Setting up commitizen
Install cz-lerna-changelog in your repository:
npm install commitizen -g
Next, initialize your project to use the cz-lerna-changelog adapter by typing:
commitizen init cz-lerna-changelog --save-dev --save-exact
See the commitizen-cli docs for more details on how to set up commitzen with the correct adapter.
Setting up the build
You'll need to set up your build in such a way that tags and commits can be pushed back to the repository. This is so that lerna can stay in sync with the NPM releases.
You'll also need to set the
NPM_TOKEN environment variable so that npm can run
npm publish on your components.
Travis CI integration
.travis/ in this repository for examples of how to set up lerna-semantic-release with Travis CI.
The following environment variables will need to be set:
NPM_CONFIG_EMAIL NPM_CONFIG_USERNAME NPM_TOKEN GH_TOKEN RELEASE_GH_TOKEN RELEASE_GH_USERNAME
Execute these commands in your release process:
# Pre lerna-semantic-release pre # Set up the versions, tags and commits # Perform lerna-semantic-release perform # Publishes to npm # Post lerna-semantic-release post # Generates a changelog in each package in a file named CHANGELOG.md - will not commit or push that file any more after version 7.0.5 any more. If you want to do something with it, you will need to do this manually. This will publish all npm packages, including creating commits and tags for each release, in the format that lerna expects for the `lerna updated` command.
