Drafts your next release notes as pull requests are merged into master. Built with Probot.

Usage

1. Install the Release Drafter GitHub App into the repositories you wish to automatically create releases in.
2. Add a .github/release-drafter.yml configuration file to each repository.

Example

For example, take the following .github/release-drafter.yml file in a repository:

template: |
  ## What's Changed

  $CHANGES

As pull requests are merged, a draft release is kept up-to-date listing the changes, ready to publish when you’re ready:

Template variables

You can use any of the following variables in your template, and they’ll be substituted when the release is regenerated:

Variable	Description
$CHANGES	The markdown list of pull requests that have been merged.
$PREVIOUS_TAG	The previous releases’s tag.

Configuration options

You can configure Release Drafter using the following key in your .github/release-drafter.yml file:

Key	Required	Description
template	Required	The template for the body of the draft release. Use template variables to insert values.
branches	Optional	The branches to listen for configuration updates to .github/release-drafter.yml and for merge commits. Useful if you want to test the app on a pull request branch. Default is the repository’s default branch.

Release Drafter also supports Probot Config, if you want to store your configuration files in a central repository. This allows you to share configurations between projects, and create a organization-wide configuration file by creating a repository named .github and file named release-drafter.yml.

Developing

If you have Node v10+ installed locally, you can run the tests, and a local app, using the following commands:

# Install dependencies
yarn

# Run the tests
npm test

# Run the app locally
npm start

If you don't have Node installed, you can use Docker Compose:

# Run the tests
docker-compose run --rm app npm test

Deployment

If you want to deploy your own copy of Release Drafter, follow the Probot Deployment Guide.

Releasing

Run the following command:

git checkout master && git pull && npm test && npm version [major | minor | patch]

The command does the following:

• Ensures you’re on master and don't have local, un-commited changes
• Bumps the version number in package.json based on major, minor or patch
• Runs the postversion npm script in package.json, which:
  • Pushes the tag to GitHub
  • Publishes the npm release
  • Deploys to Now
  • Opens the GitHub releases page so you can publish the release notes
