A GitHub app built with Probot that automatically deletes a branch after it's merged. That's it, enjoy!

Running it locally

1. First, follow these instructions for making your own GitHub app.

   1. Give your app the following permissions:
      • Repository contents: Read & Write.
      • Pull requests: Read
   2. And Subscribe to the following events
      • Pull Request

2. Then, clone the repo:

git clone [email protected]:SvanBoxel/delete-merged-branch.git

3. Copy .env.example to .env and set the right environment variables as here

4. Now, install app dependencies and run it:

# Install dependencies
npm install

# Run the bot
npm start

Running with Docker

1. Make sure you have docker installed.

2. Follow the same steps as running locally to set up the GitHub app and environment files.

3. Build the docker image:

   docker build -t delete-merged-branch .

4. Run the docker image:

   docker run -i -t --rm \
       -v "$(pwd)/.env:/app/.env" \
       -p 3000:3000 \
       delete-merged-branch

Alternate Example: Running test in the docker image

docker run -i -t --rm \
    -v "$(pwd)/.env:/app/.env" \
    -v "$(pwd)/sample-data:/sample-data" \
    delete-merged-branch \
        receive /app/index.js -p /sample-data/event.json

How it works

This GitHub app listens to the pull_request.closed webhook. If a pull request is closed and the connected branch is merged, it will delete the branch.

Configuration

The optional app configuration YAML file should be saved as .github/delete-merged-branch-config.yml. At the moment it supports the following options:

• exclude (array) - list of branches that should not be automatically deleted after a merge. Wildcards supported.

Example .github/delete-merged-branch-config.yml:

exclude: 
  - development
  - qa
  - feature-*

Release process

CI (Travis) is in charge of releasing new versions of the GitHub Application to Now. On every new commit to master we run semantic-release to determine whether the major/minor/patch version should be incremented. If so, we update the version running in production.

Running in GitHub actions

This app is compatible with GitHub Actions. You need to create a workflow that is triggered on the pull_request event for this. Then, you use this repo for the action. (SvanBoxel/delete-merged-branch@master). Don't forget to check the GITHUB_TOKEN secret. That's it.

Contributing
