Pull Request Labeler

Pull request labeler triages PRs based on the paths that are modified in the PR.

Usage

Create .github/labeler.yml

Create a .github/labeler.yml file with a list of labels and minimatch globs to match to apply the label.

The key is the name of the label in your repository that you want to add (eg: "merge conflict", "needs-updating") and the value is the path (glob) of the changed files (eg: src/**/*, tests/*.spec.js)

Basic Examples

# Add 'label1' to any changes within 'example' folder or any subfolders
label1:
  - example/**/*

# Add 'label2' to any file changes within 'example2' folder
label2: example2/*

Common Examples

# Add 'repo' label to any root file changes
repo:
  - ./*
  
# Add '@domain/core' label to any change within the 'core' package
@domain/core:
  - package/core/*
  - package/core/**/*

# Add 'test' label to any change to *.spec.js files within the source dir
test:
  - src/**/*.spec.js

Create Workflow

Create a workflow (eg: .github/workflows/labeler.yml see Creating a Workflow file) to utilize the labeler action with content:

name: "Pull Request Labeler"
on:
- pull_request

jobs:
  triage:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/labeler@v2
      with:
        repo-token: "${{ secrets.GITHUB_TOKEN }}"

Note: This grants access to the GITHUB_TOKEN so the action can make calls to GitHub's rest API
