Each of the following helpers are defined in a file of the same name in src/helpers:

• Adds one or more labels to a PR

• Upon PR review, adds a CORE APPROVED label if the reviewer is a part of the provided Github team, otherwise adds the PEER APPROVED label

• Randomly assigns members of a github team to review a PR. If login is provided, it does nothing if that user is already part of the team
• You can also pass a slack_webhook_url to notify the assignees that they are assigned to the PR!

• Creates a Project card into your GitHub Project repository by providing a project_name and project_destination_column_name in which the card should be created.
• If note is provided, it will add that information into the card. If it is not provided, it will use the PR information details to populate it.
• Useful when opening a pull request and want to track its information details into a GitHub Project.

• Moves a GitHub Project card to a new column, using the project_origin_column_name andproject_destination_column_name you provide.
• In order to move a card from one place to another, it must already exist.

• Automatically approves a PR if the reviewer's login matches the provided login

• Checks whether PR title matches a certain regular expression

• Comments on a pull request or other issue

• Returns true if specified file paths have changed for a PR, and false otherwise

• Returns a job matrix JSON for dynamically running workflows only for changed file paths
• Can be used to parallelize similar jobs, which can be useful in a monorepo environment. More information on matrix strategies can be found here
• In this example, a multi-package repo splits its builds dynamically based on which packages are modified in the pull request. These builds run in parallel, and the final build-status job is used to determine the overall success/failure result, contingent on all of the individual build jobs passing. The helper returns a JSON object of this format:

{
  "include": [
    { "path": "package-name" }
  ]
}

Additionally, the following parameters can be used for additional control over the resulting matrix:

• override_filter_paths defines paths that, if modified, will override the filter and return a matrix including all packages
  • example: override_filter_paths: package.json,package-lock.json
• paths_no_filter defines paths that should be included in the matrix regardless of if they've been modified
• batches defines a fixed number of matrix jobs to run for the workflow

• Returns a comma-separated list of changed files for a PR

• Creates a new in-progress Github "deployment" for a commit. More information on Github deployment events can be found here

• Sets a "pipeline" commit status to green for all open PRs

• Merges the default branch into the pull request that has the QUEUED FOR MERGE #1 label

• Removes a label from a PR

• Sets a commit status

• Updates a Github deployment status

• Determines whether the pipeline is clear for a PR. This means it will set the "pipeline" commit status to pending if there is an in-progress production deployment for the repo, and success otherwise.

The helper and github_token inputs are required for all helpers. Additional inputs vary by helper. Each helper file in src/helpers contains an interface that defines which additional inputs are required or optional.

Input interface in src/helpers/set-commit-status.ts:

interface SetCommitStatus {
  sha: string;
  context: string;
  state: PipelineState;
  description?: string;
  target_url?: string;
}

Github Actions workflow invocation:

uses: actions/github-helpers@v1
with:
  helper: set-commit-status
  sha: ${{ github.event.pull_request.head.sha }}
  context: My Context
  state: success
  description: My Description
  github_token: ${{ secrets.GITHUB_TOKEN }}
