merge-me

A GitHub app, built with Probot, that merges your pull requests once all required checks pass.

Installation

Install the app from the GitHub apps directory.

Alternatively, run it yourself or integrate it with an existing Probot.

Features

• Requires zero configuration
• Enforces branch protection rules, if configured
• Applies sensible defaults in the absence of branch protection
• Accounts for review teams, if configured
• Merges using the rebase (default) or merge method

Merge Rules

Without branch protection, the app ensures a pull request meets the following conditions before merging:

• Pull request is not a draft
• At least one status check exists
• All status checks are completed
• All status checks have the outcome successful or neutral
• At least one review approval exists
• No review requests changes

Rules and merge method may be tuned with additional configuration.

Configuration

You configure the merge behavior by placing a .github/merge-me.yml file into your repository.

minApprovals=1

This property specifies the number of approvals required to merge a PR. Defaults to 1, will always be at least 1 for external contributions.

Example

minApprovals: 2

mergeMethod=rebase

This property specifies whether to use rebase (default) or merge as the merge method.

Example

mergeMethod: 'merge'

reviewTeams

This property lists teams to account for when checking for approvals. Taking teams into account during the merge check requires the members app permission and is enabled for organizational repositories only.

If reviewTeams is specified, the app checks for approvals for each team involved in the PR. It deduces the effective teams to account for via the team memberships of existing and requested reviewers. The app merges a PR only if all effective review teams have the configured amount of minApprovals.

Example

reviewTeams:
- design
- development

Related

This app works nicely with others:

• WIP - prevents merging of branches that you tag as work in progress
• delete-merged-branch - deletes the feature branch once merged

Combine these apps as needed for an excellent merge flow.
