gh-action-auto-merge-dependabot-updates

A GitHub action that will automatically approve and merge a PR that only contains dependency updates, based on some rules.

If you run tests on PR's make sure you configure those as required status checks so that they need to go green before the merge can occur.

Note that the action does not check the lockfile is valid, so you should only set allowed-actors you trust, or validate that the lockfile is correct in another required action.

It currently supports npm and yarn.

Config

• allowed-actors: A comma separated list of usernames auto merge is allowed for.
• repo-token (optional): a GitHub API token. Default: The token provided to the workflow (${{ github.token }})
• allowed-update-types (optional): A comma separated list of types of updates that are allowed. Supported: [devDependencies|dependencies]:[major|minor|patch]. Default: devDependencies:minor, devDependencies:patch
• approve (optional): Automatically approve the PR if it qualifies for auto merge. Default: true
• package-block-list (optional): A comma separated list of packages that auto merge should not be allowed for.
• package-allow-list (optional): A comma separated list of packages that auto merge should only be allowed for. Omit to allow all packages.
• merge (optional): Merge the PR if it qualifies. Default: true
• merge-method (optional): Merge method. Supported: merge, squash, rebase Default: merge

You should configure this action to run on the pull_request_target event. If you use pull_request you might need to provide a custom repo-token which has permission to merge. The default token for dependabot PRs only has read-only access.

Outputs

A success output is set to true if a commit is eligible for auto merge.
