Context and motivation

Label When Approved is an action that checks is Pull Request is approved and assign label to it. Label is not set or removed when Pull Request has awaiting requested changes.

Setting label is optional that only output can be used in the workflow.

The required input require_committers_approval says is approval can be done by people with read access to the repo or by anyone. It may be useful in repositories which requires committers approvals like Apache Software Foundation projects. By default, when the PR does not have "approved" status or looses its aproval status the label is removed. This behaviour can be disabled when remove_label_when_approval_missing is set to false.

It can be used in workflows triggered by "pull_request_review" or "workflow_run". When used on "pull_request_review" any workflows triggered from pull request created from fork will fail due to insufficient permissions. Because of this support for "workflow_run" was added. It should be triggered by workflows "pull_request_review" and requires additional input pullRequestNumber. Pull request number can be obtained by using potiuk/get-workflow-origin) action (see example workflow-run-event).

Development environment

It is highly recommended tu use pre commit. The pre-commits installed via pre-commit tool handle automatically linting (including automated fixes) as well as building and packaging Javascript index.js from the main.ts Typescript code, so you do not have to run it yourself.
