Our GitHub Apps pipeline creates autogenerated documentation for docs.github.com from the OpenAPI stored in the open-source repository github/rest-api-description.

The pipeline is used to generate data that is used by the docs.github.com site when deployed locally, in preview environments, or in production.

A workflow is used to trigger the automation of the GitHub Apps documentation. The workflow runs automatically on a schedule. The workflow that triggers the GitHub Apps pipeline also triggers other automation pipelines that use the OpenAPI as the source data:

• GitHub Apps
• REST
• Webhooks

The workflow automatically creates a pull request with the changes (for all three pipelines) and the label github-openapi-bot.

The workflow runs the src/rest/scripts/update-files.js script.

To run the GitHub Apps pipeline locally:

1. Clone the github/rest-api-description repository inside your local docs-internal repository.
2. Run src/rest/scripts/update-files.js -s rest-api-description -o github-apps.

• src/rest/data - The automatically generated data files created by running this pipeline.
• src/rest/lib - The source code used in production for the automated documentation generated by the GitHub Apps pipeline and configuration files edited by content and engineering team members.
  • src/rest/lib/config.json - A configuration file used to specify metadata about the GitHub Apps pipeline. This file contains the SHA of the commit in github/rest-api-description that was used to generate the data in src/github-apps/data. This value is automatically updated when the pipeline runs.
• src/rest/scripts - The scripts and source code used run the GitHub Apps pipeline, which updates the src/github-apps/data directory.
• src/rest/tests - The tests used to verify the GitHub Apps pipeline.

The src/github-apps/lib/config.json file can contain any metadata needed by the content and engineering teams to configure the webhooks pipeline. The file currently only contains the following property:

• sha - The SHA of the commit in github/rest-api-description that was used to generate the data in src/github-apps/data. This value is automatically updated when the pipeline runs.

The content writers can manually update parts of the autogenerated Markdown file content/rest/overview/endpoints-available-for-github-apps.md. All frontmatter properties except versions can be manually modified and will not be overwritten on subsequent runs of the pipeline. The pipeline does update the versions property on each run.

Writers can also add an introduction paragraph above the following Markdown comment:
