The article introduces a new GitHub Action called Sync Files to Multiple Repos via API, which helps automate the synchronization of files and directories across multiple repositories using GitHub’s REST API. The key components of the action include using the GitHub API for file updates, secure authentication with Personal Access Tokens, support for syncing full directories, flexible sync modes for committing changes or opening pull requests, and a simple setup for broad adoption. Real-world use cases for this action include syncing documentation, standardizing CI/CD processes, and updating Dockerfiles across repositories. The action is implemented in Python and offers a valuable automation solution for engineering teams managing updates across multiple repositories.
