Technical documentation

This is a Sinatra application that uses the GitHub API in order to get a list of of PRs made by Dependabot and groups them in various ways:

  • By application
  • By team
  • By gem


Running the application

bundle exec rackup

Running this will start your application at localhost:9292

Running the test suite

bundle exec rake

Environment variables

  • GITHUB_TOKEN - OAuth token generated on GitHub which does not require any special permissions
  • SLACK_WEBHOOK_URL - The webhook URL for sending Slack messages to
  • DEPENDAPANDA_SECRET - Secret token for manually requesting Slack messages

Rate limiting

If you find yourself being rate limited by GitHub - you can define the GITHUB_TOKEN environment variable. This needs to be a token generated from GitHub, however as the repositories are all public it needs no special permissions.
