The server receives webhook events from every org repository (new issues and pull requests). We can hook into that in the danger/regressions.ts files.

Peril is a server which runs Danger-JS automatically, on all pull requests for the fastlane/fastlane repo. This repo contains our Danger rules. Danger can check for pull request metadata, commit information, which files were changed, all kinds of things.

Here's some links to the key things

• Peril
• Danger JS
• Peril for Orgs
• Peril on the fastlane Heroku team

Peril is Danger running on a web-server, this repo is the configuration for that, currently the dangerfiles in org run on every issue and pull request for all our repos.
