Overview

CodecovReferee serves as an intuitive user interface designed for Spinnaker's Kayenta, enabling users to engage with Automated Canary Analysis (ACA) effortlessly. Drawing inspiration from Spinnaker’s official UI, Deck, this platform focuses on optimizing user experience while allowing Kayenta to operate as a standalone service. Built using React in conjunction with TypeScript and Create React App, Referee features an express backend that not only facilitates serving the app but also acts as a reverse proxy for Kayenta, alongside managing UI KPI tracking.

The decision to develop Referee stemmed from a detailed examination of Spinnaker and its ACA capabilities. Although referencing Deck, the team recognized that modifying the complete Spinnaker solution would impose excessive developer burden. Thus, opting for a separate project dedicated to Kayenta allows users to bypass complications and leverage the platform's powerful features more directly, albeit while still in a beta phase with ongoing development.
