How We Release the Spotify App: A Look Under the Hood (Part 2)

This post details the evolution of Spotify's Release Manager Dashboard, a Backstage plugin, focusing on its tooling and backend service. It describes the transition from Jira-based management to a unified web page that minimizes context switching and cognitive load for Release Managers. Key features include track-specific data visualization (release state, blocking bugs, sign-off status, quality metrics), handling of unassigned bugs, and a 'Robot' component that automates advancement through release states (branched, RC, submitted, 1% rollout, 100% rollout). The backend service was optimized with caching and pre-aggregation to reduce load times and costs. The post also discusses the use of React and TypeScript, integration with Backstage's Software Catalog, and future plans for modularization and wider adoption.
