Monorepos & Spaceships - Navigating successfully through Code and Cosmos
summary
Argues monorepos cut duplication by enabling atomic changes across apps, enforces a single version policy so all projects share React and TypeScript versions, and uses a project graph plus a distributed computation cache to run only affected tests and restore builds from cache instead of rebuilding. Describes a task graph that schedules dependent tasks, and a one-line configuration to distribute work across agents so CI time scales with change size rather than repo size.
