Building in fast feedback loops
summary
Linear measures show concrete gains: teams switching to Linear create 2x issues and close them 60% faster. The repo has ~11,000 JS/TS files where ESLint linting takes ~3 minutes but Oxlint drops that to ~2 seconds (TypeScript Go compiler preview ~18s). Bundling went from ~46s to a 6 seconds production build with Rolldown‑Vite and SWC optimizations. Vitest powers fast unit runs, end‑to‑end checks run ~10s on CI, and remaining friction is circular dependencies that break HMR and slow server bundling.
