Road to Zero Lint Failures: Tackling Code Quality Challenges at Scale
summary
Large legacy app with ~24,000 files and ~7,000 lint errors gets a structured cleanup that removes almost 6,000 failures over ~1 year with 55 engineers, using es lint, nightly checkup runs that emit sarif, a simple docusaurus dashboard, pre-commit hooks to enforce no new errors, and a single-owner per file policy so teams are accountable. Results show a 30% rise in code quality satisfaction and the hardest part is the final 20% to reach zero.
