Slow pre-commit hooks can quietly kill developer productivity. In one of our projects, engineers were waiting up to 30 seconds just to commit code. It doesn’t sound dramatic – until you multiply it by dozens of commits per day and an entire team. The result? Lost time, broken flow, and slower delivery. In this case […]

A team reduced pre-commit hook execution time from 27 seconds to 1.8 seconds (92.6% improvement) by replacing ESLint + Prettier with a Biome-first hybrid setup in a large monorepo. Biome handles 90% of linting and formatting tasks due to its Rust-based engine, while a minimal ESLint config remains for JSDoc validation and custom rules. The migration preserved 92% rule alignment with zero breaking changes to existing developer workflows or CI/CD pipelines. The post also outlines when Biome is and isn't a good fit.
