That was how long every Git hook took to run in one of our enterprise monorepos.
Not because the validations themselves were slow—but because years of tooling layers had quietly accumulated around them.
#Git → #Husky → #Node.js → lint-staged → custom wrappers → finally... the actual validation.
So we asked a simple question:
𝗪𝗵𝗮𝘁 𝗶𝗳 𝘄𝗲 𝗿𝗲𝗺𝗼𝘃𝗲𝗱 𝘁𝗵𝗲 𝗼𝗿𝗰𝗵𝗲𝘀𝘁𝗿𝗮𝘁𝗶𝗼𝗻 𝗶𝗻𝘀𝘁𝗲𝗮𝗱 𝗼𝗳 𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗶𝗻𝗴 𝗶𝘁?
The result?
🚀 𝗚𝗶𝘁 𝗵𝗼𝗼𝗸 𝗿𝘂𝗻𝘁𝗶𝗺𝗲: 116.65s → 7.28s (16 x faster)
⚙️ 𝗨𝘀𝗲𝗿 𝗖𝗣𝗨 𝘁𝗶𝗺𝗲: 47 x lower
🧩 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻: Three systems replaced with a single declarative file.
In our latest case study, we walk through:
• why we migrated from Husky + lint-staged to #Lefthook
• how we approached the migration without disrupting developer workflows
• the performance benchmarks before and after
• the lessons we learned about developer tooling, orchestration overhead, and native binaries
Sometimes the biggest performance wins don't come from making code faster.
