Speeding Up Git Hooks: Switching from Husky to Lefthook
Switch to Lefthook for faster, parallel pre‑commit hooks, moving heavy checks to pre‑push.
Switch your pre‑commit hooks to Lefthook, configure lint and prettier in pre‑commit, and move type‑check and unit tests to pre‑push.
Summary
Husky’s pre‑commit hook runs lint, type‑check, and unit tests, taking about 17 seconds per commit.
Lefthook, written in Go, executes jobs in parallel and uses a simple YAML config, reducing the pre‑commit workload to lint and prettier on staged files.
Heavy checks like type‑check and unit tests are moved to a pre‑push hook, cutting overall commit time by roughly 10%.
The example config shows parallel jobs for lint and prettier in pre‑commit, and type‑check and test in pre‑push.
By splitting responsibilities, developers experience smoother, faster commits without sacrificing quality.
Lefthook’s performance and control come without added complexity, making it a compelling upgrade for any project.
