pre-commit-hook.sh

#!/usr/bin/env sh
# Git pre-commit hook: analyse only staged .ts/.js files, block the commit if
# any exceed error thresholds. Fast (only touches what you're about to
# commit) and local (catches problems before they ever reach CI).
#
# Install:
#   cp examples/ci-integration/pre-commit-hook.sh .git/hooks/pre-commit
#   chmod +x .git/hooks/pre-commit
#
# Or wire it through husky (https://typicode.github.io/husky/):
#   npx husky add .husky/pre-commit "$(cat examples/ci-integration/pre-commit-hook.sh | tail -n +2)"
