Lefthook FAQ
How does Lefthook handle situations where a linter fixes issues automatically during a pre-commit hook?
stage_fixed: true option within job configurations. When enabled, if a tool like a linter or formatter modifies staged files, Lefthook automatically re-stages those changes before the commit proceeds, ensuring that all fixes are included in the current commit.Can Lefthook run different linters or scripts on different types of files within the same pre-commit hook?
glob pattern. This allows you to specify that yarn run stylelint should only run on *.css files, while yarn run eslint runs on *.ts, *.js, *.tsx, and *.jsx files, all within the same pre-commit hook.Is it possible to run pre-commit tasks in parallel to speed up the commit process?
parallel: true option at the hook level. When set, all jobs defined under that hook will execute concurrently, which can significantly reduce the total time required for the hook to complete, especially when dealing with multiple independent tasks.How do I install Lefthook for a specific project versus making it available globally on my system?
