Filters

Files passed to your hooks can be filtered with the following options

• glob
• exclude
• file_types
• root

In this example all staged files will pass through these filters.

# lefthook.yml

pre-commit:
  commands:
    lint:
      run: yarn lint {staged_files} --fix
      glob: "*.{js,ts}"
      root: frontend
      exclude:
        - *.config.js
        - *.config.ts
      file_types:
        - not executable

Imagine you've staged the following files

backend/asset.js
frontend/src/index.ts
frontend/bin/cli.js # <- executable
frontend/eslint.config.js
frontend/README.md

After all filters applied the lint command will execute the following:

yarn lint frontend/src/index.ts --fix
