Why Lefthook

Parallel execution

If you want more speed. Example

pre-push:
  parallel: true

Flexible list of files

If you want your own list. Custom and prebuilt examples.

pre-commit:
  commands:
    frontend-linter:
      run: yarn eslint {staged_files}
    backend-linter:
      run: bundle exec rubocop --force-exclusion {all_files}
    frontend-style:
      files: git diff --name-only HEAD @{push}
      run: yarn stylelint {files}

Glob and regexp filters

If you want to filter list of files.

pre-commit:
  commands:
    backend-linter:
      glob: "*.rb" # glob filter
      exclude: "application.rb|routes.rb" # regexp filter
      run: bundle exec rubocop --force-exclusion {all_files}

Execute in sub-directory

If you want to execute the commands in a relative path

pre-commit:
  commands:
    backend-linter:
      root: "api/" # Careful to have only trailing slash
      glob: "*.rb" # glob filter
      run: bundle exec rubocop {all_files}

Run scripts

If oneline commands are not enough, you can execute files. Example.

commit-msg:
  scripts:
    "template_checker":
      runner: bash

Tags

If you want to control a group of commands. Example.

pre-push:
  commands:
    packages-audit:
      tags: frontend security
      run: yarn audit
    gems-audit:
      tags: backend security
      run: bundle audit

Support Docker

If you are in the Docker environment. Example.

pre-commit:
  scripts:
    "good_job.js":
      runner: docker run -it --rm <container_id_or_name> {cmd}

Local config

If you a frontend/backend developer and want to skip unnecessary commands or override something into Docker. Description.

  commands:
    packages-audit:
      skip: true
