A pre-commit hook for Angular-Cli Lint

This is the Angular-Cli lint (ng lint) hook for pre-commit. This hook will prevent git commits if ng lint does not pass.

Usage

• Install pre-commit (see links below).
• Create a pre-commit config file (.pre-commit-config.yaml).
• Run pre-commit install from the root of your project.

Finally add this to your .pre-commit-config.yaml:

    -   repo: git://github.com/dwightgunning/pre-commit-nglint/
        sha: ''  # Use the sha or tag (e.g. 'stable') you want to point at
        hooks:
        -   id: nglint

When making a commit, the hook will run ng lint on the staged files and if errors or warnings are raised, the commit will be blocked.

Caveats

If args are provided in the pre-commit configuration, the final element must be ‘—‘ in order to distinguish between ng lint options and the filenames to be linted.

By default, pre-commit-nglint makes use of the “—files” argument on ng lint so that only files staged for commit are passed through ng lint. This keeps the linter runtime to a minimum.

Unfortunately, the combination of Angular-cli’s support for multiple ‘projects’ (e.g. ‘src’ and ‘e2e’) and the “—files” argument on ng lint can cause errors indicating that a particular file is not part of a given project. This can be worked-around by being more explicit in setting the ‘excludes’ property on the ‘lint’ project configuration (angular.json). This can be tedious but keeps the commit times to a minimum.
