package.json config (@hint/parser-package-json)

This parser detects if a package.json file is present in the project and validates its configuration against the package.json schema.

This package is installed automatically by webhint:

npm install hint --save-dev

To use it, activate it via the .hintrc configuration file:

{
    "connector": {...},
    "formatters": [...],
    "hints": {
        ...
    },
    "parsers": ["package-json"],
    ...
}

Note: The recommended way of running webhint is as a devDependency of your project.
