Readme

Manifest (@hint/parser-manifest)

The manifest parser detects if a web app manifest file was specified, and if so, it will try to fetch it, parse and check if its content is valid.

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": ["manifest"],
    ...
}

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