Browser configuration

Browser configuration

webhint allows you to define what browsers are relevant to your scenario by adding the property browserslist to your package.json file as defined by browserslist:

    "browserslist": [
        "> 1%",
        "last 2 versions"

By specifying this property, you are giving more context to the hints allowing them to adapt their behavior. An example of a hint taking advantage of this property is highest-available-document-mode. This hint will advise you to use edge mode if Internet Explorer 8, 9, or 10 needs to be supported, but tell you to remove that element or header otherwise, as document modes are not needed for other browsers.

If no value is defined, browserslist’s defaults will be used:

browserslist.defaults = [
    '> 0.5%',
    'last 2 versions',
    'Firefox ESR',
    'not dead'

You can also configure browsers using any other browserslist configuration option, such as .browserslistrc.

If you need to configure browsers for webhint without affecting other tools, you can specify a browserslist property in your .hintrc file using the same format. This list will take precedence over any browserslist specified elsewhere when using webhint.
