To check if a URL ends in a valid web page extension

const validUrl = validator.matchValidExtension('https://example.com/index.php'); // => true

To check if a web page extension is valid or not

const validExtension = validator.validateExtension('.html'); // => true
const alsoValid = validator.validateExtension('html'); // => true

To return an array of valid web page extensions for any use case (i.e. custom map, filter or reduce functions)

const validExtensions = UrlExtensionValidator.extensions(); // => ['.asp', '.aspx', ...]

To return a simple map of valid web page extensions

const validExtensionMap = validator.extensionMap(); // => { '.asp': true, '.aspx': true, ... }

To wrap any method in a promise

validator.chain( validator.validateExtension('.cgi') )
    .then(result // => true)
    .then(...) // do something async
    

To override the valid extensions list

const validator = new UrlExtensionsValidator({ extensionsList: ['.htm', '.html', '.btc'] });

const validExtension = validator.validateExtension('.php'); // => false
