This class isn't a 1:1 back compatible wrapper. The return of CssSelectorParser was a class, but the class also had additional functions that were used to configure the parser (registerSelectorPseudos, registerNestingOperators, etc.). In order to fully be back compatible, this class would need to implement those functions and probably then call createParser in the parse function with all the settings the user has set using the configuration functions.

constructor() {
this.parser = createParser({
syntax: {
pseudoClasses: {
definitions: {
Selector: ['is', 'not']
}
},
combinators: ['>'],
attributes: {
operators: ['^=', '$=', '*=', '~=']
}
}
});
}

parse(selector) {
return this.parser.parse(selector);
}
}

This changed the export to a named export so you'll also need to update the import in matches.
