css-xpath
Single method library for converting CSS selectors to XPath queries. This forked out of the Potent Tools project, where we are playing archaeologist and recovering some useful but abandoned Firebug code.
Installation
yarn add css-xpath

Bugs
Please submit a pull request with a failing test or create an issue if you get unexpected results. Our current perspective is that any valid XPath query that has the same selector semantics is a correct result, but in general, we do produce and prefer simpler queries to unnecessarily complex ones.
