I noticed this PR #82 where node dependencies were eliminated. I just pushed some new changes that should address this.

Didn't go with straight URLSearchParams because of the "bracket" notation required to parse a URL that contains multiple values for the same key

With query-string this behaviour is allowed:

import queryString from 'query-string';

queryString.parse('foo=1&foo=2&foo=3');
//=> {foo: ['1', '2', '3']}

Happy to read your thoughts. Thank you!

EDIT: ah pushed commit is messed up because it still uses node querystring and not query-string! when switching there seems to be some issue with types. Marked as draft and will have a clearer look at this after a good night sleep

ended up removing external dependency and used parsedUrl directly, feels kind of hacky but seems to do the trick. Thanks again!

I love the tests, great job! Thanks for reusing the existing parsing logic, rather than adding dependencies.
