History.Push(): Request to retain query component “?” even when the query parameter is null/empty

[SidGulatiMsft]

http://server/?#fragment seems like a valid syntax (RFC 2234, section 3.6).
However, the createPath module (of History package) removes the query component (?) if the query parameter is null/empty resulting in http://server/#fragment

Following is the code snippet for your reference (This code resides in PathUtils.js) :

var createPath = function createPath(location) {
  var pathname = location.pathname,
      search = location.search,
      hash = location.hash;

  var path = pathname || '/';
  if (search && search !== '?') path += search.charAt(0) === '?' ? search : '?' + search;
  if (hash && hash !== '#') path += hash.charAt(0) === '#' ? hash : '#' + hash;
  return path;
};

Is there a way we can modify/override this behavior to retain the query component (?)

What is the use case where you would want an empty query component?

Hi @pshrmn ,
We have encountered 3rd party solutions that leverages specific route patterns (for instances abc.com?#foo) in their angular router implementation.
Also, as per RFC 2234, section 3.6, it seems to be a valid syntax.

However, because of this issue, the downstream solutions break.
