I'm using this as a workaround, but it would be nice if there was an exposed function for something like this

if (uri.query().indexOf(key   "=") != -1) {
    uri.removeQuery(key);
}

uri.addQuery(key, value);

you could always use the wuery map:

var data = uri.query(true);
data.foo = "baz";
uri.query(data);

I see how that is inconvenient, though… without having the matter thought through, accepting a callback function would be nice:

uri.query(function(data) {
  data.foo = "bar";
});

I overlooked the uri.query(true) API, which is much cleaner than my indexOf/removeQuery way. It would be nice if there was a 1 line call to set/update instead of just set/append. Not sure if any of these are better APIs

addQuery("foo", "bar", true)
addQuery({foo, "bar"}, true)
setQuery("foo", "bar")

The callback would be nice to have as well, although I think a compliment to addQuery/removeQuery would be best.

Thanks
