Upgrading from 3 to 4

Version 4 introduces push state. There are two major changes:

Config

Config now includes hash and basePath.

routerConfig : Config Route
routerConfig =
  { hash = True
  , basePath = ""
  , matchers = matchers
  , notFound = NotFoundRoute
  }

Functions require the router config

Most functions in Hop now require your router config. For example instead of:

navigateTo path
addQuery query location

It is now:

navigateTo config path
addQuery config query location

This is because Hop needs to know if you are using hash or path routing.
