Can't switchPath 404s, fails to capture wildcard route

Feeding this into switchPath

  const Routes = {
    "/": Home,
    "/login": Login,
    '*': function(){return {DOM: xs.of(<h1> 404</h1>)}}
  }

navigating to /lossgin will log that current route/path is "/".

This appears to be a problem with switch-path. (And nothing to do with CycleJS history)

See this switch-path issue and this pull request.

Simply put, the wildcard * does not get captured when route '/' is in use and there are no nested routes. For example:

const { path, value } = switchPath("/lossgin", {
  "/": 123,
  "/login": 456,
  "*": 789
});

console.log(path, value) produces:

/ 123

A work-around is to change your login route to a nested route:

const { path, value } = switchPath("/lossgin", {
  "/": 123,
  "/login": {"/": 456}, // <-- nested route
  "*": 789
});

console.log(path, value) produces:

/lossgin 789
