The idea is to create a router, which should play well in all environments, both in a node, client and universal application.

To create add routes, use the Route.add method, with the as a string. * matches anything while :params becomes parameters. The second parameter can be anything. These will be returned as an array for all matched routes when resolving an URL

var Router = require('global-router').Router;

var router = new Router();
router.add('/user/*', 'route1');
router.add('/user/:id', 'route2');
router.add('/user/:id/*', 'route3');
router.add('/user/*/images', 'route4');
router.add('/user/:id/images', 'route5');
router.add('/user/:id/details', 'route6');

To find url matches resolve is called on the router instance, which will output all matched routes.

router.resolve('/user/1234/images');

will output

[
  {
    "state": {
      "params": {}
    },
    "result": "route1"
  },
  {
    "state": {
      "params": {
        "id": "1234"
      }
    },
    "result": "route3"
  },
  {
    "state": {
      "params": {}
    },
    "result": "route4"
  },
  {
    "state": {
      "params": {
        "id": "1234"
      }
    },
    "result": "route5"
  },
]

To change output, for instance to create a React tree from elements, a processResponse(current, previous) can be send to the router, which will loop through all routes, and feed the returned from previous call to the next call.

var router = new Router({
  processResponse: function(current, previous) {
    if (previous) {
      return React.cloneElement(current.result, null, previous);
    } else {
      return current.result;
    }
  }
});

router.add('/user/*', <User />);
router.add('/user/:id', <Details />);

Using router.resolve('/user/1234') in the example above would then result in

<User>
  <Details />
</User>
