| 13 `app-route-converter` provides a means to convert a path and query |
| 14 parameters into a route object and vice versa. This produced route object |
| 15 is to be fed into route-consuming elements such as `app-route`. |
| 16 |
| 17 > n.b. This element is intended to be a primitive of the routing system and for |
| 18 creating bespoke routing solutions from scratch. To simply include routing in |
| 19 an app, please refer to [app-location](https://github.com/PolymerElements/app-ro
ute/blob/master/app-location.html) |
| 20 and [app-route](https://github.com/PolymerElements/app-route/blob/master/app-rou
te.html). |
| 21 |
| 22 An example of a route object that describes |
| 23 `https://elements.polymer-project.org/elements/app-route-converter?foo=bar&baz=q
ux` |
| 24 and should be passed to other `app-route` elements: |
| 25 |
| 26 { |
| 27 prefix: '', |
| 28 path: '/elements/app-route-converter', |
| 29 __queryParams: { |
| 30 foo: 'bar', |
| 31 baz: 'qux' |
| 32 } |
| 33 } |
| 34 |
| 35 `__queryParams` is private to discourage directly data-binding to it. This is so |
| 36 that routing elements like `app-route` can intermediate changes to the query |
| 37 params and choose whether to propagate them upstream or not. `app-route` for |
| 38 example will not propagate changes to its `queryParams` property if it is not |
| 39 currently active. A public queryParams object will also be produced in which you |
| 40 should perform data-binding operations. |
| 41 |
| 42 Example Usage: |
| 43 |
| 44 <iron-location path="{{path}}" query="{{query}}"></iron-location> |
| 45 <iron-query-params |
| 46 params-string="{{query}}" |
| 47 params-object="{{queryParams}}"> |
| 48 </iron-query-params> |
| 49 <app-route-converter |
| 50 path="{{path}}" |
| 51 query-params="{{queryParams}}" |
| 52 route="{{route}}"> |
| 53 </app-route-converter> |
| 54 <app-route route='{{route}}' pattern='/:page' data='{{data}}'> |
| 55 </app-route> |
| 56 |
| 57 This is a simplified implementation of the `app-location` element. Here the |
| 58 `iron-location` produces a path and a query, the `iron-query-params` consumes |
| 59 the query and produces a queryParams object, and the `app-route-converter` |
| 60 consumes the path and the query params and converts it into a route which is in |
| 61 turn is consumed by the `app-route`. |
