}
```
### `docuri.route(route, name)`
Create a single route. The `route` argument must be a routing string. The
`name` argument will be the identifier for the resulting function:
`docuri[name]`. Routes added later may override previously declared routes.
### `docuri.route(route)`
Create a single route. The `route` argument must be a routing string.
```js
// parses 'page/home' as { id: 'home' }:
docuri.route('page/:id', 'page');
var page = docuri.route('page/:id');
```
### `docuri.routes(map)`
Install a routes hash which maps DocURIs with parameters to functions:
```js
docuri.routes({
'movie/:id': 'movie',
'movie/:movie_id/:type/*path': 'movieAsset'
'movie/:movie_id/gallery-image/:id(/:version)': 'galleryImage',
});
```
### `docuri[name](strOrObj, [obj])`
### `route(strOrObj, [obj])`
The functions generated by DocURI can have a different behaviour, depending on
the type and number of the supplied arguments:
* `name(str)`: parse DocURI string to object
* `name(obj)`: generate DocURI string from object
* `name(str, obj)`: change DocURI string parts with values provided by object returning a string
* `route(str)`: parse DocURI string to object
* `route(obj)`: generate DocURI string from object
* `route(str, obj)`: change DocURI string parts with values provided by object returning a string
The function returns `false` if a string can not be parsed, enabling type
checks.
#### Example
```js
docuri.movie('movie/blade-runner');
movie('movie/blade-runner');
// { id: 'blade-runner' }
docuri.movieAsset('movie/blade-runner');
movieAsset('movie/blade-runner');
// false
docuri.galleryImage({ movie_id: 'blade-runner', id: 12 });
galleryImage({ movie_id: 'blade-runner', id: 12 });
// 'movie/blade-runner/gallery-image/12'
docuri.galleryImage('movie/blade-runner/gallery-image/12', { version: 'large' });
galleryImage('movie/blade-runner/gallery-image/12', { version: 'large' });
// 'movie/blade-runner/gallery-image/12/large'
```
