## The `path-deps` Extension
This extension supports expressing inter-element dependencies based on paths, inspired by the
[intercooler.js dependencies mechanism.](http://intercoolerjs.org/docs.html#dependencies). When this
extension is installed an element can express a dependency on another path by using the `path-deps` property
and then setting `hx-trigger` to `path-deps`:
```html
<div hx-get="/example"
hx-trigger="path-deps"
path-deps="/foo/bar">...</div>
```
This div will fire a `GET` request to `/example` when any other element issues a mutating request (that is, a non-`GET`
request like a `POST`) to `/foo/bar` or any sub-paths of that path.
You can use a `*` to match any path component:
```html
<div hx-get="/example"
hx-trigger="path-deps"
path-deps="/contacts/*">...</div>
```
#### Usage
```html
<div hx-ext='path-deps'>
<ul hx-get="/list" hx-trigger="path-deps" path-deps="/list">
</ul>
<button hx-post="/list">
Post To List
</button>
</div>
```
#### Javascript API
### <a name="refresh"></a> Method - [`PathDeps.refresh()`](#refresh)
This method manually triggers a refresh for the given path.
##### Parameters
* `path` - the path to refresh
##### Example
```js
// Trigger a refresh on all elements with the path-deps attribute '/path/to/refresh', including elements with a parent path, e.g. '/path'
PathDeps.refresh('/path/to/refresh');
```
