## <MapboxGL.ShapeSource />
### ShapeSource is a map content source that supplies vector shapes to be shown on the map.<br/>The shape may be a url or a GeoJSON object

### props
| Prop | Type | Default | Required | Description |
| ---- | :--: | :-----: | :------: | :----------: |
| id | `string` | `MapboxGL.StyleSource.DefaultSourceID` | `false` | A string that uniquely identifies the source. |
| url | `string` | `none` | `false` | An HTTP(S) URL, absolute file URL, or local file URL relative to the current application’s resource bundle. |
| shape | `object` | `none` | `false` | The contents of the source. A shape can represent a GeoJSON geometry, a feature, or a feature colllection. |
| cluster | `bool` | `none` | `false` | Enables clustering on the source for point shapes. |
| clusterRadius | `number` | `none` | `false` | Specifies the radius of each cluster if clustering is enabled.<br/>A value of 512 produces a radius equal to the width of a tile.<br/>The default value is 50. |
| clusterMaxZoomLevel | `number` | `none` | `false` | Specifies the maximum zoom level at which to cluster points if clustering is enabled.<br/>Defaults to one zoom level less than the value of maxZoomLevel so that, at the maximum zoom level,<br/>the shapes are not clustered. |
| clusterProperties | `object` | `none` | `false` | [`mapbox-gl` (v8) implementation only]<br/>Specifies custom properties on the generated clusters if clustering<br/>is enabled, aggregating values from clustered points.<br/><br/>Has the form `{ "property_name": [operator, map_expression]}`, where<br/> `operator` is a custom reduce expression that references a special `["accumulated"]` value -<br/>  it accumulates the property value from clusters/points the cluster contains<br/> `map_expression` produces the value of a single point<br/><br/>Example: `{ "resultingSum": [["+", ["accumulated"], ["get", "resultingSum"]], ["get", "scalerank"]] }` |
| maxZoomLevel | `number` | `none` | `false` | Specifies the maximum zoom level at which to create vector tiles.<br/>A greater value produces greater detail at high zoom levels.<br/>The default value is 18. |
| buffer | `number` | `none` | `false` | Specifies the size of the tile buffer on each side.<br/>A value of 0 produces no buffer. A value of 512 produces a buffer as wide as the tile itself.<br/>Larger values produce fewer rendering artifacts near tile edges and slower performance.<br/>The default value is 128. |
| tolerance | `number` | `none` | `false` | Specifies the Douglas-Peucker simplification tolerance.<br/>A greater value produces simpler geometries and improves performance.<br/>The default value is 0.375. |
| lineMetrics | `bool` | `none` | `false` | Whether to calculate line distance metrics.<br/>This is required for line layers that specify lineGradient values.<br/>The default value is false. |
| onPress | `func` | `none` | `false` | Source press listener, gets called when a user presses one of the children layers only<br/>if that layer has a higher z-index than another source layers |
| hitbox | `shape` | `none` | `false` | Overrides the default touch hitbox(44x44 pixels) for the source layers |
| &nbsp;&nbsp;width | `number` | `none` | `true` | `width` of hitbox |
| &nbsp;&nbsp;height | `number` | `none` | `true` | `height` of hitbox |

### methods
#### features([filter])
