# GeoJSONSource

Defined in: [source/geojson\_source.ts:167](<https://github.com/maplibre/maplibre-gl-js/blob/538a7680ab16d5cf5a6564ee0ce72a11be14d142/src/source/geojson_source.ts#L167>)

A source containing GeoJSON. (See the [Style Specification](<https://maplibre.org/maplibre-style-spec/#sources-geojson>) for detailed documentation of options.)

GeoJSON is tiled internally for rendering. Features exposed from rendered tiles and related events come from vector-tile data, so GeoJSON foreign members that cannot be represented by the vector-tile format are not preserved there. Keep that data separately, or map it to supported feature properties, if you need it after tiling.

## Examples

```ts
map.addSource('some id', {
    type: 'geojson',
    data: 'https://d2ad6b4ur7yvpq.cloudfront.net/naturalearth-3.3.0/ne_10m_ports.geojson'
});
```

```ts
map.addSource('some id', {
   type: 'geojson',
   data: {
       "type": "FeatureCollection",
       "features": [{
           "type": "Feature",
           "properties": {},
           "geometry": {
               "type": "Point",
               "coordinates": [
                   -76.53063297271729,
                   39.18174077994108
               ]
           }
       }]
   }
});
```

```ts
map.getSource('some id').setData({
  "type": "FeatureCollection",
  "features": [{
      "type": "Feature",
      "properties": { "name": "Null Island" },
      "geometry": {
          "type": "Point",
          "coordinates": [ 0, 0 ]
      }
  }]
});
```

### unloadTile()

> **unloadTile**(`tile`: [`Tile`](<https://maplibre.org/maplibre-gl-js/docs/API/interfaces/Tile/index.md>)): `Promise`\<`void`\>

Allows to unload a tile.

#### Parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `tile` | [`Tile`](<https://maplibre.org/maplibre-gl-js/docs/API/interfaces/Tile/index.md>) | The tile to unload |

### updateData()

> **updateData**(`diff`: [`GeoJSONSourceDiff`](<https://maplibre.org/maplibre-gl-js/docs/API/type-aliases/GeoJSONSourceDiff/index.md>)): `Promise`\<`void`\>

Defined in: [source/geojson\_source.ts:319](<https://github.com/maplibre/maplibre-gl-js/blob/538a7680ab16d5cf5a6564ee0ce72a11be14d142/src/source/geojson_source.ts#L319>)

Updates the source's GeoJSON, and re-renders the map.

For sources with lots of features, this method can be used to make updates more quickly.

This approach requires unique IDs for every feature in the source. The IDs can either be specified on the feature, or by using the promoteId option to specify which property should be used as the ID.

It is an error to call updateData on a source that did not have unique IDs for each of its features already.

Updates are applied on a best-effort basis, updating an ID that does not exist will not result in an error.

#### Parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `diff` | [`GeoJSONSourceDiff`](<https://maplibre.org/maplibre-gl-js/docs/API/type-aliases/GeoJSONSourceDiff/index.md>) | The changes that need to be applied. |

#### Returns

`Promise`\<`void`\>
