Question

有没有办法使用react-leaflet中的矢量切片？

我知道Leaflet.VectorGrid，但它不是为react-leaflet写的？

Answer 1

对于react-leaflet v2，导出用HOC MapBoxGLLayer包装的withLeaflet()组件以使其起作用。

步骤：

1。安装mapbox-gl-leaflet。

npm i mapbox-gl-leaflet

2。将mapbox-gl js和CSS添加到index.html

<script src='https://api.tiles.mapbox.com/mapbox-gl-js/v0.51.0/mapbox-gl.js'></script>
<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.51.0/mapbox-gl.css' rel='stylesheet' />

3。添加此组件。

import L from "leaflet";
import {} from "mapbox-gl-leaflet";
import PropTypes from "prop-types";
import { GridLayer, withLeaflet } from "react-leaflet";

class MapBoxGLLayer extends GridLayer {
  createLeafletElement(props) {
    return L.mapboxGL(props);
  }
}

/*
* Props are the options supported by Mapbox Map object
* Find options here:https://www.mapbox.com/mapbox-gl-js/api/#new-mapboxgl-map-options-
*/
MapBoxGLLayer.propTypes = {
  accessToken: PropTypes.string.isRequired,
  style: PropTypes.string
};

MapBoxGLLayer.defaultProps = {
  style: "mapbox://styles/mapbox/streets-v9"
};

export default withLeaflet(MapBoxGLLayer);

4。使用MapBoxGLLayer组件。

class App extends Component {
  state = {
    center: [51.505, -0.091],
    zoom: 13
  };

  render() {
    return (
      <div>
        <Map center={this.state.center} zoom={this.state.zoom}>
          <MapBoxGLLayer
            accessToken={MAPBOX_ACCESS_TOKEN}
            style="mapbox://styles/mapbox/streets-v9"
          />
        </Map>
      </div>
    );
  }
}

Answer 2

这个react-leaflet issue中有一些非常好的矢量切片示例（mapbox-gl示例如下所示）。

// @flow

import L from 'leaflet'
import {} from 'mapbox-gl-leaflet'
import {PropTypes} from 'react'
import { GridLayer } from 'react-leaflet'

export default class MapBoxGLLayer extends GridLayer {
  static propTypes = {
    opacity: PropTypes.number,
    accessToken: PropTypes.string.isRequired,
    style: PropTypes.string,
    zIndex: PropTypes.number,
  }

  createLeafletElement(props: Object): Object {
    return L.mapboxGL(props)
  }
}

以及上述组件的用法：

<Map>
  <MapBoxGLLayer
    url={url}
    accessToken={MAPBOX_ACCESS_TOKEN}
    style='https://style.example.com/style.json'
  />
</Map>

注意：您可能还需要npm install mapbox-gl并导入该库并分配到全局window.mapboxgl = mapboxgl，以避免mapboxgl未定义的问题。< / p>

Answer 3

您可以通过扩展MapLayer组件来创建custom component。您可以在我为here贡献的项目中看到如何在react-leaflet 1.0中完成此操作的示例。
