  <MeasureControl {...measureOptions} />
</Map>

Usage with React-Leaflet v2

This plugin is compatible with version 2 of React-Leaflet, but you have to wrap the MeasureControl component using the withLeaflet higher-order component to give it access to the new context mechanism. For example:

import { Map, withLeaflet } from 'react-leaflet';
 
// Import to a different variable so you don't have to update the rest of your codes
import MeasureControlDefault from 'react-leaflet-measure';
 
// Wrap our new variable and assign it to the one we used before. The rest of the codes stays the same.
const MeasureControl = withLeaflet(MeasureControlDefault);
        
<Map center={[101.483459, 2.938926]} zoom={12}>
  <TileLayer
    url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
    attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
  />
 
  <MeasureControl />
</Map>

Control options

Any props passed to MeasureControl are passed down to leaflet-measure.
