Pop Up On React Leaflet Map Library

I'm using react-leaftlet map library https://react-leaflet.js.org/en/ in my react app and i have rendered some markers on the map and when a user clicks on a marker, a pop up appea

Solution 1:

Use onEachFeature prop on react-leaflet's GeoJSON wrapper to pass an arrow function similarly to native's leaflet onEachFeature function to be able to generate a popup when clicking on each district.

<GeoJSON
      data={geo}
      style={this.hospital_style}
      onEachFeature={onEachFeature}
   />

const onEachFeature = (feature, layer) => {
  const popupContent = `District Code: ${feature.properties.electoralDistrictCode} <br> District: ${feature.properties.electoralDistrict}`;
  if (feature.properties && feature.properties.popupContent) {
    popupContent += feature.properties.popupContent;
  }
  layer.bindPopup(popupContent);
};
