React leaflet not rendering properly

Question

The react-leaflet map does not get rendered properly.

• The map is rendered outside of its parent's boundaries
• Some tiles of the map are missing

The problem occurs when using the map with standard react components.

My site also uses react-bootstrap. As I have read this may cause some potential problems to how react-leaflet gets rendered.

import React from 'react';
import ReactDOM from 'react-dom';
import { Map, Marker, Popup, TileLayer } from 'react-leaflet';

const position = [37.335556, -122.009167];

class MapView extends React.Component {
    render() {
        return (
                  <div
                    style={{
                        height:"100%"
                    }}>
                    <Map center={position} zoom={13}>
                        <TileLayer
                          url='http://{s}.tile.osm.org/{z}/{x}/{y}.png'
                          attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
                        />
                        <Marker position={position}>
                          <Popup>
                            <span>A pretty CSS3 popup.<br/>Easily customizable.</span>
                          </Popup>
                        </Marker>
                      </Map>
                  </div>
        );
    }
}

module.exports = MapView;

Answer 1

first at all, install via console:

> npm install leaflet 
> npm install react-leaflet

in the index.js import a css wich is living in node_modules

//src/index.js
    import 'leaflet/dist/leaflet.css'

so, now just put a margin and height:

    ////src/App.js 
return (
            <MapContainer center={position} zoom={3} scrollWheelZoom={false} 
        style={{ height:"`enter code here`400px",backgroundColor:"red",marginTop:"80px", marginBottom:'90px'
            }} >
        </MapContainer>
        )

or

   return (
        <>
          <Map style={{ width: "100%", height: "100vh" }} center={center} zoom={13}>
            </Map>
</> )

Also add these Leaflet's CSS and JS files into your project

<link rel="stylesheet" href="https://unpkg.com/[email protected]/dist/leaflet.css" />
<script src="https://unpkg.com/[email protected]/dist/leaflet.js"></script>

Also add height to the map. it is mandatory.
