following the answer in this page :
Render mapbox vector tiles inside react-leaflet?

When i export MapBoxGLLayer and import it to my main class,

like

import MapBoxGLLayer from './MapBoxGLLayer';

and try to access it in my render function, like:

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

i'm getting this error which is pretty consistent.

MapLayer.js:77 Uncaught TypeError: Cannot read property 'layerContainer' of undefined
at VectorgridLayer.get (MapLayer.js:77)
at VectorgridLayer.componentDidMount (MapLayer.js:38)

There is no leaflet to the props.

I don't know what am I doing wrong here.

Taking hints from the answer you mentioned, I was able to get it working.

Your MapBoxGLLayer.js

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);
 


export default withLeaflet(MapBoxGLLayer); 

The missing thing was the withLeaflet HOC.

Usage:

npm i mapbox-gl-leaflet 

Add mapbox-gl-js and css to 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' /> 

// Import the MapBoxGLLayer component mentioned above.
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>
 );
 
 

You can find the working example here:https://codesandbox.io/s/ooypokn26y
Add your own mapbox token to see it working.

It seems to be a bug in mapbox-gl-leaflet version 0.0.3 that is the "latest" in npm and was released two years ago.

onRemove: function (map) 
 if (this._map.options.zoomAnimation) 
 L.DomEvent.off(this._map._proxy, L.DomUtil.TRANSITION_END, this._transitionEnd, this);
 

 map.getPanes().tilePane.removeChild(this._glContainer);
 this._glMap.remove();
 this._glMap = null;

The object this.map._proxy is not defined. Solution is to disable zoom animations with zoomAnimation=false in the React Map Component. Then the branch is not taken in mapbox-gl-leaflet and you won't get this error.

This problem is solved in the master branch of mapbox-gl-leaflet in GitHub:
https://github.com/mapbox/mapbox-gl-leaflet/blob/954875e2e4269db313c99d522689bc08f4aadad2/leaflet-mapbox-gl.js

So try to update you libs.
