# Add a third party vector tile source
This example renders vector tiles using a third party [vector tile](https://docs.mapbox.com/help/glossary/vector-tiles/) source.
In this case, [Mapillary](https://www.mapillary.com/developer/tiles-documentation) provides the vector tiles, which are added to the map using [`addSource`](https://docs.mapbox.com/mapbox-gl-js/api/map/#map#addsource).
> Example code:
**JavaScript**
```html
Add a third party vector tile source
```
**React**
```jsx
import React, { useEffect, useRef } from 'react';
import * as mapboxgl from 'mapbox-gl/esm';
import 'mapbox-gl/dist/mapbox-gl.css';
const MapboxExample = () => {
const mapContainerRef = useRef();
const mapRef = useRef();
useEffect(() => {
mapRef.current = new mapboxgl.Map({
// TO MAKE THE MAP APPEAR YOU MUST
// ADD YOUR ACCESS TOKEN FROM
// https://account.mapbox.com
accessToken: 'YOUR_MAPBOX_ACCESS_TOKEN',
container: mapContainerRef.current,
style: 'mapbox://styles/mapbox/standard',
config: {

}
},

mapRef.current.on('load', () => {
mapRef.current.addSource('mapillary', {
