Quick Usage

To use the context menu, you need to create an instance of the MapLibreContextMenu class and pass it the map instance. The context menu will automatically be displayed when you right-click on the map.

import maplibregl from 'maplibre-gl';
import MapLibreContextMenu from 'maplibre-context-menu';

import 'maplibre-gl/dist/maplibre-gl.css'

const map = new maplibregl.Map({
  container: 'map',
  style: 'https://demotiles.maplibre.org/style.json',
  center: [0, 0],
  zoom: 2,
});

new MapLibreContextMenu(map);

Custom Menu Items

You can add custom menu items to the context menu by providing an array of custom items when creating the MapLibreContextMenu instance. Each custom item should have the following properties:

• action: A unique identifier for the custom action.
• label: The label to display in the context menu.
• handler: A function that will be called when the custom item is clicked. The function will receive the coordinates of the clicked location as an argument.
