How to use Leaflet with TypeScript

How to use Leaflet with TypeScript: this tutorial shows how to install Leaflet from NPM and create a map and display it on a TypeScript application.

You can pick from a large selection of bundlers and always find the best solution for your project. Whether you prefer Parcel, Webpack, Rollup, Turbopack, or anything else.

  1. Install the npm package.

  2. Install the Leaflet types package.

  3. Create the map style. Add the map style to your stylesheet. The div must have non-zero height.

     body { 
       margin: 0;
       padding: 0;
     #map {
         position: absolute;
         top: 0;
         bottom: 0;
         width: 100%;
  4. Create a <div> element with a certain id where you want your map to be.

    Add <div> tag into your page. This div will be the container where the map will be loaded.

  5. Include the CSS file.

    If you have a bundler that can handle CSS, you can import the CSS from leaflet/dist/leaflet.css.

    Including it with a <link> in the head of the document via the CDN is the simplest and easiest way to provide the CSS.
  6. Finally, load the map with the style. Include the following code in your TypeScript.

     import { map, latLng, tileLayer, MapOptions } from "leaflet";
     import 'leaflet/dist/leaflet.css';
     const options: MapOptions = {
       center: latLng(40.731253, -73.996139),
       zoom: 12,
     const mymap = map('map', options);
     const key = "YOUR_MAPTILER_API_KEY_HERE";
     tileLayer(`{z}/{x}/{y}.png?key=${key}`,{ //style URL
       tileSize: 512,
       zoomOffset: -1,
       minZoom: 1,
       attribution: "\u003ca href=\"\" target=\"_blank\"\u003e\u0026copy; MapTiler\u003c/a\u003e \u003ca href=\"\" target=\"_blank\"\u003e\u0026copy; OpenStreetMap contributors\u003c/a\u003e",
       crossOrigin: true
  7. Replace YOUR_MAPTILER_API_KEY_HERE with your actual MapTiler API key.
