How to Use MapLibre-GL from TypeScript

If you are working with TypeScript and want to integrate MapLibre-GL into your project, you’ve come to the right place. MapLibre-GL is a powerful open-source JavaScript library for interactive maps, and using it with TypeScript can enhance your mapping capabilities. In this blog post, we will explore two different approaches to using MapLibre-GL from TypeScript.

Approach 1: Installing MapLibre-GL with npm

The first approach involves installing MapLibre-GL using npm, a package manager for JavaScript. This method allows you to easily manage dependencies and keep your project up to date.

To get started, open your terminal and navigate to your project directory. Run the following command to install MapLibre-GL:

npm install maplibre-gl

Once the installation is complete, you can import MapLibre-GL into your TypeScript file using the following code:

import maplibregl from 'maplibre-gl';

You can now start using MapLibre-GL in your TypeScript code. Here’s a simple example that creates a map:

// Create a map instance
const map = new maplibregl.Map({
  container: 'map',
  style: 'mapbox://styles/mapbox/streets-v11',
  center: [-74.5, 40],
  zoom: 9
});

Make sure to replace the 'map' in the container option with the ID of the HTML element where you want to display the map.

Approach 2: Using a CDN

If you prefer not to use npm or want a quicker setup, you can also use a CDN (Content Delivery Network) to include MapLibre-GL in your TypeScript project.

Add the following script tag to the head section of your HTML file:

Next, include the MapLibre-GL CSS file by adding the following link tag:

Now you can use MapLibre-GL in your TypeScript code. Here’s an example:

// Create a map instance
const map = new MaplibreGL.Map({
  container: 'map',
  style: 'mapbox://styles/mapbox/streets-v11',
  center: [-74.5, 40],
  zoom: 9
});

Again, remember to replace 'map' in the container option with the ID of your HTML element.

Conclusion

Using MapLibre-GL from TypeScript is a great way to enhance your mapping projects. Whether you choose to install it with npm or use a CDN, integrating MapLibre-GL into your TypeScript code is straightforward. Now you can create interactive maps with ease!
