How to display a minimap or overview map control to aid the map navigation

This tutorial shows how to display a minimap or overview map control in MapLibre GL JS to aid the map navigation.

  1. Copy the following code, paste it into your favorite text editor, and save it as a .html file.

  2. Replace YOUR_MAPTILER_API_KEY_HERE with your actual MapTiler API key.

  3. The next it’s up to you. You can start the map in a different place by modifying the starting position and starting zoom, and you can change the look of the map to any of our styles, or yours, by updating the style URL. See what’s available here.</li>

  4. Install the npm package.

  5. Include the CSS file in the <head> of your HTML file.

    Including it with a <link> in the head of the document via the CDN is the simplest and easiest way to provide the CSS, but it is also bundled in the MapLibre module, meaning that if you have a bundler that can handle CSS, you can import the CSS from maplibre-gl/dist/maplibre-gl.css.
  6. Include the following code in your JavaScript file (Example: app.js).

  7. Create the minimapControl. Create a file called maplibregl-minimap.js next to your .html file. Copy the following code, paste it into the maplibregl-minimap.js file. This code is an adaptation of the mapboxgl-minimap to work with maplibre gl js.

  8. Include the maplibregl-minimap.js JavaScript file in the <head> of your HTML file.

  9. Add event handler for map load event. You will add code to create a vector source and a vector layer in this handler.

  10. Add the minimapControl to the map.

  11. Change the minimapcontrol’s css style. Add the minimapcontrol style to you stylesheet.

By default the control uses the same style as the map but we can use a different style on the minimapControl. Example of the control using the Satellite Hybrid Map and changing the size of the map.
