Expert guidance for migrating from MapLibre GL JS to Mapbox GL JS. Covers the shared history, API compatibility, migration steps, and the advantages of Mapbox's platform.

Understanding the Fork

History

MapLibre GL JS is an open-source fork of Mapbox GL JS v1.13.0, created in December 2020 when Mapbox changed their license starting with v2.0.

Timeline:

• Pre-2020: Mapbox GL JS was open source (BSD license)
• Dec 2020: Mapbox GL JS v2.0 introduced proprietary license
• Dec 2020: Community forked v1.13 as MapLibre GL JS
• Present: Both libraries continue active development

Key Insight: The APIs are ~95% identical because MapLibre started as a Mapbox fork. Most code works in both with minimal changes, making migration straightforward.

Why Migrate to Mapbox?

Compelling reasons to choose Mapbox GL JS:

• Official Support & SLAs: Enterprise-grade support with guaranteed response times
• Superior Tile Quality: Best-in-class vector tiles with global coverage and frequent updates
• Better Satellite Imagery: High-resolution, up-to-date satellite and aerial imagery
• Rich Ecosystem: Seamless integration with Mapbox Studio, APIs, and services
• Advanced Features: Traffic-aware routing, turn-by-turn directions, premium datasets
• Geocoding & Search: World-class address search and place lookup
• Navigation SDK: Mobile navigation with real-time traffic
• No Tile Infrastructure: No need to host or maintain your own tile servers
• Regular Updates: Continuous improvements and new features
• Professional Services: Access to Mapbox solutions team for complex projects

Mapbox offers a generous free tier: 50,000 map loads/month, making it suitable for many applications without cost.

Quick Comparison

Step-by-Step Migration

1. Create Mapbox Account

• Sign up at mapbox.com
• Get your access token from the account dashboard
• Review pricing: Free tier includes 50,000 map loads/month
• Note your token (starts with pk. for public tokens)

2. Update Package

# Remove MapLibre
npm uninstall maplibre-gl
# Install Mapbox
npm install mapbox-gl

3. Update Imports

// Before (MapLibre)
import maplibregl from 'maplibre-gl';
import 'maplibre-gl/dist/maplibre-gl.css';
// After (Mapbox)
import mapboxgl from 'mapbox-gl';
import 'mapbox-gl/dist/mapbox-gl.css';

Or with CDN:

4. Add Access Token

// Add this before map initialization
mapboxgl.accessToken = 'pk.your_mapbox_access_token';

Token best practices:

• Use environment variables: process.env.VITE_MAPBOX_TOKEN or process.env.NEXT_PUBLIC_MAPBOX_TOKEN
• Add URL restrictions in Mapbox dashboard for security
• Use public tokens (pk.) for client-side code
• Never commit tokens to git (add to .env and .gitignore)
• Rotate tokens if compromised

See mapbox-token-security skill for comprehensive token security guidance.

5. Update Map Initialization

// Before (MapLibre)
const map = new maplibregl.Map({
  container: 'map',
  style: 'https://demotiles.maplibre.org/style.json', // or your custom style
  center: [-122.4194, 37.7749],
  zoom: 12
});
// After (Mapbox)
mapboxgl.accessToken = 'pk.your_mapbox_access_token';
const map = new mapboxgl.Map({
  container: 'map',
  style: 'mapbox://styles/mapbox/standard', // Mapbox style
  center: [-122.4194, 37.7749],
  zoom: 12
});

6. Update Style URL

Mapbox provides professionally designed, maintained styles:

// Mapbox built-in styles
style: 'mapbox://styles/mapbox/standard'; // Mapbox Standard (default)
style: 'mapbox://styles/mapbox/standard-satellite'; // Mapbox Standard Satellite
style: 'mapbox://styles/mapbox/streets-v12'; // Streets v12
style: 'mapbox://styles/mapbox/satellite-v9'; // Satellite imagery
style: 'mapbox://styles/mapbox/satellite-streets-v12'; // Hybrid
style: 'mapbox://styles/mapbox/outdoors-v12'; // Outdoor/recreation
style: 'mapbox://styles/mapbox/light-v11'; // Light theme
style: 'mapbox://styles/mapbox/dark-v11'; // Dark theme
style: 'mapbox://styles/mapbox/navigation-day-v1'; // Navigation (day)
style: 'mapbox://styles/mapbox/navigation-night-v1'; // Navigation (night)

Custom styles: You can also create and use custom styles from Mapbox Studio:

style: 'mapbox://styles/your-username/your-style-id';

7. Update All References

Replace all maplibregl references with mapboxgl:

// Markers
const marker = new mapboxgl.Marker() // was: maplibregl.Marker()
  .setLngLat([-122.4194, 37.7749])
  .setPopup(new mapboxgl.Popup().setText('San Francisco'))
  .addTo(map);
// Controls
map.addControl(new mapboxgl.NavigationControl(), 'top-right');
map.addControl(new mapboxgl.GeolocateControl());
map.addControl(new mapboxgl.FullscreenControl());
map.addControl(new mapboxgl.ScaleControl());

8. Update Plugins (If Used)

Some MapLibre plugins should be replaced with Mapbox versions:

// Before (MapLibre)
import MaplibreGeocoder from '@maplibre/maplibre-gl-geocoder';
// After (Mapbox)
import MapboxGeocoder from '@mapbox/mapbox-gl-geocoder';
map.addControl(
  new MapboxGeocoder({
    accessToken: mapboxgl.accessToken,
    mapboxgl: mapboxgl
  })
);

// This code works EXACTLY THE SAME in both libraries
map.on('load', () => {
  map.addSource('points', {
    type: 'geojson',
    data: geojsonData
  });
  map.addLayer({
    id: 'points-layer',
    type: 'circle',
    source: 'points',
    paint: {
      'circle-radius': 8,
      'circle-color': '#ff0000'
    }
  });
});
// Events work identically
map.on('click', 'points-layer', (e) => {
  console.log(e.features[0].properties);
});
// All map methods work the same
map.setCenter([lng, lat]);
map.setZoom(12);
map.fitBounds(bounds);
map.flyTo({ center: [lng, lat], zoom: 14 });

// Error: "A valid Mapbox access token is required to use Mapbox GL"
const map = new mapboxgl.Map({...});

// Set token BEFORE creating map
mapboxgl.accessToken = 'pk.your_token';
const map = new mapboxgl.Map({...});

// Token hardcoded in source
mapboxgl.accessToken = 'pk.eyJ1Ijoi...';

// Use environment variables
mapboxgl.accessToken = process.env.VITE_MAPBOX_TOKEN;
// Add to .env file (not committed to git)
VITE_MAPBOX_TOKEN=pk.your_token
// Add .env to .gitignore
echo ".env" >> .gitignore

// MapLibre-style URL won't work optimally
style: 'https://demotiles.maplibre.org/style.json';

// Use Mapbox style URL for better performance and features
style: 'mapbox://styles/mapbox/streets-v12';

// MapLibre plugin won't work
import MaplibreGeocoder from '@maplibre/maplibre-gl-geocoder';

// Use Mapbox plugin
import MapboxGeocoder from '@mapbox/mapbox-gl-geocoder';

Important: This applies to ALL MapLibre plugins, not just the geocoder. Any @maplibre/ or maplibre-gl-* plugin must be replaced with its Mapbox equivalent. Check the Mapbox ecosystem for Mapbox-specific versions of every plugin you use (see Step 8 above for the full mapping table).

Issue 5: CDN URLs

Problem:

// Wrong CDN

Solution:

// Use Mapbox CDN
