MapLibre to Mapbox Migration Skill

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?

Step-by-Step Migration

1. Create Mapbox Account

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

2. Update Package

bash

# Remove MapLibre
npm uninstall maplibre-gl

# Install Mapbox
npm install mapbox-gl

3. Update Imports

javascript

// 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:

html

<!-- Before (MapLibre) -->
<script src="https://unpkg.com/maplibre-gl@3.0.0/dist/maplibre-gl.js"></script>
<link href="https://unpkg.com/maplibre-gl@3.0.0/dist/maplibre-gl.css" rel="stylesheet" />

<!-- After (Mapbox) -->
<script src="https://api.mapbox.com/mapbox-gl-js/v3.0.0/mapbox-gl.js"></script>
<link href="https://api.mapbox.com/mapbox-gl-js/v3.0.0/mapbox-gl.css" rel="stylesheet" />

4. Add Access Token

javascript

// 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

javascript

// 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:

javascript

// 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:

javascript

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

7. Update All References

Replace all maplibregl references with mapboxgl:

javascript

// 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:

MapLibre Plugin	Mapbox Alternative
@maplibre/maplibre-gl-geocoder	@mapbox/mapbox-gl-geocoder
@maplibre/maplibre-gl-draw	@mapbox/mapbox-gl-draw
maplibre-gl-compare	mapbox-gl-compare

Example:

javascript

// 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
  })
);

9. Everything Else Stays the Same

All your map code, events, layers, and sources work identically:

javascript

// 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 });

What Changes: Summary

Must change:

• Package name (maplibre-gl -> mapbox-gl)
• Import statements
• Add mapboxgl.accessToken configuration
• Style URL (switch to mapbox:// styles)
• Plugin packages (if used)

Stays exactly the same:

• All map methods (setCenter, setZoom, fitBounds, flyTo, etc.)
• All event handling (map.on('click'), map.on('load'), etc.)
• Marker/Popup APIs (100% compatible)
• Layer/source APIs (100% compatible)
• GeoJSON handling
• Custom styling and expressions
• Controls (Navigation, Geolocate, Scale, etc.)

Common Migration Issues

Issue 1: Token Not Set

Problem:

javascript

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

Solution:

javascript

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

Issue 2: Token in Git

Problem:

javascript

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

Solution:

javascript

// 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

Issue 3: Wrong Style URL Format

Problem:

javascript

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

Solution:

javascript

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

Issue 4: Plugin Compatibility

Problem:

javascript

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

Solution:

javascript

// 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:

javascript

// Wrong CDN
<script src="https://unpkg.com/maplibre-gl@3.0.0/dist/maplibre-gl.js"></script>

Solution:

javascript

// Use Mapbox CDN
<script src='https://api.mapbox.com/mapbox-gl-js/v3.0.0/mapbox-gl.js'></script>
<link href='https://api.mapbox.com/mapbox-gl-js/v3.0.0/mapbox-gl.css' rel='stylesheet' />

Migration Checklist

• Create Mapbox account and get access token
• Update package: npm install mapbox-gl (remove maplibre-gl)
• Update imports: maplibre-gl -> mapbox-gl
• Update CSS imports: maplibre-gl.css -> mapbox-gl.css
• Add token: Set mapboxgl.accessToken = 'pk.xxx'
• Use environment variables: Store token in .env
• Update style URL: Change to mapbox://styles/mapbox/streets-v12
• Update all references: Replace maplibregl. with mapboxgl.
• Update plugins: Install Mapbox versions of plugins (if used)
• Configure token security: Add URL restrictions in dashboard
• Test all functionality: Verify map loads, interactions work
• Set up billing alerts: Monitor usage in Mapbox dashboard
• Update documentation: Document token setup for team
• Add .env to .gitignore: Ensure tokens not committed

Quick Reference

Key Differences Summary

What	MapLibre	Mapbox
Package	maplibre-gl	mapbox-gl
Import	import maplibregl from 'maplibre-gl'	import mapboxgl from 'mapbox-gl'
Token	Optional (depends on tiles)	Required: mapboxgl.accessToken = 'pk.xxx'
Style	Custom URL or OSM tiles	mapbox://styles/mapbox/streets-v12
License	BSD (Open Source)	Proprietary (v2+)
Support	Community	Official commercial support
Tiles	Requires tile source	Premium Mapbox tiles included
APIs	Third-party	Full Mapbox API ecosystem
API	~95% compatible	~95% compatible

Bottom line: Migration is easy because APIs are nearly identical. Main changes are packaging, token setup, and style URLs. The result is access to Mapbox's premium tiles, ecosystem, and support.
