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?

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

Aspect	Mapbox GL JS	MapLibre GL JS
License	Proprietary (v2+)	BSD 3-Clause (Open Source)
Support

Official commercial support | Community support | | Tiles | Premium Mapbox vector tiles | OSM or custom tile sources | | Satellite | High-quality global imagery | Requires custom source | | Token | Required (access token) | Optional (depends on tile source) | | APIs | Full Mapbox ecosystem | Requires third-party services | | Studio | Full integration | No native integration | | 3D Terrain | Built-in with premium data | Available (requires data source) | | Globe View | v2.9+ | v3.0+ | | API Compatibility | ~95% compatible with MapLibre | ~95% compatible with Mapbox | | Bundle Size | ~500KB | ~450KB | | Setup Complexity | Easy (just add token) | Requires tile source setup |

Step-by-Step Migration

1. Create Mapbox Account

1. 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

CODEBLOCK0

3. Update Imports

CODEBLOCK1

Or with CDN:

CODEBLOCK2

4. Add Access Token

CODEBLOCK3

Token best practices:

• - Use environment variables: process.env.VITE_MAPBOX_TOKEN or INLINECODE2
• 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

CODEBLOCK4

6. Update Style URL

Mapbox provides professionally designed, maintained styles:

CODEBLOCK5

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

CODEBLOCK6

7. Update All References

Replace all maplibregl references with mapboxgl:

CODEBLOCK7

8. Update Plugins (If Used)

Some MapLibre plugins should be replaced with Mapbox versions:

MapLibre Plugin	Mapbox Alternative
INLINECODE9	INLINECODE10
INLINECODE11

@mapbox/mapbox-gl-draw |
| maplibre-gl-compare | mapbox-gl-compare |

Example:

CODEBLOCK8

9. Everything Else Stays the Same

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

CODEBLOCK9

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:

CODEBLOCK10

Solution:

CODEBLOCK11

Issue 2: Token in Git

Problem:

CODEBLOCK12

Solution:

CODEBLOCK13

Issue 3: Wrong Style URL Format

Problem:

CODEBLOCK14

Solution:

CODEBLOCK15

Issue 4: Plugin Compatibility

Problem:

CODEBLOCK16

Solution:

CODEBLOCK17

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:

CODEBLOCK18

Solution:

CODEBLOCK19

Migration Checklist

• - [ ] Create Mapbox account and get access token
• [ ] Update package: npm install mapbox-gl (remove maplibre-gl)
• [ ] Update imports: maplibre-gl -> INLINECODE29
• [ ] Update CSS imports: maplibre-gl.css -> INLINECODE31
• [ ] Add token: Set INLINECODE32
• [ ] Use environment variables: Store token in INLINECODE33
• [ ] Update style URL: Change to INLINECODE34
• [ ] Update all references: Replace maplibregl. with INLINECODE36
• [ ] 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	INLINECODE37	INLINECODE38
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.
