Question 1

How do I add custom markers to a Mapbox GL JS map?

Accepted Answer

Use the Marker API by creating a new mapboxgl.Marker instance, setting its element to custom HTML or an image, and adding it to the map. The documentation provides examples with popups and event handling for interactive features.

Question 2

Mapbox GL JS or Leaflet: which should I use for my project?

Accepted Answer

Choose Mapbox GL JS for high-performance vector maps with WebGL rendering and deep customization via style specs. Leaflet is better for simpler, raster-based maps with a lighter footprint and easier setup for basic use cases.

Question 3

Is Mapbox GL JS free to use?

Accepted Answer

It has a free tier with usage limits, but beyond that, it requires a paid Mapbox account based on map loads and services. Always check the latest pricing on Mapbox's website as the license ties usage to an active account.

Question 4

How can I style my map in Mapbox GL JS?

Accepted Answer

Define styles using the Mapbox Style Specification JSON, which controls layers, sources, and properties. You can use Mapbox Studio or write custom code to apply unique colors, icons, and 3D effects as shown in the examples gallery.

Question 5

Can I use Mapbox GL JS with React?

Accepted Answer

Yes, via wrappers like react-map-gl or by integrating it directly. Mapbox provides React Native support, and the community has libraries for seamless React integration, ensuring compatibility with modern web frameworks.

Question 6

What browsers does Mapbox GL JS support?

Accepted Answer

It supports modern browsers with WebGL, including Chrome, Firefox, Safari, and Edge. Older browsers like IE 11 may have limited or no support, so check the compatibility documentation for specific versions.
