Mapbox GL JS can cluster thousands of points entirely in the browser with cluster: true — no server required. Here's a working setup, the click-to-expand pattern, and the dataset size where you must switch to server-side aggregation.
How to render large geospatial datasets in the browser with Mapbox GL JS vector tiles: a worked addSource/addLayer configuration, zoom‑dependent styling, runtime filters, and the silent failures that cause blank maps.
A Mapbox GL JS vector source that loads no tiles and throws no errors usually means a CRS mismatch or a broken tile URL template. Here's how to tell them apart and fix each.
Learn how to implement client-side point clustering in Mapbox GL JS to handle high-density datasets using GeoJSON sources, data-driven styling, and interactive zoom-to-expand functionality.
Feature-state restyles a feature on hover without resending geometry — but it silently does nothing when features have no id. Here's the mechanism, a worked pattern, and the trade-offs.
Learn how to use Mapbox GL JS vector tile filtering and the Expression API to reduce render overhead and create high‑performance, dynamic geospatial dashboards.
Learn when to use Vector Tiles versus GeoJSON sources in Mapbox GL JS to maintain 60fps performance when visualizing high‑density geographic datasets.
Integrating Mapbox GL JS v2+ within a React 18 environment introduces a conflict between React's declarative state management and Mapbox's imperative API. While wrappers like react-map-gl provide a useMap hook, maintaining a single source of truth for the viewport (center, zoom, and bearing) becomes complex when using external state managers such as Redux or
Mapbox GL JS v2.x tile cache persistence across token migration Goal Configure a mapbox-gl-js application to maintain seamless tile availability during access token migration without visible loading gaps or tile reloads for users currently viewing the map. Constraints Application uses mapbox-gl-js version 2.x with existing tilecache directory configuration U
