Mapbox Store Locator Patterns

This is a solid reference for building any kind of location finder with Mapbox. It walks through the full stack: GeoJSON structure, marker strategies based on count (HTML markers under 100 locations, symbol layers for 100-1000, clustering beyond that), interactive sidebars, and distance calculations with Turf.js. The guidance on when to use GPU-rendered symbol layers versus DOM markers is especially practical, and the code samples cover the annoying details like syncing map clicks with sidebar scrolling. If you're building a store locator, restaurant finder, or office directory, this gives you the patterns to avoid reinventing everything from scratch.
