leaflet-store-locator
A responsive store locator based on the Mapbox JS example, tweaked to use Leaflet 1.0, Google Carto basemaps and custom icons. The sidebar uses a simple jQuery filter function (thanks jsfiddle). The nearest store function uses TurfJS, based loosely on this example, also from Mapbox. The production version uses surge.sh for deployment.
Stores are loaded via a stores.csv file in the assets/data/ folder. The search is done on the entire sidebar list, so this may not be the best option for extremely large data sets.
