PMTiles is a single-file format for vector or raster map tiles. You host one (or a few) files on any static host; MapLibre requests byte ranges over HTTP. No tile server, no dynamic backend. This skill covers when to use PMTiles, how to generate and host them, and how to connect them to MapLibre GL JS.

MapLibre does not speak PMTiles natively. You use the PMTiles library to add a protocol handler so that a pmtiles:// (or https:// to a .pmtiles file) source works.

Referencing layers: The style has one source (e.g. sources.tiles) pointing at the .pmtiles URL. Each layer in the layers array that draws from that file uses source: 'tiles' and "source-layer": "layerName", where layerName is the name of a vector layer inside the file (from whatever schema the tiles use). Add multiple style layers with different source-layer values to show roads, labels, etc. from the same file.
