protomaps-leaflet
Vector tile rendering and labeling for Leaflet.
This project is a complete vector tile renderer - including quality label layout - in as simple as possible of an implementation. It’s an alternative to renderers like MapLibre GL JS in a fraction of the size.
New projects starting from scratch should probably use MapLibre GL, but this library is useful as a drop-in replacement for raster basemaps in Leaflet, either using the Protomaps API or PMTiles on your own storage.
Features
- Render interactive slippy maps with Leaflet integration
- Supports variable web fonts with multiple weights and italics in a single font file
- Can read normal Z/X/Y tile URLs or offline, static-hosted tile archives in PMTiles format
- Full out-of-the-box support for right-to-left and Indic/Brahmic writing systems
- Configurable via plain JavaScript
- (Advanced) Extensible API for defining your own symbolizers
