Leaflet plugin to support pre-loading tiles outside the current viewport. It will be compatible with Leaflet master once a change to support a GridLayer tile bounds hook is merged.
Include Leaflet.EdgeBuffer.js, then add edgeBufferTiles: 1 to the options of layers you wish to have an edge buffer.
- edgeBufferTiles: (number) The number of tiles that should be loaded beyond the edge of the map viewport. This may be a fractional number. Default to undefined, which disabled the feature.
This demo shows two maps, one without this plugin active and one with.
