@mapbox/tile-decorator v4.0.0

tile-decorator

A JavaScript module for decoding Mapbox vector tiles, doing various modifications in JS and reencoding back. It can:

• add new properties to a layer (updateLayerProperties)
• filter out features that don't have specific properties (filterLayerByKeys)
• select properties to keep on each feature (selectLayerKeys)
• merge features with the same properties and type into one, and sort geometries within one feature by proximity for better compression (mergeLayer)
• get all values of a specific property in a layer (getLayerValues)
• rename layers (layer.name = 'foo')
• rename keys (layer.keys[2] = 'kittens')
