mapbox-gl-style-diff

Tool providing a semantic readout of diffs between "before" and "after" stylesheet states. Assumes stable layer id names.

Currently detects

changes to all parameters within each style layer
changes to the layer stack (new, removed, moved layers)
changes to sources (new, removed, updated sources)

To be implemented

changes to stylesheet parameters outside layers and sources
detecting renamed layers (in a way beyond showing them as removed and immediately readded)

Usage

bin/mapbox-gl-style-diff ./path/to/style/a.json ./path/to/style/b.json

Standalone tool

Currently you can also use this as a standalone tool via stamen-diff.html
