Prepare your environment with:
nvm use
npm ci
To generate style.json files in all themes and supported languages, run:
npm run generate-styles https://example.com/your-tilejson-url.json
Note that you have to replace the TileJSON URL with your own.
This will create files in the dist/styles/
folder like this:
dist/
styles/
light/
ar.json
bg.json
