OpenMapTiles language
This small javascript library adds support for changing language of OpenMapTiles-based maps displayed with Mapbox GL JS.

Place this code AFTER loading mapbox-gl-js:
<script src="https://cdn.klokantech.com/openmaptiles-language/v1.0/openmaptiles-language.js"></script>
API
When the script above is loaded, it adds these methods to every mapboxgl.Map instance:
map.setLanguage(languageCode, noAlternatives)languageCode- language to use (see https://github.com/openmaptiles/openmaptiles/blob/master/openmaptiles.yaml for the possible values); use"native"to show names in local languagesnoAlternatives(optional) - disable latin alternatives for non-latin languages (and vice-versa)
map.autodetectLanguage(fallback)- Automatically detects language from browser (
navigator.language) and uses that language fallback(optional) - language to use if detection was not successful
- Automatically detects language from browser (
