Can we have a feature that can get source's meta info to know the layer id and layer type when add a unknown vector tile services?

Can we have a feature that can get source's meta info to list layers's id and layer's type when add a unknown vector tile service? I think these can help us to style vector service in right way,and can made a default style for different layers (point--circle,polygon--fill,line--line).

Unfortunately there is no standard way to list all the layers in a vector tile source. Mapbox sources provide a vector_layers object in their TileJSON but because this feature is not standard, it is not available within the GL JS API.

You can call map.getStyle().layers to find the layers defined in the current style.

Here is how you can get the id and the type of each layer:

var map = new mapboxgl.Map({
    container: 'map',
    style: 'mapbox://styles/mapbox/light-v9',
    zoom: 13,
    center: [-122.447303, 37.753574]
});

map.on('load', function () {    
    var layersMeta = map.getStyle().layers
        .map(function(layer) { 
            return [layer.id, layer.type];
        });
   console.log(layersMeta);   
});

And here's the corresponding jsfiddle. Have a look at the console.
