How to style GeoJSON layer according to embedded attributes

[rsurgiewicz]

Hi Folks,

I have a question. The datasource I'm using provides the full geojson data with attributes e.g

        "fill-opacity": 0.5,
        "stroke-width": 0.5,
        "stroke": "#8f8f8f"

and it is interpreted correctly e.g by geojson.io

How can I force maplibre-gl to use those styles, cause all I get is:

Thanks!

I assume you are talking about https://github.com/mapbox/simplestyle-spec/tree/master/1.1.0? this is not part of the geojson spec so talking about "full geojson data" is a bit misleading. It should be quite easy to make a style using expressions to support most of this properties (not sure about the marker ones). This would also make a nice documentation example as this could be a common use case.

Ok finally I got it right.
Actually there's a possibility to use get feature to grab value from data.

so in my example

...      },
      "properties": {
        "fill": "#18ff00",
        "fill-opacity": 0.5,
        "stroke-width": 0.5,
        "stroke": "#8f8f8f"
      }

it would be something like:

  id: "data",
  type: "fill",
  paint: {
    "fill-color": ["get", "fill"],
    "fill-opacity": 0.8,
  },
};
