Simple GeoJSON decoder library for ReScript based on @glennsl/rescript-json-combinators.

Example

let json = %raw(`{
    type: 'Feature',
    geometry: {
        type: 'Polygon',
        coordinates: [
            [
                [-180.0, 10.0],
                [20.0, 90.0],
                [180.0, -5.0],
                [-30.0, -90.0],
            ],
        ],
    },
    properties: null,
}`)
switch json->Json.decode(GeoJSON.Decode.object) {
| Ok(Feature({geometry: Polygon({coordinates})})) => Js.log2("Polygon coordinates: ", coordinates)
| Ok(_) => Js.log("not a feature with polygon?!")
| Error(err) => Js.log(err)
}

Installation
