Geojson Component

In order to limit dependencies for reason-react-native-maps, a ready-to-use Geojson component is not provided. Instead, a suitable instance of the Geojson.Make module needs to be created, as below, specifying the type for the geojson prop:

YourModule.re

include ReactNativeMaps.Geojson.Make({
  type t = someType;
});

While you may define your own type, for type safe handling of GeoJSON objects, you may use the types defined in the GeoReason package. In that case, the relevant type is GeoReason.Data.t and the instance can be created as below:

YourModule.re

include ReactNativeMaps.Geojson.Make({
  type t = GeoReason.Data.t;
});

Please make sure to follow installation instructions for GeoReason and update bsconfig.json accordingly for your project.

Once created, the module would be used as below:

<YourModule
  geojson=someValue
/>

Please note that only the FeatureCollection(list(Feature.t)) variant will be valid for use with your component.

An instance of the module may be created within your module, as a submodule, as below:

YourModule.re

module Geojson = ReactNativeMaps.Geojson.Make({
  type t = someType;
});

in which case the module would be used as below:

<YourModule.Geojson
  geojson=someValue
/>
