基于外部JS创建绑定

API是作为全局安装的,因此 bind to them as ordinary globals . 而且,由于reason函数生成普通的javascript函数,因此以下内容或多或少相当于您链接的文档中的示例:

type map;
[@bs.new] [@bs.scope ("google", "maps")] external make : (Dom.element, Js.t({..})) => map = "Map";

let initMap = () => {
  let map = make(mapElement, {
    "center": { "lat": -34.397, "lng": 150.644 },
    "zoom": 0
  });
};
