You can develop an extended feature as a Geolonia Embed Plugin. Geolonia Embed Plugin should be just a function.
To define a plugin, call window.registerPlugin(yourPlugin)
.
More detailed features are described below as the TypeScript section.
import * as Geolonia from "@geolonia/embed";
const myPlugin: Geolonia.EmbedPlugin = (
map: Geolonia.Map, // maplibregl.Map instance.
target: HTMLElement, // HTML Element. The Map will be rendered here.
atts: Geolonia.EmbedAttributes // data-x attributes specified at target element.
) => {
/* Do anything with those arguments. */
};
// be sure to register plugin.
window.geolonia.registerPlugin(myPlugin);
Load the plugins after loading Embed API.
