I am currently working on a project called angular2-google-maps-test and I am interested in integrating and expanding upon the JS library found at js-marker-clusterer
npm install --save js-marker-clustererIt seems that this library is not structured as a module.
function MarkerClusterer(map, opt_markers, opt_options) {
// MarkerClusterer implements google.maps.OverlayView interface. We use the
// extend function to extend MarkerClusterer with google.maps.OverlayView
// because it might not always be available when the code is defined so we
// look for it at the last possible moment. If it doesn't exist now then
// there is no point going ahead :)
this.extend(MarkerClusterer, google.maps.OverlayView);
this.map_ = map;
...
}
window['MarkerClusterer'] = MarkerClusterer;
My goal is to achieve something similar to this:
// js-marker-clusterer.d.ts file
declare module "js-marker-clusterer" {
export class MarkerClusterer {
constructor(map: any, opt_markers?: any, opt_options?: any);
map_: any;
markers_: any[];
clusters_: any[];
ready_: boolean;
addMarkers(markers: any[], opt_nodraw: boolean) : void;
removeMarker(marker: any, opt_nodraw: boolean) : boolean;
removeMarkers(markers: any[], opt_nodraw: boolean) : boolean;
}
}
Then, I plan to extend that class in TypeScript
/// <reference path="./js-marker-clusterer.d.ts" />
export class MyMarkerClusterer extends MarkerClusterer {
constructor(map: any, opt_markers?: any, opt_options?: any) {
super(map, opt_markers, opt_options);
}
}
However, when using rollupjs, I keep encountering this error:
[21:20:47] bundle failed: 'MarkerClusterer' is not exported by node_modules/js-marker-clusterer/src/markerclusterer.js MEM: 469.6MB
(imported by src/angular2-marker-clusterer/my-marker-clusterer.ts). For help fixing this
error see https://github.com/rollup/rollup/wiki/Troubleshooting#name-is-not-exported-by-module
My assumption is that I need to make modifications to the rollup.config.js file, but my attempts to add it as a plugin have been unsuccessful.
