Leaflet prunecluster permanent tooltip problem and solution

Prunecluster is a nice plugin for Leaflet for realtime clustering.

However, if you use permanent tooltips on markers, the label will not disappear when you zoom.
You can fix the problem by adding a codeline, see below:

    Unspiderfy: function () {
        var _this = this;
        for (var i = 0, l = this._currentMarkers.length; i < l; ++i) {
            this._currentMarkers[i].unbindTooltip(); // This line is added to remove permanent tooltips.
            this._currentMarkers[i].setLatLng(this._currentCenter).setOpacity(0);
        }

npm: self signed certificate in certificate chain

Deze melding krijg je als de certificaten niet gecontroleerd kunnen worden op je nexus server. Vervelend, maar op te lossen als je doet:
npm config set strict-ssl false --global
