QUESTION
I'm trying to use MarkerClusterGroup on a leaflet map. I have the error L.MarkerClusterGroup is not a function. I've read the related threads, but they are only valid for versions below leaflet 1.7.
I'm using React with webpack.
...ANSWER
Answered 2022-Mar-22 at 14:43Depending on your build engine, the imported L namespace from "leaflet" may not be augmented with MarkerClusterGroup (from leaflet.markercluster plugin) unfortunately.
But you can resort to using window.L instead, which is always augmented by the plugin.
BTW, either use the class constructor form with new keyword: new window.L.MarkerClusterGroup(), or use the factory form with lowerCamelCase: L.markerClusterGroup()
QUESTION
I am trying to update an Angular project from version 12 to 13. I am following the guidance from the Angular update website https://update.angular.io/?v=12.0-13.0 .
This is the package.json before the upgrade process started
...ANSWER
Answered 2022-Mar-09 at 07:50It might be because of package-lock.json file is not updated with the latest versions of Angular.
I am able to solve this problem by deleting package-lock.json file and running npm install again.
As my project is new, no problem in deleting package-lock.json file be careful while deleting this file it might cause other issues.
QUESTION
I'm doing a Leaflet map with some GeoJSON data.
I try to add the cluster function to my JS file. As I added some filter and styling features according to properties, I'm unable to find the right way to code the cluster fonction.
Here is the GeoJSON layer and the filter verificator:

Answered 2022-Jan-13 at 17:19Once you have populated your Leaflet GeoJSON Layer Group (typically with geojsonLayer.addData(geoJsonObject), then instead of adding that group to your map, simply add it into your MarkerClusterGroup:

QUESTION
Following the guide we upgraded angular 11 to 12. Before the upgrade karma is running the unit tests without any issues. However, after the upgrade this is what we end up with. Any idea how to check whats wrong.
I also compared the source with a refresh angular 12 project (karma works here), but changes did not make any difference.
...ANSWER
Answered 2021-Aug-17 at 12:36Did you ensure that the versions of karma, karma-chrome-launcher, karma-cli, karma-firefox-launcher, (all other karma packages) and jasmine packages were the same between the fresh Angular 12 version and your project? And then did you run a fresh npm install after making sure the versions are the same?
After that, try comparing test.ts, angular.json and tsconfig.spec.json between the fresh project and your project to ensure they are the same.

I am using bootstrap modal but I noticed that since I changed and added further bootstrap downloaded files, it has stopped working. It may not be the script tags causing it, but I noticed that up until then, it was working.
I also added the bootstrap courousal but I have removed it now, and it still isnt showing (the modal)
No errors are showing in the console.
I have included my code below;

...ANSWER

jQuery should usually come first, or at least included before Bootstrap, followed by other plugins that usually depend on them with your own scripts coming in at last.
If the modals still don't work, please share your Bootstrap version details.
QUESTION
Not sure how I have managed this but my leaflet zoom controls are not clickable? They do show up on the screen but there is no mouse change when hovering over them.
Do I need to create another layer for the controls or am I missing something else from my code?
update: The map will also not scroll or zoom in - it appears static
This is my script relating to the map:

QUESTION
TLDR; Is there a way to clear all markers from a marker cluster using react-leaflet and react-leaflet-markercluster?
EDIT: Yes, there is! I just added a key prop to the MarkerClusterGroup, as @SethLutske recommended. Now, every time there is a re-render of the map, the previous markers are removed and only the new ones remain.
...ANSWER
Answered 2021-May-26 at 20:18You can add a key prop to MarkerClusterGroup, and change it when you want the cluster to be completely rerendered.
QUESTION
In my current Hybrid app I am in the process of switching from using Leaflet and its Clusterer plugin to using the HERE Maps v3 JavaScript API. The HERE Maps documentation can be rather dense at times for someone used to the clarity of Leaflet documentation. Nevertheless the process of using HERE is fairly straightforward. However, there is one Leaflet feature that I really miss:
In Leaflet when you add markers to a cluster it is possible to assign custom map pins to each marker. Further, you can quite easily customize the pin used to represent the cluster itself. In HERE the documentation indicates the following
...ANSWER
Answered 2021-Feb-12 at 11:01Clusters and noise points are represented on the map with markers. Unless otherwise configured, the clustering provider uses the default bitmap markers theme with weight information to display clusters and noise points on the map. You can define your own custom theme and pass it to the provider as the theme property.
Read please this docu on https://developer.here.com/documentation/maps/3.1.22.0/dev_guide/topics/clustering.html
A custom theme is defined in an object that implements the interface H.clustering.ITheme as demonstrated by the code below.
