I can use this extension in angular?

[souzaemmanuel]

I installed the dependency via npm but I was unable to use the properties of the semicircle.

Some help?

Ok, I found the correct way to draw semicircles. The problem was that in addition to installing the Leaflet-semicircle extension via npm I needed to import the javascript file properly.

Just follow the steps:

  npm i leaflet --save  
    npm install --save leaflet-semicircle

In angular.json file add the libraries as follows:

    "scripts": [
          "node_modules/leaflet/dist/leaflet.js",
          "./node_modules/leaflet-semicircle/semicircle.js"
      ]

And finaly, the problem was here:

    import 'leaflet';
    import 'leaflet-semicircle';

    //Right way to import and extend all extensions importeds previously
    declare let L;

    //Doesn't works */
    //import * as L from 'leaflet';
