Polyfill for removed methods / options in Leaflet V2

May 18, 2025 ยท View on GitHub

Just include the Javascript file into your project and make L available in the window object.

Module:

<script type="module">
    import L from 'leaflet';
    window.L = L;
    import './leaflet-v1-polyfill.js';

    // Add the polyfills
    applyAllPolyfills();

Vanilla Script:

<script src="leaflet-global-src.js"></script>
<script src="leaflet-v1-polyfill.js"></script>
<script>
    // Add the polyfills
    applyAllPolyfills();

The different Polyfills

Bundles:

  • applyAllPolyfills()
  • applyMinimumPolyfills() (MouseEvents, Factory Methods) - should be enough for the most small plugins

Polyfills:

  • applyBrowserPolyfill()
  • applyDomUtilPolyfill()
  • applyUtilPolyfill()
  • applyMouseEventPolyfill()
  • applyDomEventPolyfill()
  • applyDeprecatedMethodsPolyfill()
  • applyFactoryMethodsPolyfill()
  • applyMiscPolyfill()
