leptos-leaflet

Leaflet components for Leptos. This aims to target the functionality of React-Leaflet.

For now only a few of the components are ported, and events must be set in the Signal map object set by the MapContainer when leaflet is inited.

NOTE: Current version support leptos 0.6.x, that removes all Scope usages from signals and effects.

Support for leptos 0.7.x exists in the leptos-0.7 branch. When Leptos 0.7 is released, this branch will be merged into main.
