- Strip leaflet-icon.ts to image-only (new Icon(), remove div/html/bgPos)
- Create leaflet-div-icon.ts with DivIcon, innerHTML content, MutationObserver
- Convert marker↔icon from querySelector to event-only protocol:
marker iterates children dispatching leaflet-request-icon on each,
icons listen on themselves and respond with icon-changed
- Extract emitIconChanged() helper into register.ts to eliminate
repeated CustomEvent construction across both icon components
- Type icon-changed and leaflet-request-icon in HTMLElementEventMap
- Update marker's #onIconChanged to use typed event instead of cast
- Export LeafletDivIcon from index.ts
- Add DivIcon demo markers to custom-icon.html and index.html
Every component now exposes a uniform get leafletObject() returning
the underlying Leaflet instance (undefined before connected).
Event wiring:
- Marker: listen for 'dragend move' via onChange, syncing lat/lng
back to attributes. Converted from arrow property to regular
method using Leaflet's 3rd context arg pattern.
- Circle, CircleMarker: listen for 'move' via onMove with syncing
guard (same pattern).
- Popup, Tooltip: listen for 'move' via onChange with syncing
guard and null-check on getLatLng().
Also:
- Update README with escape hatch section
- Change map getter from get map() to get leafletObject() for
consistency
- index.html: add importmap for leaflet
- All component exports changed from default to named
- index.ts re-exports updated accordingly
When adding a child to leaflet-map, the tag select is now grouped
into categories: Tile Layers, Markers, Shapes, Data, Overlays,
Groups, and Controls, using <optgroup> elements.
- Left pane: nested component tree with +/x buttons for add/remove
- Right pane: attribute editor with per-input MutationObserver sync
- Shared pick-on-map: single click picks both lat/lng from one map click
- Add-child wizard replaces editor pane, Cancel restores previous content
- Source HTML display for selected element
- Missing attributes added: min/max-zoom, zoom-snap/delta, path style attrs,
popup/tooltip lat/lng, overlay interactive/loop/autoplay, and more
Wraps Leaflet.js as native Web Components. Each element maps 1:1 to a
Leaflet object with reactive attribute binding and proper lifecycle cleanup.
Key design decisions:
- LeafletElement base class handles attribute→option mapping, the
leaflet-register bubble event for parent/child wiring, and
disconnectedCallback cleanup tracking parent bindings.
- LeafletControl base class for map controls (zoom, attribution, scale).
- leaflet-map uses a PROPS table to drive observedAttributes, getters/setters,
attributeChangedCallback, and map event listeners from a single source of
truth. Property types are derived via a mapped type over the table; the
mixin-base pattern (TypedBase) makes them visible to TypeScript without an
interface merge.
- Boolean map options that default to true use disable-* attributes.
- Leaflet and its CSS are bundled into dist/index.js via esbuild.
- JSR config included for @buddy/leaflet-components.
