18 components now use withProps(HTMLElement, PROPS) instead of
repeating TypedBase cast, static get observedAttributes(), and
static { definePropAccessors(...) } in each file.
Adds src/core/with-props.ts — a mixin factory that derives
PropTypesFromTable, defines property accessors, and sets up
observedAttributes from a PROPS table in a single expression.
All 17 TypedBase components now share a single definePropAccessors(proto, PROPS)
call in their static block instead of duplicating the getter/setter loop.
Also includes pre-existing cleanup:
- Refine LeafletRegisterEvent type (interface -> generic CustomEvent)
- Drop unused attrToPropName helper
- Fix createChildRegisterHandler return type in layer-group/feature-group
Remove LeafletElement and LeafletControl base classes. Every component
now self-describes its attributes via a PROPS table, derives observed-
Attributes from it, and generates prototype getters/setters in static {}.
Registration lifecycle is extracted into standalone helpers
(registerWithParent, createChildRegisterHandler). Common update
patterns (path style) are shared via imported helpers instead of
duplicated across 5+ components.
Components manage their own #obj private field instead of a shared
protected leafletObject. Leaflet-map-style declarative patterns are
now consistent across all 20 components.
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.
