Change all import specifiers from ".js" to ".ts" in TypeScript source
files. Add allowImportingTsExtensions and rewriteRelativeImportExtensions
to tsconfig so tsc strips them to ".js" in the dist output — no build
pipeline changes needed. Update CLAUDE.md to reflect the new extension policy.
The types/ directory now only had a single file. The PropDef and
PropTypesFromTable types are foundational to the module infrastructure
(used by utils.ts, with-props.ts, and every component), so core/ is a
better home. Deleted the empty types/ directory.
- camelCase removed entirely (never imported anywhere)
- PATH_STYLE_ATTRS, ChildEntry, createChildRegisterHandler made private
(used only internally within their modules)
- src/types/css.d.ts deleted (leftover from an earlier
approach — no .css imports exist in the source)
Use a const type parameter on the exclude array so literal tuples narrow
correctly. The return type now reflects the actual properties and their
kinds (number/string/boolean) instead of Record<string, unknown>.
Four call sites needed local casts where PROPS declares str but Leaflet
expects a narrower type (crossOrigin, offset) — these are design-level
mismatches between HTML attribute types and Leaflet's option types.
Adds buildAttrMap(props) and setLayerAttr(obj, props, attrMap,
name, val) to utils.ts. The former replaces the PROP_BY_ATTR Map
construction (2 fewer lines per component), the latter replaces
the 6-line dynamic setter dispatch pattern used as the fallback
else block in 6 components.
For WMS, setLayerAttr returns false when no setter exists, so the
caller can fall back to setParams for non-method props.
Replaces the identical private #parsedBounds method in rectangle,
image-overlay, video-overlay, and svg-overlay with a call to
parseBoundsAttr(el) from utils.ts. Removes 4 x 5 = 20 lines
of method definitions.
Removes the identical private #num method from 5 components
(leaflet-circle, leaflet-circle-marker, leaflet-marker,
leaflet-popup, leaflet-tooltip). Replaces with numAttr(this, PROPS, name)
call to the new helper in utils.ts.
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
buildOptions was passing default values for absent attributes,
including empty-string defaults like pane:'', which caused Leaflet to
look up this._panes[''] and return undefined, crashing in appendChild.
- Skip empty-string defaults in buildOptions so Leaflet uses its own
- Broaden createChildRegisterHandler param from LayerGroup to Layer so
non-container layers (marker, circle, etc.) can intercept popup/tooltip
children and call bindPopup/bindTooltip instead of bubbling to the map
- Add child-registration handler to every layer component (all 12)
- Fix disconnectedCallback in container components to unbind popups and
tooltips and remove child layers properly
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.
