Replace Number(x) with +x, String(x) with template literal,
parseInt(x, 10) with +, and parseFloat(x || "0") with +(x ?? 0).
Fix operator precedence with parentheses around ?? expressions.
Merge path-style.ts and with-props.ts into utils.ts to reduce the
number of core files from 5 to 3 (utils.ts, props.ts, register.ts).
Unify duplicate ../core/utils.ts imports in all component files.
Remove stale re-exports from src/index.ts.
Make NumProp and BoolOffProp generic (NumProp<T>, BoolOffProp<T>)
instead of using any, with T inferred from callback parameters at
call sites via the num<T>() and off<T>() factory helpers. Remove
unused num import from leaflet-tile-layer-wms. Fix prettier
formatting issues.
Extend num() factory to accept optional extra fields (mapGet, mapSet,
viewState, event). Add off() factory and BoolOffPropInput type. Update
defineProps to derive disable- prefix for bool-off attrs. Remove
~40 lines of local type definitions from leaflet-map.ts.
All 21 component files export exactly one class. Change to
export default so consumers can import them without named braces.
Update src/index.ts re-exports from "export *" to
"export { default as LeafletXxx }". Fix the two type-only
imports of LeafletLine to use default import syntax.
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.
Replace the height-attribute approach with a ResizeObserver on the host
element so the map re-renders whenever its container size changes from
any source — CSS class, inline style, parent layout, etc.
Replace inline CSS import with a configurable CDN <link> to fix 404s on
marker icon PNG files (relative paths now resolve against the CDN URL).
- Remove leaflet/dist/leaflet.css import and --loader:.css=text from build
- Add css-url, css-integrity, css-crossorigin attributes on <leaflet-map>
- Derive Icon.Default.imagePath from CSS URL for JS-loaded marker icons
- Move shadow DOM setup into connectedCallback with reconnection guard
- Use CSS_ATTRS constant for observedAttributes and attributeChangedCallback
CSS attrs default to https://unpkg.com/leaflet@1.9.4/dist/leaflet.css with
SRI integrity and crossorigin='anonymous'. Custom CSS URLs drop the
default integrity; set css-integrity explicitly to re-enable SRI.
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.
