Every component is now two modules sharing a basename:
- src/elements/leaflet-foo.ts -- `export default class LeafletFooElement
extends WithProps(...)`, the class only, no customElements.define, no
side effects. src/elements/index.ts is an order-free barrel.
- src/components/leaflet-foo.ts -- three lines: import the class, define
the tag, re-export. Importing this (or src/index.ts) registers the tag.
Plugin authors can now import a class without triggering the built-in
define, to subclass it or register it under a different tag name. Package
subpath exports `leaflet-components/elements`,
`leaflet-components/elements/leaflet-foo.js`, and
`leaflet-components/components/leaflet-foo.js` map onto dist/; jsr.json
gains an `./elements` entry.
The load-bearing ordering moves from the export statements in src/index.ts
to its `./components/*` side-effect imports (the elements barrel carries no
define, so its order is free). Classes are renamed LeafletFoo ->
LeafletFooElement, including in the HTMLElementTagNameMap augmentation.
Docs (CLAUDE.md, docs/, README.md) updated for the new layout.
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.
