- leaflet moves from `dependencies` to `peerDependencies` (^1.9.4), kept in
`devDependencies` for local dev/tests. The nesting protocol dispatches on
`instanceof` against Leaflet's own Layer/Popup/Tooltip, so a second copy
pulled in transitively would silently break child registration.
- `@types/leaflet` (and its `@types/geojson` dep, imported directly by
leaflet-geojson's emitted .d.ts) move to `dependencies` — the published
declarations reference them and `leaflet` ships no types of its own, so a
TS consumer had a broken type surface with nothing signalling why.
- Drop the `exports["./dist/*"]` wildcard: it exposed the whole internal
tree (`core/*`, explicitly "not a stable contract") as importable,
semver-relevant surface. Root + `./elements` + `./components/*.js` cover
every intended entry.
- `prepublishOnly` now runs `typecheck` + `test` + `build`, not just `build`.
Verified against a packed tarball: a fresh consumer with only the declared
deps present typechecks clean under `moduleResolution` bundler and nodenext.
CLAUDE.md / docs / README updated to match.
Replace prettier with oxfmt (oxc's Prettier-compatible formatter), config
seeded via `oxfmt --migrate=prettier` and kept as `oxfmt.config.ts`
(defineConfig default export) so settings match the old prettier.config.js.
The `format` script now runs `oxfmt`; docs and the local tool allowlist
updated to match.
No test coverage existed before this. Adds vitest + jsdom (2 new
devDependencies) and a suite that runs entirely without a browser: real
Leaflet objects work fine under jsdom for everything this library needs to
verify (option/attribute wiring, event forwarding), given a ResizeObserver
stub in test/setup.ts (jsdom's only real gap here).
- test/core/with-props.test.ts: the WithProps mixin itself, against a fake
Leaflet-like class -- attribute<->setter dispatch, get/attribute/default
fallback order, event-driven attribute sync-back, positional/recreate/
attach modes, and the generic fire()-patch event forwarding. Child
registration (popup/tooltip/layer binding) uses real Popup/Tooltip/Marker
instances since #onChildRegister discriminates by instanceof.
- test/core/props.test.ts: the codec functions in isolation.
- test/components/*.test.ts: grouped smoke tests across all components.
- test/integration.test.ts: full tree wiring (map + tile-layer +
feature-group + marker + popup).
Caught and fixed one real bug along the way: urlProp's "live url getter"
from the last refactor was dead code -- neither ImageOverlay nor
VideoOverlay actually expose getUrl(). Removed it and the now-pointless
getUrl?() from the Sourced interface in shared-props.ts.
tsconfig.test.json keeps test/ out of the tsc build (dist/ stays
test-free) while still typechecking it; oxlint.config.ts now covers test/
too, with max-classes-per-file relaxed there since testing a class
factory means many small one-off element classes.

Finishes the WithProps(PROPS, options) mixin (src/core/with-props.ts): every
component gets reactive attributes, live-value property getters that read
through to the Leaflet object where possible, and every Leaflet event
re-emitted on the element as `leaflet:<type>` via a generic fire() patch (no
per-component or per-event registration needed).
Prop coverage:
- Centralized pathProps in shared-props.ts (stroke, lineCap, lineJoin,
dashArray, dashOffset, fillRule, interactive, className,
bubblingMouseEvents, pane), deduped leaflet-geojson against it.
- Added live getters backed by Leaflet's own accessors: radius (circle,
circle-marker), bounds (rectangle, image/video/svg-overlay), url
(image/video-overlay).
- Filled gaps: smoothFactor/noClip on polyline; a shared tileLayerProps
fragment now used by both tile-layer and tile-layer-wms (WMS previously
exposed none of its base tile options); crs on WMS; zIndex/className/
keepAspectRatio/errorOverlayUrl on video-overlay; fixed tile-layer's
zIndex default and div-icon's className default to match Leaflet.
Tooling:
- Removed dead src/core/events.ts (broken, unused, superseded by the
generic event forwarding above) and src/core/attributes.ts (emptied by
an earlier rename, nothing imported it).
- Swapped ESLint + @typescript-eslint for oxlint: no released
@typescript-eslint version supports the pinned typescript@7, even for
parsing alone. oxlint has its own parser and lints clean.
- Dropped the Rollup CJS/UMD bundle step; dist/ is ESM-only from tsc now.
Updated package.json's main/module/exports/unpkg accordingly.
- Updated CLAUDE.md to match: build/lint commands, ESM-only output, the
event-forwarding mechanism, and layer-group/feature-group now going
through WithProps({}) instead of raw HTMLElement.
Upgrade ESLint config to use flat config with @typescript-eslint/strict-type-checked and stylistic-type-checked presets.
- Use defineConfig helper, scope to .ts files only
- Replace || with ??, convert type to interface, remove redundant type assertions and non-null assertions
- Annotate intentional violations (unbound-method, non-null-assertion) with eslint-disable
- Use querySelectorAll<T> for typed selection, Map over globalThis.Map
- Add @eslint/js dev dependency
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.
