Vite + TypeScript PWA that mirrors the Android app's core features: - Pre-processed shelter data (build-time UTM33N→WGS84 conversion) - Leaflet map with shelter markers, user location, and offline tiles - Canvas compass arrow (ported from DirectionArrowView.kt) - IndexedDB shelter cache with 7-day staleness check - Service worker with CacheFirst tiles and precached app shell - i18n for en, nb, nn (ported from Android strings.xml) - iOS/Android compass handling with low-pass filter - Respects user map interaction (no auto-snap on pan/zoom) - Build revision cache-breaker for reliable SW updates Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

/**
|
|
* This method is like `_.intersection` except that it accepts `iteratee`
|
|
* which is invoked for each element of each `arrays` to generate the criterion
|
|
* by which they're compared. The order and references of result values are
|
|
* determined by the first array. The iteratee is invoked with one argument:
|
|
* (value).
|
|
*
|
|
* @static
|
|
* @memberOf _
|
|
* @since 4.0.0
|
|
* @category Array
|
|
* @param {...Array} [arrays] The arrays to inspect.
|
|
* @param {Function} [iteratee=_.identity] The iteratee invoked per element.
|
|
* @returns {Array} Returns the new array of intersecting values.
|
|
* @example
|
|
*
|
|
* _.intersectionBy([2.1, 1.2], [2.3, 3.4], Math.floor);
|
|
* // => [2.1]
|
|
*
|
|
* // The `_.property` iteratee shorthand.
|
|
* _.intersectionBy([{ 'x': 1 }], [{ 'x': 2 }, { 'x': 1 }], 'x');
|
|
* // => [{ 'x': 1 }]
