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> |

data-view-byte-offset 
Get the byteOffset out of a DataView, robustly.
This will work in node <= 0.10 and < 0.11.4, where there's no prototype accessor, only a nonconfigurable own property.
It will also work in modern engines where DataView.prototype.byteOffset has been deleted after this module has loaded.
Example
const dataViewByteOffset = require('data-view-byte-offset');
const assert = require('assert');
const ab = new ArrayBuffer(42);
const dv = new DataView(ab, 2);
assert.equal(dataViewByteOffset(dv), 2);
Tests
Simply clone the repo, npm install, and run npm test
