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> |

globalThis 
An ECMAScript spec-compliant polyfill/shim for globalThis. Invoke its "shim" method to shim globalThis if it is unavailable.
This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec proposal.
Most common usage:
var globalThis = require('globalthis')(); // returns native globalThis if compliant
/* or */
var globalThis = require('globalthis/polyfill')(); // returns native globalThis if compliant
Example
var assert = require('assert');
// the below function is not CSP-compliant, but reliably gets the
// global object in sloppy mode in every engine.
var getGlobal = Function('return this');
assert.equal(globalThis, getGlobal());
/* when `globalThis` is not present */
var shimmedGlobal = require('globalthis').shim();
/* or */
var shimmedGlobal = require('globalthis/shim')();
assert.equal(shimmedGlobal, globalThis);
assert.equal(shimmedGlobal, getGlobal());
/* when `globalThis` is present */
var shimmedGlobal = require('globalthis').shim();
assert.equal(shimmedGlobal, globalThis);
assert.equal(shimmedGlobal, getGlobal());
