Randy Fischer b005193dbc Request persistent storage after first save IndexedDB data can be evicted under storage pressure, especially on iOS Safari. navigator.storage.persist() asks the browser to keep our data. On Chromium+Firefox it succeeds silently when conditions allow (installed PWA, engagement heuristics); on Safari it typically grants only for installed PWAs. - persistentStorage.js: isPersisted() and requestPersistence() with graceful fallback when the Storage API is unavailable. - persistence.js: request persistence once, after the first successful save — a heuristic that works across Firefox (user gesture context) and Chromium/Safari (data-stored context). - sw.js: bump cache version, precache new file. - index.html: load new script.		2026-04-15 15:54:06 +02:00

Uitvoeren

Snel testen (geen PWA-functionaliteit): Dubbelklik public/index.html. Werkt vanaf file://.

Volledige PWA (service worker + installatie): Start een webserver vanuit 01_Applicatie/ en open de app via http://localhost:<poort>/public/:

python -m http.server 8000
# open http://localhost:8000/public/

Service worker, installatieknop en offline-caching werken alleen vanaf http(s):// of localhost — niet vanaf file://.

Branches

master — live productie (auto-deploy bij merge)
develop — staging (auto-deploy bij merge)
feature branches — nieuwe functionaliteit, merge via PR in develop
