Connect installs on desktop, iPhone, iPad and Android with a standalone interface, push notifications and controlled updates.
Public PWA resources, installation interface and service-worker tests.
iOS installation uses Safari rather than the App Store.
Explicit cache allowlist plus offline and update checks.
Offline mode does not expose arbitrarily stale operational history; unsent messages use a local outbox.
VAPID configuration, subscription endpoints, a default without message preview, and negative revocation and incoming-call push tests.
iOS push requires an installed Home Screen app and explicit permission; delivery remains under OS control.
Desktop uses three information columns, tablet reduces deliberately and mobile becomes a focused single-column app with safe-area support.
Supported browsers install Connect directly. iOS receives a specific home-screen guide while desktop and Android use their native install prompt.
Subscriptions belong to a user and device. Message previews are disabled by default so the lock screen does not become a plaintext channel.
The shell has a safe offline page. Messages and API responses are not indiscriminately cached; local history uses dedicated encryption.
Safe areas, standalone mode and push for installed PWAs.
Install prompt, push and app-shell integration.
Dedicated window and productive multi-column view.
Expose and deliberately activate new versions.
Show unread state on supported devices.
Clear failure boundaries instead of stale data.
“Installable does not mean that browser and security boundaries disappear.”
VENTEX PWA principle
Open, sign in and install it as a standalone app.
