Round 2's dedup fixes for connect()/openConversation left two gaps that
only showed up under closer scrutiny (and, for the first one, actual
live reproduction):
- closeConversation() awaited the shared in-flight subscribe promise
before calling leave(), but didn't check whether a NEWER
openConversation() had since claimed the same topic while it was
waiting -- under React 19 StrictMode's mount->cleanup->remount, the
stale cleanup's leave() would detach the subscription the surviving
mount had just established, silently killing live updates for
whatever conversation you'd just opened. Fixed with a per-topic
generation counter: closeConversation only actually leaves if no
newer open has since claimed the topic.
- prefetchPreview (chat-list preview subscribe) never joined the same
in-flight tracking as openConversation, so opening a conversation
while its own preview subscribe was still resolving could still send
two overlapping {sub} packets at the same topic.
- resetTinode() didn't clear connectPromise/restorePromise or
disconnect a connection that was still mid-handshake (only guarded on
isConnected()) -- switching tenants while the old connection was slow
to respond could leave a new login silently waiting on the abandoned
old connection's outcome.
- subscribeMeTopic() got the same in-flight dedup as the others, for
consistency (no concrete concurrent caller today, cheap insurance
against a future one).
Also:
- getBlocks()'s response type was a flat Friend shape; the real
contract (confirmed against both the protocol doc's JSON example and
the old app's own consumer) nests the user under `.user`, so "already
blocked" state in DetailColumn was silently always false.
- useBootstrap() had no tenant in its query key and staleTime:Infinity,
so switching tenants without a full reload kept serving the PREVIOUS
tenant's message_policy/features/permissions/security forever.

Tinode Web
Briefing
Single-page web chat application for Tinode. The app is built on React. The Tinode javascript SDK has no external dependencies. Overall, it's a lot like open source WhatsApp or Telegram web apps.
Although the app is generally usable, keep in mind that this is work in progress. Some bugs probably exist, some features are missing. The app was tested in the latest Chrome & Firefox only. NPM package is available.
Try possibly newer or older version live at https://sandbox.tinode.co/.
For demo access and other instructions see here.
