Audited the renderer bundle with rollup-plugin-visualizer. Top offenders
(libsodium-sumo 292KB gz, livekit-client 177KB gz, @supabase 149KB gz)
all have justified usage and no viable swap. Mediapipe + track-processors
are already lazy-loaded into a separate chunk on first BackgroundBlur
activation. Bundle has zero duplicate packages, no moment/lodash/dayjs,
no syntax-highlight libs, no polyfills — already lean from T1+T6.
Added rollup-plugin-visualizer as a dev-dep, gated behind ANALYZE=true
so production builds pay no cost. Run with:
ANALYZE=true pnpm --filter @chat-app/desktop build
to regenerate stats.html (treemap) + stats.json (raw) for future audits.
Switches the ConversationPage chat list from a full O(N) render to
windowed rendering via react-virtuoso. On long histories only the
visible rows (plus a 400px overscan buffer) live in the DOM, ending the
scroll jank and layout thrashing that hit conversations with >500
messages.
Preserved behaviors:
- Newest message visible on open via initialTopMostItemIndex.
- Auto-scroll on send via a pending-count-based effect (the old
setStickToBottom + useLayoutEffect pattern doesn't apply now that
Virtuoso owns the scroll element).
- Realtime auto-follow only when scrolled to bottom (followOutput).
- 'New messages while away' counter + 'jump to newest' pill via
atBottomStateChange.
- Pinned-message / reply / search jumps via virtuosoRef.scrollToIndex;
expands displayCount on the fly if the target is outside the
rendered slice. Flash highlight unchanged.
- Load-older infinite scroll via Virtuoso startReached (replaces the
IntersectionObserver-on-sentinel pattern).
- Per-conversation position memory now keys on row index instead of
pixel scrollTop (the latter isn't meaningful under virtualization).
Also wires the PinnedMessagesPanel onJump callback (previously a TODO
that just closed the panel) into jumpToMessage, since virtualization
made the smooth-scroll-from-pinned UX easy to deliver as a side
benefit.
PackageList.java generated by RN autolinking imported expo.core.ExpoModulesPackage
(old SDK <48 name). Root cause: RN CLI couldn't read expo's react-native.config.js
through the pnpm symlink (it lives at .pnpm/expo@52..../expo/react-native.config.js),
so it fell back to deriving the import path from expo's Android gradle namespace
("expo.core") + assumed class name (ExpoModulesPackage), producing a path that
doesn't exist (the actual class lives at expo.modules.ExpoModulesPackage).
Added "expo" to .npmrc public-hoist-pattern so RN's autolinking can resolve
expo's react-native.config.js via the standard node_modules lookup. That config
explicitly sets packageImportPath to the correct expo.modules.ExpoModulesPackage.
Also corrected @expo/metro-runtime from 55.0.11 (added blindly earlier) to ~4.0.1
which is the SDK-52-aligned version.
pnpm's default strict isolation hides @babel/runtime/helpers/* and other
transitive deps from Metro, which expects flat node_modules layout.
Each missing dep was a separate failed EAS build (metro-runtime,
@babel/runtime, ...) — added .npmrc with public-hoist-pattern entries
that catch the common RN/Expo families so we stop whack-a-moling them.
Also kept @babel/runtime as direct dep of @chat-app/mobile for safety.
expo-router@4 imports @expo/metro-runtime as the very first thing in its
entry-classic.js so Fast Refresh works; bundler errored without it.
Also dropped expo-router/babel from babel.config.js — its functionality
moved into babel-preset-expo in SDK 50.
Phase 0 installed expo-application/expo-image-picker/expo-dev-client at
^55.x assuming the major version matched the SDK number. It doesn't —
each expo-* package has its own major. Misaligned versions pulled in
expo-modules-core@2.2.3 which expects an API that SDK 52's gradle plugin
host doesn't provide, breaking the Gradle build with
'expo-module-gradle-plugin not found'.
`expo install --fix` aligned everything to SDK 52 baselines:
expo-application 55.0.15 -> ~6.0.2
expo-dev-client 55.0.33 -> ~5.0.20
expo-image-picker 55.0.20 -> ~16.0.6
expo-sqlite 15.0.6 -> ~15.1.4
react-native 0.76.0 -> 0.76.9
+ RN companion libs (gesture-handler, screens, async-storage)
Messages:
- Reply-to: hover action, composer chip with cancel, quote bubble inside
the replying message with tap-to-jump + amber highlight ring
- Search: header search button toggles in-conversation search bar with
prev/next + match counter, auto-jump to active match
- Forward: multi-select conversation picker. Attachments are now carried
over: download + decrypt source, re-encrypt under each target conv-key,
re-upload with fresh per-attachment keys, insert new attachment rows
Conversations:
- Archive + mute per member. New migration 20260420000001 adds `archived`
+ `muted_until` on conversation_members. Shared helpers:
setConversationArchived / setConversationMutedUntil / isConversationMuted
- ChatsPage: archive toggle in header with unread badge for archived
bucket, split active/archived lists, muted indicator (BellOff icon,
dimmed unread badge)
- ConversationRowMenu via createPortal (escapes sidebar overflow clip),
forwardRef-based MenuItem so submenu positioning refs survive React 18
- ConversationsContext: suppresses notification sound + OS notif when
target conversation is muted
- Refresh on `profiles UPDATE` realtime so peer avatar / displayName
changes flow to conversation.members without manual refresh
Resilience:
- ErrorBoundary (Discord-style): centred spinner + escalating copy, no
manual reload button. Backoff retry schedule [2s, 4s, 8s, 15s, 30s].
Uses a keyed Fragment (not a div wrapper) so flex h-full chains survive
- App wrapped root + per-route RouteBoundary, conversation-level boundary
- AuthContext: flip `ready` immediately on cached session read; validate
getUser in background so a stalled/offline Supabase doesn't freeze the
app on the loading spinner
Crypto:
- Swap libsodium-wrappers -> libsodium-wrappers-sumo (compact build was
missing crypto_pwhash so Argon2id vault KDF threw, falling back to
plaintext localStorage on every launch)
- Shim d.ts for sumo types (sumo is API superset, no official types ship)
- vite optimizeDeps includes sumo with the "require" condition
- secureFileStore: exists(dir) check before mkdir; surface genuine
permission errors instead of silent catch
Tauri:
- fs scope adds `$APPLOCALDATA` direct entry (not just /**) so the app
data directory itself can be mkdir'd on first launch
Chat layout:
- Skip call_event messages when computing avatar run boundaries so a
regular bubble followed by a call event from the same sender still
shows its avatar
