feat(client): Twitter-style social feed UI (Phase C of v2.0.0)
Ships the client side of the v2.0.0 feed feature. Folds client-app/
into the monorepo (was previously .gitignored as "tracked separately"
but no separate repo ever existed — for v2.0.0 the client is
first-class).
Feed screens
app/(app)/feed.tsx — Feed tab
- Three-way tab strip: Подписки / Для вас / В тренде backed by
/feed/timeline, /feed/foryou, /feed/trending respectively
- Default landing tab is "Для вас" — surfaces discovery without
requiring the user to follow anyone first
- FlatList with pull-to-refresh + viewability-driven view counter
bump (posts visible ≥ 60% for ≥ 1s trigger POST /feed/post/…/view)
- Floating blue compose button → /compose
- Per-post liked_by_me fetched in batches of 6 after list load
app/(app)/compose.tsx — post composer modal
- Fullscreen, Twitter-like header (✕ left, Опубликовать right)
- Auto-focused multiline TextInput, 4000 char cap
- Hashtag preview chips that auto-update as you type
- expo-image-picker + expo-image-manipulator pipeline: resize to
1080px max-dim, JPEG Q=50 (client-side first-pass compression
before the mandatory server-side scrub)
- Live fee estimate + balance guard with a confirmation modal
("Опубликовать пост? Цена: 0.00X T · Размер: N KB")
- Exif: false passed to ImagePicker as an extra privacy layer
app/(app)/feed/[id].tsx — post detail
- Full PostCard rendering + detailed info panel (views, likes,
size, fee, hosting relay, hashtags as tappable chips)
- Triggers bumpView on mount
- 410 (on-chain soft-delete) routes back to the feed
app/(app)/feed/tag/[tag].tsx — hashtag feed
app/(app)/profile/[address].tsx — rebuilt
- Twitter-ish profile: avatar, name, address short-form, post count
- Posts | Инфо tab strip
- Follow / Unfollow button for non-self profiles (optimistic UI)
- Edit button on self profile → settings
- Secondary actions (chat, copy address) when viewing a known contact
Supporting library
lib/feed.ts — HTTP wrappers + tx builders for every /feed/* endpoint:
- publishPost (POST /feed/publish, signed)
- publishAndCommit (publish → on-chain CREATE_POST)
- fetchPost / fetchStats / bumpView
- fetchAuthorPosts / fetchTimeline / fetchForYou / fetchTrending /
fetchHashtag
- buildCreatePostTx / buildDeletePostTx
- buildFollowTx / buildUnfollowTx
- buildLikePostTx / buildUnlikePostTx
- likePost / unlikePost / followUser / unfollowUser / deletePost
(high-level helpers that bundle build + submitTx)
- formatFee, formatRelativeTime, formatCount — Twitter-like display
helpers
components/feed/PostCard.tsx — core card component
- Memoised for performance (N-row re-render on every like elsewhere
would cost a lot otherwise)
- Optimistic like toggle with heart-bounce spring animation
- Hashtag highlighting in body text (tappable → hashtag feed)
- Long-press context menu (Delete, owner-only)
- Views / likes / share-link / reply icons in footer row
Navigation cleanup
- NavBar: removed the SOON pill on the Feed tab (it's shipped now)
- (app)/_layout: hide NavBar on /compose and /feed/* sub-routes
- AnimatedSlot: treat /feed/<id>, /feed/tag/<t>, /compose as
sub-routes so back-swipe-right closes them
Channel removal (client side)
- lib/types.ts: ContactKind stripped to 'direct' | 'group'; legacy
'channel' flag removed. `kind` field kept for backward compat with
existing AsyncStorage records.
- lib/devSeed.ts: dropped the 5 channel seed contacts.
- components/ChatTile.tsx: removed channel kindIcon branch.
Dependencies
- expo-image-manipulator added for client-side image compression.
- expo-file-system/legacy used for readAsStringAsync (SDK 54 moved
that API to the legacy sub-path; the new streaming API isn't yet
stable).
Type check
- npx tsc --noEmit — clean, 0 errors.
Next (not in this commit)
- Direct attachment-bytes endpoint on the server so post-detail can
actually render the image (currently shows placeholder with URL)
- Cross-relay body fetch via /api/relays + hosting_relay pubkey
- Mentions (@username) with notifications
- Full-text search

*
|

* Секции:
|

* 1. Профиль — avatar, @username, short-address, Copy row.
|

* 2. Username — регистрация в native:username_registry (если не куплено).
|
||||
* 3. Node — URL + contract ID + Save + Status.
|
||||
* 4. Account — Export key, Delete account.
|
||||
*
|
||||
* Весь Pressable'овый layout живёт на ВНЕШНЕМ View с static style —
|
||||
* Pressable handle-ит только background change (через вложенный View
|
||||
* в ({pressed}) callback'е), никаких layout props в callback-style.
|
||||
* Это лечит web-баг, где Pressable style-функция не применяет
|
||||
* percentage/padding layout надёжно.
