What does this change?

Reopening a cached prompt now displays its actual liked/saved state, counts, and ratings. Mounted cards use current props, and Profile uses its follower query data. Like, save, and follow mutations share pending values across views, reject duplicate clicks while the same relationship is pending, and restore server-backed values with error feedback when a write fails.

Successful mutations update and refetch the current viewer's existing detail, feed, profile, recommendation, liked, and saved caches. Failed writes also invalidate viewer caches so a canceled or stale cross-tab read is recovered. Updates touch only the affected relationship, so a failed like cannot roll back a successful save or another prompt. Unliked and unsaved items leave their membership lists.

The services now take the desired state directly through setLike, setSave, and setFollow. Active writes use duplicate-safe upserts against the existing unique indexes; inactive writes use idempotent deletes. This prevents a stale UI from flipping newer server state in the wrong direction.

Fixes #80.

Review updates

  • Rebased onto current main and retained its current ["prompts", limit, viewer] feed key.
  • Viewer-scoped cache matching reads the viewer ID from the final key element instead of a fixed feed position.
  • usePrompts and the mutation tests share the same feed-key factory.
  • The write path passes change.active to the service instead of reading and toggling server state.
  • Matching queries are invalidated after successful and failed writes; top-creators invalidation remains limited to successful follows.

How was it tested?

  • Added 19 tests across the shared mutation hook, UI state, and desired-state services. Coverage includes cached state, returned and thrown errors, retry, rapid duplicate clicks across consumers, viewer-key matching, unrelated rows and accounts, membership removal, duplicate-safe writes, concurrent like/save outcomes, failed-write invalidation, and empty follower caches.
  • npm test: 27 files, 157 tests passed.
  • npm run lint: passes with 25 existing warnings and no errors.
  • npm run typecheck: passes.
  • npm run build: passes.
  • git diff origin/main --check: passes.
  • Hosted db:schema:check passes on the current head. The local Windows command reports the unchanged generated schema as out of date; this PR has no differences from main in supabase/, the schema builder, or package scripts.

Backend services are controlled test fixtures; this is not a live Supabase end-to-end claim.

This is really solid work @sridharkalaibala , thank you. It covers everything in #80: derived state instead of copies, no setters in the query function, and the pending overlay instead of snapshot rollbacks is a nice call, since a failed like can't undo a successful save.

A few things before it can merge.

1. Rebase, and watch the query keys. main has moved a fair bit, and the feed key is now ["prompts", limit, user?.id ?? null] instead of the 6-element version this branch has. belongsToViewer checks key[5] for prompts, so after a straight rebase the feed caches would never match and likes/saves would stop updating feed cards. CI would stay green, because useSocialMutation.test.tsx builds the old key shape by hand. Every key involved already ends with the viewer id, so matching on the last element instead of fixed positions would survive future changes. Please also have the tests use the real key shape from usePrompts rather than a hand-built array. usePrompts.ts and PromptDetail.tsx will conflict. The usePrompts key change here isn't needed anymore, since main already includes the user id.

2. Make the write idempotent. The mutation knows the desired state (change.active), but toggleLike, toggleSave and toggleFollow read the server and flip whatever is there. If the UI is stale, for example liked from another tab and then tapped here within the 60s stale window, tapping "like" still deletes the real like, which is the harm #80 describes. Could the services take the desired state instead? Something like setLike(userId, promptId, active), which inserts and ignores duplicates when true, and deletes when false.

Once those are in I'll review again straight away. Please keep #127, #129 and #130 parked until this one lands, since they touch the same files.

📝 Walkthrough

Walkthrough

The change centralizes like, save, and follow mutations in useSocialMutation. Services now apply explicit states. Prompt and profile views derive state from query data and pending mutations, with cache updates, rollback, notifications, and tests.

Changes

Social state synchronization

Layer / File(s) Summary
Explicit social write contracts
src/services/supabase/{likes,saves,follows}.ts, src/services/supabase/social-toggles.test.ts
Like, save, and follow services now use explicit active states with delete or duplicate-safe upsert operations. Tests cover request arguments and error propagation.
Shared mutation and query-key orchestration
src/hooks/useSocialMutation.ts, src/hooks/useSocialMutation.test.tsx, src/hooks/queryKeys.ts, src/hooks/usePrompts.ts
useSocialMutation coordinates authenticated writes, pending state, cache updates, rollback, notifications, and invalidation. Prompt query keys use a shared factory.
Prompt and profile state integration
src/components/prompts/PromptCard.tsx, src/pages/PromptDetail.tsx, src/pages/Profile.tsx, src/pages/SocialState.test.tsx
Prompt and profile interactions use the shared mutation hook. Displayed state derives from query data or pending mutation data. Tests cover cache-backed state, rerenders, failures, rollback, and rating updates.

Merge Risk: ⚪ Minimal · up to f4f72

Failed social actions refresh affected state, and follow actions no longer display a guessed follower count while query data is unavailable. No actionable merge-blocking risk remains.

Addressed both review points in rebased commit f4f7287:

  • Rebased onto current main (85f1092) and resolved the usePrompts.ts / PromptDetail.tsx conflicts while preserving main's current feed key and detail behavior.
  • Viewer-scoped cache matching now checks the last key element. The feed test uses the same promptsQueryKey factory as usePrompts, so it covers the current ["prompts", limit, viewer] shape.
  • Replaced read-then-toggle services with desired-state setLike, setSave, and setFollow calls. Active writes use duplicate-safe upserts against the existing unique indexes; inactive writes use idempotent deletes. The mutation passes change.active through directly.
  • Updated service and UI tests to assert the requested state and duplicate-safe writes.
  • Failed writes now also invalidate the canceled viewer queries so stale cross-tab state is refetched; top-creators remains limited to successful follow writes.
  • Successful follows leave an empty follower-count cache untouched instead of writing a guessed count before the authoritative refetch.

Validation on the rebased branch:

  • npm run lint passes with 25 existing warnings and no errors
  • npm run typecheck passes
  • npm test passes: 27 files, 157 tests
  • npm run build passes
  • git diff origin/main --check passes

npm run db:schema:check currently reports that supabase/schema.sql is out of date. This PR has no differences from current main in supabase/, the schema builder, or package scripts, so I left that unrelated generated-schema state unchanged.

Thanks @sridharkalaibala, both points are handled well. Matching on the viewer id at the end of the key and the setLike / setSave / setFollow services are exactly what I was after, and the test now uses the real key shape. Approving this!

Once this lands, please rebase #127 on top of it. I left a note there about what's still needed.
