There is a proof‑of‑concept (POC) on the frontend Project page. This document describes the desired future state for handling optimistic updates in a simple, consistent way. +## Core Architecture -## Mental Model +### Shared Utilities Module +**Location**: `src/features/shared/optimistic.ts` -Think of optimistic updates as "assuming success" - update the UI immediately for instant feedback, then verify with the server. If something goes wrong, revert to the last known good state. - -## The Pattern +Provides type-safe utilities for managing optimistic state across all features: +- `createOptimisticId()` - Generates stable UUIDs using nanoid +- `createOptimisticEntity()` - Creates entities with `_optimistic` and `_localId` metadata +- `isOptimistic()` - Type guard for checking optimistic state +- `replaceOptimisticEntity()` - Replaces optimistic items by `_localId` (race-condition safe) +- `removeDuplicateEntities()` - Deduplicates after replacement +- `cleanOptimisticMetadata()` - Strips optimistic fields when needed +### TypeScript Interface ```typescript -// 1. Save current state (for rollback) — take an immutable snapshot -const previousState = structuredClone(currentState); - -// 2. Update UI immediately -setState(newState); - -// 3. Call API -try { - const serverState = await api.updateResource(newState); - // Success — use server as the source of truth - setState(serverState); -} catch (error) { - // 4.
