LobeHub Store Data Structures
This guide covers how to structure data in Zustand stores for optimal performance and user experience.
Core Principles
✅ DO
- Separate List and Detail - Use different structures for list pages and detail pages
- Use Map for Details - Cache multiple detail pages with
Record<string, Detail> - Use Array for Lists - Simple arrays for list display
- Types from @lobechat/types - Never use
@lobechat/databasetypes in stores - Distinguish List and Detail types - List types may have computed UI fields
❌ DON'T
- Don't use single detail object - Can't cache multiple pages
- Don't mix List and Detail types - They have different purposes
- Don't use database types - Use types from
@lobechat/types

drizzle
Drizzle ORM schema authoring and query style for LobeHub (postgres, strict mode). Use when editing anything under `src/database/schemas/`, defining `pgTable` columns/indexes/junction tables, spreading `...timestamps`, generating `createInsertSchema`/`$inferSelect`/`$inferInsert` types, writing `db.select().from(...).leftJoin(...)` queries, or deciding when to split a relational `with:` into two queries. Triggers on `pgTable`, `db.select`, `db.query`, `eq()`/`and()`/`inArray()`, `uniqueIndex`, `primaryKey`, `references({ onDelete })`, 'add a column', 'new table', 'foreign key', 'junction table', 'schema field'. For migration files specifically, see the `db-migrations` skill.
649typescript
TypeScript code style and type-safety guide for LobeHub. Read before writing or editing any `.ts` / `.tsx` / `.mts` — covers `interface` vs `type`, `Record<PropertyKey, unknown>` over `any`/`object`, `as const satisfies`, `@ts-expect-error` over `@ts-ignore`, `import type` (`separate-type-imports`), `async`/`await` + `Promise.all`, `for…of` over indexed `for`, and the no-silent-`.catch(() => fallback)` rule. Also use when reviewing type quality, deciding module augmentation (`declare module`) over `namespace`, or designing extensible types (e.g. `PipelineContext.metadata`). Triggers on any TypeScript file edit, 'fix the type', 'why is this `any`', 'should this be interface or type', 'eslint type-import', 'ts-expect-error'.
633react
LobeHub React/SPA component conventions: antd-style with `createStaticStyles` + `cssVar.*` (prefer zero-runtime over `createStyles` + `token`), `@lobehub/ui/base-ui` primitives before `@lobehub/ui` before antd, `Flexbox`/`Center` for layouts, react-router-dom navigation, and the `.desktop.tsx` sync rule. Use when writing or editing any `.tsx` under `src/**`, picking a styling helper, choosing a component (Select/Modal/Drawer/Button/Tooltip), wiring routes in `desktopRouter.config.tsx`/`.desktop.tsx`, or adding a `Link`/`useNavigate` call in the SPA. Triggers on `createStyles`/`createStaticStyles`, `cssVar`, `@lobehub/ui`, `antd-style`, `Flexbox`, `useNavigate`, `react-router-dom`, `Link`, 'new component', 'add a page', 'edit a layout', 'desktopRouter', 'componentMap.desktop'.
632zustand
LobeHub Zustand store conventions: public/internal/dispatch action layers, optimistic update pattern, slice composition via `flattenActions`, and class-based action migration. Use whenever working under `src/store/**`, adding a `createXxxSlice`, writing `internal_*` or `internal_dispatch*` actions, designing `messagesMap`/`topicsMap` reducers, refactoring a `StateCreator` object slice into a `XxxActionImpl` class, or debugging stale store reads. Triggers on `useChatStore`/`useUserStore`/`useGlobalStore`, `createStore`, `flattenActions`, `StoreSetter`, `internal_dispatch`, 'add an action', 'zustand selector', 'store slice', 'class action', 'optimistic update'.
617project-overview
Complete project architecture and structure guide. Use when exploring the codebase, understanding project organization, finding files, or needing comprehensive architectural context. Triggers on architecture questions, directory navigation, or project overview needs.
599i18n
LobeHub internationalization with react-i18next. Use when adding any user-facing string in `.tsx`/`.ts` files, creating or renaming a key under `src/locales/default/{namespace}.ts`, deciding the `{feature}.{context}.{action}` flat-key pattern, wiring a new namespace into `src/locales/default/index.ts`, or translating zh-CN/en-US JSON for dev preview. Triggers on `useTranslation`, `t('foo.bar')`, `i18next.t`, `{{variable}}` interpolation, hardcoded UI strings (zh or en) that should be extracted, 'add i18n', '加 i18n key', '翻译', 'locale key', 'namespace', 'pnpm i18n'.
