refactor: standardize MobX store architecture with base classes and utilities
Refactored all stores to follow consistent patterns and best practices while keeping MobX: New Infrastructure: - Created base-store.ts with StandardState base class and factory functions - Added store-utils.ts with RequestDeduplicator, StoreError, and OptimisticUpdate helpers - Added config.ts for MobX configuration and strict mode - Created comprehensive README.md with architecture guide and examples Server State Stores (API data): - attachment.ts: Added request deduplication, error handling, computed properties, delete/clear methods - workspace.ts: Added Theme type validation, computed memoization, improved initialization - memo.ts: Enhanced with optimistic updates, request deduplication, structured errors - user.ts: Fixed temporal coupling, added computed memoization, request deduplication Client State Stores (UI state): - view.ts: Added helper methods (toggleSortOrder, setLayout, resetToDefaults), input validation - memoFilter.ts: Added utility methods (hasFilter, clearAllFilters, removeFiltersByFactor) Improvements: - Request deduplication prevents duplicate API calls (all server stores) - Computed property memoization improves performance - Structured error handling with error codes - Optimistic updates for better UX (memo updates) - Comprehensive JSDoc documentation - Type-safe APIs with proper exports - Clear separation between server and client state All stores now follow consistent patterns for better maintainability and easier onboarding. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>pull/5184/head

# Store Architecture
|
||||
|
||||
This directory contains the application's state management implementation using MobX.
|
||||
|
||||
## Overview
|
||||
|
||||
The store architecture follows a clear separation of concerns:
|
||||
|
||||
- **Server State Stores**: Manage data fetched from the backend API
|
||||
- **Client State Stores**: Manage UI preferences and transient state
|
||||
|
||||
## Store Files
|
||||
|
||||
### Server State Stores (API Data)
|
||||
|
||||
| Store | File | Purpose |
|
||||
|-------|------|---------|
|
||||
| `memoStore` | `memo.ts` | Memo CRUD operations, optimistic updates |
|
||||
| `userStore` | `user.ts` | User authentication, settings, stats |
|
||||
| `workspaceStore` | `workspace.ts` | Workspace profile and settings |
|
||||
| `attachmentStore` | `attachment.ts` | File attachment management |
|
||||
|
||||
**Features:**
|
||||
- ✅ Request deduplication (prevents duplicate API calls)
|
||||
- ✅ Structured error handling with `StoreError`
|
||||
- ✅ Computed property memoization for performance
|
||||
- ✅ Optimistic updates (immediate UI feedback)
|
||||
- ✅ Automatic caching
|
||||
|
||||
### Client State Stores (UI State)
|
||||
|
||||
| Store | File | Purpose | Persistence |
|
||||
|-------|------|---------|-------------|
|
||||
| `viewStore` | `view.ts` | Display preferences (sort, layout) | localStorage |
|
||||
| `memoFilterStore` | `memoFilter.ts` | Active search filters | URL params |
|
||||
|
||||
**Features:**
|
||||
- ✅ No API calls (instant updates)
|
||||
- ✅ localStorage persistence (viewStore)
|
||||
- ✅ URL synchronization (memoFilterStore - shareable links)
|
||||
|
||||
### Utilities
|
||||
|
||||
| File | Purpose |
|
||||
|------|---------|
|
||||
| `base-store.ts` | Base classes and factory functions |
|
||||
| `store-utils.ts` | Request deduplication, error handling, optimistic updates |
|
||||
| `config.ts` | MobX configuration |
|
||||
| `common.ts` | Shared constants and utilities |
|
||||
| `index.ts` | Centralized exports |
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Basic Store Usage
|
||||
|
||||
```typescript
|
||||
import { memoStore, userStore, viewStore } from "@/store";
|
||||
import { observer } from "mobx-react-lite";
|
||||
|
||||
const MyComponent = observer(() => {
|
||||
// Access state
|
||||
const memos = memoStore.state.memos;
|
||||
const currentUser = userStore.state.currentUser;
|
||||
const sortOrder = viewStore.state.orderByTimeAsc;
|
||||
|
||||
// Call actions
|
||||
const handleCreate = async () => {
|
||||
await memoStore.createMemo({ content: "Hello" });
|
||||
};
|
||||
|
||||
const toggleSort = () => {
|
||||
viewStore.toggleSortOrder();
|
||||
};
|
||||
|
||||
return <div>...</div>;
|
||||
});
|
||||
```
|
||||
|
||||
### Server Store Pattern
|
||||
|
||||
```typescript
|
||||
// Fetch data with automatic deduplication
|
||||
const memo = await memoStore.getOrFetchMemoByName("memos/123");
|
||||
|
||||
// Update with optimistic UI updates
|
||||
await memoStore.updateMemo({ name: "memos/123", content: "Updated" }, ["content"]);
|
||||
|
||||
// Errors are wrapped in StoreError
|
||||
try {
|
||||
await memoStore.deleteMemo("memos/123");
|
||||
} catch (error) {
|
||||
if (error instanceof StoreError) {
|
||||
console.error(error.code, error.message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Client Store Pattern
|
||||
|
||||
```typescript
|
||||
// View preferences (persisted to localStorage)
|
||||
viewStore.setLayout("MASONRY");
|
||||
viewStore.toggleSortOrder();
|
||||
|
||||
// Filters (synced to URL)
|
||||
memoFilterStore.addFilter({ factor: "tagSearch", value: "work" });
|
||||
memoFilterStore.removeFiltersByFactor("tagSearch");
|
||||
memoFilterStore.clearAllFilters();
|
||||
```
|
||||
|
||||
## Creating New Stores
|
||||
|
||||
### Server State Store
|
||||
|
||||
```typescript
|
||||
import { StandardState, createServerStore } from "./base-store";
|
||||
import { createRequestKey, StoreError } from "./store-utils";
|
||||
|
||||
class MyState extends StandardState {
|
||||
dataMap: Record<string, Data> = {};
|
||||
|
||||
get items() {
|
||||
return Object.values(this.dataMap);
|
||||
}
|
||||
}
|
||||
|
||||
const myStore = (() => {
|
||||
const base = createServerStore(new MyState(), {
|
||||
name: "myStore",
|
||||
enableDeduplication: true,
|
||||
});
|
||||
|
||||
const { state, executeRequest } = base;
|
||||
|
||||
const fetchItems = async () => {
|
||||
return executeRequest(
|
||||
createRequestKey("fetchItems"),
|
||||
async () => {
|
||||
const items = await api.fetchItems();
|
||||
state.setPartial({ dataMap: items });
|
||||
return items;
|
||||
},
|
||||
"FETCH_ITEMS_FAILED"
|
||||
);
|
||||
};
|
||||
|
||||
return { state, fetchItems };
|
||||
})();
|
||||
```
|
||||
|
||||
### Client State Store
|
||||
|
||||
```typescript
|
||||
import { StandardState } from "./base-store";
|
||||
|
||||
class MyState extends StandardState {
|
||||
preference: string = "default";
|
||||
|
||||
setPartial(partial: Partial<MyState>) {
|
||||
Object.assign(this, partial);
|
||||
// Optional: persist to localStorage
|
||||
localStorage.setItem("my-preference", JSON.stringify(this));
|
||||
}
|
||||
}
|
||||
|
||||
const myStore = (() => {
|
||||
const state = new MyState();
|
||||
|
||||
const setPreference = (value: string) => {
|
||||
state.setPartial({ preference: value });
|
||||
};
|
||||
|
||||
return { state, setPreference };
|
||||
})();
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### ✅ Do
|
||||
|
||||
- Use `observer()` HOC for components that access store state
|
||||
- Call store actions from event handlers
|
||||
- Use computed properties for derived state
|
||||
- Handle errors from async store operations
|
||||
- Keep stores focused on a single domain
|
||||
|
||||
### ❌ Don't
|
||||
|
||||
- Don't mutate store state directly - use `setPartial()` or action methods
|
||||
- Don't call async store methods during render
|
||||
- Don't mix server and client state in the same store
|
||||
- Don't access stores outside of React components (except initialization)
|
||||
|
||||
## Performance Tips
|
||||
|
||||
1. **Computed Properties**: Use getters for derived state - they're memoized by MobX
|
||||
2. **Request Deduplication**: Automatic for server stores - prevents wasted API calls
|
||||
3. **Optimistic Updates**: Used in `updateMemo` - immediate UI feedback
|
||||
4. **Fine-grained Reactivity**: MobX only re-renders components that access changed properties
|
||||
|
||||
## Testing
|
||||
|
||||
```typescript
|
||||
import { memoStore } from "@/store";
|
||||
|
||||
describe("memoStore", () => {
|
||||
it("should fetch memos", async () => {
|
||||
const memos = await memoStore.fetchMemos({ filter: "..." });
|
||||
expect(memos).toBeDefined();
|
||||
});
|
||||
|
||||
it("should cache memos", () => {
|
||||
const memo = memoStore.getMemoByName("memos/123");
|
||||
expect(memo).toBeDefined();
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Migration Guide
|
||||
|
||||
If you're migrating from old store patterns:
|
||||
|
||||
1. **Replace direct state mutations** with `setPartial()`:
|
||||
```typescript
|
||||
// Before
|
||||
store.state.value = 5;
|
||||
|
||||
// After
|
||||
store.state.setPartial({ value: 5 });
|
||||
```
|
||||
|
||||
2. **Wrap API calls** with `executeRequest()`:
|
||||
```typescript
|
||||
// Before
|
||||
const data = await api.fetch();
|
||||
state.data = data;
|
||||
|
||||
// After
|
||||
return executeRequest("fetchData", async () => {
|
||||
const data = await api.fetch();
|
||||
state.setPartial({ data });
|
||||
return data;
|
||||
}, "FETCH_FAILED");
|
||||
```
|
||||
|
||||
3. **Use StandardState** for new stores:
|
||||
```typescript
|
||||
// Before
|
||||
class State {
|
||||
constructor() { makeAutoObservable(this); }
|
||||
}
|
||||
|
||||
// After
|
||||
class State extends StandardState {
|
||||
// makeAutoObservable() called automatically
|
||||
}
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**Q: Component not re-rendering when state changes?**
|
||||
A: Make sure you wrapped it with `observer()` from `mobx-react-lite`.
|
||||
|
||||
**Q: Getting "Cannot modify state outside of actions" error?**
|
||||
A: Use `state.setPartial()` instead of direct mutations.
|
||||
|
||||
**Q: API calls firing multiple times?**
|
||||
A: Check that your store uses `createServerStore()` with deduplication enabled.
|
||||
|
||||
**Q: localStorage not persisting?**
|
||||
A: Ensure your client store overrides `setPartial()` to call `localStorage.setItem()`.

||||
* - **memoStore**: Memo CRUD operations
|
||||
* - **userStore**: User authentication and settings
|
||||
* - **workspaceStore**: Workspace configuration
|
||||
* - **attachmentStore**: File attachment management
|
||||
*
|
||||
* Features:
|
||||
* - Request deduplication
|
||||
* - Error handling with StoreError
|
||||
* - Optimistic updates (memo updates)
|
||||
* - Computed property memoization
|
||||
*
|
||||
* ### Client State Stores (UI State)
|
||||
* These stores manage UI preferences and transient state:
|
||||
* - **viewStore**: Display preferences (sort order, layout)
|
||||
* - **memoFilterStore**: Active search filters
|
||||
*
|
||||
* Features:
|
||||
* - localStorage persistence (viewStore)
|
||||
* - URL synchronization (memoFilterStore)
|
||||
* - No API calls
|
||||
*
|
||||
* ## Usage
|
||||
*
|
||||
* ```typescript
|
||||
* import { memoStore, userStore, viewStore } from "@/store";
|
||||
* import { observer } from "mobx-react-lite";
|
||||
*
|
||||
* const MyComponent = observer(() => {
|
||||
* const memos = memoStore.state.memos;
|
||||
* const user = userStore.state.currentUser;
|
||||
*
|
||||
* return <div>...</div>;
|
||||
* });
|
||||
* ```
