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.

# 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()`.

/**
* Store Module
*
* This module exports all application stores and their types.
*
* ## Store Architecture
*
* Stores are divided into two categories:
*
* ### Server State Stores (Data Fetching)
* These stores fetch and cache data from the backend API:
* - **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;
