# Accessibility Improvement Plan
|
||||
|
||||
This document outlines the accessibility improvements planned for Grimoire to achieve WCAG 2.1 AA compliance.
|
||||
|
||||
## Current State Assessment
|
||||
|
||||
**Current Coverage**: ~16% of components have ARIA attributes
|
||||
|
||||
| Category | Status | Details |
|
||||
|----------|--------|---------|
|
||||
| Keyboard Navigation | ⚠️ Partial | Cmd+K works, limited elsewhere |
|
||||
| Screen Reader Support | ⚠️ Partial | Basic labels, missing live regions |
|
||||
| Focus Management | ✅ Good | Visible focus rings |
|
||||
| Color Contrast | ⚠️ Unchecked | No WCAG verification |
|
||||
| Loading States | ✅ Good | Skeletons with aria-busy |
|
||||
| Error Handling | ⚠️ Partial | Errors not announced |
|
||||
|
||||
---
|
||||
|
||||
## Phase 1: Foundation (Priority: High)
|
||||
|
||||
### 1.1 Keyboard Navigation Improvements
|
||||
|
||||
**Files to update**: `CommandLauncher.tsx`, `Home.tsx`, `TabBar.tsx`
|
||||
|
||||
```typescript
|
||||
// Add keyboard shortcuts help modal (Cmd+?)
|
||||
const KEYBOARD_SHORTCUTS = [
|
||||
{ keys: ['⌘', 'K'], description: 'Open command palette' },
|
||||
{ keys: ['⌘', '1-9'], description: 'Switch workspace' },
|
||||
{ keys: ['Escape'], description: 'Close dialog/modal' },
|
||||
{ keys: ['↑', '↓'], description: 'Navigate list items' },
|
||||
{ keys: ['Enter'], description: 'Select/confirm' },
|
||||
];
|
||||
```
|
||||
|
||||
**Tasks**:
|
||||
- [ ] Create `KeyboardShortcutsDialog` component
|
||||
- [ ] Add `Cmd+?` shortcut to show help
|
||||
- [ ] Add keyboard navigation to window tiles (focus, close, resize)
|
||||
- [ ] Implement roving tabindex for command list
|
||||
- [ ] Add skip links for main content areas
|
||||
|
||||
### 1.2 Focus Management
|
||||
|
||||
**Files to update**: `components/ui/dialog.tsx`, `GlobalAuthPrompt.tsx`
|
||||
|
||||
```typescript
|
||||
// Focus trap for modals
|
||||
import { FocusTrap } from '@radix-ui/react-focus-trap';
|
||||
|
||||
// Return focus after dialog close
|
||||
const previousFocusRef = useRef<HTMLElement | null>(null);
|
||||
|
||||
useEffect(() => {
|
||||
if (open) {
|
||||
previousFocusRef.current = document.activeElement as HTMLElement;
|
||||
} else {
|
||||
previousFocusRef.current?.focus();
|
||||
}
|
||||
}, [open]);
|
||||
```
|
||||
|
||||
**Tasks**:
|
||||
- [ ] Verify all dialogs trap focus properly
|
||||
- [ ] Return focus to trigger element on close
|
||||
- [ ] Add `autoFocus` to first interactive element in dialogs
|
||||
- [ ] Prevent focus from leaving modal while open
|
||||
|
||||
### 1.3 Screen Reader Announcements (Live Regions)
|
||||
|
||||
**Create new file**: `src/components/ui/Announcer.tsx`
|
||||
|
||||
```typescript
|
||||
import { createContext, useContext, useState, useCallback } from 'react';
|
||||
|
||||
interface AnnouncerContextValue {
|
||||
announce: (message: string, politeness?: 'polite' | 'assertive') => void;
|
||||
}
|
||||
|
||||
const AnnouncerContext = createContext<AnnouncerContextValue | null>(null);
|
||||
|
||||
export function AnnouncerProvider({ children }: { children: React.ReactNode }) {
|
||||
const [politeMessage, setPoliteMessage] = useState('');
|
||||
const [assertiveMessage, setAssertiveMessage] = useState('');
|
||||
|
||||
const announce = useCallback((message: string, politeness: 'polite' | 'assertive' = 'polite') => {
|
||||
if (politeness === 'assertive') {
|
||||
setAssertiveMessage(message);
|
||||
setTimeout(() => setAssertiveMessage(''), 1000);
|
||||
} else {
|
||||
setPoliteMessage(message);
|
||||
setTimeout(() => setPoliteMessage(''), 1000);
|
||||
}
|
||||
}, []);
|
||||
|
||||
return (
|
||||
<AnnouncerContext.Provider value={{ announce }}>
|
||||
{children}
|
||||
<div
|
||||
aria-live="polite"
|
||||
aria-atomic="true"
|
||||
className="sr-only"
|
||||
>
|
||||
{politeMessage}
|
||||
</div>
|
||||
<div
|
||||
aria-live="assertive"
|
||||
aria-atomic="true"
|
||||
className="sr-only"
|
||||
>
|
||||
{assertiveMessage}
|
||||
</div>
|
||||
</AnnouncerContext.Provider>
|
||||
);
|
||||
}
|
||||
|
||||
export function useAnnounce() {
|
||||
const context = useContext(AnnouncerContext);
|
||||
if (!context) throw new Error('useAnnounce must be used within AnnouncerProvider');
|
||||
return context.announce;
|
||||
}
|
||||
```
|
||||
|
||||
**Integration points**:
|
||||
- [ ] Wrap app in `AnnouncerProvider`
|
||||
- [ ] Announce when command executes: "Opening profile viewer"
|
||||
- [ ] Announce when window closes: "Window closed"
|
||||
- [ ] Announce loading complete: "Timeline loaded, 50 events"
|
||||
- [ ] Announce errors: "Error: Failed to load profile"
|
||||
|
||||
---
|
||||
|
||||
## Phase 2: Form Accessibility (Priority: High)
|
||||
|
||||
### 2.1 Form Error Association
|
||||
|
||||
**Pattern to implement across all forms**:
|
||||
|
||||
```typescript
|
||||
interface FormFieldProps {
|
||||
id: string;
|
||||
label: string;
|
||||
error?: string;
|
||||
description?: string;
|
||||
}
|
||||
|
||||
function FormField({ id, label, error, description, children }: FormFieldProps) {
|
||||
const errorId = `${id}-error`;
|
||||
const descriptionId = `${id}-description`;
|
||||
|
||||
return (
|
||||
<div>
|
||||
<Label htmlFor={id}>{label}</Label>
|
||||
{description && (
|
||||
<span id={descriptionId} className="text-sm text-muted-foreground">
|
||||
{description}
|
||||
</span>
|
||||
)}
|
||||
{React.cloneElement(children as React.ReactElement, {
|
||||
id,
|
||||
'aria-describedby': [
|
||||
description ? descriptionId : null,
|
||||
error ? errorId : null,
|
||||
].filter(Boolean).join(' ') || undefined,
|
||||
'aria-invalid': !!error,
|
||||
})}
|
||||
{error && (
|
||||
<span id={errorId} role="alert" className="text-sm text-destructive">
|
||||
{error}
|
||||
</span>
|
||||
)}
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**Files to update**:
|
||||
- [ ] `SpellDialog.tsx` - Spell creation form
|
||||
- [ ] `SettingsDialog.tsx` - Settings inputs
|
||||
- [ ] `WorkspaceSettings.tsx` - Workspace name input
|
||||
- [ ] `CommandLauncher.tsx` - Command input
|
||||
|
||||
### 2.2 Required Field Indicators
|
||||
|
||||
```typescript
|
||||
// Add to Label component
|
||||
function Label({ required, children, ...props }) {
|
||||
return (
|
||||
<label {...props}>
|
||||
{children}
|
||||
{required && <span aria-hidden="true" className="text-destructive ml-1">*</span>}
|
||||
{required && <span className="sr-only"> (required)</span>}
|
||||
</label>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Phase 3: Component ARIA Improvements (Priority: Medium)
|
||||
|
||||
### 3.1 Event Renderers
|
||||
|
||||
**Base pattern for all renderers**:
|
||||
|
||||
```typescript
|
||||
// BaseEventRenderer.tsx additions
|
||||
<article
|
||||
aria-label={`${kindName} by ${authorName}`}
|
||||
aria-describedby={`event-${event.id}-content`}
|
||||
>
|
||||
<header>
|
||||
<UserName pubkey={pubkey} aria-label={`Author: ${displayName}`} />
|
||||
<time dateTime={isoDate} aria-label={`Posted ${relativeTime}`}>
|
||||
{relativeTime}
|
||||
</time>
|
||||
</header>
|
||||
<div id={`event-${event.id}-content`}>
|
||||
{children}
|
||||
</div>
|
||||
</article>
|
||||
```
|
||||
|
||||
**Tasks**:
|
||||
- [ ] Add `article` landmark to event containers
|
||||
- [ ] Add proper `time` elements with dateTime
|
||||
- [ ] Add aria-labels to interactive elements
|
||||
- [ ] Ensure all buttons have labels (close, menu, copy, etc.)
|
||||
|
||||
### 3.2 Feed/Timeline Components
|
||||
|
||||
**Files to update**: `Feed.tsx`, `ReqViewer.tsx`
|
||||
|
||||
```typescript
|
||||
// Add feed landmarks
|
||||
<section aria-label="Event timeline" role="feed" aria-busy={loading}>
|
||||
<h2 className="sr-only">Timeline</h2>
|
||||
{events.map((event, index) => (
|
||||
<article
|
||||
key={event.id}
|
||||
aria-posinset={index + 1}
|
||||
aria-setsize={events.length}
|
||||
>
|
||||
<KindRenderer event={event} />
|
||||
</article>
|
||||
))}
|
||||
</section>
|
||||
```
|
||||
|
||||
**Tasks**:
|
||||
- [ ] Add `role="feed"` to timeline containers
|
||||
- [ ] Add `aria-posinset` and `aria-setsize` for virtual lists
|
||||
- [ ] Add `aria-busy` during loading
|
||||
- [ ] Announce when new events arrive
|
||||
|
||||
### 3.3 Collapsible/Accordion
|
||||
|
||||
**Files to update**: `ui/accordion.tsx`, `ui/collapsible.tsx`
|
||||
|
||||
```typescript
|
||||
// Ensure proper ARIA states
|
||||
<button
|
||||
aria-expanded={isOpen}
|
||||
aria-controls={contentId}
|
||||
>
|
||||
Toggle
|
||||
</button>
|
||||
<div
|
||||
id={contentId}
|
||||
aria-hidden={!isOpen}
|
||||
role="region"
|
||||
>
|
||||
{children}
|
||||
</div>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Phase 4: Color & Visual Accessibility (Priority: Medium)
|
||||
|
||||
### 4.1 Color Contrast Audit
|
||||
|
||||
**Tool**: Use `axe-core` for automated checking
|
||||
|
||||
```bash
|
||||
npm install -D @axe-core/react
|
||||
```
|
||||
|
||||
```typescript
|
||||
// Development-only accessibility audit
|
||||
if (process.env.NODE_ENV === 'development') {
|
||||
import('@axe-core/react').then(axe => {
|
||||
axe.default(React, ReactDOM, 1000);
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Known issues to check**:
|
||||
- [ ] Muted foreground text (`hsl(215 20.2% 70%)`)
|
||||
- [ ] Gradient text (`.text-grimoire-gradient`)
|
||||
- [ ] Disabled state opacity (50%)
|
||||
- [ ] Placeholder text color
|
||||
|
||||
### 4.2 High Contrast Mode
|
||||
|
||||
**Create theme option**:
|
||||
|
||||
```css
|
||||
/* Add to index.css */
|
||||
@media (prefers-contrast: more) {
|
||||
:root {
|
||||
--foreground: 0 0% 0%;
|
||||
--background: 0 0% 100%;
|
||||
--muted-foreground: 0 0% 30%;
|
||||
--border: 0 0% 0%;
|
||||
}
|
||||
.dark {
|
||||
--foreground: 0 0% 100%;
|
||||
--background: 0 0% 0%;
|
||||
--muted-foreground: 0 0% 80%;
|
||||
--border: 0 0% 100%;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Tasks**:
|
||||
- [ ] Add system preference detection
|
||||
- [ ] Create high-contrast theme variables
|
||||
- [ ] Test with Windows High Contrast Mode
|
||||
- [ ] Add manual toggle in settings
|
||||
|
||||
### 4.3 Reduced Motion
|
||||
|
||||
```css
|
||||
/* Already partially implemented, verify coverage */
|
||||
@media (prefers-reduced-motion: reduce) {
|
||||
*,
|
||||
*::before,
|
||||
*::after {
|
||||
animation-duration: 0.01ms !important;
|
||||
animation-iteration-count: 1 !important;
|
||||
transition-duration: 0.01ms !important;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Tasks**:
|
||||
- [ ] Audit all animations (Framer Motion, CSS transitions)
|
||||
- [ ] Ensure skeleton pulse respects preference
|
||||
- [ ] Verify window transitions can be disabled
|
||||
|
||||
---
|
||||
|
||||
## Phase 5: Testing & Documentation (Priority: High)
|
||||
|
||||
### 5.1 Automated Testing
|
||||
|
||||
**Add to CI pipeline**:
|
||||
|
||||
```yaml
|
||||
# .github/workflows/accessibility.yml
|
||||
name: Accessibility Checks
|
||||
on: [push, pull_request]
|
||||
jobs:
|
||||
a11y:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
- uses: actions/checkout@v4
|
||||
- uses: actions/setup-node@v4
|
||||
- run: npm ci
|
||||
- run: npm run build
|
||||
- name: Run axe-core
|
||||
run: npx @axe-core/cli http://localhost:4173
|
||||
```
|
||||
|
||||
### 5.2 Manual Testing Checklist
|
||||
|
||||
**Keyboard-only testing**:
|
||||
- [ ] Can navigate entire app without mouse
|
||||
- [ ] Focus order is logical
|
||||
- [ ] All interactive elements are reachable
|
||||
- [ ] Can dismiss dialogs with Escape
|
||||
- [ ] Can activate buttons with Enter/Space
|
||||
|
||||
**Screen reader testing** (with VoiceOver/NVDA):
|
||||
- [ ] Page structure is announced correctly
|
||||
- [ ] Links and buttons describe their purpose
|
||||
- [ ] Form fields have associated labels
|
||||
- [ ] Errors are announced when they occur
|
||||
- [ ] Loading states are announced
|
||||
|
||||
**Visual testing**:
|
||||
- [ ] Content readable at 200% zoom
|
||||
- [ ] No horizontal scrolling at 320px width (for non-tiling views)
|
||||
- [ ] Focus indicators visible
|
||||
- [ ] Color not sole means of conveying info
|
||||
|
||||
### 5.3 Accessibility Documentation
|
||||
|
||||
**Create `docs/ACCESSIBILITY.md`**:
|
||||
- Document keyboard shortcuts
|
||||
- List known limitations
|
||||
- Provide screen reader recommendations
|
||||
- Document testing procedures
|

# Grimoire Codebase Analysis & S-Tier Quality Plan
|
||||
|
||||
**Analysis Date**: December 2025
|
||||
**Codebase Size**: ~28,500 lines of TypeScript across 240 files
|
||||
**Stack**: React 19 + TypeScript 5.6 + Vite 6 + TailwindCSS + Jotai + Dexie + Applesauce
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Grimoire is a **well-architected Nostr protocol explorer** with a unique tiling window manager interface. The codebase demonstrates strong engineering fundamentals with thoughtful patterns, comprehensive testing of core logic, and modern React practices. However, several areas require attention to reach S-tier quality.
|
||||
|
||||
### Current Quality Assessment
|
||||
|
||||
| Category | Grade | Summary |
|
||||
|----------|-------|---------|
|
||||
| **Architecture** | A- | Clean separation, singleton patterns, reactive data flow |
|
||||
| **Code Quality** | B+ | Strong patterns with some duplication and inconsistencies |
|
||||
| **Performance** | B+ | Good optimizations, but gaps in memoization |
|
||||
| **Security** | A | Zero vulnerabilities, proper input validation |
|
||||
| **Testing** | B | Excellent parser coverage, gaps in components/hooks |
|
||||
| **Accessibility** | C+ | Foundation present, sparse coverage |
|
||||
| **UX** | B | Desktop-first, keyboard-driven, limited mobile support |
|
||||
| **Documentation** | B- | Good inline docs, missing API documentation |
|
||||
|

|
||||
|
||||
## Part 1: Architecture Analysis
|
||||
|
||||
### Strengths
|
||||
|
||||
#### 1. Tri-Partite State Management
|
||||
The separation of concerns across three state systems is excellent:
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────────────┐
|
||||
│ STATE ARCHITECTURE │
|
||||
├──────────────────────┬──────────────────┬──────────────────────┤
|
||||
│ UI State (Jotai) │ Nostr State │ Relay/DB State │
|
||||
│ ├─ Workspaces │ (EventStore) │ (RelayLiveness) │
|
||||
│ ├─ Windows │ ├─ Events │ ├─ Connection state │
|
||||
│ ├─ Layout tree │ ├─ Profiles │ ├─ Auth preferences │
|
||||
│ └─ Active account │ └─ Replaceables │ └─ Backoff tracking │
|
||||
│ │ │ │
|
||||
│ localStorage │ In-memory RxJS │ IndexedDB (Dexie) │
|
||||
└──────────────────────┴──────────────────┴──────────────────────┘
|
||||
```
|
||||
|
||||
#### 2. Pure Function State Mutations (`src/core/logic.ts`)
|
||||
All UI state mutations follow a pure function pattern:
|
||||
```typescript
|
||||
export const addWindow = (state: GrimoireState, payload: AddWindowPayload): GrimoireState => ({
|
||||
...state,
|
||||
windows: { ...state.windows, [window.id]: window },
|
||||
// ...immutable updates
|
||||
});
|
||||
```
|
||||
|
||||
**Benefits**: Easily testable, predictable, no side effects
|
||||
|
||||
#### 3. Singleton Pattern for Services
|
||||
Critical services use singletons preventing resource duplication:
|
||||
- `EventStore` - Single source of truth for Nostr events
|
||||
- `RelayPool` - Reuses WebSocket connections
|
||||
- `RelayLiveness` - Centralized health tracking
|
||||
- `RelayStateManager` - Global connection + auth state
|
||||
|
||||
#### 4. Reactive Data Flow
|
||||
Applesauce + RxJS provides elegant reactive patterns:
|
||||
```typescript
|
||||
// Events flow: Relay → EventStore → Observable → Hook → Component
|
||||
const events = useTimeline(filters, relays); // Auto-updates on new events
|
||||
```
|
||||
|
||||
#### 5. Command System Design
|
||||
Unix-style man pages with async parsers:
|
||||
```typescript
|
||||
manPages: {
|
||||
req: {
|
||||
synopsis: "req [options] [relay...]",
|
||||
argParser: async (args) => parseReqCommand(args),
|
||||
appId: "req"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Weaknesses
|
||||
|
||||
#### 1. Disconnected State Systems
|
||||
- UI state (Jotai) doesn't know about relay health
|
||||
- Manual sync points (`useAccountSync`, `useRelayState`) create coupling
|
||||
- No unified error aggregation across systems
|
||||
|
||||
#### 2. Race Conditions
|
||||
```typescript
|
||||
// useProfile.ts - async DB write can outlive component
|
||||
const sub = profileLoader(...).subscribe({
|
||||
next: async (event) => {
|
||||
await db.profiles.put(...); // Component may unmount during await
|
||||
if (mounted) setProfile(...);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
#### 3. Polling Instead of Events
|
||||
```typescript
|
||||
// RelayStateManager polls every 1 second
|
||||
this.pollingIntervalId = setInterval(() => {
|
||||
pool.relays.forEach(relay => {
|
||||
if (!this.subscriptions.has(relay.url)) {
|
||||
this.monitorRelay(relay);
|
||||
}
|
||||
});
|
||||
}, 1000);
|
||||
```
|
||||
|
||||
#### 4. No Memory Bounds on EventStore
|
||||
EventStore can grow unbounded with continuous streams. No LRU eviction or max size.
|
||||
|
||||

|
||||
|
||||
## Part 2: Code Quality Analysis
|
||||
|
||||
### Strengths
|
||||
|
||||
#### 1. Kind Renderer Registry Pattern
|
||||
Scalable dispatch without conditionals:
|
||||
```typescript
|
||||
const kindRenderers: Record<number, ComponentType> = {
|
||||
0: ProfileRenderer,
|
||||
1: NoteRenderer,
|
||||
// 40+ kinds...
|
||||
};
|
||||
|
||||
export function KindRenderer({ event }) {
|
||||
const Renderer = kindRenderers[event.kind] || DefaultKindRenderer;
|
||||
return <Renderer event={event} />;
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. Error Boundary Strategy
|
||||
Three-tier isolation prevents cascading failures:
|
||||
- **App-level**: Full recovery UI with reload options
|
||||
- **Window-level**: Close broken window, others continue
|
||||
- **Event-level**: Single event fails, feed continues
|
||||
|
||||
#### 3. Dependency Stabilization Pattern
|
||||
Prevents infinite render loops in hooks:
|
||||
```typescript
|
||||
const stableFilters = useMemo(() => filters, [JSON.stringify(filters)]);
|
||||
const stableRelays = useMemo(() => relays, [relays.join(",")]);
|
||||
```
|
||||
|
||||
### Weaknesses
|
||||
|
||||
#### 1. Code Duplication
|
||||
|
||||
**Replaceable Event Constants** (duplicated in 2 files):
|
||||
```typescript
|
||||
// Both BaseEventRenderer.tsx and KindRenderer.tsx define:
|
||||
const REPLACEABLE_START = 10000;
|
||||
const REPLACEABLE_END = 20000;
|
||||
const PARAMETERIZED_REPLACEABLE_START = 30000;
|
||||
```
|
||||
|
||||
**Replaceable Detection Logic** (repeated 3+ times):
|
||||
```typescript
|
||||
const isAddressable =
|
||||
(event.kind >= REPLACEABLE_START && event.kind < REPLACEABLE_END) ||
|
||||
(event.kind >= PARAMETERIZED_REPLACEABLE_START && ...);
|
||||
```
|
||||
|
||||
**Dependency Stabilization** (in 4+ hooks):
|
||||
```typescript
|
||||
// Identical pattern in useTimeline, useReqTimeline, useLiveTimeline, useOutboxRelays
|
||||
const stableFilters = useMemo(() => filters, [JSON.stringify(filters)]);
|
||||
```
|
||||
|
||||
#### 2. Inconsistent Memoization
|
||||
- Only 14/40+ kind renderers use `useMemo`
|
||||
- Event handlers rarely wrapped in `useCallback`
|
||||
- Creates unnecessary re-renders in virtualized lists
|
||||
|
||||
#### 3. Type Safety Gaps
|
||||
```typescript
|
||||
// Scattered `as any` casts
|
||||
(args as any) // CommandLauncher.tsx:81
|
||||
```
|
||||
|
||||
#### 4. Dead Code
|
||||
```typescript
|
||||
// BaseEventRenderer.tsx has large commented-out blocks
|
||||
// import { kinds } from "nostr-tools";
|
||||
// ... commented compact mode code
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Part 3: Performance Analysis
|
||||
|
||||
### Strengths
|
||||
|
||||
#### 1. Strategic Code Splitting
|
||||
```typescript
|
||||
// vite.config.ts
|
||||
manualChunks: {
|
||||
'react-vendor': ['react', 'react-dom'],
|
||||
'ui': ['@radix-ui/*', 'react-mosaic-component'],
|
||||
'nostr': ['applesauce-*', 'nostr-tools', 'rxjs', 'dexie'],
|
||||
'markdown': ['react-markdown', 'remark-gfm']
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. Virtual Scrolling
|
||||
- `react-virtuoso` for large event feeds
|
||||
- Handles 1000+ events efficiently
|
||||
|
||||
#### 3. Lazy Loading
|
||||
```typescript
|
||||
const ProfileViewer = lazy(() => import("./ProfileViewer"));
|
||||
// All viewers lazy-loaded with Suspense fallback
|
||||
```
|
||||
|
||||
#### 4. Network Efficiency
|
||||
- Connection pooling via RelayPool singleton
|
||||
- Relay liveness prevents dead relay connections
|
||||
- Aggregator fallback for event discovery
|
||||
|
||||
### Weaknesses
|
||||
|
||||
#### 1. JSON.stringify in Dependencies
|
||||
```typescript
|
||||
// O(n) serialization on every render
|
||||
useMemo(() => filters, [JSON.stringify(filters)]);
|
||||
```
|
||||
|
||||
#### 2. Missing useMemo in Renderers
|
||||
Expensive operations computed on every render:
|
||||
- `formatTimestamp()` called repeatedly
|
||||
- Event content parsing without memoization
|
||||
- Profile data extraction
|
||||
|
||||
#### 3. No Performance Monitoring
|
||||
- No web vitals tracking
|
||||
- No performance budgets in build
|
||||
- No Lighthouse CI integration
|
||||

## Part 4: Security Analysis
|
||||
|
||||
### Strengths (Zero Critical Issues)
|
||||
|
||||
| Check | Status | Details |
|
||||
|-------|--------|---------|
|
||||
| XSS Prevention | ✅ | No `dangerouslySetInnerHTML`, `skipHtml` enabled in markdown |
|
||||
| Input Validation | ✅ | Regex patterns on NIP-05, URL normalization, title sanitization |
|
||||
| Dependency Security | ✅ | `npm audit` returns 0 vulnerabilities |
|
||||
| Memory Safety | ✅ | Proper subscription cleanup in all hooks |
|
||||
| Cryptography | ✅ | Delegated to trusted libraries (nostr-tools, applesauce) |
|
||||
|
||||
### Minor Concerns
|
||||
|
||||
1. **localStorage Usage**: Account metadata stored in world-readable localStorage (by design - no private keys)
|
||||
2. **No CSP Header**: Consider adding Content-Security-Policy meta tag
|
||||

## Part 5: Testing Analysis
|
||||
|
||||
### Current Coverage
|
||||
|
||||
| Category | Files | Coverage | Quality |
|
||||
|----------|-------|----------|---------|
|
||||
| Parsers | 7 | Excellent | ~95% edge cases |
|
||||
| State Logic | 1 | Comprehensive | All mutations tested |
|
||||
| Utilities | 11 | Good | Core paths covered |
|
||||
| Services | 2 | Moderate | Selection logic tested |
|
||||
| Components | 0 | None | Manual testing only |
|
||||
| Hooks | 0 | None | No subscription tests |
|
||||
|
||||
### Test Files (18 total)
|
||||
```
|

... (13 more utility tests)
|
||||
```
|
||||
|
||||
### Gaps
|
||||
|
||||
1. **No component tests** - All React components tested manually
|
||||
2. **No hook tests** - Subscription cleanup not verified
|
||||
3. **No integration tests** - End-to-end flows untested
|
||||
4. **No error boundary tests** - Recovery paths untested
|

|
||||
|
||||
## Part 6: Accessibility Analysis
|
||||
|
||||
### Strengths
|
||||
|
||||
- **Keyboard Navigation**: Cmd+K palette, arrow keys, Enter/Escape
|
||||
- **ARIA Labels**: 25 files with `aria-*` attributes
|
||||
- **Focus Management**: Visible focus rings with proper styling
|
||||
- **Screen Reader Support**: `VisuallyHidden` component, `sr-only` classes
|
||||
- **Loading States**: Skeletons with `role="status"` and `aria-busy`
|
||||
|
||||
### Weaknesses (Grade: C+)
|
||||
|
||||
| Issue | Impact | Current State |
|
||||
|-------|--------|---------------|
|
||||
| Sparse ARIA coverage | High | Only 16% of components have ARIA |
|
||||
| No form validation feedback | Medium | Errors not associated with inputs |
|
||||
| No high contrast mode | Medium | Single theme only |
|
||||
| Limited mobile support | High | Tiling UI unsuitable for touch |
|
||||
| No live regions | Medium | Dynamic updates not announced |
|
||||
| Missing keyboard legend | Low | Advanced shortcuts hidden |
|
||||
|
||||
---
|
||||
|
||||
## Part 7: UX Analysis
|
||||
|
||||
### Strengths
|
||||
|
||||
1. **Power User Focus**: Unix-style commands, keyboard-driven
|
||||
2. **Error Recovery**: Clear error states with retry options
|
||||
3. **Skeleton Loading**: Context-appropriate loading placeholders
|
||||
4. **Dark Mode Default**: Respects modern preferences
|
||||
5. **Workspace System**: Virtual desktops with persistence
|
||||
|
||||
### Weaknesses
|
||||
|
||||
1. **Desktop Only**: Tiling window manager not suited for mobile
|
||||
2. **Learning Curve**: No onboarding or tutorials
|
||||
3. **Discovery**: Advanced features not discoverable
|
||||
4. **No Undo**: Destructive actions (close window) not undoable
|
||||

|
||||
|
||||
## Part 8: S-Tier Improvement Plan
|
||||
|
||||
### Phase 1: Critical Fixes (Week 1-2)
|
||||
|
||||
#### 1.1 Extract Shared Constants
|
||||
```typescript
|
||||
// NEW FILE: src/lib/nostr-constants.ts
|
||||
export const REPLACEABLE_START = 10000;
|
||||
export const REPLACEABLE_END = 20000;
|
||||
export const EPHEMERAL_START = 20000;
|
||||
export const EPHEMERAL_END = 30000;
|
||||
export const PARAMETERIZED_REPLACEABLE_START = 30000;
|
||||
export const PARAMETERIZED_REPLACEABLE_END = 40000;
|
||||
|
||||
export function isReplaceableKind(kind: number): boolean {
|
||||
return (kind >= REPLACEABLE_START && kind < REPLACEABLE_END) ||
|
||||
(kind >= PARAMETERIZED_REPLACEABLE_START && kind < PARAMETERIZED_REPLACEABLE_END);
|
||||
}
|
||||
```
|
||||
|
||||
#### 1.2 Create Dependency Stabilization Hook
|
||||
```typescript
|
||||
// NEW FILE: src/hooks/useStable.ts
|
||||
export function useStableValue<T>(value: T, serialize?: (v: T) => string): T {
|
||||
const serialized = serialize?.(value) ?? JSON.stringify(value);
|
||||
return useMemo(() => value, [serialized]);
|
||||
}
|
||||
|
||||
export function useStableArray<T>(arr: T[]): T[] {
|
||||
return useMemo(() => arr, [arr.join(",")]);
|
||||
}
|
||||
```
|
||||
|
||||
#### 1.3 Fix Race Conditions
|
||||
```typescript
|
||||
// useProfile.ts - use AbortController pattern
|
||||
useEffect(() => {
|
||||
const controller = new AbortController();
|
||||
|
||||
const sub = profileLoader(...).subscribe({
|
||||
next: async (event) => {
|
||||
if (controller.signal.aborted) return;
|
||||
await db.profiles.put(...);
|
||||
if (!controller.signal.aborted) setProfile(...);
|
||||
}
|
||||
});
|
||||
|
||||
return () => {
|
||||
controller.abort();
|
||||
sub.unsubscribe();
|
||||
};
|
||||
}, [pubkey]);
|
||||
```
|
||||
|
||||
#### 1.4 Replace Polling with Events
|
||||
```typescript
|
||||
// RelayStateManager - use pool events instead of setInterval
|
||||
pool.on('relay:add', (relay) => this.monitorRelay(relay));
|
||||
pool.on('relay:remove', (url) => this.unmonitorRelay(url));
|
||||
```
|
||||
|
||||
### Phase 2: Performance Optimization (Week 3-4)
|
||||
|
||||
#### 2.1 Add useMemo to Kind Renderers
|
||||
Audit all 40+ kind renderers and add memoization for:
|
||||
- Content parsing
|
||||
- Tag extraction
|
||||
- Formatting operations
|
||||
|
||||
#### 2.2 Memoize Event Handlers
|
||||
```typescript
|
||||
// Wrap handlers passed to memoized children
|
||||
const handleReplyClick = useCallback(() => {
|
||||
addWindow("open", { pointer: replyPointer });
|
||||
}, [replyPointer, addWindow]);
|
||||
```
|
||||
|
||||
#### 2.3 Add EventStore Memory Bounds
|
||||
```typescript
|
||||
// Configure max events with LRU eviction
|
||||
const eventStore = new EventStore({
|
||||
maxEvents: 10000,
|
||||
evictionPolicy: 'lru'
|
||||
});
|
||||
```
|
||||
|
||||
#### 2.4 Implement Performance Monitoring
|
||||
```bash
|
||||
npm install web-vitals
|
||||
```
|
||||
```typescript
|
||||
// src/lib/analytics.ts
|
||||
import { onCLS, onFID, onLCP } from 'web-vitals';
|
||||
|
||||
export function initPerformanceMonitoring() {
|
||||
onCLS(console.log);
|
||||
onFID(console.log);
|
||||
onLCP(console.log);
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 3: Testing Excellence (Week 5-6)
|
||||
|
||||
#### 3.1 Component Testing Setup
|
||||
```bash
|
||||
npm install -D @testing-library/react @testing-library/jest-dom
|
||||
```
|
||||
|
||||
#### 3.2 Add Hook Tests
|
||||
```typescript
|
||||
// src/hooks/useProfile.test.ts
|
||||
describe('useProfile', () => {
|
||||
it('should clean up subscription on unmount', async () => {
|
||||
const { unmount } = renderHook(() => useProfile('pubkey'));
|
||||
unmount();
|
||||
// Verify no memory leaks
|
||||
});
|
||||
|
||||
it('should handle race conditions', async () => {
|
||||
// Rapid mount/unmount should not cause errors
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
#### 3.3 Error Boundary Tests
|
||||
```typescript
|
||||
describe('EventErrorBoundary', () => {
|
||||
it('should catch render errors', () => {...});
|
||||
it('should reset on event change', () => {...});
|
||||
it('should show retry button', () => {...});
|
||||
});
|
||||
```
|
||||
|
||||
#### 3.4 Integration Tests
|
||||
```typescript
|
||||
// src/__tests__/integration/command-flow.test.tsx
|
||||
describe('Command Flow', () => {
|
||||
it('should parse command and open window', async () => {
|
||||
// Type "profile alice" → verify window opens
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Phase 4: Accessibility (Week 7-8)
|
||||
|
||||
#### 4.1 Audit Tool Integration
|
||||
```bash
|
||||
npm install -D @axe-core/react
|
||||
```
|
||||
```typescript
|
||||
// Development-only accessibility audit
|
||||
if (process.env.NODE_ENV === 'development') {
|
||||
import('@axe-core/react').then(axe => {
|
||||
axe.default(React, ReactDOM, 1000);
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
#### 4.2 Form Error Pattern
|
||||
```typescript
|
||||
// Create consistent error association
|
||||
<Input
|
||||
id="relay-url"
|
||||
aria-describedby={error ? "relay-url-error" : undefined}
|
||||
aria-invalid={!!error}
|
||||
/>
|
||||
{error && (
|
||||
<span id="relay-url-error" role="alert" className="text-destructive">
|
||||
{error}
|
||||
</span>
|
||||
)}
|
||||
```
|
||||
|
||||
#### 4.3 Live Regions
|
||||
```typescript
|
||||
// Announce dynamic updates
|
||||
<div aria-live="polite" aria-atomic="true" className="sr-only">
|
||||
{statusMessage}
|
||||
</div>
|
||||
```
|
||||
|
||||
#### 4.4 Keyboard Shortcut Help
|
||||
```typescript
|
||||
// Add discoverable shortcut modal (Cmd+?)
|
||||
const shortcuts = [
|
||||
{ keys: ['⌘', 'K'], description: 'Open command palette' },
|
||||
{ keys: ['⌘', '1-9'], description: 'Switch workspace' },
|
||||
// ...
|
||||
];
|
||||
```
|
||||
|
||||
### Phase 5: UX Enhancements (Week 9-10)
|
||||
|
||||
#### 5.1 Onboarding Flow
|
||||
```typescript
|
||||
// First-time user experience
|
||||
const GrimoireWelcome = () => (
|
||||
<Dialog open={isFirstVisit}>
|
||||
<DialogContent>
|
||||
<h2>Welcome to Grimoire</h2>
|
||||
<p>Press ⌘K to get started...</p>
|
||||
<InteractiveDemo />
|
||||
</DialogContent>
|
||||
</Dialog>
|
||||
);
|
||||
```
|
||||
|
||||
#### 5.2 Undo System
|
||||
```typescript
|
||||
// Track recent actions for undo
|
||||
const undoStack = atom<Action[]>([]);
|
||||
|
||||
export function addWindow(state, payload) {
|
||||
pushUndo({ type: 'ADD_WINDOW', windowId: window.id });
|
||||
return { ...state, ... };
|
||||
}
|
||||
|
||||
export function undo(state) {
|
||||
const action = popUndo();
|
||||
// Reverse the action
|
||||
}
|
||||
```
|
||||
|
||||
#### 5.3 Mobile Detection
|
||||
```typescript
|
||||
// Show appropriate message on mobile
|
||||
const isMobile = /iPhone|iPad|Android/i.test(navigator.userAgent);
|
||||
|
||||
if (isMobile) {
|
||||
return <MobileNotSupported />;
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 6: Documentation & Polish (Week 11-12)
|
||||
|
||||
#### 6.1 API Documentation
|
||||
```typescript
|
||||
/**
|
||||
* Parse a REQ command string into filter and relay configuration
|
||||
*
|
||||
* @param args - Tokenized command arguments
|
||||
* @returns ParsedReqCommand with filter, relays, and resolution metadata
|
||||
*
|
||||
* @example
|
||||
* parseReqCommand(["-k", "1", "-a", "npub1..."]);
|
||||
* // Returns: { filter: { kinds: [1], authors: ["hex..."] }, ... }
|
||||
*/
|
||||
export function parseReqCommand(args: string[]): ParsedReqCommand
|
||||
```
|
||||
|
||||
#### 6.2 Architecture Documentation
|
||||
Create `docs/ARCHITECTURE.md` with:
|
||||
- State management diagram
|
||||
- Data flow documentation
|
||||
- Service interaction patterns
|
||||
|
||||
#### 6.3 Remove Dead Code
|
||||
- Delete commented code blocks
|
||||
- Remove unused imports
|
||||
- Clean up TODO/FIXME comments
|
||||
|
||||
#### 6.4 Add CI/CD Quality Gates
|
||||
```yaml

## Conclusion
|
||||
|
||||
Grimoire is a **solid B+ codebase** with excellent architecture fundamentals and security posture. The path to S-tier requires:
|
||||
|
||||
1. **Immediate**: Fix race conditions, extract shared code
|
||||
2. **Short-term**: Add memoization, expand testing
|
||||
3. **Medium-term**: Accessibility audit, UX improvements
|
||||
4. **Long-term**: Documentation, CI/CD quality gates
|
||||
|
||||
The codebase is well-positioned for these improvements - the architecture is sound, patterns are consistent, and the team clearly values quality. With focused effort on the gaps identified, Grimoire can reach S-tier status.
