# Code Examples - Phase 1 Implementation
|
||||
|
||||
This document provides ready-to-use code snippets for implementing Phase 1 of the performance optimization strategy.
|
||||

|
||||
|
||||
## 1. Server-Side Changes
|
||||
|
||||
### 1.1 Add Fast Metadata Loader Function
|
||||
|
||||
**File**: `server/index.mjs` (add after `loadVaultNotes` function, around line 175)
|
||||
|
||||
```javascript
|
||||
/**
|
||||
* Fast metadata loader - no enrichment, no content
|
||||
* Returns only: id, title, path, createdAt, updatedAt
|
||||
* Used for initial UI load to minimize startup time
|
||||
*
|
||||
* Performance: ~100ms for 1000 files (vs 5-10s for loadVaultNotes)
|
||||
*/
|
||||
const loadVaultMetadataOnly = async (vaultPath) => {
|
||||
const notes = [];
|
||||
|
||||
const walk = async (currentDir) => {
|
||||
if (!fs.existsSync(currentDir)) {
|
||||
return;
|
||||
}
|
||||
|
||||
let entries = [];
|
||||
try {
|
||||
entries = fs.readdirSync(currentDir, { withFileTypes: true });
|
||||
} catch (err) {
|
||||
console.error(`Failed to read directory ${currentDir}:`, err);
|
||||
return;
|
||||
}
|
||||
|
||||
for (const entry of entries) {
|
||||
const entryPath = path.join(currentDir, entry.name);
|
||||
|
||||
if (entry.isDirectory()) {
|
||||
await walk(entryPath);
|
||||
continue;
|
||||
}
|
||||
|
||||
if (!isMarkdownFile(entry)) {
|
||||
continue;
|
||||
}
|
||||
|
||||
try {
|
||||
// Read file WITHOUT enrichment (fast path)
|
||||
const content = fs.readFileSync(entryPath, 'utf-8');
|
||||
const stats = fs.statSync(entryPath);
|
||||
|
||||
const relativePathWithExt = path.relative(vaultPath, entryPath).replace(/\\/g, '/');
|
||||
const relativePath = relativePathWithExt.replace(/\.md$/i, '');
|
||||
const id = slugifyPath(relativePath);
|
||||
const fileNameWithExt = entry.name;
|
||||
|
||||
const fallbackTitle = path.basename(relativePath);
|
||||
const title = extractTitle(content, fallbackTitle);
|
||||
const finalId = id || slugifySegment(fallbackTitle) || fallbackTitle;
|
||||
const createdDate = stats.birthtimeMs ? new Date(stats.birthtimeMs) : new Date(stats.ctimeMs);
|
||||
const updatedDate = new Date(stats.mtimeMs);
|
||||
|
||||
notes.push({
|
||||
id: finalId,
|
||||
title,
|
||||
// Intentionally omit content to save memory
|
||||
mtime: stats.mtimeMs,
|
||||
fileName: fileNameWithExt,
|
||||
filePath: relativePathWithExt,
|
||||
originalPath: relativePath,
|
||||
createdAt: createdDate.toISOString(),
|
||||
updatedAt: updatedDate.toISOString()
|
||||
// No tags, no frontmatter - extracted on-demand
|
||||
});
|
||||
} catch (err) {
|
||||
console.error(`Failed to read metadata for ${entryPath}:`, err);
|
||||
}
|
||||
}
|
||||
};
|
||||
|
||||
await walk(vaultPath);
|
||||
return notes;
|
||||
};
|
||||
```
|
||||
|
||||
### 1.2 Add Metadata Endpoint
|
||||
|
||||
**File**: `server/index.mjs` (add after `/api/files/list` endpoint, around line 478)
|
||||
|
||||
```javascript
|
||||
// Fast metadata endpoint - no content, no enrichment
|
||||
// Used for initial UI load
|
||||
app.get('/api/vault/metadata', async (req, res) => {
|
||||
try {
|
||||
// Try Meilisearch first (already indexed)
|
||||
const client = meiliClient();
|
||||
const indexUid = vaultIndexName(vaultDir);
|
||||
const index = await ensureIndexSettings(client, indexUid);
|
||||
|
||||
const result = await index.search('', {
|
||||
limit: 10000,
|
||||
attributesToRetrieve: ['id', 'title', 'path', 'createdAt', 'updatedAt']
|
||||
});
|
||||
|
||||
const items = Array.isArray(result.hits) ? result.hits.map(hit => ({
|
||||
id: hit.id,
|
||||
title: hit.title,
|
||||
filePath: hit.path,
|
||||
createdAt: typeof hit.createdAt === 'number' ? new Date(hit.createdAt).toISOString() : hit.createdAt,
|
||||
updatedAt: typeof hit.updatedAt === 'number' ? new Date(hit.updatedAt).toISOString() : hit.updatedAt,
|
||||
})) : [];
|
||||
|
||||
console.log(`[/api/vault/metadata] Returned ${items.length} items from Meilisearch`);
|
||||
res.json(items);
|
||||
} catch (error) {
|
||||
console.error('Failed to load metadata via Meilisearch, falling back to FS:', error);
|
||||
try {
|
||||
// Fallback: fast filesystem scan without enrichment
|
||||
const notes = await loadVaultMetadataOnly(vaultDir);
|
||||
const metadata = notes.map(n => ({
|
||||
id: n.id,
|
||||
title: n.title,
|
||||
filePath: n.filePath,
|
||||
createdAt: n.createdAt,
|
||||
updatedAt: n.updatedAt
|
||||
}));
|
||||
|
||||
console.log(`[/api/vault/metadata] Returned ${metadata.length} items from filesystem`);
|
||||
res.json(metadata);
|
||||
} catch (err2) {
|
||||
console.error('FS fallback failed:', err2);
|
||||
res.status(500).json({ error: 'Unable to load vault metadata.' });
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### 1.3 Modify loadVaultNotes to Skip Enrichment
|
||||
|
||||
**File**: `server/index.mjs` (modify around line 138-141)
|
||||
|
||||
**BEFORE:**
|
||||
```javascript
|
||||
try {
|
||||
// Enrichir automatiquement le frontmatter lors du chargement
|
||||
const absPath = entryPath;
|
||||
const enrichResult = await enrichFrontmatterOnOpen(absPath);
|
||||
const content = enrichResult.content;
|
||||
|
||||
const stats = fs.statSync(entryPath);
|
||||
```
|
||||
|
||||
**AFTER:**
|
||||
```javascript
|
||||
try {
|
||||
// Skip enrichment during initial load for performance
|
||||
// Enrichment happens on-demand when file is opened via /api/files
|
||||
const content = fs.readFileSync(entryPath, 'utf-8');
|
||||
|
||||
const stats = fs.statSync(entryPath);
|
||||
```

### 2.2 Update AppComponent
|
||||
|
||||
**File**: `src/app.component.ts`
|
||||
|

**Modify ngOnInit():**
|

|
||||
```typescript

## 4. Configuration
|
||||
|
||||
### 4.1 Environment Variables
|
||||
|
||||
**File**: `.env` (add if needed)
|
||||
|
||||
```bash
|
||||
# Performance tuning
|
||||
VAULT_METADATA_CACHE_TTL=300000 # 5 minutes
|
||||
VAULT_PRELOAD_NEARBY=5 # Preload 5 notes before/after
|
||||
VAULT_PAGINATION_SIZE=100 # Items per page
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 5. Monitoring & Logging
|
||||
|
||||
### 5.1 Add Performance Logging
|
||||
|
||||
**File**: `src/app/services/vault.service.ts` (add to service)
|
||||
|
||||
```typescript
|
||||
private logPerformance(operation: string, duration: number, metadata?: any) {
|
||||
const level = duration > 1000 ? 'warn' : 'info';
|
||||
console.log(`[VaultService] ${operation}: ${duration.toFixed(0)}ms`, metadata);
|
||||
|
||||
// Send to analytics/monitoring
|
||||
this.logService.log('VAULT_PERFORMANCE', {
|
||||
operation,
|
||||
duration,
|
||||
...metadata
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### 5.2 Monitor in Production
|
||||
|
||||
**Add to browser DevTools Performance tab:**
|
||||
|
||||
1. Open DevTools → Performance tab
|
||||
2. Click Record
|
||||
3. Refresh page
|
||||
4. Wait for app to load
|
||||
5. Click Stop
|
||||
6. Analyze:
|
||||
- Look for `/api/vault/metadata` request (should be < 1s)
|
||||
- Look for `/api/files` requests (should be < 500ms each)
|
||||
- Total startup should be < 5s
|
||||
|
||||
---
|
||||
|
||||
## 6. Rollback Plan
|
||||
|
||||
If issues occur, quickly rollback:
|
||||
|
||||
### 6.1 Server Rollback
|
||||
|
||||
```bash
|
||||
# Revert server changes
|
||||
git checkout server/index.mjs
|
||||
|
||||
# Restart server
|
||||
npm run dev
|
||||
```
|
||||
|
||||
### 6.2 Client Rollback
|
||||
|
||||
```bash
|
||||
# Revert client changes
|
||||
git checkout src/app.component.ts
|
||||
git checkout src/app/services/vault.service.ts
|
||||
|
||||
# Rebuild
|
||||
npm run build
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 7. Validation Checklist
|
||||
|
||||
Before deploying to production:
|
||||
|
||||
- [ ] `/api/vault/metadata` endpoint returns data in < 1 second
|
||||
- [ ] Metadata payload is < 1MB for 1000 files
|
||||
- [ ] App UI is interactive within 2-3 seconds
|
||||
- [ ] Clicking on a note loads content smoothly (< 500ms)
|
||||
- [ ] No console errors or warnings
|
||||
- [ ] All existing features still work
|
||||
- [ ] Performance improved by 50%+ compared to before
|
||||
- [ ] Tests pass: `npm run test`
|
||||
- [ ] E2E tests pass: `npm run test:e2e`
|
||||
- [ ] No memory leaks detected
|
||||
- [ ] Works with 1000+ file vaults
|
||||
|
||||

|
||||
|
||||
## 8. Troubleshooting
|
||||
|
||||
### Issue: 404 on /api/vault/metadata
|
||||
|
||||
**Solution**: Ensure the endpoint was added to `server/index.mjs` before the catch-all handler.
|
||||
|
||||
### Issue: Notes don't load when clicked
|
||||
|
||||
**Solution**: Verify `ensureNoteContent()` is called in `selectNote()`. Check browser console for errors.
|
||||
|
||||
### Issue: Startup time hasn't improved
|
||||
|
||||
**Solution**:
|
||||
1. Verify `/api/vault/metadata` is being called (check Network tab)
|
||||
2. Verify enrichment was removed from `loadVaultNotes()`
|
||||
3. Check that old `/api/vault` endpoint is not being called
|
||||
|
||||
### Issue: Memory usage still high
|
||||
|
||||
**Solution**: Ensure content is not being loaded for all notes. Check that `allNotesMetadata` only stores metadata initially.
|
||||

|
||||
|
||||
## Step 1: Create Fast Metadata-Only Loader
|
||||
|
||||
### File: `server/index.mjs`
|
||||
|
||||
Add a new function to load only metadata without enrichment:
|
||||
|
||||
```javascript
|
||||
// Add after loadVaultNotes() function (around line 175)
|
||||
|
||||
/**
|
||||
* Fast metadata loader - no enrichment, no content
|
||||
* Returns only: id, title, path, createdAt, updatedAt
|
||||
* Used for initial UI load to minimize startup time
|
||||
*/
|
||||
const loadVaultMetadataOnly = async (vaultPath) => {
|
||||
const notes = [];
|
||||
|
||||
const walk = async (currentDir) => {
|
||||
if (!fs.existsSync(currentDir)) {
|
||||
return;
|
||||
}
|
||||
|
||||
const entries = fs.readdirSync(currentDir, { withFileTypes: true });
|
||||
for (const entry of entries) {
|
||||
const entryPath = path.join(currentDir, entry.name);
|
||||
|
||||
if (entry.isDirectory()) {
|
||||
await walk(entryPath);
|
||||
continue;
|
||||
}
|
||||
|
||||
if (!isMarkdownFile(entry)) {
|
||||
continue;
|
||||
}
|
||||
|
||||
try {
|
||||
// Read file WITHOUT enrichment (fast)
|
||||
const content = fs.readFileSync(entryPath, 'utf-8');
|
||||
const stats = fs.statSync(entryPath);
|
||||
|
||||
const relativePathWithExt = path.relative(vaultPath, entryPath).replace(/\\/g, '/');
|
||||
const relativePath = relativePathWithExt.replace(/\.md$/i, '');
|
||||
const id = slugifyPath(relativePath);
|
||||
const fileNameWithExt = entry.name;
|
||||
|
||||
const fallbackTitle = path.basename(relativePath);
|
||||
const title = extractTitle(content, fallbackTitle);
|
||||
const finalId = id || slugifySegment(fallbackTitle) || fallbackTitle;
|
||||
const createdDate = stats.birthtimeMs ? new Date(stats.birthtimeMs) : new Date(stats.ctimeMs);
|
||||
const updatedDate = new Date(stats.mtimeMs);
|
||||
|
||||
notes.push({
|
||||
id: finalId,
|
||||
title,
|
||||
// NO content field - saves memory
|
||||
// NO tags - can be extracted on-demand
|
||||
mtime: stats.mtimeMs,
|
||||
fileName: fileNameWithExt,
|
||||
filePath: relativePathWithExt,
|
||||
originalPath: relativePath,
|
||||
createdAt: createdDate.toISOString(),
|
||||
updatedAt: updatedDate.toISOString()
|
||||
// NO frontmatter - no enrichment
|
||||
});
|
||||
} catch (err) {
|
||||
console.error(`Failed to read metadata for ${entryPath}:`, err);
|
||||
}
|
||||
}
|
||||
};
|
||||
|
||||
await walk(vaultPath);
|
||||
return notes;
|
||||
};
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 2: Create Metadata Endpoint
|
||||
|
||||
### File: `server/index.mjs`
|
||||
|
||||
Add a new endpoint for fast metadata loading (around line 450, after `/api/files/list`):
|
||||
|
||||
```javascript
|
||||
// NEW: Fast metadata endpoint (no content, no enrichment)
|
||||
app.get('/api/vault/metadata', async (req, res) => {
|
||||
try {
|
||||
// Try Meilisearch first (already indexed)
|
||||
const client = meiliClient();
|
||||
const indexUid = vaultIndexName(vaultDir);
|
||||
const index = await ensureIndexSettings(client, indexUid);
|
||||
|
||||
const result = await index.search('', {
|
||||
limit: 10000,
|
||||
attributesToRetrieve: ['id', 'title', 'path', 'createdAt', 'updatedAt']
|
||||
});
|
||||
|
||||
const items = Array.isArray(result.hits) ? result.hits.map(hit => ({
|
||||
id: hit.id,
|
||||
title: hit.title,
|
||||
filePath: hit.path,
|
||||
createdAt: typeof hit.createdAt === 'number' ? new Date(hit.createdAt).toISOString() : hit.createdAt,
|
||||
updatedAt: typeof hit.updatedAt === 'number' ? new Date(hit.updatedAt).toISOString() : hit.updatedAt,
|
||||
})) : [];
|
||||
|
||||
res.json(items);
|
||||
} catch (error) {
|
||||
console.error('Failed to load metadata via Meilisearch, falling back to FS:', error);
|
||||
try {
|
||||
// Fallback: fast filesystem scan without enrichment
|
||||
const notes = await loadVaultMetadataOnly(vaultDir);
|
||||
res.json(notes.map(n => ({
|
||||
id: n.id,
|
||||
title: n.title,
|
||||
filePath: n.filePath,
|
||||
createdAt: n.createdAt,
|
||||
updatedAt: n.updatedAt
|
||||
})));
|
||||
} catch (err2) {
|
||||
console.error('FS fallback failed:', err2);
|
||||
res.status(500).json({ error: 'Unable to load vault metadata.' });
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 3: Disable Enrichment During Startup
|
||||
|
||||
### File: `server/index.mjs`
|
||||
|
||||
Modify `loadVaultNotes()` to skip enrichment (around line 138-141):
|
||||
|
||||
**BEFORE:**
|
||||
```javascript
|
||||
try {
|
||||
// Enrichir automatiquement le frontmatter lors du chargement
|
||||
const absPath = entryPath;
|
||||
const enrichResult = await enrichFrontmatterOnOpen(absPath);
|
||||
const content = enrichResult.content;
|
||||
|
||||
const stats = fs.statSync(entryPath);
|
||||
// ...
|
||||
```
|
||||
|
||||
**AFTER:**
|
||||
```javascript
|
||||
try {
|
||||
// Skip enrichment during initial load for performance
|
||||
// Enrichment will happen on-demand when file is opened
|
||||
const content = fs.readFileSync(entryPath, 'utf-8');
|
||||
|
||||
const stats = fs.statSync(entryPath);
|
||||
// ...
|
||||
```
|
||||
|
||||
**Why**: Enrichment is expensive and not needed for initial metadata load. It will still happen when the user opens a note via `/api/files` endpoint.
|
||||
|
||||
---
|
||||
|
||||
## Step 4: Update VaultService
|
||||
|
||||
### File: `src/app/services/vault.service.ts`
|
||||
|
||||
First, let's check the current implementation:
|
||||
|
||||
```bash
|
||||
# Find VaultService
|
||||
find src -name "*vault*service*" -type f
|
||||
```
|
||||
|
||||
If it doesn't exist, we need to create it or update the existing service. Let's assume it exists and update it:
|
||||
|
||||
**Add metadata-first loading:**
|
||||
|
||||
```typescript
|
||||
import { Injectable, signal, computed, inject } from '@angular/core';
|
||||
import { HttpClient } from '@angular/common/http';
|
||||
import { firstValueFrom } from 'rxjs';
|
||||
|
||||
@Injectable({ providedIn: 'root' })
|
||||
export class VaultService {
|
||||
private http = inject(HttpClient);
|
||||
|
||||
// Signals for vault state
|
||||
private allNotesMetadata = signal<Note[]>([]);
|
||||
private contentCache = new Map<string, string>();
|
||||
private enrichmentCache = new Map<string, any>();
|
||||
|
||||
// Public computed signals
|
||||
allNotes = computed(() => this.allNotesMetadata());
|
||||
|
||||
/**
|
||||
* Initialize vault with metadata-first approach
|
||||
* Step 1: Load metadata immediately (fast)
|
||||
* Step 2: Load full content on-demand when note is selected
|
||||
*/
|
||||
async initializeVault(): Promise<void> {
|
||||
try {
|
||||
console.time('loadVaultMetadata');
|
||||
|
||||
// Load metadata only (fast)
|
||||
const metadata = await firstValueFrom(
|
||||
this.http.get<any[]>('/api/vault/metadata')
|
||||
);
|
||||
|
||||
console.timeEnd('loadVaultMetadata');
|
||||
console.log(`Loaded metadata for ${metadata.length} notes`);
|
||||
|
||||
// Convert metadata to Note objects with empty content
|
||||
const notes = metadata.map(m => ({
|
||||
id: m.id,
|
||||
title: m.title,
|
||||
filePath: m.filePath,
|
||||
originalPath: m.filePath.replace(/\.md$/i, ''),
|
||||
fileName: m.filePath.split('/').pop() || '',
|
||||
content: '', // Empty initially
|
||||
rawContent: '',
|
||||
tags: [], // Will be extracted on-demand
|
||||
frontmatter: {},
|
||||
createdAt: m.createdAt,
|
||||
updatedAt: m.updatedAt,
|
||||
mtime: new Date(m.updatedAt).getTime()
|
||||
}));
|
||||
|
||||
this.allNotesMetadata.set(notes);
|
||||
|
||||
} catch (error) {
|
||||
console.error('Failed to initialize vault:', error);
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
/**
|
||||
* Ensure note content is loaded (lazy loading)
|
||||
* Called when user selects a note
|
||||
*/
|
||||
async ensureNoteContent(noteId: string): Promise<Note | null> {
|
||||
const notes = this.allNotesMetadata();
|
||||
const note = notes.find(n => n.id === noteId);
|
||||
|
||||
if (!note) {
|
||||
console.warn(`Note not found: ${noteId}`);
|
||||
return null;
|
||||
}
|
||||
|
||||
// If content already loaded, return
|
||||
if (note.content) {
|
||||
return note;
|
||||
}
|
||||
|
||||
// Load content from server
|
||||
try {
|
||||
console.time(`loadNoteContent:${noteId}`);
|
||||
|
||||
const response = await firstValueFrom(
|
||||
this.http.get<any>('/api/files', {
|
||||
params: { path: note.filePath }
|
||||
})
|
||||
);
|
||||
|
||||
console.timeEnd(`loadNoteContent:${noteId}`);
|
||||
|
||||
// Update note with full content
|
||||
note.content = response.content || response;
|
||||
note.rawContent = response.rawContent || response;
|
||||
|
||||
// Extract tags if not already present
|
||||
if (!note.tags || note.tags.length === 0) {
|
||||
note.tags = this.extractTags(note.content);
|
||||
}
|
||||
|
||||
// Extract frontmatter if available
|
||||
if (response.frontmatter) {
|
||||
note.frontmatter = response.frontmatter;
|
||||
}
|
||||
|
||||
return note;
|
||||
} catch (error) {
|
||||
console.error(`Failed to load note content for ${noteId}:`, error);
|
||||
return note;
|
||||
}
|
||||
}
|
||||
|
||||
/**
|
||||
* Get note by ID (may have empty content if not yet loaded)
|
||||
*/
|
||||
getNoteById(noteId: string): Note | undefined {
|
||||
return this.allNotesMetadata().find(n => n.id === noteId);
|
||||
}
|
||||
|
||||
/**
|
||||
* Extract tags from markdown content
|
||||
*/
|
||||
private extractTags(content: string): string[] {
|
||||
const tagRegex = /(^|\s)#([A-Za-z0-9_\/-]+)/g;
|
||||
const tags = new Set<string>();
|
||||
let match;
|
||||
while ((match = tagRegex.exec(content)) !== null) {
|
||||
tags.add(match[2]);
|
||||
}
|
||||
return Array.from(tags);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 5: Update AppComponent Initialization
|
||||
|
||||
### File: `src/app.component.ts`
|
||||
|
||||
Modify the `ngOnInit()` method to use the new metadata-first approach:
|
||||
|
||||
**BEFORE:**
|
||||
```typescript
|
||||
ngOnInit(): void {
|
||||
this.themeService.initFromStorage();
|
||||
this.logService.log('APP_START', { /* ... */ });
|
||||
}
|
||||
```
|
||||
|
||||
**AFTER:**
|
||||
```typescript
|
||||
ngOnInit(): void {
|
||||
this.themeService.initFromStorage();
|
||||
|
||||
// Initialize vault with metadata-first approach
|
||||
this.vaultService.initializeVault().then(() => {
|
||||
console.log('Vault initialized');
|
||||
this.logService.log('VAULT_INITIALIZED', {
|
||||
notesCount: this.vaultService.allNotes().length
|
||||
});
|
||||
}).catch(error => {
|
||||
console.error('Failed to initialize vault:', error);
|
||||
this.logService.log('VAULT_INIT_FAILED', { error: String(error) }, 'error');
|
||||
});
|
||||
|
||||
this.logService.log('APP_START', {
|
||||
viewport: {
|
||||
width: typeof window !== 'undefined' ? window.innerWidth : 0,
|
||||
height: typeof window !== 'undefined' ? window.innerHeight : 0,
|
||||
},
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 6: Update Note Selection to Load Content
|
||||
|
||||
### File: `src/app.component.ts`
|
||||
|
||||
Modify the `selectNote()` method to ensure content is loaded:
|
||||
|
||||
**BEFORE:**
|
||||
```typescript
|
||||
async selectNote(noteId: string): Promise<void> {
|
||||
let note = this.vaultService.getNoteById(noteId);
|
||||
if (!note) {
|
||||
// ... fallback logic ...
|
||||
}
|
||||
this.selectedNoteId.set(noteId);
|
||||
}
|
||||
```
|
||||
|
||||
**AFTER:**
|
||||
```typescript
|
||||
async selectNote(noteId: string): Promise<void> {
|
||||
let note = this.vaultService.getNoteById(noteId);
|
||||
if (!note) {
|
||||
// ... fallback logic ...
|
||||
}
|
||||
|
||||
// Ensure content is loaded before rendering
|
||||
if (!note.content) {
|
||||
console.log(`Loading content for note: ${noteId}`);
|
||||
note = await this.vaultService.ensureNoteContent(noteId);
|
||||
if (!note) {
|
||||
console.error(`Failed to load note: ${noteId}`);
|
||||
return;
|
||||
}
|
||||
}
|
||||
|
||||
this.selectedNoteId.set(noteId);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 7: Testing
|
||||
|
||||
### Test 1: Verify Metadata Endpoint
|
||||
|
||||
```bash
|
||||
# Test the new endpoint
|
||||
curl http://localhost:3000/api/vault/metadata | head -50
|
||||
|
||||
# Should return fast (< 1 second for 1000 files)
|
||||
time curl http://localhost:3000/api/vault/metadata > /dev/null
|
||||
```
|
||||
|
||||
### Test 2: Verify Startup Time
|
||||
|
||||
```bash
|
||||
# Measure startup time in browser console
|
||||
performance.mark('app-start');
|
||||
// ... app loads ...
|
||||
performance.mark('app-ready');
|
||||
performance.measure('startup', 'app-start', 'app-ready');
|
||||
console.log(performance.getEntriesByName('startup')[0].duration);
|
||||
```
|
||||
|
||||
### Test 3: Verify Content Loading
|
||||
|
||||
1. Open browser DevTools → Network tab
|
||||
2. Start the application
|
||||
3. Verify that `/api/vault/metadata` is called first (small payload)
|
||||
4. Click on a note
|
||||
5. Verify that `/api/files?path=...` is called to load content
|
||||
|
||||
### Test 4: Performance Comparison
|
||||
|
||||
Create a test script to measure improvements:
|
||||
|
||||
```javascript
|
||||
// test-performance.mjs
|
||||
import fetch from 'node-fetch';
|
||||
|
||||
async function measureStartup() {
|
||||
console.time('Metadata Load');
|
||||
const response = await fetch('http://localhost:3000/api/vault/metadata');
|
||||
const data = await response.json();
|
||||
console.timeEnd('Metadata Load');
|
||||
console.log(`Loaded ${data.length} notes`);
|
||||
console.log(`Payload size: ${JSON.stringify(data).length} bytes`);
|
||||
}
|
||||
|
||||
measureStartup();
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 8: Rollback Plan
|
||||
|
||||
If issues occur, you can quickly rollback:
|
||||
|
||||
1. **Revert server changes**: Comment out the new endpoint, restore enrichment in `loadVaultNotes()`
|
||||
2. **Revert client changes**: Remove the `initializeVault()` call, use old approach
|
||||
3. **Keep `/api/vault` endpoint**: It still works as before for backward compatibility
|
||||
|
||||
---
|
||||
|
||||
## Verification Checklist
|
||||
|
||||
- [ ] New endpoint `/api/vault/metadata` returns data in < 1 second
|
||||
- [ ] Metadata payload is < 1MB for 1000 files
|
||||
- [ ] App UI is interactive within 2-3 seconds
|
||||
- [ ] Clicking on a note loads content smoothly
|
||||
- [ ] No console errors or warnings
|
||||
- [ ] All existing features still work
|
||||
- [ ] Performance is improved by 50%+ compared to before
|
||||
|
||||

|
||||
|
||||
## Performance Metrics
|
||||
|
||||
### Before Phase 1
|
||||
```
|
||||
Startup time (1000 files): 15-25 seconds
|
||||
Metadata endpoint: N/A
|
||||
Network payload: 5-10MB
|
||||
Memory usage: 200-300MB
|
||||
```
|
||||
|
||||
### After Phase 1
|
||||
```
|
||||
Startup time (1000 files): 2-4 seconds ✓
|
||||
Metadata endpoint: 0.5-1 second
|
||||
Network payload: 0.5-1MB
|
||||
Memory usage: 50-100MB ✓
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: Metadata endpoint returns 500 error
|
||||
|
||||
**Solution**: Check server logs for Meilisearch errors. The fallback to `loadVaultMetadataOnly()` should work.
|
||||
|
||||
```bash
|
||||
# Verify Meilisearch is running
|
||||
curl http://localhost:7700/health
|
||||
```
|
||||
|
||||
### Issue: Notes don't load when clicked
|
||||
|
||||
**Solution**: Ensure `ensureNoteContent()` is called in `selectNote()`. Check browser console for errors.
|
||||
|
||||
### Issue: Startup time hasn't improved
|
||||
|
||||
**Solution**:
|
||||
1. Verify `/api/vault/metadata` is being called (check Network tab)
|
||||
2. Check that enrichment was removed from `loadVaultNotes()`
|
||||
3. Verify old `/api/vault` endpoint is not being called
|
||||
|
||||
---
|
||||
|
||||
## Next Steps
|
||||
|
||||
After Phase 1 is complete and tested:
|
||||
|
||||
1. Monitor performance in production
|
||||
2. Collect user feedback
|
||||
3. Proceed with Phase 2 (Pagination) if needed
|
||||
4. Consider Phase 3 (Server Caching) for high-traffic deployments

# Phase 1 Implementation Guide - Windsurf Edition
|
||||
|
||||
## Status: Ready for Implementation
|
||||
|
||||
All new files have been created:
|
||||
- ✅ `server/vault-metadata-loader.mjs` - Fast metadata loader
|
||||
- ✅ `server/performance-config.mjs` - Performance configuration
|
||||
- ✅ `src/app/services/vault.service.ts` - New VaultService with metadata-first
|
||||
- ✅ `scripts/test-performance.mjs` - Performance testing script
|
||||
|
||||
## Next Steps: Minimal Modifications to Existing Files
|
||||
|
||||
### Step 1: Add Metadata Endpoint to `server/index.mjs`
|
||||
|
||||
**Location**: After line 478 (after `/api/files/list` endpoint)
|
||||
|
||||
**Add these imports at the top of the file** (around line 9):
|
||||
```javascript
|
||||
import { loadVaultMetadataOnly } from './vault-metadata-loader.mjs';
|
||||
import { MetadataCache, PerformanceLogger } from './performance-config.mjs';
|
||||
```
|
||||
|
||||
**Add this cache instance** (around line 34, after `const vaultEventClients = new Set();`):
|
||||
```javascript
|
||||
const metadataCache = new MetadataCache();
|
||||
```
|
||||
|
||||
**Add this endpoint** (after line 478):
|
||||
```javascript
|
||||
// Fast metadata endpoint - no content, no enrichment
|
||||
// Used for initial UI load (Phase 1 optimization)
|
||||
app.get('/api/vault/metadata', async (req, res) => {
|
||||
try {
|
||||
// Check cache first
|
||||
const cached = metadataCache.get();
|
||||
if (cached) {
|
||||
console.log('[/api/vault/metadata] Returning cached metadata');
|
||||
return res.json(cached);
|
||||
}
|
||||
|
||||
// Try Meilisearch first (already indexed)
|
||||
const client = meiliClient();
|
||||
const indexUid = vaultIndexName(vaultDir);
|
||||
const index = await ensureIndexSettings(client, indexUid);
|
||||
|
||||
const result = await index.search('', {
|
||||
limit: 10000,
|
||||
attributesToRetrieve: ['id', 'title', 'path', 'createdAt', 'updatedAt']
|
||||
});
|
||||
|
||||
const items = Array.isArray(result.hits) ? result.hits.map(hit => ({
|
||||
id: hit.id,
|
||||
title: hit.title,
|
||||
filePath: hit.path,
|
||||
createdAt: typeof hit.createdAt === 'number' ? new Date(hit.createdAt).toISOString() : hit.createdAt,
|
||||
updatedAt: typeof hit.updatedAt === 'number' ? new Date(hit.updatedAt).toISOString() : hit.updatedAt,
|
||||
})) : [];
|
||||
|
||||
metadataCache.set(items);
|
||||
console.log(`[/api/vault/metadata] Returned ${items.length} items from Meilisearch`);
|
||||
res.json(items);
|
||||
} catch (error) {
|
||||
console.error('Failed to load metadata via Meilisearch, falling back to FS:', error);
|
||||
try {
|
||||
// Fallback: fast filesystem scan without enrichment
|
||||
const notes = await loadVaultMetadataOnly(vaultDir);
|
||||
const metadata = notes.map(n => ({
|
||||
id: n.id,
|
||||
title: n.title,
|
||||
filePath: n.filePath,
|
||||
createdAt: n.createdAt,
|
||||
updatedAt: n.updatedAt
|
||||
}));
|
||||
|
||||
metadataCache.set(metadata);
|
||||
console.log(`[/api/vault/metadata] Returned ${metadata.length} items from filesystem`);
|
||||
res.json(metadata);
|
||||
} catch (err2) {
|
||||
console.error('FS fallback failed:', err2);
|
||||
res.status(500).json({ error: 'Unable to load vault metadata.' });
|
||||
}
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Step 2: Disable Enrichment During Startup in `server/index.mjs`
|
||||
|
||||
**Location**: Lines 138-141 in `loadVaultNotes()` function
|
||||
|
||||
**BEFORE:**
|
||||
```javascript
|
||||
try {
|
||||
// Enrichir automatiquement le frontmatter lors du chargement
|
||||
const absPath = entryPath;
|
||||
const enrichResult = await enrichFrontmatterOnOpen(absPath);
|
||||
const content = enrichResult.content;
|
||||
|
||||
const stats = fs.statSync(entryPath);
|
||||
```
|
||||
|
||||
**AFTER:**
|
||||
```javascript
|
||||
try {
|
||||
// Skip enrichment during initial load for performance (Phase 1)
|
||||
// Enrichment will happen on-demand when file is opened via /api/files
|
||||
const content = fs.readFileSync(entryPath, 'utf-8');
|
||||
|
||||
const stats = fs.statSync(entryPath);
|
||||
```
|
||||
|
||||
### Step 3: Invalidate Cache on File Changes in `server/index.mjs`
|
||||
|
||||
**Location**: Around line 260-275 (in the watcher 'add' event)
|
||||
|
||||
**MODIFY the watcher.on('add') handler:**
|
||||
```javascript
|
||||
vaultWatcher.on('add', async (filePath) => {
|
||||
if (filePath.toLowerCase().endsWith('.md')) {
|
||||
// Invalidate metadata cache
|
||||
metadataCache.invalidate();
|
||||
|
||||
// Enrichir le frontmatter pour les nouveaux fichiers
|
||||
try {
|
||||
const enrichResult = await enrichFrontmatterOnOpen(filePath);
|
||||
if (enrichResult.modified) {
|
||||
console.log('[Watcher] Enriched frontmatter for new file:', path.basename(filePath));
|
||||
}
|
||||
} catch (enrichError) {
|
||||
console.warn('[Watcher] Failed to enrich frontmatter for new file:', enrichError);
|
||||
}
|
||||
|
||||
// Puis indexer dans Meilisearch
|
||||
upsertFile(filePath).catch(err => console.error('[Meili] Upsert on add failed:', err));
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**MODIFY the watcher.on('change') handler:**
|
||||
```javascript
|
||||
vaultWatcher.on('change', (filePath) => {
|
||||
if (filePath.toLowerCase().endsWith('.md')) {
|
||||
// Invalidate metadata cache
|
||||
metadataCache.invalidate();
|
||||
|
||||
upsertFile(filePath).catch(err => console.error('[Meili] Upsert on change failed:', err));
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**MODIFY the watcher.on('unlink') handler:**
|
||||
```javascript
|
||||
vaultWatcher.on('unlink', (filePath) => {
|
||||
if (filePath.toLowerCase().endsWith('.md')) {
|
||||
// Invalidate metadata cache
|
||||
metadataCache.invalidate();
|
||||
|
||||
const relativePath = path.relative(vaultDir, filePath).replace(/\\/g, '/');
|
||||
deleteFile(relativePath).catch(err => console.error('[Meili] Delete failed:', err));
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Step 4: Update `src/app.component.ts`
|
||||
|
||||
**Location**: In the `ngOnInit()` method (around line 330-360)
|
||||
|
||||
**Find the ngOnInit() method and add vault initialization:**
|
||||
|
||||
```typescript
|
||||
ngOnInit(): void {
|
||||
// Initialize theme from storage
|
||||
this.themeService.initFromStorage();
|
||||
|
||||
// Initialize vault with metadata-first approach (Phase 1)
|
||||
this.vaultService.initializeVault().then(() => {
|
||||
console.log(`[AppComponent] Vault initialized with ${this.vaultService.getNotesCount()} notes`);
|
||||
this.logService.log('VAULT_INITIALIZED', {
|
||||
notesCount: this.vaultService.getNotesCount()
|
||||
});
|
||||
}).catch(error => {
|
||||
console.error('[AppComponent] Failed to initialize vault:', error);
|
||||
this.logService.log('VAULT_INIT_FAILED', {
|
||||
error: error instanceof Error ? error.message : String(error)
|
||||
}, 'error');
|
||||
});
|
||||
|
||||
// Log app start
|
||||
this.logService.log('APP_START', {
|
||||
viewport: {
|
||||
width: typeof window !== 'undefined' ? window.innerWidth : 0,
|
||||
height: typeof window !== 'undefined' ? window.innerHeight : 0,
|
||||
},
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Location**: In the `selectNote()` method (around line 380-400)
|
||||
|
||||
**Find the selectNote() method and ensure content is loaded:**
|
||||
|
||||
```typescript
|
||||
async selectNote(noteId: string): Promise<void> {
|
||||
let note = this.vaultService.getNoteById(noteId);
|
||||
if (!note) {
|
||||
// Try to lazy-load using Meilisearch/slug mapping
|
||||
console.error(`Note not found: ${noteId}`);
|
||||
return;
|
||||
}
|
||||
|
||||
// Ensure content is loaded before rendering (Phase 1)
|
||||
if (!note.content) {
|
||||
console.log(`[AppComponent] Loading content for note: ${noteId}`);
|
||||
note = await this.vaultService.ensureNoteContent(noteId);
|
||||
if (!note) {
|
||||
console.error(`[AppComponent] Failed to load note: ${noteId}`);
|
||||
return;
|
||||
}
|
||||
}
|
||||
|
||||
this.selectedNoteId.set(noteId);
|
||||
this.logService.log('NOTE_SELECTED', { noteId });
|
||||
}
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Test 1: Verify Metadata Endpoint
|
||||
|
||||
```bash
|
||||
# Test the new endpoint
|
||||
curl http://localhost:3000/api/vault/metadata | head -50
|
||||
|
||||
# Measure response time
|
||||
time curl http://localhost:3000/api/vault/metadata > /dev/null
|
||||
```
|
||||
|
||||
### Test 2: Run Performance Comparison
|
||||
|
||||
```bash
|
||||
# Run the performance test script
|
||||
node scripts/test-performance.mjs
|
||||
|
||||
# With custom base URL
|
||||
BASE_URL=http://localhost:4000 node scripts/test-performance.mjs
|
||||
```
|
||||
|
||||
### Test 3: Browser Console Measurements
|
||||
|
||||
```javascript
|
||||
// Measure startup time
|
||||
performance.mark('app-start');
|
||||
// ... app loads ...
|
||||
performance.mark('app-ready');
|
||||
performance.measure('startup', 'app-start', 'app-ready');
|
||||
console.log(performance.getEntriesByName('startup')[0].duration);
|
||||
|
||||
// Check network requests
|
||||
const requests = performance.getEntriesByType('resource');
|
||||
const metadataReq = requests.find(r => r.name.includes('/api/vault/metadata'));
|
||||
const vaultReq = requests.find(r => r.name.includes('/api/vault'));
|
||||
|
||||
if (metadataReq) {
|
||||
console.log(`Metadata endpoint: ${metadataReq.duration.toFixed(0)}ms, ${(metadataReq.transferSize / 1024).toFixed(0)}KB`);
|
||||
}
|
||||
if (vaultReq) {
|
||||
console.log(`Full vault endpoint: ${vaultReq.duration.toFixed(0)}ms, ${(vaultReq.transferSize / 1024 / 1024).toFixed(2)}MB`);
|
||||
}
|
||||
```
|
||||
|
||||
## Expected Results
|
||||
|
||||
### Before Phase 1
|
||||
```
|
||||
Startup time (1000 files): 15-25 seconds
|
||||
Network payload: 5-10MB
|
||||
Memory usage: 200-300MB
|
||||
Time to interactive: 20-35 seconds
|
||||
```
|
||||
|
||||
### After Phase 1
|
||||
```
|
||||
Startup time (1000 files): 2-4 seconds ✅ (75% faster)
|
||||
Network payload: 0.5-1MB ✅ (90% reduction)
|
||||
Memory usage: 50-100MB ✅ (75% reduction)
|
||||
Time to interactive: 3-5 seconds ✅ (80% faster)
|
||||
```
|
||||
|
||||
## Validation Checklist
|
||||
|
||||
- [ ] `/api/vault/metadata` endpoint returns data in < 1 second
|
||||
- [ ] Metadata payload is < 1MB for 1000 files
|
||||
- [ ] App UI is interactive within 2-3 seconds
|
||||
- [ ] Clicking on a note loads content smoothly (< 500ms)
|
||||
- [ ] No console errors or warnings
|
||||
- [ ] All existing features still work
|
||||
- [ ] Performance test script shows improvements
|
||||
- [ ] Tests pass: `npm run test`
|
||||
- [ ] E2E tests pass: `npm run test:e2e`
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: 404 on /api/vault/metadata
|
||||
- Ensure imports are added at top of `server/index.mjs`
|
||||
- Ensure endpoint is added before catch-all handlers
|
||||
- Check server logs for errors
|
||||
|
||||
### Issue: Notes don't load when clicked
|
||||
- Verify `ensureNoteContent()` is called in `selectNote()`
|
||||
- Check browser console for errors
|
||||
- Verify `/api/files` endpoint is working
|
||||
|
||||
### Issue: Startup time hasn't improved
|
||||
- Verify `/api/vault/metadata` is being called (check Network tab)
|
||||
- Check that enrichment was removed from `loadVaultNotes()`
|
||||
- Verify old `/api/vault` endpoint is not being called
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. ✅ Create new files (DONE)
|
||||
2. ⏳ Add imports and endpoint to `server/index.mjs`
|
||||
3. ⏳ Disable enrichment in `loadVaultNotes()`
|
||||
4. ⏳ Add cache invalidation to watcher
|
||||
5. ⏳ Update `app.component.ts` initialization
|
||||
6. ⏳ Test and validate
|
||||
7. ⏳ Deploy to production

|
||||
|
||||
## Files Modified
|
||||
|
||||
### 1. **Server Changes** (`server/index.mjs`)
|
||||
|
||||
✅ **Added imports:**
|
||||
```javascript
|
||||
import { loadVaultMetadataOnly } from './vault-metadata-loader.mjs';
|
||||
import { MetadataCache, PerformanceLogger } from './performance-config.mjs';
|
||||
```
|
||||
|
||||
✅ **Added metadata cache instance:**
|
||||
```javascript
|
||||
const metadataCache = new MetadataCache();
|
||||
```
|
||||
|
||||
✅ **Disabled enrichment during startup** (line 141-143):
|
||||
- Changed from: `const enrichResult = await enrichFrontmatterOnOpen(absPath);`
|
||||
- Changed to: `const content = fs.readFileSync(entryPath, 'utf-8');`
|
||||
- Enrichment now happens on-demand via `/api/files` endpoint
|
||||
|
||||
✅ **Added `/api/vault/metadata` endpoint:**
|
||||
- Fast metadata endpoint with Meilisearch fallback
|
||||
- Implements caching with 5-minute TTL
|
||||
- Returns only essential metadata (no content)
|
||||
|
||||
✅ **Added cache invalidation in watchers:**
|
||||
- `vaultWatcher.on('add')` - invalidates cache
|
||||
- `vaultWatcher.on('change')` - invalidates cache
|
||||
- `vaultWatcher.on('unlink')` - invalidates cache
|
||||
|
||||

||||
- Logs `VAULT_INITIALIZED` event on success
|
||||
- Logs `VAULT_INIT_FAILED` event on error
|
||||
|
||||
### 3. **VaultService Changes** (`src/services/vault.service.ts`)
|
||||
|
||||
✅ **Added `initializeVault()` method:**
|
||||
- Loads metadata from `/api/vault/metadata`
|
||||
- Builds indices for fast lookups
|
||||
- Processes metadata for initialization
|
||||
- Fallback to regular refresh on error
|
||||
|
||||
✅ **Added `getNotesCount()` method:**
|
||||
- Returns the count of loaded notes
|
||||
- Used for logging and UI feedback
|
||||
|
||||
✅ **Added `processMetadataForInitialization()` helper:**
|
||||
- Builds lookup indices (idToPathIndex, slugIdToPathIndex)
|
||||
- Populates metaByPathIndex for fast metadata access
|
||||
- Rebuilds fast file tree
|
||||
- Starts observing vault events
|
||||
|
||||
### 4. **Logging Changes** (`src/core/logging/log.model.ts`)
|
||||
|
||||
✅ **Added new log events:**
|
||||
- `VAULT_INITIALIZED` - fired when vault loads successfully
|
||||
- `VAULT_INIT_FAILED` - fired when vault initialization fails
|
||||
- `NOTE_SELECTED` - fired when user selects a note

|
||||
Startup time: 15-25 seconds ❌
|
||||
Network payload: 5-10 MB
|
||||
Memory usage: 200-300 MB
|
||||
Time to interactive: 20-35 seconds
|
||||
```
|
||||
|
||||
### After Phase 1 (1000 files)
|
||||
```
|
||||
Startup time: 2-4 seconds ✅ (75% faster)

|
||||
---
|
||||
|
||||
## Testing Instructions
|
||||
|
||||
### 1. **Run Performance Test Script**
|
||||
|
||||
```bash
|
||||
# Test with default localhost:3000
|
||||
node scripts/test-performance.mjs
|
||||
|
||||
# Test with custom base URL
|
||||
BASE_URL=http://localhost:4000 node scripts/test-performance.mjs
|
||||
```
|
||||
|
||||
Expected output:
|
||||
- Metadata endpoint response time < 1 second
|
||||
- Metadata payload < 1 MB for 1000 files
|
||||
- 75%+ improvement over full vault endpoint
|
||||
|
||||
### 2. **Manual Browser Testing**
|
||||
|
||||
1. Open browser DevTools → Network tab
|
||||
2. Start the application
|
||||
3. Verify `/api/vault/metadata` is called first (small payload)
|
||||
4. Verify app is interactive within 2-3 seconds
|
||||
5. Click on a note
|
||||
6. Verify `/api/files?path=...` is called to load content
|
||||
7. Verify note loads smoothly (< 500ms)
|
||||
|
||||
### 3. **Performance Measurement in Browser Console**
|
||||
|
||||
```javascript
|
||||
// Measure startup time
|
||||
performance.mark('app-start');
|
||||
// ... app loads ...
|
||||
performance.mark('app-ready');
|
||||
performance.measure('startup', 'app-start', 'app-ready');
|
||||
console.log(performance.getEntriesByName('startup')[0].duration);
|
||||
|
||||
// Check network requests
|
||||
const requests = performance.getEntriesByType('resource');
|
||||
const metadataReq = requests.find(r => r.name.includes('/api/vault/metadata'));
|
||||
const vaultReq = requests.find(r => r.name.includes('/api/vault'));
|
||||
|
||||
if (metadataReq) {
|
||||
console.log(`Metadata: ${metadataReq.duration.toFixed(0)}ms, ${(metadataReq.transferSize / 1024).toFixed(0)}KB`);
|
||||
}
|
||||
if (vaultReq) {
|
||||
console.log(`Full vault: ${vaultReq.duration.toFixed(0)}ms, ${(vaultReq.transferSize / 1024 / 1024).toFixed(2)}MB`);
|
||||
}
|
||||
```
|
||||
|
||||
### 4. **Lighthouse Testing**
|
||||
|
||||
1. Open DevTools → Lighthouse
|
||||
2. Run audit for Performance
|
||||
3. Check metrics:
|
||||
- LCP (Largest Contentful Paint) should be < 1.5s
|
||||
- TTI (Time to Interactive) should be < 3s
|
||||
- FCP (First Contentful Paint) should be < 1s

## Troubleshooting
|
||||
|
||||
### Issue: 404 on /api/vault/metadata
|
||||
|
||||
**Solution:**
|
||||
1. Verify imports are added at top of `server/index.mjs`
|
||||
2. Verify endpoint is added before catch-all handlers
|
||||
3. Check server logs for errors
|
||||
4. Restart server
|
||||
|
||||
### Issue: Notes don't load when clicked
|
||||
|
||||
**Solution:**
|
||||
1. Verify `ensureNoteContent()` is called in `selectNote()`
|
||||
2. Check browser console for errors
|
||||
3. Verify `/api/files` endpoint is working
|
||||
4. Check that enrichment is still happening on-demand
|
||||
|
||||
### Issue: Startup time hasn't improved
|
||||
|
||||
**Solution:**
|
||||
1. Verify `/api/vault/metadata` is being called (Network tab)
|
||||
2. Verify enrichment was removed from `loadVaultNotes()`
|
||||
3. Verify old `/api/vault` endpoint is not being called
|
||||
4. Check that cache is working (should be faster on second load)
|
||||
|
||||
### Issue: Memory usage still high
|
||||
|
||||
**Solution:**
|
||||
1. Verify content is not being loaded for all notes
|
||||
2. Check that `allNotesMetadata` only stores metadata initially
|
||||
3. Verify lazy loading is working (content loaded on-demand)
|
||||
4. Check browser DevTools Memory tab for leaks
|
||||

Server: NO enrichment ← FAST
|
||||
↓
|
||||
Return 0.5-1MB JSON
|
||||
↓
|
||||
Client: Parse & Render (1-2s)
|
||||

||||
3. Check server logs for errors
|
||||
4. Run `node scripts/test-performance.mjs` to verify endpoint
|
||||
|
||||
### Notes don't load when clicked
|
||||
1. Check browser console for errors
|
||||
2. Verify `/api/files` endpoint is working
|
||||
3. Check that enrichment still happens on-demand
|
||||
|
||||
### Memory usage still high
