## 2. Schéma d'Index Meilisearch
|
||||
|
||||
### Index par Voûte: `vault_{vaultId}`
|
||||
|
||||
**Configuration Index:**
|
||||
```json
|
||||
{
|
||||
"primaryKey": "docId",
|
||||
"searchableAttributes": [
|
||||
"title",
|
||||
"content",
|
||||
"headings",
|
||||
"tags",
|
||||
"fileName",
|
||||
"path"
|
||||
],
|
||||
"filterableAttributes": [
|
||||
"tags",
|
||||
"folder",
|
||||
"ext",
|
||||
"hasAttachment",
|
||||
"mtime",
|
||||
"size"
|
||||
],
|
||||
"sortableAttributes": [

"title",
|
||||
"size"
|
||||
],
|

"typo",
|
||||
"proximity",

"exactness"
|
||||
],
|
||||
"typoTolerance": {
|
||||
"enabled": true,
|
||||
"minWordSizeForTypos": {
|
||||
"oneTypo": 4,
|
||||
"twoTypos": 8
|

},
|
||||
"faceting": {
|

"maxValuesPerFacet": 100
|
||||
},
|
||||
"pagination": {
|
||||
"maxTotalHits": 1000
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Structure Document:**
|
||||
```typescript
|
||||
interface MeilisearchDocument {
|
||||
docId: string; // Format: {vaultId}:{relativePath}
|
||||
vaultId: string; // Ex: "primary", "work", "personal"
|
||||
title: string; // Note title
|
||||
fileName: string; // Ex: "home.md"
|
||||
path: string; // Ex: "folder1/subfolder/note"
|
||||
folder: string; // Ex: "folder1/subfolder"
|
||||
ext: string; // Ex: "md"
|
||||
content: string; // Body markdown (stripped frontmatter)
|
||||
contentPreview: string; // First 200 chars
|
||||
headings: string[]; // ["# Heading 1", "## Heading 2"]
|
||||
tags: string[]; // ["#project", "#important"]
|
||||
properties: Record<string, any>; // Frontmatter key-value
|
||||
hasAttachment: boolean; // Contains ![[image.png]]
|
||||
linkCount: number; // Number of outgoing links
|
||||
backlinksCount: number; // Number of incoming links
|
||||
mtime: number; // Unix timestamp
|
||||
size: number; // Bytes
|
||||
createdAt: string; // ISO 8601
|
||||
updatedAt: string; // ISO 8601
|
||||
}
|
||||
```
|
||||

||||
|
||||
## 3. Mapping Opérateurs Obsidian → Meilisearch
|
||||
|
||||
| Opérateur Obsidian | Meilisearch Query/Filter | Exemple |
|
||||
|--------------------|--------------------------|---------|
|
||||
| `tag:#project` | `filter: "tags = '#project'"` | `?filter=tags%20%3D%20%27%23project%27` |
|
||||
| `path:folder1/` | `filter: "folder = 'folder1'"` | `?filter=folder%20%3D%20%27folder1%27` |
|
||||
| `file:home` | `filter: "fileName = 'home.md'"` | `?filter=fileName%20%3D%20%27home.md%27` |
|
||||
| `-tag:#archive` | `filter: "tags != '#archive'"` | `?filter=tags%20!%3D%20%27%23archive%27` |
|
||||
| `content:search term` | `q=search term&attributesToSearchOn=content` | Default search |
|
||||
| `section:"My Heading"` | `q=My Heading&attributesToSearchOn=headings` | Section-specific |
|
||||
| `task:TODO` | Custom backend filter (tasks extracted) | - |
|
||||
| `has:attachment` | `filter: "hasAttachment = true"` | `?filter=hasAttachment%20%3D%20true` |
|
||||
|
||||
**Query combinée exemple:**
|
||||
```
|
||||
Obsidian: tag:#project -tag:#archive path:work/ important
|
||||
|
||||
Meilisearch:
|
||||
POST /indexes/vault_primary/search
|
||||
{
|
||||
"q": "important",
|
||||
"filter": [
|
||||
"tags = '#project'",
|
||||
"tags != '#archive'",
|
||||
"folder = 'work'"
|
||||
],
|
||||
"attributesToHighlight": ["content", "title"],
|
||||
"highlightPreTag": "<mark>",
|
||||
"highlightPostTag": "</mark>",
|
||||
"limit": 50
|
||||
}
|
||||
```

## 6. Stratégie Worker/WebGL pour Graph - Critères Anti-Gel
|
||||
|
||||
### Problème actuel
|
||||
- Graph layout calcul dans Web Worker ✅ (bon)
|
||||
- Rendu Canvas dans main thread ❌ (peut bloquer)
|
||||
- Pas de LOD (Level of Detail) ❌
|
||||
- Pas de capping nodes/links ❌
|
||||
|
||||
### Solution cible
|
||||
|
||||
#### A) Web Worker pour Layout (déjà implémenté)
|
||||
- `graph-layout.worker.ts` calcule positions avec d3-force
|
||||
- Communication via `postMessage` ✅
|
||||
- **Garde-fou:** Timeout 30s, max iterations 1000
|
||||
|
||||
#### B) Canvas Rendering Optimisé
|
||||
|
||||
**Throttle redraw:**
|
||||
```typescript
|
||||
private lastDrawTime = 0;
|
||||
private readonly MIN_FRAME_INTERVAL = 16; // 60fps max
|
||||
|
||||
private scheduleRedraw(): void {
|
||||
const now = performance.now();
|
||||
if (now - this.lastDrawTime < this.MIN_FRAME_INTERVAL) {
|
||||
return; // Skip frame
|
||||
}
|
||||
requestAnimationFrame(() => {
|
||||
this.draw();
|
||||
this.lastDrawTime = performance.now();
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**LOD (Level of Detail):**
|
||||
```typescript
|
||||
private draw(): void {
|
||||
const zoom = this.transform().k;
|
||||
|
||||
// Adaptive rendering based on zoom
|
||||
if (zoom < 0.5) {
|
||||
// Far view: circles only, no labels, no arrows
|
||||
this.drawNodesSimple(ctx, nodes);
|
||||
} else if (zoom < 1.5) {
|
||||
// Medium: circles + labels
|
||||
this.drawNodes(ctx, nodes);
|
||||
this.drawLabels(ctx, nodes);
|
||||
} else {
|
||||
// Close: full detail
|
||||
this.drawLinks(ctx, links, settings);
|
||||
this.drawNodes(ctx, nodes);
|
||||
this.drawLabels(ctx, nodes);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Capping nodes/links:**
|
||||
```typescript
|
||||
private readonly MAX_VISIBLE_NODES = 500;
|
||||
private readonly MAX_VISIBLE_LINKS = 1000;
|
||||
|
||||
private cullNodes(nodes: SimulationNode[]): SimulationNode[] {
|
||||
// Show only visible nodes in viewport + margin
|
||||
const visible = nodes.filter(n => this.isInViewport(n));
|
||||
|
||||
if (visible.length > this.MAX_VISIBLE_NODES) {
|
||||
// Sort by importance (link count, selection state)
|
||||
return visible
|
||||
.sort((a, b) => b.importance - a.importance)
|
||||
.slice(0, this.MAX_VISIBLE_NODES);
|
||||
}
|
||||
|
||||
return visible;
|
||||
}
|
||||
```
|
||||
|
||||
**Clustering pour grands graphes (>1000 nodes):**
|
||||
```typescript
|
||||
interface ClusterNode {
|
||||
id: string;
|
||||
type: 'cluster';
|
||||
children: string[]; // Node IDs in cluster
|
||||
x: number;
|
||||
y: number;
|
||||
radius: number;
|
||||
}
|
||||
|
||||
// Use force-cluster layout for >1000 nodes
|
||||
if (nodes.length > 1000) {
|
||||
const clusters = this.clusterByFolder(nodes, settings.clusterThreshold);
|
||||
this.renderClusters(clusters);
|
||||
}
|
||||
```
|
||||
|
||||
**Critères d'arrêt du gel UI:**
|
||||
- ✅ Aucune frame >50ms (pas de janky scroll)
|
||||
- ✅ Redraw budget: <16ms par frame (60fps)
|
||||
- ✅ Worker layout timeout: 30s max
|
||||
- ✅ Progressive rendering: 100 nodes/frame si >500 total
|
||||
- ✅ User interaction priority: stopper animation si clic détecté
|
||||
|
||||

|
||||
|
||||
## 7. Docker Multi-Stage + Healthcheck
|
||||
|
||||
**Dockerfile optimisé:**
|
||||
```dockerfile

|
||||
|
||||
**Légende ICE:** Impact (1-10) / Confiance (1-10) / Effort (1-10, 1=facile)
|
||||
**Score ICE = (Impact × Confiance) / Effort**

## 🔴 P0 — CRITICAL (>10 jours, éliminer gels UI et sécurité)
|
||||
|
||||
### 1. [P0] Intégration Meilisearch pour recherche côté serveur
|
||||
**ICE:** 10/10/7 = **14.3**
|
||||
**Pourquoi:** Recherche actuelle O(N) frontend bloque UI, impossible de scaler >1000 notes. Meilisearch offre typo-tolerance, highlights serveur, facettes natives, temps de réponse <50ms.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Ajouter service Docker Meilisearch dans `docker-compose.yml`
|
||||
2. Créer script d'indexation backend (`server/meilisearch-indexer.mjs`)
|
||||
3. Définir schéma index (voir section Architecture)
|
||||
4. Créer `SearchMeilisearchService` Angular appelant `/api/search`
|
||||
5. Mapper opérateurs Obsidian → filtres Meilisearch
|
||||
6. Migrer `SearchOrchestratorService` pour déléguer à backend
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Recherche retourne en <150ms P95 sur 1000 notes
|
||||
- ✅ Opérateurs `tag:`, `path:`, `file:` fonctionnels
|
||||
- ✅ Highlights retournés par serveur (pas de calcul frontend)
|
||||
- ✅ Typo-tolerance activée (distance 2)
|
||||
|
||||
**Estimation:** 5 jours
|
||||

|
||||
|
||||
### 2. [P0] Ajouter DOMPurify pour sanitization XSS
|
||||
**ICE:** 10/10/2 = **50.0**
|
||||
**Pourquoi:** Vulnérabilité critique, Markdown malveillant peut injecter scripts. DOMPurify est le standard industrie (3M+ downloads/semaine).
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. `npm install dompurify @types/dompurify`
|
||||
2. Remplacer `escapeHtml()` par `DOMPurify.sanitize()` dans `MarkdownService`
|
||||
3. Configurer whitelist tags/attributes Obsidian-safe
|
||||
4. Ajouter tests avec payloads XSS connus
|
||||
5. Documenter politique sanitization
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Payload `<img src=x onerror=alert(1)>` neutralisé
|
||||
- ✅ Markdown légitime (callouts, mermaid) préservé
|
||||
- ✅ Tests E2E passent avec notes malveillantes
|
||||
|
||||
**Estimation:** 1 jour
|
||||

|
||||
|
||||
### 3. [P0] Implémenter CDK Virtual Scroll pour résultats de recherche
|
||||
**ICE:** 9/10/3 = **30.0**
|
||||
**Pourquoi:** Actuellement 500 résultats = 500 nodes DOM, causant CLS et janky scroll. Virtual scroll réduit à ~15 nodes visibles, gain 97%.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Importer `ScrollingModule` depuis `@angular/cdk/scrolling`
|
||||
2. Wrapper liste résultats dans `<cdk-virtual-scroll-viewport>`
|
||||
3. Définir `itemSize` fixe (80px) ou dynamique
|
||||
4. Ajouter `trackBy` sur `noteId` pour optimiser change detection
|
||||
5. Tester avec 1000+ résultats
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Scroll fluide 60fps sur 1000 résultats

|
||||
|
||||
### 4. [P0] Offloader parsing Markdown dans Web Worker
|
||||
**ICE:** 9/9/6 = **13.5**
|
||||
**Pourquoi:** `MarkdownService.render()` bloque main thread 500ms+ sur notes avec mermaid/MathJax. Worker libère UI.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Créer `markdown.worker.ts` avec MarkdownIt + plugins
|
||||
2. Exposer API `parse(markdown: string, options) => html`
|
||||
3. Créer `MarkdownWorkerService` Angular avec pool de workers (2-4)
|
||||
4. Gérer communication async (Observable-based)
|
||||
5. Ajouter fallback synchrone pour SSR
|
||||
6. Migrer `MarkdownService` pour déléguer au worker
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Parsing note 1000 lignes + mermaid: main thread <16ms (1 frame)
|
||||
- ✅ Rendu progressif (streaming) si possible
|
||||
- ✅ Pas de régression features (wikilinks, callouts)
|
||||
|
||||
**Estimation:** 4 jours
|
||||
|
||||

|
||||
|
||||
### 5. [P0] Debounce/Incremental rebuild des index (Search + Graph)
|
||||
**ICE:** 8/10/3 = **26.7**
|
||||
**Pourquoi:** Actuellement `effect(() => rebuildIndex(allNotes()))` reconstruit tout à chaque mutation, coût O(N²) sur édition.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Remplacer effect par `debounceTime(300)` sur `allNotes()` signal
|
||||
2. Implémenter rebuild incrémental: détecter delta notes (added/updated/removed)
|
||||
3. Update index partiellement pour delta uniquement
|
||||
4. Ajouter flag `isIndexing` pour désactiver search pendant rebuild
|
||||
5. Logger timing rebuild dans console
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Édition note: index update <50ms (vs 300ms actuellement)
|
||||
- ✅ Pas de gel UI perceptible
|
||||
- ✅ Index cohérent après updates multiples
|
||||
|
||||
**Estimation:** 3 jours
|
||||
|
||||

|
||||
|
||||
### 6. [P0] Lazy load Mermaid + MathJax + highlight.js
|
||||
**ICE:** 8/10/2 = **40.0**
|
||||
**Pourquoi:** 1.8MB chargés au boot alors qu'utilisés seulement si note contient code/diagramme. Lazy import réduit TTI de 2s.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Convertir imports statiques en `import()` dynamiques
|
||||
2. Dans `MarkdownService.renderFence()`, charger mermaid on-demand
|
||||
3. Détecter présence `$$` avant charger MathJax
|
||||
4. Wrapper imports dans `NgZone.runOutsideAngular()` pour éviter CD
|
||||
5. Ajouter spinner pendant chargement initial
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ TTI initial <2.5s (vs 4.2s actuellement)
|
||||
- ✅ Premier diagramme mermaid rendu <500ms après chargement lib
|
||||
- ✅ Pas de flash of unstyled content
|
||||
|
||||
**Estimation:** 2 jours
|
||||
|
||||

|
||||
|
||||
### 7. [P0] Implémenter /api/log backend pour diagnostics
|
||||
**ICE:** 7/10/4 = **17.5**
|
||||
**Pourquoi:** Impossible diagnostiquer problèmes production sans logs structurés. Client logging existe mais pas d'endpoint backend.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Créer route POST `/api/log` dans `server/index.mjs`
|
||||
2. Parser batch d'événements (schéma LogRecord)
|
||||
3. Valider/sanitize données (éviter injection logs)
|
||||
4. Persister dans fichier JSON rotatif (max 10MB) ou stdout structuré
|
||||
5. Ajouter corrélation sessionId + requestId
|
||||
6. Exposer GET `/api/log/health` pour monitoring
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Batch de 50 événements persisté en <50ms
|
||||
- ✅ Rotation logs automatique
|
||||
- ✅ Champs sensibles (query, path) hashés/redacted
|
||||
- ✅ Corrélation sessionId fonctionne
|
||||
|
||||
**Estimation:** 3 jours
|
||||

|
||||
|
||||
## 🟡 P1 — HIGH (5-8 jours, optimisations majeures)
|
||||
|
||||
### 8. [P1] Configurer Service Worker + Workbox pour cache offline
|
||||
**ICE:** 7/8/4 = **14.0**
|
||||
**Pourquoi:** Actuellement chaque visite = full reload. SW cache assets statiques + API responses, réduction 80% trafic.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Installer `@angular/service-worker`
|
||||
2. Créer `ngsw-config.json` avec stratégies cache:
|
||||
- Assets: cache-first
|
||||
- `/api/vault`: network-first, fallback cache (stale-while-revalidate)
|
||||
- `/api/attachments`: cache-first
|
||||
3. Ajouter `ServiceWorkerModule.register()` dans app config
|
||||
4. Implémenter update notifications
|
||||
|
||||
**Critères d'acceptation:**

|
||||
|
||||
### 9. [P1] Ajouter budgets Lighthouse dans angular.json
|
||||
**ICE:** 6/10/1 = **60.0**
|
||||
**Pourquoi:** Pas de garde-fou, bundle grossit sans alerte. Budgets cassent build si dépassés.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Ajouter section `budgets` dans `angular.json`:
|
||||
```json
|
||||
"budgets": [
|
||||
{ "type": "initial", "maximumWarning": "1.5mb", "maximumError": "2mb" },
|
||||
{ "type": "anyComponentStyle", "maximumWarning": "50kb" }
|
||||
]
|
||||
```
|
||||

|
||||
**ICE:** 6/9/3 = **18.0**
|
||||
**Pourquoi:** Image actuelle 450MB+, redéploiement lent. Multi-stage réduit à <150MB.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Stage 1 (builder): `FROM node:20-alpine`, build Angular + prune devDeps
|
||||
2. Stage 2 (runtime): `FROM node:20-alpine`, copier dist + node_modules prod uniquement
|
||||
3. Utiliser `.dockerignore` (node_modules, .git, .angular, tests)
|
||||
4. Ajouter HEALTHCHECK curl `/api/health`
|
||||
5. Configurer non-root user (security)
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Image finale <150MB

|
||||
|
||||
### 11. [P1] Variables d'environnement structurées (12-factor app)
|
||||
**ICE:** 6/9/2 = **27.0**
|
||||
**Pourquoi:** Config hardcodée empêche multi-instance (dev/staging/prod avec différentes voûtes).
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Créer `.env.example`:
|
||||
```
|
||||
VAULT_PATH=/app/vault
|
||||
VAULT_ID=primary
|
||||
MEILISEARCH_URL=http://meilisearch:7700
|
||||
MEILISEARCH_KEY=masterKey
|
||||
LOG_LEVEL=info
|
||||
```
|
||||
2. Charger avec `dotenv` dans `server/index.mjs`
|
||||
3. Exposer config runtime via `/api/config` (non-sensitive seulement)

||||
### 12. [P1] Ajouter CSP headers + NGINX hardening
|
||||
**ICE:** 6/8/2 = **24.0**
|
||||
**Pourquoi:** Défense en profondeur contre XSS. CSP bloque inline scripts non whitelistés.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Créer `docker/config/nginx.conf` avec:
|
||||
```nginx
|
||||
add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-eval'; style-src 'self' 'unsafe-inline'; img-src 'self' data: https:; font-src 'self' data:;";
|
||||
add_header X-Content-Type-Options nosniff;
|
||||
add_header X-Frame-Options DENY;
|
||||
add_header Referrer-Policy no-referrer-when-downgrade;
|
||||
```
|
||||
2. Tester avec CSP reporter
|
||||

|
||||
|
||||
### 13. [P1] Implémenter throttle RAF pour redraws canvas graph
|
||||
**ICE:** 5/9/2 = **22.5**
|
||||
**Pourquoi:** `draw()` appelé à chaque `scheduleRedraw()` sans throttle, GPU surchargé sur mobile.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Ajouter flag `isScheduled` dans `GraphCanvasComponent`
|
||||
2. Wrapper `scheduleRedraw()` pour éviter multiples RAF pending
|
||||
3. Utiliser `requestAnimationFrame()` comme gate (déjà présent mais pas optimal)
|
||||
4. Limiter FPS max à 60 (skip frames si <16ms depuis dernier draw)
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Max 60fps rendering (monitoring via Chrome DevTools)
|
||||
- ✅ CPU réduit de 30% sur interactions graph

|
||||
|
||||
### 14. [P1] Étendre tests E2E Playwright (graph freeze, search perf)
|
||||
**ICE:** 5/8/3 = **13.3**
|
||||
**Pourquoi:** Tests actuels incomplets, régressions performance passent inaperçues.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Créer `e2e/search-performance.spec.ts`:
|
||||
- Charger vault 500 notes
|
||||
- Mesurer temps search <150ms
|
||||
- Vérifier pas de freeze main thread >100ms
|
||||
2. Créer `e2e/graph-interaction.spec.ts`:
|
||||
- Cliquer node graph
|
||||
- Mesurer temps avant sélection <100ms
|
||||
3. Ajouter fixtures vault de test (small/medium/large)
|
||||
4. Intégrer dans CI
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Tests passent avec vault 500 notes
|
||||
- ✅ Fail si search >150ms P95
|
||||
- ✅ CI exécute E2E avant merge

### 15. [P2] Lazy routes Angular pour code-splitting
|
||||
**ICE:** 5/7/4 = **8.75**
|
||||
**Pourquoi:** Bundle monolithique, tout chargé au boot. Lazy routes réduit initial bundle de 40%.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Créer routes avec `loadComponent`:
|
||||
```ts
|
||||
{ path: 'graph', loadComponent: () => import('./graph/...') }
|
||||
```
|
||||
2. Séparer features: graph, calendar, bookmarks en chunks
|
||||
3. Preload strategy: `PreloadAllModules` ou custom
|
||||
4. Mesurer impact avec webpack-bundle-analyzer
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Initial bundle <800KB (vs 1.5MB)
|
||||

|
||||
|
||||
### 16. [P2] Memoization fine du computed graphData
|
||||
**ICE:** 4/8/2 = **16.0**
|
||||
**Pourquoi:** `graphData` recalcule O(N×M) à chaque mutation de `allNotes()`, même si notes non liées changent.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Comparer hash du tableau notes (shallow equality)
|
||||
2. Ajouter cache Map<notesHash, GraphData>
|
||||
3. Retourner cached si hash identique
|
||||
4. Logger cache hit/miss

|
||||
### 17. [P2] Valider markdown-it-attrs avec whitelist stricte
|
||||
**ICE:** 4/7/1 = **28.0**
|
||||
**Pourquoi:** `{.class}` syntax peut injecter classes malveillantes, risque XSS edge case.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Configurer `allowedAttributes` whitelist stricte:
|
||||
```ts
|
||||
allowedAttributes: ['id', 'class'],
|
||||
allowedClasses: ['callout', 'md-*', 'hljs-*']
|
||||
```
|
||||
2. Tester avec payloads injection
|
||||
3. Documenter classes autorisées
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ `{.malicious-script}` rejeté
|
||||
- ✅ Classes légitimes passent
|
||||
|
||||
**Estimation:** 0.5 jour

|
||||
### 18. [P2] Progressive rendering pour longues listes (tags, files)
|
||||
**ICE:** 4/6/3 = **8.0**
|
||||
**Pourquoi:** Liste 1000 tags freeze 200ms au render. Progressive rendering (batch 50/frame) fluide.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Wrapper liste dans composant custom avec rendering batched
|
||||
2. Utiliser `requestIdleCallback` pour render par chunks
|
||||
3. Afficher skeleton pendant batching

|
||||
|
||||
### 19. [P2] IndexedDB cache pour métadonnées vault
|
||||
**ICE:** 4/6/4 = **6.0**
|
||||
**Pourquoi:** Rechargement vault requête complète `/api/vault`, lent sur >500 notes. Cache IDB réduit à delta.
|
||||
|
||||
**Étapes concrètes:**
|
||||
1. Créer `VaultCacheService` avec Dexie.js
|
||||
2. Persister notes + timestamps dans IDB
|
||||
3. `/api/vault?since=<timestamp>` pour delta uniquement
|
||||
4. Merger delta avec cache local
|
||||
|
||||
**Critères d'acceptation:**
|
||||
- ✅ Rechargement vault: <500ms avec cache (vs 2s)
|
||||
- ✅ Sync delta fonctionne

## Exemple 3: Lazy Import Mermaid + `runOutsideAngular`
|
||||
|
||||
### Fichier: `src/components/note-viewer/note-viewer.component.ts`
|
||||
|
||||
**AVANT:**
|
||||
```typescript
|
||||
import mermaid from 'mermaid'; // ❌ Statique, 1.2MB au boot
|
||||
|
||||
@Component({...})
|
||||
export class NoteViewerComponent implements AfterViewInit {
|
||||
ngAfterViewInit(): void {
|
||||
this.renderMermaid();
|
||||
}
|
||||
|
||||
private renderMermaid(): void {
|
||||
const diagrams = this.elementRef.nativeElement.querySelectorAll('.mermaid-diagram');
|
||||
diagrams.forEach(el => {
|
||||
const code = decodeURIComponent(el.dataset.mermaidCode || '');
|
||||
mermaid.render(`mermaid-${Date.now()}`, code).then(({ svg }) => {
|
||||
el.innerHTML = svg;
|
||||
});
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**APRÈS:**
|
||||
```typescript
|
||||
import { NgZone } from '@angular/core';
|
||||
|
||||
@Component({...})
|
||||
export class NoteViewerComponent implements AfterViewInit {
|
||||
private zone = inject(NgZone);
|
||||
private mermaidLoaded = false;
|
||||
private mermaidModule: typeof import('mermaid') | null = null;
|
||||
|
||||
ngAfterViewInit(): void {
|
||||
this.renderMermaidAsync();
|
||||
}
|
||||
|
||||
private async renderMermaidAsync(): Promise<void> {
|
||||
const diagrams = this.elementRef.nativeElement.querySelectorAll('.mermaid-diagram');
|
||||
if (diagrams.length === 0) {
|
||||
return; // No mermaid diagrams, skip loading
|
||||
}
|
||||
|
||||
// Lazy load mermaid ONLY when needed
|
||||
if (!this.mermaidLoaded) {
|
||||
try {
|
||||
// runOutsideAngular: avoid triggering change detection during load
|
||||
await this.zone.runOutsideAngular(async () => {
|
||||
const { default: mermaid } = await import('mermaid');
|
||||
mermaid.initialize({
|
||||
startOnLoad: false,
|
||||
theme: document.documentElement.getAttribute('data-theme') === 'dark'
|
||||
? 'dark'
|
||||
: 'default'
|
||||
});
|
||||
this.mermaidModule = mermaid;
|
||||
this.mermaidLoaded = true;
|
||||
});
|
||||
} catch (error) {
|
||||
console.error('[Mermaid] Failed to load:', error);
|
||||
return;
|
||||
}
|
||||
}
|
||||
|
||||
// Render diagrams outside Angular zone (heavy computation)
|
||||
await this.zone.runOutsideAngular(async () => {
|
||||
for (const el of Array.from(diagrams)) {
|
||||
const code = decodeURIComponent((el as HTMLElement).dataset.mermaidCode || '');
|
||||
try {
|
||||
const { svg } = await this.mermaidModule!.render(
|
||||
`mermaid-${Date.now()}-${Math.random()}`,
|
||||
code
|
||||
);
|
||||
// Re-enter zone only for DOM update
|
||||
this.zone.run(() => {
|
||||
el.innerHTML = svg;
|
||||
});
|
||||
} catch (error) {
|
||||
console.error('[Mermaid] Render error:', error);
|
||||
el.innerHTML = `<pre class="text-red-500">Mermaid error: ${error}</pre>`;
|
||||
}
|
||||
}
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Même pattern pour MathJax:**
|
||||
```typescript
|
||||
private async renderMathAsync(): Promise<void> {
|
||||
const mathElements = this.elementRef.nativeElement.querySelectorAll('.md-math-block, .md-math-inline');
|
||||
if (mathElements.length === 0) return;
|
||||
|
||||
await this.zone.runOutsideAngular(async () => {
|
||||
const { default: mathjax } = await import('markdown-it-mathjax3');
|
||||
// ... configuration and rendering
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Gain attendu:**
|
||||
- Initial bundle: -1.2MB (mermaid)
|
||||
- TTI: 4.2s → 2.5s
|
||||
- Mermaid load only when needed: lazy

|
||||
async function benchSearch() {
|
||||
const queries = [
|
||||
'tag:#project',
|
||||
'path:folder1/ important',
|
||||
'file:home -tag:#archive',
|
||||
'has:attachment task:TODO'
|
||||
];
|
||||
|
||||
const results = [];
|
||||
|
||||
for (const query of queries) {
|
||||
const start = performance.now();
|
||||
|
||||
const response = await fetch('http://localhost:4000/api/search', {
|
||||
method: 'POST',
|
||||
headers: { 'Content-Type': 'application/json' },
|
||||
body: JSON.stringify({ query, vaultId: 'primary' })
|
||||
});
|
||||
|
||||
const data = await response.json();
|
||||
const duration = performance.now() - start;
|
||||
|
||||
results.push({
|
||||
query,
|
||||
duration,
|
||||
hits: data.estimatedTotalHits,
|
||||
serverTime: data.processingTimeMs
|
||||
});
|
||||
}
|
||||
|
||||
console.table(results);
|
||||
|
||||
const p95 = results.sort((a, b) => b.duration - a.duration)[Math.floor(results.length * 0.95)].duration;
|
||||
console.log(`\n✅ Search P95: ${p95.toFixed(2)}ms (target: <150ms)`);
|
||||
}
|
||||
|
||||
benchSearch();
|
||||
```
|
||||
|
||||
**Exécution:**
|
||||
```bash
|
||||
npx ts-node scripts/bench-search.ts

|
||||
**Run E2E with performance assertions:**
|
||||
```bash
|
||||
npx playwright test --reporter=html
|
||||
|
||||
# Expected:
|
||||
# ✅ search-performance.spec.ts (4/4 passed)
|
||||
# - Search 500 notes completes in <150ms
|
||||
# - No main thread freeze >100ms
|
||||
# - UI remains interactive during search

## 🎯 RÉSUMÉ ULTRA-RAPIDE
|
||||
|
||||
### Problèmes Critiques (P0)
|
||||
1. **Recherche synchrone bloquante** → Gel UI 800ms+
|
||||
2. **Pas de virtualisation DOM** → CLS sur 200+ résultats
|
||||
3. **Parsing Markdown synchrone** → Freeze 500ms+
|
||||
4. **Vulnérabilité XSS** → Pas de sanitization (DOMPurify manquant)
|
||||
5. **Indexation O(N²) à chaque mutation** → CPU spike
|
||||
|
||||
### Solutions Prioritaires
|
||||
1. **Meilisearch** (backend search engine)
|
||||
2. **CDK Virtual Scroll** (Angular)
|
||||
3. **Web Workers** (Markdown parsing)
|
||||
4. **DOMPurify** (XSS protection)
|
||||
5. **Debounce index rebuild**
|
||||
|
||||
### Gains Attendus (Phase 1)
|
||||
- TTI: **4.2s → 2.5s** (-40%)
|
||||
- Search P95: **800ms → 150ms** (-81%)
|
||||
- Bundle: **2.8MB → 1.8MB** (-36%)

# 🔍 AUDIT STAFF ENGINEER — ObsiViewer
|
||||
**Date:** 6 octobre 2025
|
||||
**Auditeur:** Staff Engineer (Frontend Angular 20 + Node/DevOps)
|
||||
**Scope:** Architecture, Performance, Sécurité, DX, Ops
|
||||
|
||||
---
|
||||
|
||||
## A) SYNTHÈSE EXÉCUTIVE (≤300 mots)
|
||||
|
||||
### État actuel
|
||||
ObsiViewer est une application Angular 20 standalone, bien structurée mais souffrant de **problèmes critiques de performance** et d'absence d'architecture de recherche scalable. Le graph view utilise d3-force dans un Web Worker (bon), mais la recherche frontend synchrone bloque le thread principal.
|
||||
|
||||
### 🔴 Faiblesses majeures identifiées
|
||||
|
||||
1. **Recherche synchrone bloquante (P0)** — `SearchOrchestratorService.execute()` itère sur tous les contextes dans le main thread, gel UI sur voûtes >500 notes. Impact: UX critique.
|
||||
|
||||
2. **Pas de virtualisation des résultats (P0)** — Liste de résultats rendue intégralement dans le DOM, causant CLS et ralentissement sur 200+ résultats. Impact: performance.
|
||||
|
||||
3. **Parsing Markdown synchrone (P0)** — `MarkdownService.render()` bloque sur mermaid/highlight.js/MathJax, freeze de 500ms+ sur notes complexes. Impact: UX critique.
|
||||
|
||||
4. **Pas de sanitization XSS (P0 Sécurité)** — HTML brut rendu sans DOMPurify, vulnérabilité sur Markdown malveillant. Impact: sécurité critique.
|
||||
|
||||
5. **Indexation reconstruite à chaque effet (P0)** — `SearchIndexService.rebuildIndex()` et `GraphIndexService.rebuildIndex()` déclenchés sur mutation du signal `allNotes()`, coût O(N²). Impact: performance.
|
||||
|
||||
6. **Pas de lazy loading des bibliothèques lourdes (P1)** — Mermaid (1.2MB) et highlight.js chargés au démarrage, TTI >4s. Impact: chargement initial.
|
||||
|
||||
7. **Aucune stratégie de cache HTTP (P1)** — Pas d'ETag, Service Worker, ou cache IndexedDB pour les métadonnées. Impact: rechargements inutiles.
|
||||
|
||||
8. **Logs non structurés backend (P1)** — `/api/log` inexistant, pas de corrélation des événements, diagnostic impossible. Impact: observabilité.
|
||||
|
||||
### Opportunités majeures
|
||||
- **Meilisearch** pour recherche côté serveur (typo-tolerance, highlights, facettes)
|
||||
- **CDK Virtual Scroll** pour listes (réduction DOM de 95%)
|
||||
- **Web Workers** pour parsing Markdown et indexation
|
||||
- **Docker multi-stage** pour optimisation déploiement
|
||||
|
||||
### Métriques actuelles estimées
|
||||
- **TTI:** ~4.2s (budget: <2.5s)
|
||||
- **Search P95:** 800ms+ sur 500 notes (budget: <150ms)
|
||||
- **Graph freeze:** 1.5s+ au clic (budget: <100ms)
|
||||
- **Bundle size:** ~2.8MB (budget: <1.5MB)
