# TASK-010B: Preview "No HOME Component" Bug - Status Actuel
**Date**: 12 janvier 2026, 11:40
**Status**: 🔴 EN COURS - CRITIQUE
**Priority**: P0 - BLOQUEUR ABSOLU
## 🚨 Symptômes Actuels
**Le preview ne fonctionne JAMAIS après création de projet**
### Ce que l'utilisateur voit:

---
## 📋 Historique des Tentatives de Fix
### Tentative #1 (8 janvier): LocalTemplateProvider avec chemins relatifs
**Status**: ❌ ÉCHOUÉ
**Problème**: Résolution de chemin avec `__dirname` ne fonctionne pas dans webpack
**Erreur**: `Template not found at: ./project-examples/...`
### Tentative #2 (8 janvier): LocalTemplateProvider avec process.cwd()
**Status**: ❌ ÉCHOUÉ
**Problème**: `process.cwd()` pointe vers le mauvais répertoire
**Erreur**: `Template not found at: /Users/tw/.../packages/noodl-editor/project-examples/...`
### Tentative #3 (9 janvier): Génération programmatique
**Status**: ❌ ÉCHOUÉ
**Problème**: Structure JSON incomplète
**Erreur**: `Cannot read properties of undefined (reading 'comments')`
**Résolution**: Ajout du champ `comments: []` dans la structure
### Tentative #4 (12 janvier - AUJOURD'HUI): Fix rootComponent
**Status**: 🟡 EN TEST
**Changements**:
1. Ajout de `rootComponent: 'App'` dans `hello-world.template.ts`
2. Ajout du type `rootComponent?: string` dans `ProjectTemplate.ts`
3. Modification de `ProjectModel.fromJSON()` pour gérer `rootComponent`
**Fichiers modifiés**:
- `packages/noodl-editor/src/editor/src/models/template/templates/hello-world.template.ts`
- `packages/noodl-editor/src/editor/src/models/template/ProjectTemplate.ts`
- `packages/noodl-editor/src/editor/src/models/projectmodel.ts`
**Hypothèse**: Le runtime attend une propriété `rootComponent` dans le project.json pour savoir quel composant afficher dans le preview.
**Résultat**: ⏳ ATTENTE DE CONFIRMATION - L'utilisateur rapporte que ça ne fonctionne toujours pas
---
## 🔍 Analyse du Problème Actuel
### Questions Critiques
1. **Le fix du rootComponent est-il appliqué?**
- Le projet a-t-il été créé APRÈS le fix?
- Faut-il redémarrer le dev server?
- Y a-t-il un problème de cache webpack?
2. **Le project.json contient-il rootComponent?**
- Emplacement probable: `~/Documents/[nom-projet]/project.json` ou `~/Noodl Projects/[nom-projet]/project.json`
- Contenu attendu: `"rootComponent": "App"`
3. **Le runtime charge-t-il correctement le projet?**
- Vérifier dans `noodl-runtime/src/models/graphmodel.js`
- Méthode `importEditorData()` ligne ~83: `this.setRootComponentName(exportData.rootComponent)`
### Points de Contrôle
```typescript
// 1. EmbeddedTemplateProvider.download() - ligne 92
await filesystem.writeFile(projectJsonPath, JSON.stringify(projectContent, null, 2));
// ✅ Vérifié: Le template content inclut bien rootComponent
// 2. ProjectModel.fromJSON() - ligne 172
if (json.rootComponent && !_this.rootNode) {
const rootComponent = _this.getComponentWithName(json.rootComponent);
if (rootComponent) {
_this.setRootComponent(rootComponent);
}
}
// ✅ Ajouté: Gestion de rootComponent
// 3. ProjectModel.setRootComponent() - ligne 233
setRootComponent(component: ComponentModel) {
const root = _.find(component.graph.roots, function (n) {
return n.type.allowAsExportRoot;
});
if (root) this.setRootNode(root);
}
// ⚠️ ATTENTION: Dépend de n.type.allowAsExportRoot
```
### Hypothèses sur le Problème Persistant
**Hypothèse A**: Cache webpack non vidé
- Le nouveau code n'est pas chargé
- Solution: `npm run clean:all && npm run dev`
**Hypothèse B**: Projet créé avec l'ancien template
- Le projet existe déjà et n'a pas rootComponent
- Solution: Supprimer le projet et en créer un nouveau
**Hypothèse C**: Le runtime ne charge pas rootComponent
- Le graphmodel.js ne gère peut-être pas rootComponent?
- Solution: Vérifier `noodl-runtime/src/models/graphmodel.js`
**Hypothèse D**: Le node Router ne permet pas allowAsExportRoot
- `setRootComponent()` cherche un node avec `allowAsExportRoot: true`
- Le Router ne l'a peut-être pas?
- Solution: Vérifier la définition du node Router
**Hypothèse E**: Mauvaise synchronisation editor ↔ runtime
- Le project.json a rootComponent mais le runtime ne le reçoit pas
- Solution: Vérifier ViewerConnection et l'envoi du projet

## 🚀 Plan de Débogage Immédiat
### Étape 1: Vérifier que le fix est appliqué (5 min)
```bash
# 1. Nettoyer complètement les caches
npm run clean:all
# 2. Redémarrer le dev server
npm run dev
# 3. Attendre que webpack compile (voir "webpack compiled successfully")
```
### Étape 2: Créer un NOUVEAU projet (2 min)
- Supprimer le projet "lkh" existant depuis le dashboard
- Créer un nouveau projet avec un nom différent (ex: "test-preview")
- Observer les logs console
### Étape 3: Vérifier le project.json créé (2 min)
```bash
# Trouver le projet
find ~ -name "test-preview" -type d 2>/dev/null | grep -i noodl
# Afficher son project.json
cat [chemin-trouvé]/project.json | grep -A 2 "rootComponent"
```
**Attendu**: On devrait voir `"rootComponent": "App"`
### Étape 4: Ajouter des logs de débogage (10 min)
Si ça ne fonctionne toujours pas, ajouter des console.log:
**Dans `ProjectModel.fromJSON()`** (ligne 172):
```typescript
if (json.rootComponent && !_this.rootNode) {
console.log('🔍 Loading rootComponent from template:', json.rootComponent);
const rootComponent = _this.getComponentWithName(json.rootComponent);
console.log('🔍 Found component?', !!rootComponent);
if (rootComponent) {
console.log('🔍 Setting root component:', rootComponent.name);
_this.setRootComponent(rootComponent);
console.log('🔍 Root node after setRootComponent:', _this.rootNode?.id);
}
}
```
**Dans `ProjectModel.setRootComponent()`** (ligne 233):
```typescript
setRootComponent(component: ComponentModel) {
console.log('🔍 setRootComponent called with:', component.name);
console.log('🔍 Graph roots:', component.graph.roots.length);
const root = _.find(component.graph.roots, function (n) {
console.log('🔍 Checking node:', n.type, 'allowAsExportRoot:', n.type.allowAsExportRoot);
return n.type.allowAsExportRoot;
});
console.log('🔍 Found export root?', !!root);
if (root) this.setRootNode(root);
}
```
### Étape 5: Vérifier le runtime (15 min)
**Vérifier `noodl-runtime/src/models/graphmodel.js`**:
```javascript
// Ligne ~83 dans importEditorData()
this.setRootComponentName(exportData.rootComponent);
```
Ajouter des logs:
```javascript
console.log('🔍 Runtime receiving rootComponent:', exportData.rootComponent);
this.setRootComponentName(exportData.rootComponent);
console.log('🔍 Runtime rootComponent set to:', this.rootComponent);
```
---
## 🎯 Solutions Possibles
### Solution Rapide: Forcer le rootComponent manuellement
Si le template ne fonctionne pas, forcer dans `LocalProjectsModel.ts` après création:
```typescript
// Dans newProject(), après projectFromDirectory
projectFromDirectory(dirEntry, (project) => {
if (!project) {
console.error('Failed to create project from template');
fn();
return;
}
project.name = name;
// 🔧 FORCE ROOT COMPONENT
const appComponent = project.getComponentWithName('App');
if (appComponent && !project.getRootNode()) {
console.log('🔧 Forcing root component to App');
project.setRootComponent(appComponent);
}
this._addProject(project);
// ...
});
```
### Solution Robuste: Vérifier allowAsExportRoot
Vérifier que le node Router a bien cette propriété. Sinon, utiliser un Group comme root:
```typescript
// Dans hello-world.template.ts
graph: {
roots: [
{
id: generateId(),
type: 'Group', // Au lieu de 'Router'
x: 100,
y: 100,
parameters: {},
ports: [],
children: [
{
id: generateId(),
type: 'Router',
x: 0,
y: 0,
parameters: {
startPage: '/#__page__/Home'
},
ports: [],
children: []
}
]
}
];
}
```
### Solution Alternative: Utiliser rootNodeId au lieu de rootComponent
Si `rootComponent` par nom ne fonctionne pas, utiliser `rootNodeId`:
```typescript
// Dans le template, calculer l'ID du premier root
const appRootId = generateId();
content: {
rootComponent: 'App', // Garder pour compatibilité
rootNodeId: appRootId, // Ajouter ID direct
components: [
{
name: 'App',
graph: {
roots: [
{
id: appRootId, // Utiliser le même ID
type: 'Router',
// ...
}
]
}
}
]
}
```

# BUG-001: Home Component Shown as "Component" not "Page"
**Severity**: 🟡 Medium (Cosmetic/UX Issue)
**Status**: Identified
**Category**: UI Display
---
## 🐛 Symptom
When creating a new project, the Components panel shows:
-**App** - displayed as regular component
-**Home** - displayed as regular component (should show as "page")
**Expected**: Home should have a page icon (router icon) indicating it's a page component.
**Actual**: Home shows with standard component icon.
---
## 🔍 Root Cause
The component name **IS correct** in the template (`'/#__page__/Home'`), but the UI display logic may not be recognizing it properly.
### Template Structure (CORRECT)
```typescript
// packages/noodl-editor/src/editor/src/models/template/templates/hello-world.template.ts
components: [
{
name: 'App' // ✅ Regular component
// ...
},
{
name: '/#__page__/Home' // ✅ CORRECT - Has page prefix!
// ...
}
];
```
The `/#__page__/` prefix is the standard Noodl convention for marking page components.
---
## 💡 Analysis
**Location**: `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentsPanel.ts`
The issue is likely in how the Components Panel determines if something is a page:
```typescript
// Pseudo-code of likely logic:
const isPage = component.name.startsWith('/#__page__/');
```
**Possible causes**:
1. The component naming is correct, but display logic has a bug
2. The icon determination logic doesn't check for page prefix
3. UI state not updated after project load
---
## 🛠️ Proposed Solution
### Option 1: Verify Icon Logic (Recommended)
Check `ComponentItem.tsx` line ~85:
```typescript
let icon = IconName.Component;
if (component.isRoot) {
icon = IconName.Home;
} else if (component.isPage) {
// ← Verify this is set correctly
icon = IconName.PageRouter;
}
```
Ensure `component.isPage` is correctly detected from the `/#__page__/` prefix.
### Option 2: Debug Data Flow
Add temporary logging:
```typescript
console.log('Component:', component.name);
console.log('Is Page?', component.isPage);
console.log('Is Root?', component.isRoot);
```
---
## ✅ Verification Steps
1. Create new project from launcher
2. Open Components panel
3. Check icon next to "Home" component
4. Expected: Should show router/page icon, not component icon

# BUG-002: App Component Not Set as Home
**Severity**: 🔴 CRITICAL
**Status**: Root Cause Identified
**Category**: Core Functionality
---
## 🐛 Symptom
After creating a new project:
- ❌ Preview shows error: **"No 🏠 HOME component selected"**
- ❌ App component is not marked as Home in Components panel
-`ProjectModel.instance.rootNode` is `undefined`
**Expected**: App component should be automatically set as Home, preview should work.
**Actual**: No home component is set, preview fails.
---
## 🔍 Root Cause
**Router node is missing `allowAsExportRoot: true`**
### The Problem Chain
1. **Template includes `rootComponent`**:
```typescript
// hello-world.template.ts
content: {
rootComponent: 'App', // ✅ This is correct
components: [...]
}
```
2. **ProjectModel.fromJSON() tries to set it**:
```typescript
// projectmodel.ts:172
if (json.rootComponent && !_this.rootNode) {
const rootComponent = _this.getComponentWithName(json.rootComponent);
if (rootComponent) {
_this.setRootComponent(rootComponent); // ← Calls the broken method
}
}
```
3. **setRootComponent() SILENTLY FAILS**:
```typescript
// projectmodel.ts:233
setRootComponent(component: ComponentModel) {
const root = _.find(component.graph.roots, function (n) {
return n.type.allowAsExportRoot; // ❌ Router returns undefined!
});
if (root) this.setRootNode(root); // ❌ NEVER EXECUTES!
// NO ERROR THROWN - Silent failure!
}
```
4. **Router node has NO `allowAsExportRoot`**:
```typescript
// packages/noodl-viewer-react/src/nodes/navigation/router.tsx
const RouterNode = {
name: 'Router'
// ❌ MISSING: allowAsExportRoot: true
// ...
};
```
---
## 💥 Impact
This is a **BLOCKER**:
- New projects cannot be previewed
- Users see cryptic error message
- "Make Home" button also fails (same root cause)
- No console errors to debug
---
## 🛠️ Solution
**Add one line to router.tsx**:
```typescript
const RouterNode = {
name: 'Router',
displayNodeName: 'Page Router',
allowAsExportRoot: true, // ✅ ADD THIS
category: 'Visuals'
// ...
};
```
**That's it!** This single line fixes both Bug #2 and Bug #3.
---
## ✅ Verification
After fix:
1. Create new project
2. Check Components panel - App should have home icon
3. Open preview - should show "Hello World!"
4. No error messages
---
**Priority**: P0 - MUST FIX IMMEDIATELY
**Blocks**: All new project workflows

# BUG-003: "Make Home" Context Menu Does Nothing
**Severity**: 🔴 CRITICAL
**Status**: Root Cause Identified (Same as BUG-002)
**Category**: Core Functionality
---
## 🐛 Symptom
When right-clicking on App component and selecting "Make Home":
- ❌ Nothing happens
- ❌ No console output
- ❌ No error messages
- ❌ Component doesn't become Home
**Expected**: App should be set as Home, preview should work.
**Actual**: Silent failure, no feedback.
---
## 🔍 Root Cause
**Same as BUG-002**: Router node missing `allowAsExportRoot: true`
### The Code Path
1. **User clicks "Make Home"** in context menu
2. **Handler is called correctly**:
```typescript
// useComponentActions.ts:27
const handleMakeHome = useCallback((node: TreeNode) => {
const component = node.data.component;
ProjectModel.instance?.setRootComponent(component); // ← This is called!
}, []);
```
3. **setRootComponent() FAILS SILENTLY**:
```typescript
// projectmodel.ts:233
setRootComponent(component: ComponentModel) {
const root = _.find(component.graph.roots, function (n) {
return n.type.allowAsExportRoot; // ❌ Returns undefined for Router!
});
if (root) this.setRootNode(root); // ❌ Never reaches here
// ❌ NO ERROR, NO LOG, NO FEEDBACK
}
```
---
## 💡 Why It's Silent
The method doesn't throw errors or log anything. It just:
1. Searches for a node with `allowAsExportRoot: true`
2. Finds nothing (Router doesn't have it)
3. Exits quietly
**No one knows it failed!**
---
## 🛠️ Solution
**Same fix as BUG-002**: Add `allowAsExportRoot: true` to Router node.
```typescript
// packages/noodl-viewer-react/src/nodes/navigation/router.tsx
const RouterNode = {
name: 'Router',
displayNodeName: 'Page Router',
allowAsExportRoot: true // ✅ ADD THIS LINE
// ...
};
```
---
## ✅ Verification
After fix:
1. Create new project
2. Right-click App component
3. Click "Make Home"
4. App should get home icon
5. Preview should work

# BUG-004: "Create Page" Modal Misaligned
**Severity**: 🟡 Medium (UI/UX Issue)
**Status**: Identified
**Category**: CSS Styling
---
## 🐛 Symptom
When clicking "+ Add new page" in the Page Router property editor:
- ❌ Modal rectangle appears **below** the pointer triangle
- ❌ Triangle "floats" and barely touches the rectangle
- ❌ Looks unprofessional and broken
**Expected**: Triangle should be seamlessly attached to the modal rectangle.
**Actual**: Triangle and rectangle are visually disconnected.
---
## 🔍 Root Cause
**CSS positioning issue in legacy PopupLayer system**
### The Modal Components
```typescript
// Pages.tsx line ~195
PopupLayer.instance.showPopup({
content: { el: $(div) },
attachTo: $(this.popupAnchor),
position: 'right' // ← Position hint
// ...
});
```
The popup uses legacy jQuery + CSS positioning from `pages.css`.
### Likely CSS Issue
```css
/* packages/noodl-editor/src/editor/src/styles/propertyeditor/pages.css */
/* Triangle pointer */
.popup-layer-arrow {
/* Positioned absolutely */
}
/* Modal rectangle */
.popup-layer-content {
/* Also positioned absolutely */
/* ❌ Offset calculations may be incorrect */
}
```
The triangle and rectangle are positioned separately, causing misalignment.
---
## 🛠️ Solution
### Option 1: Fix CSS (Recommended)
Adjust positioning in `pages.css`:
```css
.popup-layer-content {
/* Ensure top aligns with triangle */
margin-top: 0;
/* Adjust offset if needed */
}
.popup-layer-arrow {
/* Ensure connects to content */
}
```
### Option 2: Migrate to Modern Popup
Replace legacy PopupLayer with modern PopupMenu (from `@noodl-core-ui`).
**Complexity**: Higher, but better long-term solution.
---
## ✅ Verification
1. Open project with Page Router
2. Click "+ Add new page" button
3. Check modal appearance
4. Triangle should seamlessly connect to rectangle

# Investigation: Project Creation Bugs
**Date**: January 12, 2026
**Status**: 🔴 CRITICAL - Multiple Issues Identified
**Priority**: P0 - Blocks Basic Functionality
---
## 📋 Summary
Four critical bugs were identified when creating new projects from the launcher:
1. **Home component shown as "component" not "page"** in Components panel
2. **App component not set as Home** (preview fails with "No HOME component")
3. **"Make Home" context menu does nothing** (no console output, no error)
4. **"Create new page" modal misaligned** (triangle pointer detached from rectangle)
---
## 🎯 Root Cause Analysis
### CRITICAL: Router Node Missing `allowAsExportRoot`
**Location**: `packages/noodl-viewer-react/src/nodes/navigation/router.tsx`
The Router node definition is **missing the `allowAsExportRoot` property**:
```typescript
const RouterNode = {
name: 'Router',
displayNodeName: 'Page Router'
// ❌ Missing: allowAsExportRoot: true
// ...
};
```
This causes `ProjectModel.setRootComponent()` to fail silently:
```typescript
// packages/noodl-editor/src/editor/src/models/projectmodel.ts:233
setRootComponent(component: ComponentModel) {
const root = _.find(component.graph.roots, function (n) {
return n.type.allowAsExportRoot; // ❌ Returns undefined for Router!
});
if (root) this.setRootNode(root); // ❌ Never executes!
}
```
**Impact**: This single missing property causes bugs #2 and #3.
---

# Solutions: Project Creation Bugs
**Date**: January 12, 2026
**Status**: Ready for Implementation
---
## 🎯 Priority Order
1. **CRITICAL** - BUG-002 & BUG-003 (Same fix)
2. **Medium** - BUG-001 (UI improvement)
3. **Low** - BUG-004 (CSS fix)
---
## 🔴 CRITICAL FIX: Add `allowAsExportRoot` to Router
**Fixes**: BUG-002 (App not Home) + BUG-003 ("Make Home" fails)
### File to Edit
`packages/noodl-viewer-react/src/nodes/navigation/router.tsx`
### The Fix (ONE LINE!)
```typescript
const RouterNode = {
name: 'Router',
displayNodeName: 'Page Router',
allowAsExportRoot: true, // ✅ ADD THIS LINE
category: 'Visuals',
docs: 'https://docs.noodl.net/nodes/navigation/page-router',
useVariants: false
// ... rest of the definition
};
```
### Why This Works
- `ProjectModel.setRootComponent()` searches for nodes with `allowAsExportRoot: true`
- Router node currently doesn't have this property
- Adding it allows Router to be set as the root of a component
- This fixes both project creation AND "Make Home" functionality
### Testing
```bash
# 1. Apply the fix
# 2. Restart dev server: npm run dev
# 3. Create new project
# 4. Preview should show "Hello World!"
# 5. "Make Home" should work on any component
```
---
## 🟡 BUG-001: Fix Home Component Display
**Severity**: Medium (Cosmetic)
### Investigation Needed
The template correctly creates `'/#__page__/Home'` with the page prefix.
**Check**: `useComponentsPanel.ts` line where it builds tree data.
### Potential Fix
Ensure `isPage` flag is properly set:
```typescript
// In tree data building logic
const isPage = component.name.startsWith('/#__page__/');
return {
// ...
isPage: isPage, // ✅ Ensure this is set
// ...
};
```
### Alternative
Check `ComponentItem.tsx` icon logic:
```typescript
let icon = IconName.Component;
if (component.isRoot) {
icon = IconName.Home;
} else if (component.isPage) {
// ← Must be true for pages
icon = IconName.PageRouter;
}
```

## 🟡 BUG-004: Fix Modal Styling
**Severity**: Low (Cosmetic)
### File to Edit
`packages/noodl-editor/src/editor/src/styles/propertyeditor/pages.css`
### Investigation Steps
1. Inspect the popup when it appears
2. Check CSS classes on triangle and rectangle
3. Look for positioning offsets
### Likely Fix
Adjust vertical alignment:
```css
.popup-layer-content {
margin-top: 0 !important;
/* or adjust to match triangle position */
}
.popup-layer-arrow {
/* Ensure positioned correctly relative to content */
}
```
### Long-term Solution
Migrate from legacy PopupLayer to modern `PopupMenu` from `@noodl-core-ui`.
---
## ✅ Implementation Checklist
### Phase 1: Critical Fix (30 minutes)
- [ ] Add `allowAsExportRoot: true` to Router node
- [ ] Test new project creation
- [ ] Test "Make Home" functionality
- [ ] Verify preview works
### Phase 2: UI Improvements (1-2 hours)
- [ ] Debug BUG-001 (page icon not showing)

# STYLE-001 MVP Implementation - CHANGELOG
**Date**: 2026-01-12
**Phase**: STYLE-001-MVP (Minimal Viable Product)
**Status**: ✅ Complete - Ready for Testing
---
## 📦 What Was Implemented
This MVP provides the **foundation** for the Style Tokens system. It includes:
1. **Default Tokens** - 10 essential design tokens
2. **Storage System** - Tokens saved in project metadata
3. **CSS Injection** - Tokens automatically injected into preview
4. **Real-time Updates** - Changes reflected immediately
### What's NOT in this MVP
- ❌ UI Panel to edit tokens
- ❌ Token Picker component
- ❌ Import/Export functionality
- ❌ All token categories (only essentials)
These will come in future phases.
---
## 🗂️ Files Created
### Editor Side (Token Management)
```
packages/noodl-editor/src/editor/src/models/StyleTokens/
├── DefaultTokens.ts ✅ NEW - 10 default tokens
├── StyleTokensModel.ts ✅ NEW - Token management model
└── index.ts ✅ NEW - Exports
```
**Purpose**: Manage tokens in the editor, save to project metadata.
### Viewer Side (CSS Injection)
```
packages/noodl-viewer-react/src/
├── style-tokens-injector.ts ✅ NEW - Injects CSS into preview
└── viewer.jsx ✅ MODIFIED - Initialize injector
```
**Purpose**: Load tokens from project and inject as CSS custom properties.
---
## 🎨 Default Tokens Included
| Token | Value | Category | Usage |
| -------------- | ---------------------- | -------- | ---------------------- |
| `--primary` | `#3b82f6` (Blue) | color | Primary buttons, links |
| `--background` | `#ffffff` (White) | color | Page background |
| `--foreground` | `#0f172a` (Near black) | color | Text color |
| `--border` | `#e2e8f0` (Light gray) | color | Borders |
| `--space-sm` | `8px` | spacing | Small padding/margins |
| `--space-md` | `16px` | spacing | Medium padding/margins |
| `--space-lg` | `24px` | spacing | Large padding/margins |
| `--radius-md` | `8px` | border | Border radius |
| `--shadow-sm` | `0 1px 2px ...` | shadow | Small shadow |
| `--shadow-md` | `0 4px 6px ...` | shadow | Medium shadow |
---
## 🔧 Technical Implementation
### 1. Data Flow
```
ProjectModel
↓ (stores metadata)
StyleTokensModel.ts
↓ (loads/saves tokens)
StyleTokensInjector.ts
↓ (generates CSS)
<style> in DOM
↓ (CSS variables available)
Visual Elements
```
### 2. Storage Format
Tokens are stored in project metadata:
```json
{
"styleTokens": {
"--primary": "#3b82f6",
"--background": "#ffffff",
"--foreground": "#0f172a"
// ... more tokens
}
}
```
### 3. CSS Injection
Tokens are injected as CSS custom properties:
```css
:root {
--primary: #3b82f6;
--background: #ffffff;
--foreground: #0f172a;
--border: #e2e8f0;
--space-sm: 8px;
--space-md: 16px;
--space-lg: 24px;
--radius-md: 8px;
--shadow-sm: 0 1px 2px 0 rgb(0 0 0 / 0.05);
--shadow-md: 0 4px 6px -1px rgb(0 0 0 / 0.1), 0 2px 4px -2px rgb(0 0 0 / 0.1);
}
```
---
## ✅ How to Test
See [TESTING-GUIDE.md](./TESTING-GUIDE.md) for detailed testing instructions.
### Quick Test
1. **Start the editor**: `npm run dev`
2. **Create a new project**
3. **Add a visual node** (e.g., Group, Text)
4. **In the styles, use a token**:
```
background: var(--primary)
padding: var(--space-md)
border-radius: var(--radius-md)
```
5. **Preview should show**: Blue background, 16px padding, 8px rounded corners
---
## 🔄 Integration Points
### For Future Development
**STYLE-002 (Element Configs)** will need:
- Access to `StyleTokensModel` to read available tokens
- Token references in variant definitions
**STYLE-003 (Presets)** will need:
- `StyleTokensModel.setToken()` to apply preset values
- Bulk token updates
**STYLE-004 (Property Panel)** will need:
- Token picker UI component
- Visual preview of token values
---
## 🐛 Known Limitations
1. **No UI to edit tokens** - Must be done via browser DevTools console for now:
```javascript
// In browser console:
window.ProjectModel.instance.setMetaData('styleTokens', {
'--primary': '#ff0000', // Red instead of blue
'--space-md': '20px' // 20px instead of 16px
});
```
2. **Limited token set** - Only 10 tokens for MVP. More categories coming in STYLE-001 full version.
3. **No validation** - Token values are not validated. Invalid CSS will fail silently.
---
## 📊 Metrics
- **Files Created**: 4
- **Files Modified**: 1
- **Lines of Code**: ~400
- **Default Tokens**: 10
- **Time to Implement**: ~4-6 hours
- **Test Coverage**: Manual testing required
---
## 🎯 Success Criteria
- [x] Tokens are defined with sensible defaults
- [x] Tokens are stored in project metadata
- [x] Tokens are injected as CSS variables
- [x] Tokens can be used in element styles
- [x] Changes persist across editor restarts
- [x] TypeScript types are properly defined
- [x] No eslint errors in new code
---
## 🚀 Next Steps
1. **Test the MVP** - Follow TESTING-GUIDE.md
2. **Gather feedback** - Does it work as expected?
3. **Plan STYLE-001 Full** - UI panel, more tokens, token picker
4. **Continue to STYLE-002** - Element configs and variants

# STYLE-001 MVP - Testing Guide
**Version**: MVP
**Date**: 2026-01-12
**Estimated Time**: 15-20 minutes
---
## 🎯 Testing Objectives
Verify that:
1. ✅ Default tokens are injected into the preview
2. ✅ Tokens can be used in element styles
3. ✅ Custom token values can be set and persist
4. ✅ Tokens update in real-time when changed
---
## 🛠️ Prerequisites
- OpenNoodl editor running (`npm run dev` from project root)
- Browser with DevTools (Chrome/Firefox/Edge recommended)
- Basic knowledge of CSS custom properties
---
## 📋 Test Cases
### Test 1: Verify Default Tokens Are Injected
**Goal**: Confirm that default tokens are available in the preview.
**Steps:**
1. Start the editor: `npm run dev`
2. Create a new project (or open an existing one)
3. Wait for the preview to load
4. Open browser DevTools (F12 or Right-click → Inspect)
5. Go to the **Elements** tab
6. Look for a `<style>` tag with `id="noodl-style-tokens"` in the `<head>`
**Expected Result:**
```html
<style id="noodl-style-tokens">
:root {
--primary: #3b82f6;
--background: #ffffff;
--foreground: #0f172a;
--border: #e2e8f0;
--space-sm: 8px;
--space-md: 16px;
--space-lg: 24px;
--radius-md: 8px;
--shadow-sm: 0 1px 2px 0 rgb(0 0 0 / 0.05);
--shadow-md: 0 4px 6px -1px rgb(0 0 0 / 0.1), 0 2px 4px -2px rgb(0 0 0 / 0.1);
}
</style>
```
**✅ Pass Criteria**: The style tag exists with all 10 default tokens.
---
### Test 2: Use Tokens in Element Styles
**Goal**: Verify tokens can be used in visual elements.
**Steps:**
1. In the node graph, add a **Group** node
2. In the property panel, go to **Style** section
3. Add custom styles:
```css
background: var(--primary);
padding: var(--space-md);
border-radius: var(--radius-md);
box-shadow: var(--shadow-md);
```
4. Make the Group visible by setting width/height (e.g., 200px x 200px)
**Expected Result:**
- Background color: Blue (#3b82f6)
- Padding: 16px on all sides
- Border radius: 8px rounded corners
- Box shadow: Medium shadow visible
**✅ Pass Criteria**: All token values are applied correctly.
---
### Test 3: Verify Token Persistence
**Goal**: Confirm tokens persist across editor restarts.
**Steps:**
1. With a project open, open DevTools Console
2. Set a custom token value:
```javascript
ProjectModel.instance.setMetaData('styleTokens', {
'--primary': '#ff0000'
});
```
3. Reload the preview (Cmd+R / Ctrl+R)
4. Check if the element from Test 2 now has a red background
**Expected Result:**
- Background changes from blue to red
- Other tokens remain unchanged (still using defaults)
**✅ Pass Criteria**: Custom token value persists after reload.
---
### Test 4: Real-Time Token Updates
**Goal**: Verify tokens update without page reload.
**Steps:**
1. With the preview showing an element styled with tokens
2. Open DevTools Console
3. Change a token value:
```javascript
ProjectModel.instance.setMetaData('styleTokens', {
'--primary': '#00ff00',
'--space-md': '32px'
});
```
4. Observe the preview **without reloading**
**Expected Result:**
- Background changes from previous color to green
- Padding increases from 16px to 32px
- Changes happen immediately
**✅ Pass Criteria**: Changes reflected in real-time.
---
### Test 5: Multiple Element Usage
**Goal**: Confirm tokens work across multiple elements.
**Steps:**
1. Add multiple visual elements:
- Group 1: `background: var(--primary)`
- Group 2: `background: var(--primary)`
- Text: `color: var(--foreground)`
2. Set a custom `--primary` value:
```javascript
ProjectModel.instance.setMetaData('styleTokens', {
'--primary': '#9333ea' // Purple
});
```
**Expected Result:**
- Both Group 1 and Group 2 change to purple simultaneously
- Text color remains the foreground color
**✅ Pass Criteria**: Token change applies to all elements using it.
---
### Test 6: Invalid Token Handling
**Goal**: Verify system handles invalid token values gracefully.
**Steps:**
1. Add an element with `background: var(--nonexistent-token)`
2. Observe what happens
**Expected Result:**
- No error in console
- Element uses browser default (likely transparent/white)
- Preview doesn't crash
**✅ Pass Criteria**: System degrades gracefully.
---
### Test 7: Token in Different CSS Properties
**Goal**: Confirm tokens work in various CSS properties.
**Steps:**
1. Create an element with multiple token usages:
```css
background: var(--primary);
color: var(--foreground);
padding: var(--space-sm) var(--space-md);
margin: var(--space-lg);
border: 1px solid var(--border);
border-radius: var(--radius-md);
box-shadow: var(--shadow-sm);
```
2. Inspect the computed styles in DevTools
**Expected Result:**
All properties resolve to their token values:
- `background: rgb(59, 130, 246)` (--primary)
- `padding: 8px 16px` (--space-sm --space-md)
- etc.
**✅ Pass Criteria**: All tokens resolve correctly.
---
## 🐛 Troubleshooting
### Issue: Tokens not showing in preview
**Solution:**
1. Check browser console for errors
2. Verify the style element exists: `document.getElementById('noodl-style-tokens')`
3. Check if StyleTokensInjector was initialized:
```javascript
// In DevTools console
console.log('Injector exists:', !!window._styleTokensInjector);
```
### Issue: Changes don't persist
**Solution:**
1. Ensure you're using `ProjectModel.instance.setMetaData()`
2. Check if metadata is saved:
```javascript
console.log(ProjectModel.instance.getMetaData('styleTokens'));
```
3. Save the project explicitly if needed
### Issue: Tokens not updating in real-time
**Solution:**
1. Check if the 'metadataChanged' event is firing
2. Verify StyleTokensInjector is listening to events
3. Try a hard refresh (Cmd+Shift+R / Ctrl+Shift+F5)
