🔄 IN PROGRESS (Phase 2 - Template Rendering)

4. Template Visual Rendering 🚧 NEXT STEP

Goal: Actually render CSS Grid layouts from template manifests

What's Needed:

  1. Create TemplateRendererComponent that:
    • Reads manifest.metadata.platforms.web.gridTemplate
    • Applies CSS Grid to container
    • Renders region containers
  2. Add templateId field to CanvasSection model
  3. Update canvas-section.component.ts to detect template sections
  4. Render TemplateRendererComponent when section.templateId exists

Example Flow:

// User drops "Split Sidebar" template on ROOT
// Canvas creates section with:
{
  id: 'root',
  templateId: 'template-split-sidebar', // NEW FIELD
  children: [] // Regions will be created by renderer
}

// TemplateRendererComponent reads manifest:
{
  gridTemplate: '"sidebar main" 1fr / 300px 1fr',
  regions: [
    { name: 'sidebar', width: '300px' },
    { name: 'main', flex: true }
  ]
}

// Applies CSS Grid:
<div style="display: grid; grid-template: '...'">
  <div class="region" data-region="sidebar">
    <!-- Drop zone for modules -->
  </div>
  <div class="region" data-region="main">
    <!-- Drop zone for modules -->
  </div>
</div>

Status: Not started yet (30-60 min of work)

5. Region Container Component 🚧 NEXT STEP

Goal: Create drop zones for template regions

What's Needed:

// Component: RegionContainerComponent
@Component({
  selector: 'lib-region-container',
  standalone: true,
  // ...
})
export class RegionContainerComponent {
  region = input.required<TemplateRegion>();
  modules = input<ModuleInstance[]>([]);
  
  // Drop handling
  onModuleDrop(module: ModuleManifest) {
    this.moduleDrop.emit({ region: this.region(), module });
  }
  
  // Render dropped modules
  renderModules() {
    return this.modules().map(m => `<div>${m.name}</div>`);
  }
}

User Experience:

Status: Not started yet (30-45 min of work)

📊 Current Capabilities (What Works TODAY)

✅ Available NOW (No Template Rendering):

  1. Build platforms section-by-section:

    • Add sections manually
    • Drag modules into sections
    • Unlimited nesting of sections
    • Flexbox layout (row/column)

  2. Visual editing:

    • Resizable panels (working!)
    • Zoom in/out
    • Responsive preview (mobile/tablet/desktop)
    • Undo/Redo (Ctrl+Z/Ctrl+Y)

  3. Module system:

    • Enhanced palette with categories
    • Drag-drop modules/widgets
    • Visual feedback on drop
    • Module placeholders render

  4. Persistence:

    • Auto-save to IndexedDB (debounced 500ms)
    • Flash persistence
    • Survives page reload
    • Panel sizes persist

🔄 Coming Soon (With Template Rendering):

  1. One-click layouts:

    • Drag "Split Sidebar" → Instant 2-column layout
    • Drag "Header/Content/Footer" → Instant page layout
    • Pre-configured CSS Grid

  2. Region-based building:

    • Drop modules directly into template regions
    • Visual distinction between regions
    • Region-specific constraints

  3. Professional templates:

    • 4 working templates ready:
      • Split Sidebar (300px + flex)
      • Two Column Equal (50/50 split)
      • Three Column Equal (33/33/33)
      • Header/Content/Footer (auto/flex/auto)

🎯 Immediate Next Steps (1-2 hours of work)

Priority 1: Template Rendering (60 min)

  1. Add templateId? field to CanvasSection type
  2. Create TemplateRendererComponent:
    • Read manifest from ModuleRegistryService
    • Apply CSS Grid from metadata.platforms.web
    • Render region containers
  3. Update canvas-section.component.html:
    • Detect section().templateId
    • Render <lib-template-renderer> instead of regular content
  4. Test: Drop template → See CSS Grid layout

Priority 2: Region Containers (45 min)

  1. Create RegionContainerComponent:
    • Input: TemplateRegion data
    • Drop zone for modules
    • Render dropped modules
  2. Integrate into TemplateRendererComponent
  3. Update canvas-builder to handle region drops:
    • Store modules in region.modules[]
  4. Test: Drop module into region → Persists correctly

Priority 3: End-to-End Testing (30 min)

  1. Workflow test:
    • Open canvas builder
    • Drag "Split Sidebar" template to ROOT
    • Drop "Sidebar Navigation" into sidebar region
    • Drop "Top Navigation" into main region
    • Reload page → Verify persistence
  2. Export test:
    • Copy JSON from viewer
    • Verify structure matches expectations
  3. Multi-template test:
    • Create complex layout with nested templates
    • Verify rendering and persistence

🚀 Deployment Readiness

✅ Production-Ready Components (Can deploy NOW):

    • Clean, categorized UI
    • Professional styling
    • Drag-drop works perfectly

  2. Resizable Panels ✅

    • Smooth UX
    • Persists correctly
    • No bugs

  3. Basic Canvas Building ✅

    • Section-based building works
    • Module drop works
    • Persistence works

🔄 Needs Template Rendering (Before Full Launch):

  1. Template-Based Building 🚧

    • One-click layouts
    • Region containers
    • CSS Grid rendering

  2. Professional Workflow 🚧

    • Drag template → Instant layout
    • Drop modules into regions
    • Export complete platform

📝 Technical Debt (Future Improvements)

Low Priority (Post-Launch):

Known Limitations:

🎓 What the User Can Do RIGHT NOW

✅ Available Workflows:

Workflow 1: Traditional Section-Based Building

  1. Open universe builder
  2. Click "Add Section" to create sections manually
  3. Drag modules from palette into sections
  4. Configure in right panel
  5. Export JSON → Deploy

Workflow 2: Module-First Building

  1. Open universe builder
  2. Drag modules directly onto canvas
  3. Builder auto-creates sections
  4. Organize with move up/down/in/out buttons
  5. Export JSON → Deploy

Workflow 3: Explore Enhanced Palette

  1. Open "Templates" tab → See 4 layout templates
  2. Open "Modules" tab → See categorized modules (Navigation, Content, Other)
  3. Open "Widgets" tab → See available widgets
  4. Resize left sidebar to see more/less
  5. Drag any item to canvas (works!)

🏁 Summary

What's Done:
