# TASK-007D: Launcher Integration

## Overview

Add backend management UI to the Nodegex launcher, enabling users to create, manage, and monitor local backends independently of projects.

**Parent Task:** TASK-007 (Integrated Local Backend)
**Phase:** D (Launcher Integration)
**Effort:** 8-10 hours
**Priority:** MEDIUM
**Depends On:** TASK-007B (Backend Server)

---

## Objectives

1. Add backend management section to launcher
2. Create backend list with status indicators
3. Implement create/delete backend dialogs
4. Add start/stop controls for backends
5. Implement project-backend association UI
6. Create simple data administration panel

### Step 4: Backend Selector for Projects (2 hours)

### Step 6: Integrate into Launcher (1 hour)

**File:** `packages/noodl-editor/src/editor/src/views/Launcher/Launcher.tsx` (modifications)

```tsx
// Add import
import { BackendList } from './BackendManager/BackendList';

// In the Launcher component, add backends section alongside projects:

return (
  <div className={styles.launcher}>
    <div className={styles.content}>
      {/* Existing projects section */}
      <div className={styles.section}>
        <ProjectList 
          projects={projects}
          onOpen={handleOpenProject}
          // ... other props
        />
      </div>

      {/* New backends section */}
      <div className={styles.section}>
        <BackendList />
      </div>
    </div>
  </div>
);
```

## Testing Checklist

### Backend List
- [ ] List loads on launcher open
- [ ] Status indicators show correctly
- [ ] Auto-refresh works
- [ ] Empty state displays correctly

### Backend Card
- [ ] Start button works
- [ ] Stop button works
- [ ] Delete button shows confirmation
- [ ] Admin panel opens
- [ ] Export dialog opens

### Create Dialog
- [ ] Validation works
- [ ] Creates backend successfully
- [ ] Error handling works
- [ ] Dialog closes on success

### Backend Selector
- [ ] Shows in project cards
- [ ] Lists available backends
- [ ] Selection persists
- [ ] Create new option works

### Admin Panel
- [ ] Tables list loads
- [ ] Record viewing works
- [ ] Handles empty tables
- [ ] Handles large datasets

---

## Success Criteria

1. Users can manage backends without opening any project
2. Clear visual indication of backend status
3. Project-backend association is intuitive
4. Basic data exploration is possible
5. All actions have loading/error states

## Dependencies

**Internal:**
- TASK-007B (Backend Server + IPC handlers)

**Blocks:**
- None (UI layer)
