TASK-007I: Data Browser Panel - COMPLETE

Summary

Implemented a full-featured data browser panel for viewing and editing records in local backend SQLite tables, providing a spreadsheet-like interface with inline editing, search, pagination, and CRUD operations.

Status: ✅ Complete

Date: 2026-01-15

---

What Was Implemented

1. Backend IPC Handlers (BackendManager.js)

Added four new IPC handlers for data operations:

• backend:queryRecords - Query records with pagination, sorting, search filters
• backend:createRecord - Create a new record in a table
• backend:saveRecord - Update an existing record (inline edit)
• backend:deleteRecord - Delete a single record

These handlers wrap the existing LocalSQLAdapter CRUD methods (query, create, save, delete) and expose them to the renderer process.

2. DataBrowser Component (panels/databrowser/)

Created a complete data browser panel with the following components:

DataBrowser.tsx (Main Component)

• Table selector dropdown
• Search input with cross-field text search
• Pagination with page navigation (50 records per page)
• Bulk selection and delete operations
• CSV export functionality
• Loading states and error handling
• New record modal trigger

DataGrid.tsx (Spreadsheet View)

• Column headers with type badges (String, Number, Boolean, Date, Object, Array)
• System columns (objectId, createdAt, updatedAt) displayed as read-only
• Inline editing - click any editable cell to edit
• Row selection with checkbox
• Select all/none toggle
• Delete action per row
• Scrollable with sticky header

CellEditor.tsx (Inline Editor)

• Type-aware input controls:
  • String: Text input
  • Number: Number input with step="any"
  • Boolean: Checkbox with immediate save
  • Date: datetime-local input
  • Object/Array: Multi-line JSON editor with Save/Cancel buttons
• Auto-focus and select on mount
• Enter to save, Escape to cancel (for simple types)
• Validation for numbers and JSON parsing
• Error display for invalid input

NewRecordModal.tsx (Create Record Form)

• Form fields generated from column schema
• Type-aware input controls for each field type
• Required field validation
• Default values based on column defaults or type defaults
• Success callback to refresh data grid

3. Styling

All components use theme CSS variables per UI-STYLING-GUIDE.md:

• --theme-color-bg-* for backgrounds
• --theme-color-fg-* for text
• --theme-color-border-* for borders
• --theme-color-primary* for accents
• --theme-color-success/danger/notice for status colors

4. Integration

Added "Data" button to LocalBackendCard (visible when backend is running):

• Opens DataBrowser in a full-screen portal overlay
• Same pattern as Schema panel

How To Use

1. Start a local backend from the Backend Services panel
2. Click the "Data" button on the running backend card
3. Select a table from the dropdown (auto-selects first table if available)
4. Browse records with pagination
5. Click any editable cell to edit inline
6. Use "+ New Record" to add records
7. Use checkboxes for bulk selection and delete
8. Use "Export CSV" to download current view

Technical Notes

Query API

The query API supports:

{
  collection: string,    // Table name
  limit: number,         // Max records (default 50)
  skip: number,          // Pagination offset
  where: object,         // Filter conditions ($or, contains, etc.)
  sort: string[],        // Sort order (e.g., ['-createdAt'])
  count: boolean         // Return total count for pagination
}

Search Implementation

Search uses $or with contains operator across all String columns and objectId. The LocalSQLAdapter converts this to SQLite LIKE queries.

Type Handling

• System fields (objectId, createdAt, updatedAt) are always read-only
• Boolean cells save immediately on checkbox toggle
• Object/Array cells require explicit Save button due to JSON editing
• Dates are stored as ISO8601 strings

Future Improvements (Not in scope)

• Column sorting by clicking headers
• Filter by specific field values
• Relation/Pointer field expansion
• Inline record duplication
• Undo for delete operations
• Import CSV/JSON
