Performance Improvements

Virtualized Data Tables (#80)

Large query results no longer cause typing lag in the Monaco editor. This release introduces TanStack Virtual row virtualization for datasets with more than 50 rows.

Key Improvements:

• Reduced DOM Nodes: From ~15,000 to ~1,000 for 500-row datasets
• Eliminated Typing Delay: Previously 5+ seconds of lag due to React reconciliation overhead
• Header/Row Width Sync: ResizeObserver keeps virtualized rows aligned with header columns
• Full Query Results: Multi-statement queries now show all returned rows with client-side pagination instead of being incorrectly limited to page size

Accessibility:

• Added role="rowgroup" and aria-rowcount to virtualized container
• Added role="row" and aria-rowindex to each virtualized row
• Added role="cell" to each virtualized cell
• Screen readers can now navigate virtualized tables correctly

New Features

Schema Focus for Supabase Users (#84)

If you work with Supabase or databases with many default schemas, you can now focus on a single schema in the Schema Explorer. This filters out all other schemas, making it easier to navigate your actual tables.

Multiline Text Editor (#84)

Long text columns now get proper editing support:

• Auto-Opens: Automatically opens for content longer than 100 characters or containing newlines
• Expand Button: Click to open the multiline editor for any text column
• Full Content View: No more truncated edits for JSON blobs or long descriptions

Redesigned Add Widget Dialog (#84)

The widget creation experience has been streamlined from a multi-step wizard to a single-page form:

• Faster Configuration: All options visible at once
• Live Data Preview: See first 5 rows of query results while configuring
• SQL Autocompletion: Monaco editor with schema-aware suggestions
• Compact UI: Segmented controls, better spacing, and improved layout

Edit Widget Dialog (#84)

New dedicated dialog for editing existing widgets with all configuration options in a single view. Previously, the Configure menu item wasn't wired up correctly—now it works.

---

Bug Fixes

Fixed Enum Data Type Handling (#84)

Enum columns now work correctly in edit mode. Added enumValues to ColumnInfo so dropdown options populate properly.

Fixed Duplicate LIMIT Clause (#84)

Widget data preview no longer fails with duplicate LIMIT clauses when previewing queries.

Fixed Keyboard Shortcuts in Dialogs (#84)

Keyboard shortcuts no longer intercept input when typing in dialog fields.

Fixed Result Switching in Table Preview (#80)

Multi-statement query results now switch correctly between tabs by using the active result's columns.

New Features

Dashboard Widgets (#72, #75)

Build custom dashboards with live SQL-powered widgets. This is a major new feature that brings data visualization directly into data-peek.

Widget Types:

• KPI Widgets: Display single metrics with number, currency, percent, or duration formatting
• Chart Widgets: Visualize data with bar, line, area, or pie charts
• Table Widgets: Show query results in a compact table format

Dashboard Features:

• Drag-and-Drop Grid Layout: Arrange widgets freely using react-grid-layout
• Auto-Refresh: Configure dashboards to refresh on a schedule (every minute, 5 minutes, 15 minutes, or custom intervals)
• AI Widget Suggestions: Get intelligent widget recommendations based on your schema
• Import/Export: Share dashboards between instances or team members
• Keyboard Shortcuts: r to refresh, e to toggle edit mode, n/a to add widget
• Demo Queries: Included SQL examples for building SaaS metrics dashboards

Data Sources:

• Use saved queries or write inline SQL
• Each widget executes its own query against the connected database
• Results cached with configurable refresh intervals

Query Scheduling with Cron Support (#72)

Schedule queries to run automatically in the background using node-cron for reliable execution.

Schedule Options:

• Presets: Every minute, every 5 minutes, every 15 minutes, hourly, daily, weekly
• Custom Cron: Full cron expression support for complex schedules

Features:

• Desktop Notifications: Get notified when scheduled queries complete or fail
• Run History: View execution history with timing and status
• Pause/Resume: Temporarily pause scheduled queries without deleting them
• Connection-Aware: Queries run against their configured database connection
• Error Tracking: Failed runs are logged with error details

Improvements

Web App Blog with MDX (#70)

The data-peek website now includes a blog section with MDX support for rich content and code examples.

Dashboard Auto-Refresh Reliability

• Multi-window event emission ensures all windows receive refresh updates
• Atomic scheduled query storage using mutex to prevent race conditions
• Error handling improvements for widget execution failures

Bug Fixes

Query Preview Trailing Semicolons

Fixed an issue where trailing semicolons in saved queries would cause LIMIT clause addition to fail. The preview query builder now properly strips semicolons before appending LIMIT.

Dashboard Deletion Cleanup

Fixed memory leaks where auto-refresh jobs would continue running after a dashboard was deleted.

Widget Import ID Generation

Fixed an issue where imported dashboards would have missing widget IDs, causing rendering failures.

React Grid Layout v2 Compatibility

Added local GridLayoutItem type definition to fix TypeScript compatibility with react-grid-layout v2.
