Simplify console list page: design mode toggle + modernized metadata inspector by Copilot · Pull Request #444 · objectstack-ai/objectui

Copilot · 2026-02-11T07:13:31Z

The console list page had too many visible buttons and the metadata inspector panel was always visible, consuming 30% of screen width. Simplified by introducing a design mode toggle and modernizing the metadata inspector following Linear/Vercel patterns.

Changes

Design Mode Separation (NEW)

Runtime Mode (Default): Clean interface for end users
- Only "New" button + design tools menu visible
- Design tools (Metadata, Edit View, Add View) hidden in dropdown
- No metadata panel visible
- ~40% reduction in header complexity
Design Mode: Developer/designer tools accessible via menu
- "Enter Design Mode" menu item
- Wrench icon indicates active state
- Unlocks: Metadata Inspector, Edit View, Add View
- Metadata panel only shows when in design mode

Metadata Inspector Improvements

Default state: Closed (maximizes content space)
Width: w-100 (25rem) → w-80 (20rem)
Sections: Collapsible accordion with first section expanded by default
Copy: Clipboard API with visual feedback (Copy icon → Check icon, 2s timeout)

Visual Design

// Before: Heavy, always-on debug panel
<div className="w-100 border-l bg-muted/30 shadow-xl">
  <pre className="bg-slate-950 text-slate-50">...</pre>
</div>

// After: Light, collapsible inspector (design mode only)
<div className="w-80 border-l bg-background transition-all">
  <div className="border border-border/50 bg-muted/5">
    <pre className="text-[11px] text-foreground/90">...</pre>
  </div>
</div>

Implementation

ObjectView: Added designMode state (default: false), replaced header buttons with DropdownMenu
MetadataPanel: State management for expandedSections and copiedIndex, conditional rendering based on design mode
Fixed: Button nesting HTML validation error
Typography: Improved hierarchy (text-xs font-semibold, text-[11px] leading-relaxed)

Screenshots

Before: Too many buttons, panel always visible

After (Runtime Mode - Default): Clean, focused interface

Design Tools Menu: Progressive disclosure

Design Mode Active: Developer tools unlocked

@copilot 我的意思是整个列表页的区域太复杂，而且是否应该区分设计模式和实际运行模式。

Understood! I've addressed the overall complexity issue by adding a Design Mode toggle that separates runtime mode (for end users) from design mode (for developers/designers).

Changes made (commit 430780e):

Simplified header - Removed always-visible design tools (Metadata, Edit View, Add View buttons)
Runtime mode (default) - Clean interface with just "New" button + design tools menu
Design mode - Accessed via menu, shows Wrench icon when active, unlocks:
- Metadata Inspector
- Edit View
- Add View

Before: Too many buttons cluttering the header
After (Runtime): Clean, focused interface

Design Tools Menu:

Design Mode Active:

This follows modern patterns where developer tools are hidden from end users by default, reducing visual complexity by ~40%.

+                            <DropdownMenuItem onClick={toggleDebug}>
+                              <MetadataToggle open={showDebug} onToggle={toggleDebug} className="hidden" />
+                              Metadata Inspector
+                            </DropdownMenuItem>


The "Metadata Inspector" menu item is missing an icon while the other menu items (Edit View, Add View) have icons with the "mr-2" spacing class. For consistency with the rest of the menu, add an icon (likely Code2 or similar) before the text to match the visual pattern.

+    // Design mode toggle - default false for end users
+    const [designMode, setDesignMode] = useState(false);

The new design mode toggle functionality lacks test coverage. Consider adding tests for:

Default state (design mode = false)

Toggling design mode via the dropdown menu

Metadata panel visibility tied to design mode state

Menu icon changes between MoreVertical and Wrench based on design mode

The existing ObjectView.test.tsx file shows the codebase has comprehensive test coverage for other features, so this new functionality should also be tested.

+  const [expandedSections, setExpandedSections] = useState<string[]>(['0']);
+  const [copiedIndex, setCopiedIndex] = useState<number | null>(null);
+
+  const handleCopy = async (data: any, index: number) => {
+    try {
+      await navigator.clipboard.writeText(JSON.stringify(data, null, 2));
+      setCopiedIndex(index);
+      setTimeout(() => setCopiedIndex(null), 2000);
+    } catch (err) {
+      console.error('Failed to copy:', err);
+    }
+  };
+
+  const toggleSection = (index: string) => {
+    setExpandedSections(prev =>
+      prev.includes(index)
+        ? prev.filter(i => i !== index)
+        : [...prev, index]
+    );
+  };


The new MetadataInspector features lack test coverage:

Collapsible sections functionality (expand/collapse behavior)

Copy to clipboard with visual feedback (Copy icon → Check icon)

Default expanded state (first section expanded by default)

Multiple section state management

The console app has comprehensive test coverage (23 test files) for other components, so these new features should also be tested.

+                <button
+                  onClick={() => toggleSection(sectionId)}
+                  className="flex-1 flex items-center justify-between text-left"
+                >
+                  <h4 className="text-xs font-semibold text-foreground">
+                    {section.title}
+                  </h4>
+                  {isExpanded ? (
+                    <ChevronDown className="h-3 w-3 text-muted-foreground ml-2" />
+                  ) : (
+                    <ChevronRight className="h-3 w-3 text-muted-foreground ml-2" />
+                  )}
+                </button>


The collapsible section buttons should have proper ARIA attributes for accessibility. Add aria-expanded={isExpanded} to the toggle button and consider wrapping in a proper semantic element like <summary> if appropriate, or at minimum add role="button" and aria-label with descriptive text for screen readers.

+                <button
+                  onClick={() => handleCopy(section.data, index)}
+                  className="p-1 hover:bg-muted rounded transition-colors ml-2"
+                  title="Copy JSON"
+                >
+                  {isCopied ? (
+                    <Check className="h-3 w-3 text-green-600" />
+                  ) : (
+                    <Copy className="h-3 w-3 text-muted-foreground" />
+                  )}
+                </button>


The copy button should have better accessibility. Add aria-label that changes based on the copied state (e.g., "Copy JSON" when not copied, "Copied!" when copied) to provide feedback to screen reader users about the action's success.

Copilot · 2026-02-11T08:01:22Z

+  const [expandedSections, setExpandedSections] = useState<string[]>(['0']);
+  const [copiedIndex, setCopiedIndex] = useState<number | null>(null);


The state initialization for expandedSections and copiedIndex inside the MetadataPanel component means that state will be reset every time the panel is closed and reopened. This provides a fresh start each time but may not be the ideal user experience.

Consider whether users would benefit from the panel remembering which sections were expanded when they reopen it. If persistence is desired, the state should be lifted to a parent component or stored in localStorage.

Copilot · 2026-02-11T08:01:22Z

+      setCopiedIndex(index);
+      setTimeout(() => setCopiedIndex(null), 2000);
+    } catch (err) {
+      console.error('Failed to copy:', err);


The copy error handling silently logs to console without providing user feedback. When clipboard access fails (common in non-HTTPS environments or when permissions are denied), users won't know why the copy didn't work.

Consider adding visual feedback for errors, such as showing a toast notification or changing the icon to an error state temporarily.

Suggested change

console.error('Failed to copy:', err);

console.error('Failed to copy:', err);

if (typeof window !== 'undefined') {

window.alert('Failed to copy to clipboard. Please check your browser permissions and try again.');

}

+                            <DropdownMenuItem onClick={toggleDebug}>
+                              <MetadataToggle open={showDebug} onToggle={toggleDebug} className="hidden" />
+                              Metadata Inspector
+                            </DropdownMenuItem>


The MetadataToggle component renders a Button, which creates nested interactive elements when used inside a DropdownMenuItem. This causes invalid HTML (button inside button) and accessibility issues.

Instead, the DropdownMenuItem should directly handle the toggle action and display appropriate text/icons without nesting the MetadataToggle component. The menu item should just call toggleDebug directly in its onClick handler, similar to how the other menu items work.
