Implement 10 missing field widgets per @objectstack/spec UI protocol #253

Copilot · 2026-01-28T17:19:37Z

ObjectUI field widget coverage was at 59% (19/32 types) relative to @objectstack/spec v0.3.3. This adds the 10 missing widget implementations to achieve 91% coverage.

Added Field Widgets

Input Controls

ColorField - Color picker with hex input/preview
SliderField - Range slider (configurable min/max/step)
RatingField - Star rating (configurable max stars)
CodeField - Monospace code editor

Complex Inputs

AvatarField - Profile picture uploader with base64 encoding
AddressField - Structured address (street/city/state/zip/country)
GeolocationField - Lat/long with browser geolocation API integration
SignatureField - Canvas-based signature capture

Specialized

QRCodeField - QR code generator/display
MasterDetailField - One-to-many relationship editor

Implementation

All widgets follow the FieldWidgetProps<T> interface pattern with readonly/editable mode support:

export function ColorField({ value, onChange, field, readonly }: FieldWidgetProps<string>) {
  if (readonly) {
    return (
      <div className="flex items-center gap-2">
        <div className="w-6 h-6 rounded border" style={{ backgroundColor: value }} />
        <span>{value}</span>
      </div>
    );
  }
  // ... editable mode
}

Registered in ComponentRegistry with both direct type ('color') and prefixed variant ('field:color') for consistency with existing patterns.

Coverage

Field widget implementation: 19/32 → 29/32 types (91%)

Remaining 3 types are aliases handled by existing widgets (richtext/html → RichTextField).

Original prompt

按照@objectstack/spec ui协议继续开发完成所有组件

Pull request overview

This PR implements 10 missing field widget components to improve ObjectUI's coverage of the @objectstack/spec UI protocol from 59% to 91% (29/32 field types). The new widgets provide input controls for colors, ratings, code, avatars, addresses, geolocation, signatures, and QR codes, plus a master-detail relationship editor.

Changes:

Added 10 new field widget components following the FieldWidgetProps<T> interface pattern with readonly/editable mode support
Updated component registry to include both direct type registrations ('color') and prefixed variants ('field:color')
Replaced placeholder LookupField registration for master_detail type with dedicated MasterDetailField implementation
Added basic test coverage for all new widgets

packages/fields/src/widgets/QRCodeField.tsx

+  const getQRCodeUrl = (text: string): string => {
+    // Using a simple QR code API service (you might want to replace this with a library)
+    return `https://api.qrserver.com/v1/create-qr-code/?size=200x200&data=${encodeURIComponent(text)}`;
+  };


The QRCodeField uses an external third-party API (api.qrserver.com) without HTTPS enforcement or error handling. This introduces several concerns:

Security: The URL uses 'https://' but there's no guarantee the service will remain available or secure

Privacy: Sensitive data in QR codes would be sent to an external service

Reliability: No fallback if the API is unavailable

Performance: Network latency for external API calls

Consider using a client-side QR code library instead (e.g., 'qrcode.react' or 'qrcode') to keep data processing local and ensure reliability.

packages/fields/src/widgets/MasterDetailField.tsx

+    // This would typically navigate to the detail view
+    console.log('View detail:', item);


The handleView function only logs to console instead of implementing actual navigation or detail view functionality. This placeholder implementation should either be properly implemented (e.g., through an event callback prop) or clearly documented as requiring custom integration by the consumer.

Suggested change

// This would typically navigate to the detail view

console.log('View detail:', item);

/**

* Default "view" behavior:

* - If the item includes a `url` property, open it in a new tab.

* - Otherwise, no-op.

*

* Consumers that need custom navigation or detail views should either:

* - Provide a `url` field on each item, or

* - Wrap this field widget and override the click behavior externally.

*/

const url = (item as any).url;

if (typeof window !== 'undefined' && typeof url === 'string' && url.length > 0) {

window.open(url, '_blank', 'noopener,noreferrer');

}

packages/fields/src/widgets/GeolocationField.tsx

+  const openInMaps = () => {
+    if (!location.latitude || !location.longitude) return;
+    const url = `https://www.google.com/maps?q=${location.latitude},${location.longitude}`;
+    window.open(url, '_blank');


The openInMaps function uses window.open with '_blank' target without setting 'noopener,noreferrer' for security. This can expose the parent window to potential security vulnerabilities through the window.opener reference. Consider using window.open(url, '_blank', 'noopener,noreferrer') to prevent the opened page from accessing the parent window.

Suggested change

window.open(url, '_blank');

window.open(url, '_blank', 'noopener,noreferrer');

packages/fields/src/widgets/AvatarField.tsx

+    // Convert to base64 or upload to server
+    const reader = new FileReader();
+    reader.onloadend = () => {
+      onChange(reader.result as string);
+    };
+    reader.readAsDataURL(file);
+  };


Converting large images (up to 5MB) to base64 can significantly increase memory usage and data size (base64 encoding increases size by ~33%). Additionally, storing base64 images in component state and potentially in a database can cause performance issues. Consider:

Adding a warning about base64 limitations in the documentation

Optionally supporting direct file upload to a storage service

Reducing the max file size or adding compression before encoding

Implementing image resizing before base64 conversion to optimize for avatar use cases (typically 256x256 or similar)

packages/fields/src/widgets/GeolocationField.tsx

+      console.error('Geolocation is not supported by this browser');
+      return;
+    }
+
+    setIsLoading(true);
+    navigator.geolocation.getCurrentPosition(
+      (position) => {
+        onChange({
+          latitude: position.coords.latitude,
+          longitude: position.coords.longitude,
+          accuracy: position.coords.accuracy,
+        });
+        setIsLoading(false);
+      },
+      (error) => {
+        console.error('Error getting location:', error.message);
+        setIsLoading(false);


Error handling uses console.error without providing user feedback. When geolocation fails (browser doesn't support it or user denies permission), users won't see a visible error message. Consider displaying the error in the UI or leveraging the errorMessage prop available in FieldWidgetProps.

packages/fields/src/widgets/SignatureField.tsx

+ * Signature field widget - provides a signature pad for capturing signatures
+ * Outputs signature as a base64 PNG image
+ */
+export function SignatureField({ value, onChange, readonly }: FieldWidgetProps<string>) {


The SignatureField doesn't use the 'field' parameter at all, unlike other widgets that typically access field.placeholder, field.label, or custom properties. While this might be intentional for this specific widget, it's inconsistent with the pattern seen in other widgets. Consider whether the field prop should be used for configuration (e.g., canvas dimensions, stroke color/width) or mark it as optional in the destructuring if it's genuinely not needed.
