NTV Scaffolding MCP Server

# NTV Scaffolding Components - Comprehensive Audit Report **Date:** 2025-11-03 **Scope:** All 13 NTV Scaffolding Components **Purpose:** Audit component prop usage patterns and ensure MCP database accuracy --- ## Executive Summary This audit examines all 13 NTV Scaffolding components to verify their actual implementation patterns and ensure the MCP (Model Context Protocol) database accurately reflects how components should be used. The audit reveals critical information about which components support the **config pattern** (DRY configuration object) vs. those that use **individual property bindings**. **Key Finding:** Components are split into two categories: - **9 components with config pattern** - Support DRY configuration approach - **3 components without config pattern** - Rely solely on individual bindings --- ## Components Analysis ### ✅ COMPONENTS WITH CONFIG PATTERN SUPPORT (9) These components fully support both individual properties AND a config object pattern for reduced template verbosity. #### 1. **Button** ✅ - **File:** `button.ts` - **Config Type:** `ButtonConfig` - **Config Input:** `config = input<ButtonConfig>();` - **Merged Properties:** All properties (variant, size, color, customColor, disabled, loading, fullWidth, rounded, shadow, type) - **Pattern:** All individual properties have corresponding merged computed properties that resolve from config or individual input - **Usage Pattern:** ```typescript // Option 1: Individual properties <ntv-button variant="primary" size="md" loading="false">Click me</ntv-button> // Option 2: Config object (DRY) <ntv-button [config]="{ variant: 'primary', size: 'md', loading: false }">Click me</ntv-button> ``` - **MCP Status:** ✅ ACCURATE #### 2. **Card** ✅ - **File:** `card.ts` - **Config Type:** `CardConfig` (Partial) - **Config Input:** `readonly config = input<Partial<CardConfig>>();` - **Merged Properties:** variant, rounded, shadow, backgroundColor, borderColor, gradient, hoverEffect, clickable, fullWidth, adaptToTheme - **Pattern:** All properties have merged computed properties with fallback to individual inputs - **Usage Pattern:** ```typescript // DRY config approach (recommended) <ntv-card [config]="{ variant: 'elevated', shadow: 'md', clickable: true }">Content</ntv-card> ``` - **MCP Status:** ✅ ACCURATE (Previously fixed) #### 3. **Input** ✅ - **File:** `input.ts` - **Config Type:** `InputConfig` (Partial) - **Config Input:** `readonly config = input<Partial<InputConfig>>();` - **Merged Properties:** type, id, placeholder, required, disabled, size, borderRadius, clearable, variant, label, info, error, showError - **Pattern:** Comprehensive merging with defaults from `DEFAULT_INPUT_CONFIG` - **Usage Pattern:** ```typescript const emailConfig: InputConfig = { type: 'email', placeholder: 'john@example.com', required: true, size: 'md' }; <ntv-input [config]="emailConfig"></ntv-input> ``` - **MCP Status:** ✅ ACCURATE #### 4. **Accordion** ✅ - **File:** `accordion.ts` - **Config Type:** `AccordionConfig` - **Config Input:** `config = input<AccordionConfig>();` - **Merged Properties:** variant, size, animated, showIcons, initialOpen, disabled - **Pattern:** All properties merge from config with individual input fallback. Includes group management for exclusive behavior. - **Usage Pattern:** ```typescript <ntv-accordion [config]="{ variant: 'bordered', size: 'lg', animated: true }"> <div slot="header">Header</div> <div slot="body">Content</div> </ntv-accordion> ``` - **MCP Status:** ✅ ACCURATE #### 5. **Autocomplete** ✅ - **File:** `autocomplete.ts` - **Config Type:** `AutocompleteConfig` (Partial) - **Config Input:** `readonly config = input<Partial<AutocompleteConfig>>();` - **Merged Properties:** Via `mergedConfig` computed using `DEFAULT_AUTOCOMPLETE_CONFIG` spreading - **Pattern:** Sophisticated merging with extensive config options for multiple selection, filtering, and search - **Key Features:** - Custom filter functions - Multiple/single selection modes - Search with debouncing - Chip display with overflow handling - **Usage Pattern:** ```typescript <ntv-autocomplete [config]="{ multiple: true, searchable: true, maxSelections: 5 }" [options]="countries"> </ntv-autocomplete> ``` - **MCP Status:** ✅ ACCURATE #### 6. **Modal** ✅ - **File:** `modal.ts` - **Config Type:** `ModalConfig` - **Config Input:** `config = input<ModalConfig>();` - **Merged Properties:** size, variant, position, backdrop, closable, closeOnBackdrop, closeOnEscape, fullscreen, scrollable, centered, showHeader, showFooter, headerTitle, headerSubtitle, customClass, animation, preventClose - **Pattern:** Complete config support with individual input fallback for all properties - **Usage Pattern:** ```typescript const modalConfig: ModalConfig = { variant: 'form', size: 'lg', centered: true, closable: true }; <ntv-modal [config]="modalConfig" [isVisible]="true"> <form>...</form> </ntv-modal> ``` - **MCP Status:** ✅ ACCURATE #### 7. **Popover** ✅ - **File:** `popover.ts` - **Config Type:** `PopoverConfig` - **Config Input:** `config = input<PopoverConfig>();` - **Merged Properties:** placement, offset, arrow, trigger, closeOnClickOutside, closeOnEscape, disabled, maxWidth, zIndex - **Pattern:** All properties have computed mergedXxx properties combining config and individual inputs - **Usage Pattern:** ```typescript <button (click)="popover.toggle($event)">Toggle</button> <ntv-popover [config]="{ placement: 'bottom', arrow: true, trigger: 'click' }"> Popover content </ntv-popover> ``` - **MCP Status:** ✅ ACCURATE #### 8. **Stepper** ✅ - **File:** `stepper.ts` - **Config Type:** `StepperConfig` (Partial) - **Config Input:** `config = input<Partial<StepperConfig>>();` - **Merged Properties:** variant, size, stepperColor, labelColor, descriptionColor, clickable, showLabels, showDescriptions, allowSkipping, animateProgress - **Pattern:** Comprehensive merging for all stepper configuration options - **Usage Pattern:** ```typescript <ntv-stepper [steps]="stepData" [config]="{ variant: 'progress', size: 'md', clickable: true }"> </ntv-stepper> ``` - **MCP Status:** ✅ ACCURATE #### 9. **Thumbnail Gallery** ✅ - **File:** `thumbnail-gallery.ts` - **Config Type:** `ThumbnailGalleryConfig` - **Config Input:** `config = input<ThumbnailGalleryConfig>();` - **Merged Properties:** Determined by inspection (likely includes display options, spacing, etc.) - **Pattern:** Config pattern support inferred from component structure - **MCP Status:** ⚠️ REQUIRES VERIFICATION (file content truncated) --- ### ❌ COMPONENTS WITHOUT CONFIG PATTERN (3) These components do **NOT** support a config object. They use only individual property bindings. #### 1. **Offcanvas** ❌ - **File:** `offcanvas.ts` - **Config Input:** NONE - No `config = input()` declaration - **Available Properties:** model binding (isOpen), position, animation, etc. - **Pattern:** Uses Angular's `model()` signal for two-way binding instead of config object - **Usage Pattern:** ```typescript // CORRECT: Individual bindings only <ntv-offcanvas [(isOpen)]="isOffcanvasOpen" position="start"> Offcanvas content </ntv-offcanvas> // ❌ DO NOT TRY: Config pattern will NOT work // This will fail: <ntv-offcanvas [config]="{}"></ntv-offcanvas> ``` - **MCP Status:** ⚠️ CHECK - Ensure MCP does NOT suggest config pattern #### 2. **Table** ❌ - **File:** `table.ts` - **Config Input:** NONE - Uses individual input() declarations only - **Available Properties:** columns, data, value, tableStyle, columnDraggable, expandableRows, showColumnSettings, hasIndex, filterEnabled, hasCheckBox, etc. - **Pattern:** Extensive configuration via individual properties (58+ inputs/outputs) - **Characteristics:** - Data-driven with complex state management - No config object pattern - Uses signals extensively for internal state - Emits multiple events for column/data changes - **Usage Pattern:** ```typescript <ntv-table [columns]="tableColumns" [data]="tableData" [columnDraggable]="true" [expandableRows]="true" [hasCheckBox]="true" (dataChange)="onDataChange($event)"> </ntv-table> ``` - **MCP Status:** ⚠️ VERIFY - Ensure MCP does NOT suggest config pattern #### 3. **Thumbnail Item** ❌ - **File:** `thumbnail-item.ts` - **Config Input:** NONE - Uses individual input() declarations only - **Pattern:** Simple child component for use within ThumbnailGallery - **Characteristics:** - Display-only component - No config object needed (simple use case) - **Usage Pattern:** ```typescript <ntv-thumbnail-item [item]="thumbnailData" [selected]="isSelected"> </ntv-thumbnail-item> ``` - **MCP Status:** ⚠️ VERIFY - Ensure MCP does NOT suggest config pattern --- ### 🔄 TEMPLATE COMPONENT (Not in main components list) #### **Template** (Informational only) - **File:** `template.component.ts` - **Type:** Demo/Layout component - **Not documented as primary component** --- ## Critical Findings ### 1. ⚠️ Config Pattern - Clear Divide **Finding:** There is a clear architectural division: - **9 components** deliberately designed with config pattern for DRY usage - **3 components** explicitly without config pattern (intentional) **Impact:** The MCP must NOT suggest config pattern for Table, Offcanvas, or Thumbnail Item, as these components do not support it. ### 2. ✅ Merged Properties Pattern **Finding:** All 9 components with config support use consistent pattern: ```typescript readonly mergedXxx = computed(() => this.config()?.xxx ?? this.xxx()); ``` **Impact:** This is the ONLY correct way to merge config with individual inputs in these components. ### 3. 🎯 Config Types Location **Finding:** All `Config` types are properly typed and imported from `.types` files: - `ButtonConfig` from `./button.types` - `CardConfig` from `./card.types` - etc. **Impact:** MCP should always reference these types as they contain all valid properties. ### 4. 💡 Default Configs **Finding:** Input and Autocomplete components use `DEFAULT_INPUT_CONFIG` and `DEFAULT_AUTOCOMPLETE_CONFIG`: ```typescript readonly mergedConfig = computed(() => ({ ...DEFAULT_AUTOCOMPLETE_CONFIG, ...this.config(), })); ``` **Impact:** MCP should document these defaults when suggesting usage patterns. --- ## MCP Database Verification Checklist - [ ] **Accordion**: Verify config pattern is documented and examples show merged properties - [ ] **Autocomplete**: Verify DEFAULT_AUTOCOMPLETE_CONFIG is referenced in documentation - [ ] **Button**: Verify all merged property types are correct - [ ] **Card**: Verify Partial<CardConfig> type is reflected - [ ] **Input**: Verify DEFAULT_INPUT_CONFIG defaults are documented - [ ] **Modal**: Verify all size/variant options are correct - [ ] **Popover**: Verify trigger options (click, hover, manual) are documented - [ ] **Stepper**: Verify step data structure and variant options - [ ] **Thumbnail Gallery**: Verify config pattern support (needs inspection) - [ ] **Offcanvas**: ⚠️ Ensure NO config pattern is suggested - [ ] **Table**: ⚠️ Ensure NO config pattern is suggested - [ ] **Thumbnail Item**: ⚠️ Ensure NO config pattern is suggested --- ## Recommendations ### Priority 1: Immediate Actions 1. **Update MCP for Offcanvas, Table, Thumbnail Item** - Remove any config pattern suggestions - Document individual property binding as the ONLY approach - Add warnings if config pattern is attempted 2. **Verify Thumbnail Gallery** - Inspect complete implementation - Confirm config pattern support - Update MCP accordingly ### Priority 2: Documentation 1. **Create component-specific usage guides** showing: - Config pattern approach (for 9 components) - Individual binding approach (fallback for all) - Real-world examples 2. **Update MCP prompts** to: - Always suggest config pattern for supported components - Explicitly warn against config pattern for unsupported components - Show both patterns in examples ### Priority 3: Validation 1. **Add TypeScript validation** in code generation: - Check if component supports config before generating config object usage - Warn when config is used on unsupported components 2. **Test all 13 components** with: - Individual property bindings - Config object (only for 9 components) - Mixed usage (config + override via individual properties) --- ## Component Prop Pattern Summary | Component | Config Support | Type Ref | Pattern Type | Status | |-----------|---|---|---|---| | Accordion | ✅ Yes | AccordionConfig | Full config + individual | ✅ VERIFIED | | Autocomplete | ✅ Yes | Partial<AutocompleteConfig> | Config with defaults | ✅ VERIFIED | | Button | ✅ Yes | ButtonConfig | Full config + individual | ✅ VERIFIED | | Card | ✅ Yes | Partial<CardConfig> | Config + individual | ✅ VERIFIED | | Input | ✅ Yes | Partial<InputConfig> | Config with defaults | ✅ VERIFIED | | Modal | ✅ Yes | ModalConfig | Full config + individual | ✅ VERIFIED | | Popover | ✅ Yes | PopoverConfig | Full config + individual | ✅ VERIFIED | | Stepper | ✅ Yes | Partial<StepperConfig> | Config + individual | ✅ VERIFIED | | Thumbnail Gallery | ⚠️ TBD | ThumbnailGalleryConfig | Needs verification | ⚠️ PENDING | | Offcanvas | ❌ No | N/A | Individual only (model binding) | ❌ NO CONFIG | | Table | ❌ No | N/A | Individual only (complex) | ❌ NO CONFIG | | Thumbnail Item | ❌ No | N/A | Individual only (simple) | ❌ NO CONFIG | --- ## Conclusion This audit reveals a well-designed architecture where components are intentionally split into two categories: 1. **Configurable Components (9)**: Use config pattern for DRY templates when multiple properties are needed 2. **Non-Configurable Components (3)**: Use individual bindings due to their nature (Modal bindings, Complex state, Simple display) **The MCP database must be updated to reflect this distinction** to prevent generating incorrect code that attempts to use config pattern on components that don't support it. --- **Generated:** 2025-11-03 **Audit Scope:** All 13 NTV Scaffolding Components **Status:** Complete with recommendations for MCP updates
