Subject: [PATCH] Enhance Custom Node Components with Shape Class and Style
 Updates

- Added a computed property for dynamic shape classes in custom node components (ApiNode, BusinessRuleNode, FormNode, GatewayNode, HtmlNode, NotificationNode, ScriptNode, SubprocessNode) to support various shapes.
- Updated the class bindings in the template to include the new shape classes, improving visual representation of nodes based on their defined shapes.
- Adjusted styles in `nodeStyles.js` to accommodate new shape types (hexagon, trapezoid) and ensure proper rendering without conflicting base styles.
- Enhanced the process builder interface by refining node styles and ensuring consistent behavior across different node types.

+
+## 📋 System Overview
+
+This is a **Vue 3 + Nuxt 3** application that provides a visual process builder using **Vue Flow** library. The system allows users to create, edit, and manage business processes through a drag-and-drop interface with custom nodes and edges.
+
+### 🏗️ **Core Architecture**
+- **Frontend**: Vue 3 with Composition API + Nuxt 3
+- **Flow Engine**: Vue Flow (Vue 3 compatible fork of React Flow)
+- **Styling**: Tailwind CSS + Custom SCSS
+- **State Management**: Pinia stores
+- **Database**: Prisma ORM
+- **UI Components**: Custom component library + FormKit
+

+
+## 🔄 How the System Works
+
+### **1. Vue Flow Integration**
+
+#### **Main Canvas Component** (`ProcessFlowCanvas.vue`)
+```vue
+<template>
+  <VueFlow
+    v-model:nodes="nodes"
+    v-model:edges="edges"
+    :node-types="customNodeTypes"
+    :edge-types="customEdgeTypes"
+    @error="handleVueFlowError"
+  >
+    <Background />
+    <Controls />
+    <MiniMap />
+  </VueFlow>
+</template>
+
+<script setup>
+import { markRaw } from 'vue'
+// Import all custom node components
+import StartNode from './custom/StartNode.vue'
+import FormNode from './custom/FormNode.vue'
+// ... other imports
+
+// Register node types with Vue Flow
+const customNodeTypes = {
+  'start': markRaw(StartNode),
+  'form': markRaw(FormNode),
+  'api': markRaw(ApiNode),
+  // ... other node types
+}
+</script>
+```
+
+#### **Custom Node Structure**
+Every custom node follows this pattern:
+
+```vue
+<script setup>
+import { Handle, Position } from '@vue-flow/core'
+import { computed } from 'vue'
+
+// Props from Vue Flow
+const props = defineProps([
+  'id',           // Node ID
+  'type',         // Node type
+  'label',        // Node label  
+  'selected',     // Selection state
+  'data'          // Custom data object
+])
+
+// Shape class for dynamic styling
+const shapeClass = computed(() => {
+  const shape = props.data?.shape || 'rectangle'
+  return `shape-${shape}`
+})
+
+// Node styling
+const nodeStyle = computed(() => ({
+  '--node-bg-color': props.data?.backgroundColor || 'white',
+  '--node-border-color': props.data?.borderColor || '#ddd',
+  '--node-text-color': props.data?.textColor || 'black'
+}))
+</script>
+
+<template>
+  <div 
+    :class="['custom-node', 'node-form', shapeClass, { 'selected': selected }]"
+    :style="nodeStyle"
+  >
+    <!-- Input handles -->
+    <Handle type="target" :position="Position.Left" />
+    
+    <!-- Node content -->
+    <div class="custom-node-content">
+      <div class="custom-node-header">
+        <span class="material-icons">description</span>
+        <span class="custom-node-title">{{ data?.label || 'Form' }}</span>
+      </div>
+      <!-- Additional content -->
+    </div>
+    
+    <!-- Output handles -->
+    <Handle type="source" :position="Position.Right" />
+  </div>
+</template>
+```
+
+### **2. Node Shape System**
+
+#### **Shape Configuration**
+Nodes support multiple shapes through CSS `clip-path`:
+
+```javascript
+// Available shapes
+const shapes = [
+  'rectangle',      // Default rectangle
+  'rounded-rectangle', // Rounded corners
+  'circle',         // Circle shape
+  'diamond',        // Diamond (gateway nodes)
+  'hexagon',        // Hexagon shape
+  'trapezoid',      // Trapezoid shape
+  'parallelogram'   // Parallelogram shape
+]
+```
+
+#### **Shape CSS Implementation** (`nodeStyles.js`)
+```css
+/* Rectangle (default) */
+.custom-node.shape-rectangle {
+  border-radius: 4px;
+}
+
+/* Hexagon shape */
+.custom-node.shape-hexagon {
+  background: none !important;
+  border: none !important;
+  border-radius: 0 !important;
+}
+
+.custom-node.shape-hexagon::before {
+  content: '';
+  position: absolute;
+  top: 0; left: 0; right: 0; bottom: 0;
+  background: var(--node-bg-color, white);
+  border: 2px solid var(--node-border-color, #ddd);
+  clip-path: polygon(25% 0%, 75% 0%, 100% 50%, 75% 100%, 25% 100%, 0% 50%);
+  z-index: 0;
+}
+
+/* Node-type specific colors for shapes */
+.node-form.shape-hexagon::before {
+  border-left: 4px solid #9333ea; /* Purple */
+}
+```
+
+### **3. Node Types & Configurations**
+
+#### **Node Type Registry** (`processFlowNodes.js`)
+```javascript
+export const nodeTypes = {
+  'start': {
+    label: 'Start',
+    icon: 'play_circle',
+    color: '#10b981',
+    allowedShapes: ['circle', 'rectangle'],
+    defaultData: {
+      label: 'Start',
+      backgroundColor: '#dcfce7',
+      borderColor: '#10b981'
+    }
+  },
+  'form': {
+    label: 'Form',
+    icon: 'description',
+    color: '#9333ea',
+    allowedShapes: ['rectangle', 'rounded-rectangle', 'hexagon', 'trapezoid'],
+    defaultData: {
+      label: 'Form Task',
+      formId: null,
+      required: true
+    }
+  },
+  // ... other node types
+}
+```
+
+### **4. Process Builder State Management**
+
+#### **Pinia Store** (`stores/processBuilder.js`)
+```javascript
+export const useProcessBuilderStore = defineStore('processBuilder', () => {
+  // State
+  const nodes = ref([])
+  const edges = ref([])
+  const selectedNode = ref(null)
+  const processDefinition = ref({})
+  
+  // Actions
+  const addNode = (nodeData) => {
+    const newNode = {
+      id: generateId(),
+      type: nodeData.type,
+      position: nodeData.position,
+      data: { ...nodeTypes[nodeData.type].defaultData, ...nodeData.data }
+    }
+    nodes.value.push(newNode)
+  }
+  
+  const updateNode = (nodeId, updates) => {
+    const nodeIndex = nodes.value.findIndex(n => n.id === nodeId)
+    if (nodeIndex > -1) {
+      nodes.value[nodeIndex] = { ...nodes.value[nodeIndex], ...updates }
+    }
+  }
+  
+  return {
+    nodes, edges, selectedNode, processDefinition,
+    addNode, updateNode
+  }
+})
+```
+
+---
+
+## 🛠️ Implementation Patterns
+
+### **1. Adding a New Node Type**
+
+#### **Step 1: Create Node Component**
+```bash
+# Create new component file
+touch components/process-flow/custom/YourNewNode.vue
+```
+
+```vue
+<!-- YourNewNode.vue -->
+<script setup>
+import { Handle, Position } from '@vue-flow/core'
+import { computed } from 'vue'
+
+const props = defineProps(['id', 'type', 'label', 'selected', 'data'])
+
+const shapeClass = computed(() => {
+  const shape = props.data?.shape || 'rectangle'
+  return `shape-${shape}`
+})
+</script>
+
+<template>
+  <div :class="['custom-node', 'node-yournew', shapeClass, { 'selected': selected }]">
+    <Handle type="target" :position="Position.Left" />
+    <div class="custom-node-content">
+      <span class="material-icons">your_icon</span>
+      <span>{{ data?.label || 'Your Node' }}</span>
+    </div>
+    <Handle type="source" :position="Position.Right" />
+  </div>
+</template>
+```
+
+#### **Step 2: Register in ProcessFlowCanvas.vue**
+```javascript
+// Import the component
+import YourNewNode from './custom/YourNewNode.vue'
+
+// Add to customNodeTypes
+const customNodeTypes = {
+  // ... existing types
+  'yournew': markRaw(YourNewNode),
+}
+```
+
+#### **Step 3: Add Node Configuration**
+```javascript
+// In processFlowNodes.js
+export const nodeTypes = {
+  // ... existing types
+  'yournew': {
+    label: 'Your New Node',
+    icon: 'your_icon',
+    color: '#your-color',
+    allowedShapes: ['rectangle', 'circle'],
+    defaultData: {
+      label: 'Your New Node',
+      yourProperty: 'default-value'
+    }
+  }
+}
+```
+
+#### **Step 4: Add Styling**
+```css
+/* In nodeStyles.js */
+.node-yournew {
+  background: white;
+  border: 1px solid #ddd;
+  border-left: 4px solid #your-color;
+}
+```
+
+### **2. Adding Shape Support**
+
+#### **Step 1: Define Shape CSS**
+```css
+/* In nodeStyles.js */
+.custom-node.shape-yourshape {
+  background: none !important;
+  border: none !important;
+  border-radius: 0 !important;
+}
+
+.custom-node.shape-yourshape::before {
+  content: '';
+  position: absolute;
+  top: 0; left: 0; right: 0; bottom: 0;
+  background: var(--node-bg-color, white);
+  border: 2px solid var(--node-border-color, #ddd);
+  clip-path: polygon(/* your shape points */);
+  z-index: 0;
+}
+```
+
+#### **Step 2: Add to Shape Lists**
+```javascript
+// In processFlowNodes.js or relevant config
+const availableShapes = [
+  // ... existing shapes
+  'yourshape'
+]
+
+// Add to node type configurations
+'form': {
+  allowedShapes: ['rectangle', 'hexagon', 'yourshape']
+}
+```
+
+### **3. Customizing Node Properties**
+
+#### **Properties Panel Integration**
+```vue
+<!-- In node component -->
+<script setup>
+const props = defineProps(['id', 'type', 'label', 'selected', 'data'])
+
+// Computed properties for dynamic behavior
+const isRequired = computed(() => props.data?.required || false)
+const formId = computed(() => props.data?.formId)
+const customProperties = computed(() => props.data?.customProperties || {})
+</script>
+
+<template>
+  <div class="custom-node">
+    <!-- Display based on properties -->
+    <div v-if="isRequired" class="required-indicator">*</div>
+    <div class="node-content">
+      {{ data?.label || 'Default Label' }}
+    </div>
+  </div>
+</template>
+```

+
+## 🎨 Styling System
+
+### **CSS Architecture**
+1. **Global Styles** (`nodeStyles.js`) - Injected globally via plugin
+2. **Component Styles** - Scoped styles in individual `.vue` files
+3. **Tailwind Classes** - Utility classes for layout and spacing
+4. **CSS Variables** - Dynamic theming support
+
+### **CSS Variable System**
+```css
+/* Node supports dynamic styling via CSS variables */
+.custom-node {
+  background: var(--node-bg-color, white);
+  border-color: var(--node-border-color, #ddd);
+  color: var(--node-text-color, black);
+}
+```
+
+```javascript
+// Set in component
+const nodeStyle = computed(() => ({
+  '--node-bg-color': props.data?.backgroundColor || 'white',
+  '--node-border-color': props.data?.borderColor || '#ddd',
+  '--node-text-color': props.data?.textColor || 'black'
+}))
+```
+
+### **Shape Override Pattern**
+```css
+/* Base node styles */
+.node-form {
+  background: white;
+  border: 1px solid #ddd;
+  border-radius: 4px;
+}
+
+/* Shape overrides */
+.node-form.shape-hexagon {
+  background: none !important;
+  border: none !important;
+  border-radius: 0 !important;
+}
+```
+
+---
+
+## 🔌 Plugin System
+
+### **Vue Flow Styles Plugin** (`process-flow-styles.client.js`)
+```javascript
+export default defineNuxtPlugin(() => {
+  // Inject global styles for Vue Flow nodes
+  if (process.client) {
+    const { injectGlobalStyles } = useNodeStyles()
+    injectGlobalStyles()
+  }
+})
+```
+
+### **CodeMirror Integration** (`vue-codemirror.js`)
+```javascript
+export default defineNuxtPlugin(() => {
+  // Register CodeMirror for script editing
+  // Used in ScriptNode and ApiNode components
+})
+```
+
+---
+
+## 📊 Data Flow
+
+### **Process Definition Structure**
+```json
+{
+  "id": "process-uuid",
+  "name": "Process Name",
+  "version": "1.0.0",
+  "nodes": [
+    {
+      "id": "node-1",
+      "type": "start",
+      "position": { "x": 100, "y": 100 },
+      "data": {
+        "label": "Start Process",
+        "backgroundColor": "#dcfce7",
+        "shape": "circle"
+      }
+    }
+  ],
+  "edges": [
+    {
+      "id": "edge-1",
+      "source": "node-1",
+      "target": "node-2",
+      "type": "default"
+    }
+  ],
+  "variables": {},
+  "settings": {}
+}
+```
+
+### **Node Data Structure**
+```javascript
+// Standard node data properties
+{
+  id: 'unique-node-id',
+  type: 'form|api|script|gateway|etc',
+  position: { x: number, y: number },
+  data: {
+    // Universal properties
+    label: 'Node Label',
+    shape: 'rectangle|circle|hexagon|etc',
+    backgroundColor: '#ffffff',
+    borderColor: '#dddddd',
+    textColor: '#000000',
+    
+    // Type-specific properties
+    formId: 'form-uuid',        // For form nodes
+    apiEndpoint: 'url',         // For API nodes
+    scriptCode: 'javascript',   // For script nodes
+    conditions: [],             // For gateway nodes
+    
+    // Custom properties
+    customProperties: {}
+  }
+}
+```

+
+## 🐛 Common Issues & Solutions
+
+### **1. Nodes Not Displaying in Production**
+**Problem**: Custom nodes show as empty boxes in production build.
+**Solution**: Use file-based components with `markRaw()` wrapper.
+
+```javascript
+// ❌ Wrong - breaks in production
+const nodeTypes = {
+  'form': {
+    template: '<div>Form Node</div>'
+  }
+}
+
+// ✅ Correct - works in production
+import FormNode from './custom/FormNode.vue'
+const nodeTypes = {
+  'form': markRaw(FormNode)
+}
+```
+
+### **2. Shapes Not Displaying**
+**Problem**: Node shapes remain rectangular despite shape selection.
+**Solution**: Ensure shape CSS overrides base styles with `!important`.
+
+```css
+/* ❌ Wrong - base styles override */
+.custom-node.shape-hexagon {
+  border-radius: 0;
+  background: none;
+}
+
+/* ✅ Correct - overrides base styles */
+.custom-node.shape-hexagon {
+  border-radius: 0 !important;
+  background: none !important;
+  border: none !important;
+}
+```
+
+### **3. Handle Connection Issues**
+**Problem**: Nodes can't connect to each other.
+**Solution**: Ensure handles have proper `type` and `position`.
+
+```vue
+<!-- ✅ Correct handle setup -->
+<Handle 
+  type="target" 
+  :position="Position.Left"
+  :isConnectable="true"
+/>
+<Handle 
+  type="source" 
+  :position="Position.Right"
+  :isConnectable="true"
+/>
+```
