# KBX Foundation v60 — Phase 3 Integration Guide

**날짜**: 2026-08-15  
**상태**: ✅ COMPLETE  
**목표**: Registry, Composables, App Initialization 통합

---

## 📦 Phase 3 구성

### 1️⃣ Design Tokens (tokens.css)
```
Color palette (OMS/ERP/WMS/COMMON)
Spacing system (compact/comfortable/touch)
Typography (xs/sm/base/lg/xl)
Component heights & densities
Transitions & shadows
Dark mode support
```

### 2️⃣ Registry System (3개)

#### ScreenRegistry
```typescript
// 화면 정의 관리
register(screen: KbxScreenDefinition)
getScreen(id: string)
getScreensByModule(module)
getScreensByTemplate(templateCode)
```

#### PermissionRegistry
```typescript
// 권한 정의 관리
register(permission: KbxPermissionDefinition)
getPermission(id: string)
getPermissionsByCategory(category)
```

#### HelpRegistry
```typescript
// 도움말 내용 관리
register(definition: KbxHelpDefinition)
getHelp(screenId: string)
```

### 3️⃣ Composables (3개)

#### useKbxValidation
```typescript
// 폼 검증 상태 관리
errors, hasErrors
getFieldError(field), hasFieldError(field)
getRowFieldError(rowKey, field)
setErrors(errors), addError(field, message)
clear(), applyProblem(problem)
```

#### useKbxDirtyState
```typescript
// 수정되지 않은 변경사항 추적
dirty
isFieldDirty(field), markFieldDirty(field)
markAllClean(), markAllDirty()
getDirtyFields(), reset()
```

#### useKbxPermission
```typescript
// 권한 확인 및 RBAC
has(permission), hasAny([perms]), hasAll([perms])
canView(requiredPermissions)
canEdit(permission), canDelete(permission)
setPermissions([perms]) // 로그인 후 호출
```

### 4️⃣ App Initialization

#### installKbx(app, options)
```typescript
// Vue 앱에 KBX 설치
installKbx(app, {
  screens: [...],
  permissions: [...],
  help: [...],
  userPermissions: ['order.view', 'order.create'],
  density: 'compact',
  theme: 'auto'
})
```

#### Density Control
```typescript
setDensity('compact' | 'comfortable' | 'touch')
getDensity()
```

#### Theme Control
```typescript
setTheme('light' | 'dark')
getTheme()
toggleTheme()
isDarkMode()
```

---

## 💡 사용 예제

### 1. App 초기화 (main.ts)

```typescript
import { createApp } from 'vue'
import { installKbx } from '@/shared/@kbx'
import App from './App.vue'

const app = createApp(App)

// KBX 시스템 설치
installKbx(app, {
  screens: allScreenDefinitions,
  permissions: allPermissions,
  help: allHelpContent,
  density: 'compact',
  theme: 'auto'
})

app.mount('#app')
```

### 2. Screen 등록 (features/orders/registry.ts)

```typescript
import { defineKbxScreen } from '@/shared/@kbx'

export const orderListScreen = defineKbxScreen({
  id: 'oms.orders.list',
  version: '1.0',
  module: 'OMS',
  type: 'list',
  templateCode: 'T01',
  title: '주문 관리',
  description: '주문 목록 조회 및 관리',
  permissions: ['order.view'],
  helpKey: 'oms.orders.list'
})

export const orderRegisterScreen = defineKbxScreen({
  id: 'oms.orders.register',
  version: '1.0',
  module: 'OMS',
  type: 'transaction',
  templateCode: 'T03',
  title: '주문 등록',
  permissions: ['order.create'],
})
```

### 3. Form 페이지 (features/orders/pages/OrderRegister.vue)

```vue
<script setup lang="ts">
import { ref } from 'vue'
import {
  KbxTransactionTemplate,
  KbxInput,
  KbxSelect,
  KbxButton,
} from '@/shared/@kbx'
import {
  useKbxValidation,
  useKbxDirtyState,
} from '@/shared/@kbx'

const form = ref({
  customerCode: '',
  deliveryAddress: '',
  items: []
})

const { errors, hasErrors, setErrors, addError } = useKbxValidation()
const { dirty, markFieldDirty, markAllClean } = useKbxDirtyState({
  customerCode: false,
  deliveryAddress: false,
})

const validate = () => {
  errors.clear()
  if (!form.value.customerCode) {
    addError('customerCode', '거래처를 선택하세요')
  }
  return !hasErrors.value
}

const submit = async () => {
  if (!validate()) return

  try {
    await api.orders.register(form.value)
    markAllClean()
  } catch (error: any) {
    setErrors(error.response.data.errors || [])
  }
}
</script>

<template>
  <KbxTransactionTemplate
    header-title="주문 정보"
    detail-title="주문 상품"
    :detail-count="form.items.length"
    :errors="errors"
    :dirty="dirty"
  >
    <template #header>
      <KbxInput
        v-model="form.customerCode"
        label="거래처"
        :error="errors.getFieldError('customerCode')"
        required
        @blur="markFieldDirty('customerCode')"
      />
      <KbxInput
        v-model="form.deliveryAddress"
        label="배송지"
        :error="errors.getFieldError('deliveryAddress')"
        @blur="markFieldDirty('deliveryAddress')"
      />
    </template>

    <template #detail>
      <!-- Order items grid -->
    </template>

    <template #summary>
      <KbxButton
        variant="primary"
        label="저장"
        :disabled="hasErrors"
        @click="submit"
      />
    </template>
  </KbxTransactionTemplate>
</template>
```

### 4. Permission Guard (Router)

```typescript
import { createRouter } from 'vue-router'
import { getGlobalPermissions } from '@/shared/@kbx'

const router = createRouter({
  history: createWebHistory(),
  routes: [
    {
      path: '/orders/register',
      component: () => import('./pages/OrderRegister.vue'),
      beforeEnter: (to, from, next) => {
        const perms = getGlobalPermissions()
        if (perms.has('order.create')) {
          next()
        } else {
          next('/403')
        }
      }
    }
  ]
})
```

### 5. Using Registry

```typescript
import { useScreenRegistry } from '@/shared/@kbx'

export default {
  setup() {
    const { 
      getScreensByModule,
      getCountByModule,
      hasScreen 
    } = useScreenRegistry()

    // OMS 모듈 화면 목록
    const omsScreens = getScreensByModule('OMS')
    
    // OMS 화면 수
    const omsCount = getCountByModule('OMS')
    
    // 특정 화면 존재 여부
    const hasOrderList = hasScreen('oms.orders.list')
  }
}
```

## 🎨 Density & Theme Control

### Density 전환

```typescript
// UI 밀도 전환 (compact → comfortable → touch)
import { setDensity, getDensity } from '@/shared/@kbx'

setDensity('comfortable')
const current = getDensity() // 'comfortable'
```

**적용 내용:**
- `--kbx-input-height`: 34px → 36px → 48px
- `--kbx-grid-row-height`: 34px → 36px → 48px
- `--kbx-touch-target`: 44px → 48px → 52px
- `--kbx-font-size`: 14px → 14px → 16px

### Theme 전환

```typescript
import { 
  setTheme, 
  getTheme, 
  toggleTheme, 
  isDarkMode 
} from '@/shared/@kbx'

// 명시적 설정
setTheme('dark')
setTheme('light')

// 자동 (시스템 설정 따름)
setTheme('auto') // 또는 removeAttribute('data-theme')

// 토글
toggleTheme()

// 확인
const isDark = isDarkMode() // true/false
```

---

## 📊 Registry Pattern

### Screen Registry 사용

```typescript
// 모듈별 화면 그룹화
const omsScreens = getScreensByModule('OMS')
const wmsScreens = getScreensByModule('WMS')

// 특정 템플릿 화면 찾기
const listScreens = getScreensByTemplate('T01')
const masterScreens = getScreensByTemplate('T02')

// 전체 화면 이동 수 계산
const totalScreens = getAllScreens()
  .reduce((acc, entry) => acc + entry.screen.type === 'list' ? 1 : 0, 0)
```

### Permission Registry 사용

```typescript
// 권한별 화면 확인
const createPermissions = getPermissionsByCategory('order')
createPermissions.forEach(perm => {
  console.log(perm.label) // "주문 생성", "주문 삭제", ...
})
```

---

## 🔌 Router Integration Template

```typescript
import { createRouter, createWebHistory } from 'vue-router'
import { screenRegistry } from '@/shared/@kbx'
import { getGlobalPermissions } from '@/shared/@kbx'

// 동적 라우트 생성 (registry 기반)
const dynamicRoutes = screenRegistry.getAllScreens()
  .map(entry => ({
    path: entry.screen.id.replace(/\./g, '/'),
    component: entry.screen.component,
    meta: {
      screenId: entry.screen.id,
      permissions: entry.screen.permissions || [],
      title: entry.screen.title
    }
  }))

const router = createRouter({
  history: createWebHistory(),
  routes: [
    ...dynamicRoutes,
    {
      path: '/:pathMatch(.*)*',
      component: () => import('./NotFound.vue')
    }
  ]
})

// 라우트 가드
router.beforeEach((to, from, next) => {
  const perms = getGlobalPermissions()
  const requiredPerms = to.meta.permissions

  if (requiredPerms && !perms.hasAll(requiredPerms)) {
    next('/403')
    return
  }

  next()
})

export default router
```
