Before +const users = await Database.getUsers() + +// After +const result = await dbal.users.list() +const users = result.data +``` + +### Step 4: Add Authentication Context +```typescript +function

Install Dependencies + +The DBAL uses Prisma, which is already installed in MetaBuilder: +```bash +# Already done - Prisma is in package.json +``` + +### 2. Import the DBAL Client + +```typescript +import { getDBALClient } from '@/lib/dbal-client' +import type { User } from '@/lib/level-types' + +// Get client (with or without user context) +const client = getDBALClient() + +// Or with authentication (enables ACL) +const client = getDBALClient(currentUser, { + id: 'session_123', + token: 'abc' +}) +``` + +### 3. Use CRUD Operations + +```typescript +// Create +const user = await client.users.create({ + username: 'alice', + email: 'alice@example.com', + role: 'user' +}) + +// Read +const foundUser = await client.users.read(user.id) + +// Update +await client.users.update(user.id, { + email: 'alice.new@example.com' +}) + +// List with filters +const admins = await client.users.list({ + filter: { role: 'admin' }, + sort: { createdAt: 'desc' }, + limit: 20 +}) + +// Delete +await client.users.delete(user.id) +``` + +### 4. Handle Errors + +```typescript +import { DBALError, DBALErrorCode } from '../../dbal/ts/src' + +try { + await client.users.read('nonexistent_id') +} catch (error) { + if (error instanceof DBALError) {

toast.error('Database error') + } + } +} +``` + +## Key Features + +### 🔒 Security (ACL) + +Automatic role-based access control: + +```typescript +// User with role 'user' can only read/update their own records +const client = getDBALClient(currentUser, session) +await client.users.update(currentUser.id, { email: 'new@example.com' }) // ✅ OK +await client.users.update(otherUser.id, { email:

OK +``` + +### 📝 Audit Logging + +All operations are logged automatically: + +```json +{ + "timestamp": "2024-01-15T10:30:00.000Z", + "user": "alice", + "role": "admin", + "entity": "User", + "operation": "create", + "success": true +} +``` + +Check browser console for `[DBAL Audit]` logs. + +### 🎯 Type Safety + +Full TypeScript support: + +```typescript +import type { User, PageView, ComponentHierarchy } from '../../dbal/ts/src' + +// Type-safe entities +const user: User = await client.users.create({ ... }) +const page: PageView = await client.pages.create({ ... }) +const

+client.users.delete(id) +client.users.list(options) +``` + +### Pages +```typescript +client.pages.create(data) +client.pages.read(id) +client.pages.readBySlug(slug) // Special: find by slug +client.pages.update(id, data) +client.pages.delete(id) +client.pages.list(options) +``` + +### Components +```typescript +client.components.create(data) +client.components.read(id) +client.components.update(id, data) +client.components.delete(id) +client.components.getTree(pageId) // Special: get all components for a page +``` + +## Common Patterns + +### List with Pagination + +```typescript +const result = await client.users.list({ + filter: { role: 'admin' }, + sort: { createdAt: 'desc' }, + page: 1, + limit: 20 +}) + +console.log(`Showing ${result.data.length} of ${result.total} users`) +if (result.hasMore) { + console.log('More results available') +} +``` + +### Conditional ACL + +```typescript +// Disable ACL for system operations +const systemClient = getDBALClient() // No user context + +// Enable ACL for user operations +const userClient = getDBALClient(currentUser, session) +``` + +### Check Capabilities + +```typescript +const capabilities =
