const nextConfig: NextConfig = { /* config */ }
export default nextConfig
```
- ✅ Type-safe configuration
- ✅ ESM export pattern

API Routes
- ✅ NextRequest and NextResponse imports from next/server
- ✅ Proper async handlers with try-catch
- ✅ Type-safe response handling
- ✅ Query parameter extraction from request.nextUrl.searchParams
Client Components
- ✅ 'use client' directive at top of file
- ✅ Proper hook usage (useState, useEffect, useRef)
- ✅ Props typed with TypeScript interfaces
- ✅ Server/Client component separation
File Structure
- ✅ App Router (app/ directory)
- ✅ Route handlers in route.ts files
- ✅ Layouts and pages properly structured

React 19.2.3 ✅

Implementation: Functional components with hooks
Patterns Validated:

Component Structure
- ✅ Functional components only (no class components)
- ✅ 'use client' for interactive components
- ✅ Props interfaces defined with TypeScript
Hooks Usage
- ✅ useState for state management
- ✅ useEffect for side effects
- ✅ useRef with proper TypeScript typing (useRef<THREE.Mesh>(null!))
- ✅ Custom hooks in app/lib/hooks/
Type Safety
- ✅ All components properly typed
- ✅ Props interfaces exported and reused
- ✅ Event handlers with correct types

Database Layer

Prisma 7.3.0 ✅

Library ID: /prisma/docs
Code Snippets: 7,702
Benchmark Score: 86.6

Validated Patterns:

Adapter Configuration

import { PrismaPg } from '@prisma/adapter-pg';
import { Pool } from 'pg';
   
const pool = new Pool({ connectionString: process.env.DATABASE_URL });
const adapter = new PrismaPg(pool);

✅ Using @prisma/adapter-pg version 7.3.0
✅ PostgreSQL connection pooling with pg.Pool
✅ Adapter pattern (required for Prisma 7)

Client Singleton

const globalForPrisma = globalThis as unknown as {
  prisma: PrismaClient | undefined;
};
   
export const prisma =
  globalForPrisma.prisma ??
  new PrismaClient({
    adapter,
    log: process.env.NODE_ENV === 'development' ? ['query', 'error', 'warn'] : ['error'],
  });
   
if (process.env.NODE_ENV !== 'production') globalForPrisma.prisma = prisma;

✅ Singleton pattern for development (prevents multiple instances)
✅ Conditional logging based on environment
✅ Global reference to prevent hot-reload issues

Schema Configuration
```
datasource db {
  provider = "postgresql"
}
```
- ✅ No url in datasource (adapter provides connection)
- ✅ Proper PostgreSQL provider
- ✅ Generator configured correctly
Query Patterns
- ✅ Relations with include properly used
- ✅ findMany with pagination (skip, take)
- ✅ where clauses with proper typing
- ✅ Transactions for multi-step operations

Background Jobs

BullMQ 5.67.1 ✅

Library ID: /taskforcesh/bullmq
Code Snippets: 1,180
Benchmark Score: 87.1

Validated Patterns:

Redis Connection

import Redis from 'ioredis';
   
const connection = new Redis(process.env.REDIS_URL || 'redis://localhost:6379', {
  maxRetriesPerRequest: null,
  enableReadyCheck: false,
});

✅ maxRetriesPerRequest: null (required for BullMQ)
✅ enableReadyCheck: false (recommended for BullMQ)
✅ Using ioredis 5.9.2

Queue Configuration

export const aiJobQueue = new Queue('ai-jobs', {
  connection,
  defaultJobOptions: {
    attempts: 3,
    backoff: {
      type: 'exponential',
      delay: 2000,
    },
    removeOnComplete: {
      count: 100,
    },
    removeOnFail: {
      count: 500,
    },
  },
});

✅ Exponential backoff strategy
✅ Retry attempts configured
✅ Auto-cleanup policies (removeOnComplete/removeOnFail)
✅ Shared connection instance

Job Options
- ✅ attempts for retry count
- ✅ backoff.type and backoff.delay for retry strategy
- ✅ Job data properly typed with TypeScript
- ✅ Queue names as constants

Runtime & Build Tools

Bun.js 1.3.6 ✅

Library ID: /oven-sh/bun
Validated in: app/scripts/ziit/ directory

Validated Patterns:

Process Spawning
```
const proc = Bun.spawn(["git", "status"]);
const output = await proc.stdout.text();
```
- ✅ Bun.spawn() for process execution
- ✅ proc.stdout.text() for reading output (not new Response().text())
- ✅ Proper error handling with stderr
File System Operations
- ✅ Using standard fs module (Bun-compatible)
- ✅ fs.watch() for file monitoring
- ✅ fs.statSync() for file checks
- ✅ No usage of Bun-specific APIs that don’t exist in 1.3.6
Package Management
- ✅ bun install as default package manager
- ✅ npm fallback for CI/CD compatibility
- ✅ Lock file: bun.lockb

3D Graphics

Three.js 0.182.0 + React Three Fiber 9.5.0 ✅

Library IDs:

/pmndrs/react-three-fiber (Benchmark: 77.2)
/pmndrs/drei (Benchmark: 90.3)

Validated in: app/app/components/ClosetRail.tsx

Validated Patterns:

Canvas Setup

import { Canvas } from '@react-three/fiber';
import { OrbitControls, PerspectiveCamera } from '@react-three/drei';
import { Suspense } from 'react';
   
<Canvas>
  <Suspense fallback={null}>
    {/* 3D content */}
  </Suspense>
</Canvas>

✅ Canvas component as root
✅ Suspense for lazy loading
✅ Drei helpers properly imported

Texture Loading

import * as THREE from 'three';
   
const loader = new THREE.TextureLoader();
loader.load(
  item.thumbnailUrl,
  (loadedTexture) => { setTexture(loadedTexture); },
  undefined,
  (error) => { console.error('Error loading texture:', error); }
);

✅ THREE.TextureLoader() pattern
✅ Async loading with callbacks
✅ Error handling
✅ State management with React hooks

Mesh Components

const meshRef = useRef<THREE.Mesh>(null);
   
<mesh ref={meshRef} position={position}>
  <boxGeometry args={[1, 1, 1]} />
  <meshStandardMaterial color="orange" />
</mesh>

✅ Typed refs (useRef<THREE.Mesh>)
✅ Lowercase primitives (mesh, geometry, material)
✅ Props as JSX attributes

Controls and Camera
- ✅ OrbitControls from @react-three/drei
- ✅ PerspectiveCamera configuration
- ✅ Proper position arrays [x, y, z]

Validation & Types

Zod 4.3.6 ✅

Library ID: /colinhacks/zod/v4.0.1
Code Snippets: 552
Benchmark Score: 92.7

Validated in: app/app/api/items/route.ts

Validated Patterns:

Schema Definition

import { z } from 'zod';
   
const createItemSchema = z.object({
  title: z.string().optional(),
  category: z.enum([
    'tops',

    'dresses',
    // ...
  ]).optional(),
  colorPalette: z.array(z.string()).optional(),
  attributes: z.record(z.string(), z.any()).optional(),
});

✅ z.object() for object schemas
✅ z.enum() for enum validation
✅ z.array() for arrays

✅ z.record() for dynamic key-value objects

Type Inference
```
type CreateItemInput = z.infer<typeof createItemSchema>;
```
- ✅ z.infer<typeof Schema> for type extraction
- ✅ Type-safe throughout the application
Validation Usage
- ✅ Schema validation in API routes
- ✅ Error handling with try-catch
- ✅ Proper error messages returned to client
