Framework-Specific Search Patterns

1. Express.js (Node.js)

**Route Definitions:**

# Standard routes
rg "app\.(get|post|put|delete|patch|all)" --type js

# Router instances
rg "router\.(get|post|put|delete|patch)" --type js

# Route files
rg "express\.Router\(\)" --type js

**Middleware & Auth:**

# Authentication middleware
rg "app\.use\(.*auth" --type js
rg "passport\." --type js
rg "jwt\.|bearer" --type js

# Validation middleware
rg "express-validator|joi|yup" --type js

**Example Analysis:**

// Find: app.post('/api/users', authenticate, validateUser, createUser)
// Document:
// - Endpoint: POST /api/users
// - Auth: Required (authenticate middleware)
// - Validation: validateUser middleware
// - Handler: createUser

2. FastAPI / Flask (Python)

**FastAPI Routes:**

# Route decorators
rg "@app\.(get|post|put|delete|patch)" --type py

# Router instances
rg "@router\.(get|post|put|delete)" --type py

# Path parameters
rg "path: (str|int)" --type py

# Pydantic models (schemas)
rg "class.*\(BaseModel\)" --type py

**Flask Routes:**

# Route decorators
rg "@app\.route\(" --type py
rg "@blueprint\.route\(" --type py

# Methods
rg "methods=\[" --type py

**Auth & Dependencies:**

# Dependencies
rg "Depends\(" --type py

# Auth
rg "OAuth2PasswordBearer|HTTPBearer" --type py
rg "@login_required" --type py

3. Django (Python)

**URL Patterns:**

# URL configurations
rg "path\(|re_path\(|url\(" --type py

# Views
rg "def (get|post|put|delete)\(" --type py
rg "class.*\(APIView\)" --type py

# DRF ViewSets
rg "class.*\(ViewSet|ModelViewSet\)" --type py

# Serializers (schemas)
rg "class.*\(Serializer|ModelSerializer\)" --type py

**Auth:**

# Permission classes
rg "permission_classes|IsAuthenticated" --type py

# Auth decorators
rg "@login_required|@permission_required" --type py

4. Spring Boot (Java)

**Controllers & Endpoints:**
