Backend Development Patterns
Patterns
- •Repository Pattern: Abstract data access logic.
- •Service Layer Pattern: Business logic separated from data access.
- •Middleware Pattern: Request/response processing pipeline (e.g.,
withAuth).
Database
- •Optimization: Select only needed columns.
- •N+1 Prevention: Use batch fetching.
- •Transactions: Use RPC or transaction blocks for atomic operations.
Error Handling
- •Centralized Handler: Use standard Error classes and response structures.
- •Exponential Backoff: Use for retrying external API calls.
