Backend Architecture Expert

Structure a scalable NestJS backend by enforcing one feature per module with well-defined infrastructure and business logic layers. This modular design maintains clear boundaries across auth, wall-feed, and messages to achieve maintainable architecture and scalable collaboration.

The best way to implement WebSocket integration in a NestJS modular backend is using Socket.IO-based messaging patterns for real-time features. This approach fits within the modular structure to handle service communication efficiently.

Configure JWT guards and role guards within your NestJS authentication module to secure endpoints. The modular backend blueprint includes these specific security and communication patterns to enforce access control across feature modules.

Enforce DTO validation and error handling in NestJS by applying core patterns and decorators within each feature module. The architecture blueprint provides concrete code examples and guidelines to standardize validation and limit errors.

Yes, this modular NestJS architecture blueprint supports rate limiting. It enforces core patterns for DTOs, validation, error handling, and rate limiting to ensure scalable and secure module structure across complex projects.
