bff-gateway

A BFF gateway manages the backend-for-frontend layer by orchestrating frontend-oriented API requests and aggregating responses from internal microservices into a unified output. It handles routing, proxy behavior, and request shaping for web clients.

You aggregate data from multiple microservices by using a BFF gateway layer to route external requests to appropriate internal services, fetch associated data, and combine these multiple backend responses into a single unified frontend response.

Yes, this BFF gateway requires compatibility with ECS/Fargate and existing routing patterns. It is designed to manage auth/session-aware gateway behavior and route protection within those specific container deployment environments.

A backend-for-frontend proxy manages auth and session context securely by enforcing route protection and maintaining session-aware gateway behavior. This ensures that frontend API requests are safely authenticated before being proxied to internal microservices.

You should use API request aggregation when a web client needs unified data from multiple backend services. Instead of making direct microservice calls, the BFF gateway combines associated data into a single response to reduce client-side complexity.

The best way to modify gateway routing patterns is to first analyze the repository to understand the current gateway responsibilities. This ensures any changes to proxy behavior, route protection, or API orchestration maintain compatibility with existing patterns.
