Conceptual guidance for designing reliable interfaces and communication between frontend and backend systems.
Frontend–Backend integration outlines concepts and patterns for reliable communication between user interfaces and backend systems. It covers API design, data models, authentication, error handling and performance aspects. The goal is loose coupling, clear contracts and scalable communication to improve maintainability, security and observability.
Measure of 95th percentile latency for typical API calls; important for UX.
Proportion of erroneous responses; indicator for stability and compatibility.
Number of processed requests per second; relevant for scaling planning.
Frontend consumes REST services for catalog, cart and checkout; clear API contracts and contract tests were introduced.
Dashboard uses GraphQL backend for aggregated data; schema federation enables modular growth.
Client syncs locally modified data with backend; conflict rules and backoff strategies are implemented.
Create API specification (OpenAPI/GraphQL)
Provide mock server and develop frontend against mock
Implement backend, introduce contract tests and integrate CI
Define monitoring, logging and SLOs
