I breathe easy between services by declarative REST clients, removing boilerplate REST code.

Hints

Commonly annotated with @FeignClient("service-name")

Integrates with Ribbon for client-side load balancing

Creates interfaces that map to remote REST endpoints

My endpoints expose health, metrics, and runtime information for apps.

Hints

Extends with custom endpoints via @Endpoint or @WebEndpoint

Helps monitor and manage applications in production

Provides /health, /metrics, and more endpoints
