Example Hilla microservice application

This example application demonstrates how to use Hilla to call microservices. Hilla follows a backends-for-frontends pattern, where each frontend has its own backend. The frontend is responsible for aggregating data from multiple services and presenting it to the user.

Hilla uses type-safe RPC calls to communicate between the frontend and backend.

The example consists of 3 applications:

• user-service - A service that provides user data
• order-service - A service that provides order data
• hilla-app - The frontend application that aggregates data from the other services
