For sqlx, we want to make sure we include the "postgres" feature during compilation, so we have PostgreSQL drivers to connect to our PostgreSQL database with. Next, we'll want to make sure we have the runtime-actix-native-tls feature included so that sqlx can support the actix-web framework which uses the tokio runtime. Finally, let's include serde and serde_json for serializing our Health Check API response body for later in the post.

This /health API endpoint solution is an implementation of the Health Check API pattern, a pattern for checking the health of your API service. In web frameworks like Spring a drop-in solution like Spring Actuator is available for you to integrate into your Spring project. However, in many web frameworks you have to build this Health Check API behavior yourself.
