Sample Spring Native Application to explore reactive support.

Application accesses GitHub, DevTo & StackOverflow api's to fetch user specific informations.

Exposed API's can be consumed to build a social dashboard.

All endpoints are reactive.

Include Oracle R2DBC driver with Spring R2DBC impl.

# fetch StackOverflow data
@GetMapping(value = "/sov", produces = MediaType.TEXT_EVENT_STREAM_VALUE)

# fetch github data
@GetMapping(value = "/gith", produces = MediaType.TEXT_EVENT_STREAM_VALUE)

# fetch DevTo data
@GetMapping(value = "/devto", produces = MediaType.TEXT_EVENT_STREAM_VALUE)

.....
public interface PersonRepository extends ReactiveCrudRepository<Person, Long> {
}
.....

# generate native image with graalvm plugin [ you can use spring boot native image plugin as well ].
$ mvn clean -Pnative-image package

• Plain spring-boot run takes over 1 sec vs native image starts in about ~300ms.
