Building HTTP Applications with Ratpack
summary
Ratpack is a Java 8 library (usable from Java and Groovy) for building HTTP/REST microservices on Netty-based non‑blocking IO to achieve low memory use and high concurrency for cheap cloud deployment. The talk demonstrates a runnable Groovy/Java app with Gradle and lazybones templates, handler chains with path parameters, JSON/XML rendering via Jackson modules, Hystrix and templating modules, use of promises/execution blocks to offload blocking DB calls, live‑reload and fast Spock tests.
