Calling RESTful services the reactive way with Helidon
summary
Creates a Helidon SE WebClient v2.1.0 (Netty-based) with builder-mounted features: JSON-P media support, baseUri, per-request headers and optional keep‑alive. Executes reactive calls that return a Helidon Single (hybrid CompletionStage/reactive) and demonstrates blocking with await for a main method. Live demo calls GET /greet (prints "hello world"), GET /greet/{name}, follows redirects (enabled by builder, default max 5), PUT /greet to update the greeting (verified by chaining flatMap), and header override — all examples run successfully.
