Helidon is a cloud-native, open‑source set of Java libraries for writing microservices that run on a fast web core powered by Netty.
Helidon supports two programming models:
- Helidon MP: MicroProfile 3.3.
- Helidon SE: a small, functional style API.
This is free and open source software.
Key Features
- Designed to be simple to use, with tooling and examples to get you going quickly. Since Helidon is simply a collection of Java libraries running on a fast Netty core, there is no extra overhead or bloat.
- Full MicroProfile support – supports MicroProfile and provides familiar APIs like JAX-RS, CDI and JSON-P/B.
- Reactive WebServer – provides a modern functional programming model and runs on top of Netty. Lightweight, flexible and reactive, the Helidon WebServer provides a simple-to-use and fast foundation for your microservices.
- Observable and Resilient – support for health checks, metrics, tracing and fault tolerance. Write cloud-ready applications that integrate with Prometheus, Jaeger/Zipkin and Kubernetes.
- GraalVM Native Image Support – supports GraalVM Native Image so you can compile your Helidon application into a small-footprint native executable. Or you can package your application as a jlink image or a traditional application JAR.
- Persistence Support – fully supports DB connectivity. Its non-blocking database client supports existing blocking JDBC drivers as well as relational and non-relational databases.
- Reactive streams messaging.
