Episode notes
Helidon Declarative's Key Innovation
- Helidon Declarative enhances Helidon SE with build-time dependency injection without reflection.
- It generates concrete Java sources, improving performance and debugging over runtime reflection.
Source Code Generation Advantage
- Helidon generates Java source files, not bytecode like Lombok, allowing easy inspection and modification.
- This real source code aids debugging and transparency in Helidon Declarative.
Use Maven Plugin for Zero Reflection
- Use Maven annotation processors or Helidon plugin to generate sources placed in the standard generated-sources directory.
- Always use the plugin to achieve zero reflection during runtime service loading.
