The Reactor Bill of Materials (BOM) is a curated set of compatible versions for Project Reactor modules such as reactor-core, reactor-netty, reactor-extra, and reactor-pool. It is imported into Maven or Gradle builds so that all Reactor dependencies can be declared without explicit version numbers.

Use cases

• manage consistent Reactor library versions across a Maven project
• import reactor-bom in Gradle to avoid pinning individual versions
• align reactor-core and reactor-netty versions in a Spring Boot WebFlux app
• upgrade all Project Reactor modules to a compatible release train at once
• avoid version conflicts between reactive JVM dependencies

When to choose

• you use multiple Project Reactor modules and want guaranteed version compatibility
• you build reactive JVM applications with Spring WebFlux, RSocket, or R2DBC
• you want a single place to upgrade your reactive stack

When to avoid

• you only need a single Reactor artifact and can pin its version directly
• your project does not use reactive or non-blocking JVM libraries
• you need the reactive libraries themselves rather than version coordination
