Project reactor debugging in intellij

Viewed 2755

I am new to reactive programming and still learning. In traditional or imperative programming , i typically put break point in intellij and debug java code but not able to do the same with reactive code. Is there any plugin available to debug reactive spring boot api?

IntelliJ has support for Reactor debugging since 2019.3 IIRC. They've been improving their async debugger, take into account when the application uses reactor-tools, etc...

See the reference guide for enabling reactor-tools "debug agent", then in IntelliJ go to Preferences > Languages&Frameworks > Reactive Streams to enable support.
