FF4J: Feature Toggling for Spring/Spring Boot Applications

Feature toggling is a technique used to enable or disable certain behaviors of the system (typically at runtime). This makes release management much easier (e.g., Dark Launching, Canary Releases, Blue-Greed Deploy, A/B testing, etc.). Many leading companies (such as Facebook, DropBox, and Google) use these techniques to gradually release and test new features to a small set of their users before releasing to everyone. This technique can also be used as an alternative to maintaining multiple feature branches, and thus can reduce the cost of long-lived branches. There are commercial and open-source frameworks available in different technologies to help implement feature toggling. Among those, FF4J is a very good Java-based, open-source framework that addresses most of the feature toggle aspects and works very well with mircroservices/Spring Boot particularly, with very easy integration. This session will demonstrate feature toggling using FF4J framework for Spring/SpringBoot applications.

Very informative and all these feature are need of time as I see many project has it with complex logic. Good to see easy way to create and maintain features.

[@abuyousufsajal918]

can you provide full end to end system design? I am unable to run due to Database configuration. whrere is the scema and data? And anyone have re-designed and implemented it?

[@srikanthgoud2479]

is ff4j work with angular as well?

Unfortunately FF4J development has stagnated since 2020. You might want to use Togglz instead.

[@michaeldeng1981]

Maybe I misunderstand it. But to be honest, I'm not convinced to use FF4J, the code will end up with tons of "if..else": This looks not pretty.

That is where you should try the AOP feature of this framework, you can use a knife to cut an apple or your finger tool is the same

Just not able to follow very well because of her thick accent :(

[@causeno1048]

Neither an Indian nor English native speaker and I could follow. Try setting the speed to 0.75.

[@FredrikRambris]

I gave up.

[@rubendariofrancodiaz6944]

I don't see wha's wrong with that, she has an accent but is totally understandable.
