Server-Sent Events (SSE) with Java and Spring Boot | Build a News Feed App

[@yassineraddaoui5467]

thank you so much , can you give me some tips how to learn spring boot and spring flux

[@Code.Wizzard]

Thanks for the comment. I would suggest to first get an in depth understanding of Spring Web before starting with web flux. We have one video on Spring Web which is a short one - kzbin.info/www/bejne/n4PMe6R_aNR0p6M. Planning to do a detailed crash course sometime soon. There are some nice courses in Spring Academy which are good for beginners like spring.academy/courses/building-a-rest-api-with-spring-boot. Also check some popular crash courses in KZbin. Along with the courses start building some projects. That is the best way to learn.

What if we have to fetch the data from db

[@Code.Wizzard]

Usually, for real-time use cases, messages are pushed to your app via queue/topic or by calling your API by a client/external app. But if you want to push data from a DB over SSE, you can poll the DB at regular intervals for new data and push this data incrementally to the client using an SseEmitter. Hope that answers your question.
