Our CEO Damian Legawiec has recently been invited to present at ReactJS Warsaw meetup attended by a few dozens front end developers. The presentation included the introduction to Flux as well as examples of its practical implementations.
Based on 2 case studies from our recent projects milanstyle.com and greetabl.com, Damian explained that at Spark Solutions we use Flux for building rich & complex user interfaces because it simplifies the development process and grants us a higher quality of our front end code.
