At Mendix we use MobX to manage the state of our visual enterprise application studio. In this talk we will take a look behind the scenes and see how MobX simplifies concerns like authentication, data fetching and routing. The strong decoupling of state and UI helps us to iterate on our UI more quickly. The architecture of the studio is pluggable and we will see how MobX helps integrating external producers and consumers of state into the product. In the end, we believe that this approach results in a code base that is sane and accessible. In which we get things done quickly. ReactNext 2016 Tel Aviv, Israel
