Event-Sourcing your React-Flux applications

Most React-Flux applications just store the data being edited as is in a database. It is perfectly fine to treat data in a simple CRUD fashion like this with a smaller application. However this is not optimal when applications get more complex. For more complex applications using the Command Query Responsibility Segregation (CQRS) design pattern is better. And cobining this with Event-Sourcing (ES) is an even more powerful solution. With Event-Sourcing every action leading up to the current state is stored as a separate domain event. This collection of domain events is then used as the write model in the CQRS model. These same events are projected out to a secondary database to build the read model for the application. In this session Maurice de Beijer will explain why you might want to use Event-Sourcing and how to get started with this design in your React and Flux applications.
