Due to the specificities of frontend applications, modeling the domain in this context has always been challenging. Ranging from generating aggregate ids and designing their lifecycles, to the need to represent invalid states, to context mapping when communicating with vendor APIs, there are a series of factors to be considered when modeling the domain. In this talk, I will show you these specificities and how to tackle everyday frontend complexities using canonical DDD concepts, designing new bounded contexts just for the frontend, while still embracing modern frontend approaches.
