Angular uses a relatively classical MVC approach with two-way data binding. This makes it easy to getting started but with more complex applications this approach can be a problem when it comes to traceability of data flows and it can make it harder to extend and maintain an application. An alternative is Redux which is the de facto standard in the React community. Redux is both a pattern and a library that uses principles of functional programming to manage the state of an application. The restriction to one-way data flow, the explicit modelling of user actions and the usage of immutable data leads to better understandable processes in the app and also a better separation of concerns.Redux is not limited to React but instead is neutral to technology and can be used with Angular too. This talk will cover the idea and the principles of Redux and will show how to use Redux with Angular.
