Managing state with React only
I understand that if you're creating an application using React only, you will end up managing all of your state within different React components you create.
Managing state with React and Redux
If you decide to use Redux in combination with React, you can then move all of the state from each of your React components into the overall Redux application state. Each component that requires a slice of the Redux application state can then hook into the state via React-Redux's connect
function.
Question
Does this mean that you no longer need to write any React components that deal with React's state
(ie this.setState
) since React-Redux is connect
ing the React components with Redux state by passing data into the container
component as props
?
There are different opinions on this, but the general view seems to be that redux should only contain "application state". Individual react components like dropdowns or modals will still have their own state.
There is still a lot of debate on this though, check out this issue for example about how to manage local component state: https://github.com/reactjs/redux/issues/159
Some projects have been popping up that are trying to solve this "problem":
