QUESTION
I am trying to access the state.X of my store when Redux-watch store.subscribe() is triggered (by updating state.Y), but I can access just initial state values. I am using Redux-toolkit, React-redux, React-watch
When I call the "print" function after I press the UI button, my state is displayed with desired values, but when I call the "print" function in Redux-watch subscribe() function, the state.X has its initial values. Any idea what can be wrong?
Getting state from the store.
const date = useSelector((state) => state.calendar);
Print function: const print = () =>{console.log(date);}
Redux-watch subscribe function:

Though I did not find out why the variable "date" is in the time of the subscribe() method execution set to initial state value, I guess it's something with updating state in the time when the subscribe() function is called. So to get state in the subscribe() method:
QUESTION
Several of my components should be rendered only once, since then I just want them to listen to the changes in a global store and act correspondingly. But I can't make it: store.subscribe, and redux-watch I tried fired only when data has been dispatched but not when the store actually changed what means the corresponding function can't use this.props.bla because it's not updated yet. Is there some solution allowing to know when this.props.bla actually changed without using bla in the render function?

Answered 2020-Dec-27 at 23:53When you want to "respond" to a specific prop value updating then you should implement the componentDidUpdate lifecycle method. In your case if you need to know when the injected position prop value has updated, add a condition to compare the previous position prop value against the current position prop value.

Let's say i have a property in the store called state.items.byId each time this is updated (various parts of the application) i want to intercept the value before i'ts updated and run a function to update some properties on it before it's updated.
I don't know the terminology and i'm quite new to redux, but if someone could point me in the right direction that would be great!
I have searched and found redux-watch but i'm not 100% sure if this is the right approach

redux-watch provides you a subscription based mechanism notifying you after a property is changed. If you want to intercept a property before its changed you can write a custom middleware and handle any side-effects inside it.
QUESTION
I'm trying to differentiate different redux state changes and saw this github solution: Redux-watch In order to the watch function you're supposed to provide the redux store which can't figure out how to do. I'm passing the store down to this component through a provider for reference.
...ANSWER
Answered 2020-Feb-29 at 22:08If you need access to the store state in a component, you should be using the useSelector hook or the connect higher-order component. Don't try to set up store subscriptions yourself in components - React-Redux does that for you already.
