Should you store data in Redux?
There is no “right” answer for this. Some users prefer to keep every single piece of data in Redux, to maintain a fully serializable and controlled version of their application at all times. Others prefer to keep non-critical or UI state, such as “is this dropdown currently open”, inside a component’s internal state.
What data should we store in Redux?
As an app gets large and complex, you might want to store large, bulky data inside your Redux store and access it inside a component. A Redux store doesn’t have a limit on the amount of data stored, so you can pretty much use it to store almost anything, including bulky JSON data, data in table form, etc.
What is the use of store in Redux?
A store is an immutable object tree in Redux. A store is a state container which holds the application’s state. Redux can have only a single store in your application. Whenever a store is created in Redux, you need to specify the reducer.

Why we use Redux in angular?

Is Redux a local storage?
Redux as per the official documentation is a predictable state container for JavaScript apps. Persisting the data of such react apps is very easy. We will be using local storage to store the current state of the React app and persist the data even on reloads.
Is Redux a backend?
However, since Redux is just JavaScript, it can also be used on the server side (backend). One good example of using Redux on the backend is with multiplayer games that run within a browser and need to store their state on the server to ensure all players have the same view of the game.
How to read data from the Redux store?
React components can read data from the Redux store using the useSelector hook from the React-Redux library. The “selector functions” that you write will be called with the entire Redux state object as a parameter, and should return the specific data that this component needs from the store.
What are the arguments to the postadded function in Redux?
Inside of reducers, add a function named postAdded, which will receive two arguments: the current state value, and the action object that was dispatched. Since the posts slice only knows about the data it’s responsible for, the state argument will be the array of posts by itself, and not the entire Redux state object.
Why do reducer functions need to be included in Redux?
Reducer functions need to have some initial data included so that the Redux store has those values loaded when the app starts up. For now, we’ll create an array with some fake post objects inside so that we can begin adding the UI.
Where is the global store located in Redux?
With Redux, we get a global store. This store lives at the highest level of your app and passes data down to all children. You connect to the global store with the connect wrapper and a mapStateToProps function. At first, people put everything in the Redux store.
