Solution

To persist state in a Redux application, you can use a middleware like redux-persist. Here are the steps:

  1. Install redux-persist using npm or yarn. For npm, use npm install redux-persist and for yarn, use yarn add redux-persist.

  2. Import persistReducer and persistStore from redux-persist in your store configuration file.

  3. Create a persistConfig object. This object will have the configuration for your persistence. The key and storage properties are required. The key is a string that will be used as a prefix for your persisted data and the storage property is where you want to store your persisted state.

  4. Wrap your root reducer with persistReducer. This will enhance your root reducer with persistence capabilities.

  5. Create your Redux store as you normally would, but also call persistStore with your store as an argument. This will create a persistor
