Customizing the serializableStateInvariantMiddleware
Provide an example of how to configure the `serializableStateInvariantMiddleware` to ignore specific non-serializable values like dates or complex classes.
import { configureStore } from '@reduxjs/toolkit';
import { combineReducers } from 'redux';
import { createSerializableStateInvariantMiddleware } from '@reduxjs/toolkit';
const rootReducer = combineReducers({/* your reducers here */});
const isSerializable = (value) => {
// Implement custom serialization logic here.
// For example, check if the value is an instance of Date.
return value instanceof Date || /* other checks for serializability */;
};
const getEntries = (value) => {
// Retrieve entries of the value for serialization checks.
// Entries can be key-value pairs of Objects, Maps, etc.
return Object.entries(value);
};
const serializableMiddleware = createSerializableStateInvariantMiddleware({
isSerializable,
getEntries,
});
const store = configureStore({
reducer: rootReducer,
middleware: (getDefaultMiddleware) => getDefaultMiddleware().concat(serializableMiddleware),
});
export default store;
This code sets up a Redux store with a custom instantiation of the `serializableStateInvariantMiddleware`. The `isSerializable` function is provided to customize the serialization check. It determines whether a value is considered serializable, for example, by allowing instances of Date to bypass the check. The `getEntries` function is responsible for getting the entries of a given value, to be used by the middleware to check their serializability. The custom middleware is then added to the Redux store's middleware chain.
