Other Exports

redux-starter-kit exports some of its internal utilities, and re-exports additional functions from other dependencies as well.

Internal Exports

createSerializableStateInvariantMiddleware

Creates an instance of the serializable-state-invariant middleware described in getDefaultMiddleware.

Accepts an options object with an isSerializable parameter, which will be used to determine if a value is considered serializable or not. If not provided, this defaults to isPlain.

Example:

import {configureStore, createSerializableStateInvariantMiddleware} from "redux-starter-kit";

const serializableMiddleware = createSerializableStateInvariantMiddleware({
    isSerializable: () => true // all values will be accepted
});

const store = configureStore({
    reducer,
    middleware : [serializableMiddleware],
});

isPlain

The default function used to determine if a value is considered serializable.

Current definition:

function isPlain(val) {
  return (
    typeof val === 'undefined' ||
    val === null ||
    typeof val === 'string' ||
    typeof val === 'boolean' ||
    typeof val === 'number' ||
    Array.isArray(val) ||
    isPlainObject(val)
  )
}

Exports from Other Libraries

createNextState

The default immutable update function from the immer library, re-exported here as createNextState (also commonly referred to as produce)

combineReducers

Redux's combineReducers, re-exported for convenience. While configureStore calls this internally, you may wish to call it yourself to compose multiple levels of slice reducers.

compose

Redux's compose. It composes functions from right to left. This is a functional programming utility. You might want to use it to apply several store custom enhancers/ functions in a row.
