Redux Storage Middleware is a lightweight middleware for Redux that persists state to storage backends (e.g., localStorage) and rehydrates it on app load. Current stable version is 1.1.292. It is maintained by sequencemedia and requires Node >=18.12.0. It distinguishes itself from alternatives like redux-persist by being minimal, with no built-in transforms or migrations, and relies on the storage engine provided by the developer.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import storageMiddleware from 'redux-storage-middleware'

✗ const storageMiddleware = require('redux-storage-middleware').default

ESM only; default export is the middleware function.

createStorage

✓ import { createStorage } from 'redux-storage-middleware'

✗ const { createStorage } = require('redux-storage-middleware')

Named export for creating a storage engine; also ESM only.

StorageMiddlewareConfig

✓ import type { StorageMiddlewareConfig } from 'redux-storage-middleware'

✗ import { StorageMiddlewareConfig } from 'redux-storage-middleware'

TypeScript type import; not a runtime value.

Configures and applies redux-storage-middleware with a localStorage engine and custom serialization.

import storageMiddleware from 'redux-storage-middleware'; import { createStore, applyMiddleware } from 'redux'; const storageEngine = { getItem: (key) => Promise.resolve(localStorage.getItem(key)), setItem: (key, value) => Promise.resolve(localStorage.setItem(key, value)), removeItem: (key) => Promise.resolve(localStorage.removeItem(key)), }; const middleware = storageMiddleware({ engine: storageEngine, key: 'my-app-state', serialize: JSON.stringify, deserialize: JSON.parse, }); const store = createStore(rootReducer, applyMiddleware(middleware));

Debug

Known issues

breakingESM only since v1.0.0; require() will not work.

fix

Use import syntax and ensure your project is ESM or use a dynamic import.

affects: >=1.0.0

gotchaMiddleware must be applied before any other middleware that depends on state being persisted.

fix

Ensure storageMiddleware is first in the middleware chain.

affects: >=0.0.1

gotchaThe storage engine must return Promises; synchronous engines like sync localStorage will cause errors if used directly.

fix

Wrap sync operations in Promise.resolve() or use an async storage library.

affects: >=0.0.1

Errors

Common errors & fixes

Cannot find module 'redux-storage-middleware'

Package not installed or not in node_modules.

fix

Run npm install redux-storage-middleware

The engine must be an object with getItem, setItem, removeItem methods

Provided engine does not implement the required interface.

fix

Ensure the engine object has getItem, setItem, removeItem functions.
