Redux Persist adapter for IndexedDB storage

Storage adapter to use IndexedDB via idb v3 with redux-persist ripped from idb v3 docs > Examples section

Installation

Using npm:

1npm install --save @piotr-cz/redux-persist-idb-storage

or Yarn:

1yarn add @piotr-cz/redux-persist-idb-storage

Requirements

• Promise support/ polyfill

Setup

Import the storage and include it in persistConfig when creating Redux store:

1// configureStore.js
2
3import createIdbStorage from '@piotr-cz/redux-persist-idb-storage'
4
5const persistConfig = {
6  key: 'root',
7  storage: createIdbStorage({name: 'myApp', storeName: 'keyval'}),
8  serialize: false, // Data serialization is not required and disabling it allows you to inspect storage value in DevTools; Available since redux-persist@5.4.0
9  deserialize: false, // Required to bear same value as `serialize` since redux-persist@6.0
10}
11
12// ...

Server-Side Rendering

When using Server-Side Rendering (SSR), indexedDB won't be available in the environment.

In this case you may use feature detection with a fallback to use default redux-persist storage (which resolves to noop functions):

1// configureStore.js
2
3// Redux Persist storage
4import defaultStorage from 'redux-persist/lib/storage'
5
6// IndexedDB storage
7import createIdbStorage from '@piotr-cz/redux-persist-idb-storage/src'
8
9const persistConfig = {
10  key: 'root',
11  storage: globalThis.indexedDB ? createIdbStorage({name: 'myApp', storeName: 'keyval'}) : defaultStorage,
12  serialize: false, 
13}

Options

See idb API

• name (optional): IndexedDB Database name. Defaults to 'keyval-store'.
• storeName (optional): IndexedDB Store name. Defaults to 'keyval'.
• version (optional): Schema version. Defaults to 1.
• upgradeCallback (optional): Defaults to upgradeDb => upgradeDb.createObjectStore(options.storeName).

Notes

• idb dependency is locked to version ^3.0.0 as 4+ uses proxies which are not supported in older browsers
