library0.9.2jsnpmunverified

A volatile in-memory storage driver for localForage, designed for unit-testing and fallback scenarios where no persistent storage is available. Data is lost on page reload. Version 0.9.2 requires localForage >=1.4.0. Works consistently with serialization, so retrieved objects are not mutated. Lightweight and simple, with no native dependencies.

Verified usage

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

memoryStorageDriver
✓ import memoryStorageDriver from 'localforage-memoryStorageDriver'
✗ const memoryStorageDriver = require('localforage-memoryStorageDriver')
ESM default export. CommonJS require works in Node but may cause issues with bundlers.
_driver
✓ memoryStorageDriver._driver
✗ memoryStorageDriver.driver
The driver identifier is accessed via the _driver property.
defineDriver
✓ localforage.defineDriver(memoryStorageDriver)
✗ localforage.defineDriver(memoryStorageDriver._driver)
Pass the driver object, not the driver string.

Shows how to define and set the memory driver, then set and get an item.

import localforage from 'localforage'; import memoryStorageDriver from 'localforage-memoryStorageDriver'; localforage.defineDriver(memoryStorageDriver).then(() => { return localforage.setDriver(memoryStorageDriver._driver); }).then(() => { return localforage.setItem('key', 'value'); }).then(() => { return localforage.getItem('key'); }).then(value => { console.log(value); // 'value' });
