localforage-memoryStorageDriver

=================================

[![npm](https://img.shields.io/npm/dm/localforage-memoryStorageDriver.svg)](https://www.npmjs.com/package/localforage-memoryStorageDriver)

A **volatile**, in memory storage driver for [localForage](https://github.com/mozilla/localForage).

**The stored data are lost after a page reload.**

Originally designed for unit-testing (especially SPAs) and as a fallback for environmets without any storage APIs.

This driver serializes the stored items, so that

* it works consistently compared to the "native" localForage driver

* modifications of retrieved (complex) objects do not affect the stored items.

## Requirements

* [localForage](https://github.com/mozilla/localForage) v1.4.0+

## Installation

`npm i localforage-memoryStorageDriver`

## Example

[jsfiddle](https://jsfiddle.net/dp2dzyL9/)

```js

localforage.defineDriver(memoryStorageDriver).then(function() {

  return localforage.setDriver(memoryStorageDriver._driver);

}).then(function() {

  console.log('Active driver: ' + localforage.driver());

  return localforage.setItem('test1', 'value1');

}).then(function() {

  console.log('setItem(\'test1\', \'value1\')');

  return localforage.getItem('test1');

}).then(function(value) {

  console.log('getItem(\'test1\') => ' + value);

  return localforage.clear();

})

```
