localforage-memoryStorageDriver

A volatile, in memory storage driver for 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 v1.4.0+

Installation

npm i localforage-memoryStorageDriver

Example

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();
})
