Force usage of a particular driver or drivers, if available.

this.$setStorageDriver(localforage.LOCALSTORAGE)

By default, localForage selects backend drivers for the datastore in this order:

1. IndexedDB
2. WebSQL
3. localStorage

If you would like to force usage of a particular driver you can use $setStorageDriver() with one or more of the following parameters.

localforage.INDEXEDDB

localforage.WEBSQL

localforage.LOCALSTORAGE

Set and persist localForage options.

this.$storageConfig({
    driver: localforage.LOCALSTORAGE,
    name: 'Name-of-localStorage'
});

This must be called before any other calls to localForage are made, but can be called after localForage is loaded.

driver

The preferred driver(s) to use. Same format as what is passed to setStorageDriver(), above. Default: [localforage.INDEXEDDB, localforage.WEBSQL, localforage.LOCALSTORAGE]

name

The name of the database. May appear during storage limit prompts. Useful to use the name of your app here. In localStorage, this is used as a key prefix for all keys stored in localStorage. Default: 'localforage'

size

The size of the database in bytes. Used only in WebSQL for now. Default: 4980736

storeName

The name of the datastore. In IndexedDB this is the dataStore, in WebSQL this is the name of the key/value table in the database. Must be alphanumeric, with underscores. Any non-alphanumeric characters will be converted to underscores. Default: 'keyvaluepairs'

version

The version of your database. May be used for upgrades in the future; currently unused. Default: 1.0

description

A description of the database, essentially for developer usage. Default: ''
