Is IndexedDB deprecated?

Is IndexedDB better than LocalStorage?

LocalStorage is slightly faster than IndexedDB in all browsers (disregarding the crashes). IndexedDB is not significantly slower when run in a web worker, and never blocks the DOM that way.

How long does IndexedDB last?

IndexedDB data belong to a type of temporary. So these data can be wiped out at any time. These data size/lifetime are managed by very new Quota Management API.

When should I use IndexedDB?

IndexedDB is a newer facility for storing large amounts of data in the browser. You can use it to store data of any JavaScript type, such as an object or array, without having to serialize it. All requests against the database are asynchronous, so you get a callback when the request is completed.

Is IndexedDB permanent?

Note: After introducing Storage API, the "permanent" folder can be considered obsolete; the "permanent" folder only stores IndexedDB persistent-type databases.
