Prerequisites

• I am running the latest code. Mention the version if possible as well.
• I carefully followed the README.md.
• I searched using keywords relevant to my issue to make sure that I am creating a new issue that is not already open (or closed).
• I reviewed the Discussions, and have a new and useful enhancement to share.

Feature Description

As explained in #10945 , some users may want to store more than 5MB of data in browser.

Compressed localStorage is not a scalable solution because it only raise the limit to x4 or x5, but no more.

IndexedDB is preferable in this situation, because there is no hard limit for storage space.

Motivation

N/A

Possible Implementation

A lightweight implementation using one of the libraries on npm.

[lukestanley]

The localForage library wraps IndexedDB, WebSQL, or localStorage with automatic storage backend selection, preferring IndexedDB then localStorage (based on availability).
If someone is to add an extra frontend dependency, one that can automatically switch between available storage options may be better.

localForage is key-value so it may not be very flexible. I did end up using dexie instead.

Closing this now as it's implemented in #11792
