What do you need IndexedDB for?

• azangru 5y ago
  In-browser long-term storage.

    Yeah, but of what? Caching the downloaded file? I wouldn’t think encrypted file links would need long term storage of anything. You receive the link, key exchange is derived from key in link, file is downloaded and decrypted on-the-fly.

      > Yeah, but of what? As far as I understand Google's recommendation for web developers, of anything [0]. Their position is, avoid localStorage because it's synchronous, use indexedDB because it's asynchronous. So anything you would use localStorage for, Google suggests putting into indexedDB instead. I don't remember whether the browser API was expected to get AsyncLocalStorage like the Node API has, or whether that would change Google's recommendations for developers.

        GP’s point is that at first blush it doesn’t seem like the Wormhole app should need any local storage in the first place.

  Wormhole.app uses peer-to-peer transfer to send your files directly from your browser to the recipient, in addition to using cloud hosting. We use WebTorrent behind-the-scenes, so we need random access to the end-to-end encrypted version of the files to satisfy requests from peers. So we try to put the files on disk using Filesystem Access API or IndexedDB, falling back to in-memory if there's not enough storage.
