[unstorage] Sync local data to server

[pwFoo]

Hi,
I know the http driver and found a good article about:
https://logsnag.com/blog/mastering-unstorage-building-data-sync-setup

Looks like remote storage instead of local storage with http driver? Anyone played around with local stored data and websocket sync / event listeners for partial sync to remote peers?
If there is a code base I would be interested to take a look.

To describe a setup I have in mind:
Create a decentralized database with unstorage. Users based on crypto key pair and each user have write permission to own database / unstorage base prefixed by pub key string.

1. If I understand how unstorage mounts work foreign data could be mounted i.e. with http driver, but I think it would need a custom driver (websocket? webrtc? ...) with watch() support to subscribe to remote changes.
2. Local (users own) data need to be synced to server too. Maybe implemented with a simple watch() callback to trigger pushing changed data to avoid dependencies in the locally used driver.

I'm not familiar with TS, but would be interested to build that driver and functionality with vanilla JS.
Maybe someone is working an a similiar feature or have some hints how this can be implemented appropriately for unstorage.

Hi @pi0,

I try to sync remote database with local unstorage and need to watch (remote) changes.
First idea was a simple wrapper for pull / push data via websocket.

But with unstorage mount in mind I would love to mount remote unstorage (sub)instance(s). I know http driver, but looks like it not supports watch? And I would prefer local caching / saving of remote data.

Do you have a hint which could be a good / simple way ti implement it

1. Simple sub-instance with a wrapper to get / set remote data i.e. with a websocket or webrtc connection
2. Custom driver (extension) with websocket / webrtc pub-sub
3. ?

Share data between clients is a needed core feature for my project.
