Using skynet on a gun relay peer

[davay42]

Hi! I see you updating the code recently. It's very interesting to try zenbase again (i've experimented with it about a year ago and it was too slow to use zenbase without a relay)

Today I've tried to use zenbase on a node gun relay server. I think it's a nice way to have a no-store free tier exchangeable relays that store and retrieve data from skynet.

Here's my server init script https://github.com/DeFUCC/gun-vue/blob/master/relay/server.js - it's a one-liner gun relay for my https://github.com/defucc/gun-vue project.

It loads and seems to work fine. But after the server restarts it doesn't get previously saved data back. So no permanent storage is achieved. May be I'm doing something wrong?

Can you please help me find the right way to use zenbase with node (v.16, so ES module syntax is OK there).

If you have a relay server, why would you need Zenbase?

Honestly I don't know if they're compatible or not, we'd have to have a chat with Mark about how gun's storage adapters work. If you set the debug flag to true, Zenbase will print logs which can help you determine whether it's being used or not. This is what I've done which works in Nodejs. I'll update the readme some more after I do some more testing

const GUN = require('gun');
const Zenbase = require("zenbase");

const gun = new GUN({
    localStorage: false,
    secret: "YOUR_SECRET_HERE",
    portal: "https://siasky.net",
    debug: false,
    until: 2*1000
})

gun.get('hello').put({ name: "world" });
// Get data into gun. This will pull from memory, then localStorage (disabled), then Skynet
gun.get('hello').on(data => { 
  hello_world = data['name']
  console.log("hello: " + hello_world)
})

There's a plenty on services like Glitch.com or Heroku, where you can run a node.js server for free, but with very limited storage. I imagine using these interchangeable relays sharing the same Skynet data to have both the speed and the storage capacity. In my experiments with debug=true the put and get works in a server app session. But after a restart it doesn't get previously saved data back. Glad you're back to the project! 👏

I think I may have introduced a bug. Working on it. In the mean time, try the 2.0.0 version and see if that makes a difference. You may wanna try Zenbase by itself again. It used to be slow before this fix #1

So... not a bug. Looks like something in Gun prevents Zenbase from working as expected with Nodejs. I'll have to work on that

Hello fluffy9 and davay42,

I found errors in zenbase-2.1.6 see here: ISSUES #5
!!!Please read link!!!

I looked at the code from "SkynetLabs/gundb-relay" / also looked at "SkynetLabs/skynet-js" and "SkynetLabs/nodejs-skynet"!
I also looked through the documentation of sdk skynet and there you can read under SkyDB ( Link: https://sdk.skynetlabs.com/#skydb ):

"These functions have only been implemented for Browser JS at the moment."

!!!WARNING!!! VERY IMPORTANT !!!!
This means that skydb the commands "client.db.getJSON(publicKey, dataKey);" and "client.db.setJSON(privateKey, dataKey, json);" is only implemented in the browser version (skynet-js) and NOT in the NODEJS version (nodejs-skynet)!!!!

The "gundb-relay" is a NODEJS version, so it shouldn't work at the moment!!!

You should also define how the "gundb-relay" should work!

In Monet, only the "gundb-relay" works as a gun server, but without zenbase having implemented a skynet-skdb in nodejs-version, and because the zenbase module is loaded, gundb does not use radisk (no radata) used!

In order for the gundb server to keep the data after a restart, radisk (radata) must work!
Or SkyDB must first be implemented in the NODEJS version "SkynetLabs/nodejs-skynet", then it could work, maybe even without radisk!

If SkyDB is implemented, there is certainly a possibility that zenbase and radisk will work together!
I'll see if I can find another solution before implementing SkyDB in NODEJS!

gundb works as it should!

With friendly greetings
