@DecentralisedTech gun.user().create() is essentially the same as SEA.pair(), which is a primitive of Gun, but user.create() provides developers with a familiar username/password interface. If you have a SEA pair, you can log into Gun wherever you are, local or not...

@nicholasoxford

Has anyone seen a work gun + Deno demo?

Is there a way to see how many peers are connected to an app at the moment? And also is there some kind of sync acknowledgment from a peer?

@Lexi:matrix.org JS set not compatible :(
@renji3:matrix.org :clap: @draeder :+1: @rococtz:matrix.org important words I strongly agree with. await gun.user(pubKey).get('epub')
@bresnow WebRTC ~ 6, but non-WebRTC ~ 10K
@Manwe-777 wouldn't you have to know the hash to lookup the login, but you won't know the hash until after login?
@hownowbrowncow_8635:matrix.org it gets cached locally, yes.
@Azarattum @azarattum:matrix.org :clap: @Lexi:matrix.org . Expiry, yupe. Else you'd need to have a 2nd index that you lookup that is a ban list.
lookups in GUN are O(1), so they're efficient.
Glad you're asking for help at 5min!
isn't your .on( getting called with both?
Oh wow, I haven't seen that github issues in years I thought it was closed... had no clue people were responding in it. (At some point... GitHub notifications just stopped/broke).
@Omarabuziad thanks for reminding a Q if it got missed! We're not perfect, so its very much appreciated if anyone just re-asks.
:clap: @bmatusiak @draeder . If you are on a permanent machine, then fs RAD is good enough. If you are on a machine that gets wiped/deleted every X hours, you probably want a backup in case not enough browsers are online.
@SarahKay99 looks correct. :clap: @rococtz:matrix.org . Not sure why not. does npm start 1337 work?
@SamiLaayouni_twitter possibly the login bug... if you hit login 3+ times, does it login?
@useWallie_twitter you should check out @davay42 's cool vue component that does that!
@SarahKay99 the Fireship chat app was public, so anyone can add/update the table, they just can't modify the message itself. With DM, you don't want a public table, so you either (A) have to https://gun.eco/docs/SEA.certify user A can edit user B's table that they both chat on or safer/better (B) "thread" the chats, by saving userA.get(userBpubKey).set(chat); and userB.get(userApubKey).set(chat)then you .map().on(function thread(){ ... on both and pass both into the UI, that you sort. Then later on you'll want to use LEX to paginate the chat (right now this may be a bit buggy... but we're working on some cool new features to make this rock solid).

Thanks so much Mark! I got the server running, the problem was i didnt npm install . as for the chat app issue i will rethink my code. tysm

Azarattum: Gun uses WebRTC AND websockets under the hood. Yes, you really have to implement a heartbeat system where the users who want to be discovered simply register themselves every X seconds/minutes against some list say "I'm online" so others can see they are online

Hi, can someone help me why the onDisconnect() doesn't fire after closing the browser or tab

and also the connected() does not trigger when we reconnect to the server even if we make a change in the data

I guess I don’t understand something. Isn’t there some kind of a built in mechanism for peer discovery?

That's the plan for AXE. Don't know how far it's done already.

Does it just use the list you provide and that’s it?

The list of peers in the GUN constructor? Yes, except if using AXE which is default.

I thought gun uses webRTC under the hood, so shouldn’t the connections information be already available?

WebRTC is used for p2p communication between browsers. For browser ↔️ NodeJS clients websockets are used. Remember to import lib/webrtc.js to enable WebRTC and even then it might not work for the current version. Would be cool if you'd test it and report back!

Does the ack in put comes from a remote peer?

I'm guessing it comes from one or all of the peers set up in the GUN constructor. If it's not properly described on the API could you report back? Extra points for testing and finding out again :-) That's kinda how it works for unstable GUN right now :\

Is there a way to know that an entire database is in sync? Let’s say I have a client making changes. I want to show user a spinner until his changes are successfully propagated through the network. (Or at least to the nearest relay peer)

The latter point is easy. As I said there's the ack callback for that in put(). The former could be done by recording the datetime of the last complete sync. Would that be what you want?

can anyone tell me why i am getting a status 400 with the route /gun

require('dotenv').config()
const express = require('express')
const Gun = require('gun')
const cors = require('cors')

const app = express()

app.use(cors())
app.get('/', (req, res) => {
    return res.status(200).json('success')
})
app.use(Gun.serve)
app.get('*', (req, res) => {
    return res.status(400).json('unsuccessful')
})
Gun({web: app.listen(Number(process.env.PORT), '0.0.0.0'), radisk: true, file: './folder'})

console.log('Server started on port ' + process.env.PORT + ' with /gun')

trying to make my own gun relay with storage saved to disk. but the /gun route always gives me a 400

@draeder

I've finished Gunsafe .. the example CLI might be a little buggy at times, and there appears to be a parsing issue with multiline documents that contain special characters.. but it's a start.

I wrote Carets to make working with multiline objects from the CLI for gunsafe a little less painful than readline and/or stdin by themselves

I’ve seen talks where Mark mentions AXE, but didn’t quite understand how exactly it is supposed to work from a technical (not conceptual) perspective.

3 replies

Also, ideologically, is GUN supposed to be one giant network or each application should implement it’s own network on top of GUN with it’s own rules?

Azarattum: AXE is part of the core of Gun. Some parts are working, some are missing, some are buggy. In the future, Gun is supposed to be a gigantic network with thousands of relays

I guess I am pretty lost, I am new to this end of things. I know alot of peaple that are interested in getting out of the main stream bs, and would be interted in this. But I can not figure out how to set it up so they can down load as an app, or even get it working at all. I have to head to work but if someone wouldbe willing to give me some direction later it would be appreciated

@donlevirobert_gitlab if youre running latest github it has some bugs , might want to try npm instead. Would be nice to know what you tried (as in code), to get an idea of what could be failing.

@Manwe-777 honestly I have tried npm, git hub a few different ones https://www.youtube.com/watch?v=Rc2sIPDrX_k , https://www.youtube.com/watch?v=zvo6jC1OA3Y, https://www.youtube.com/watch?v=J5x3OMXjgMc&t=272s, https://gun.eco/docs/ (that was the most confusing thing to be honest) I trired with firebase, I tried with ste,

@Manwe-777 it have to be me, I really think a walk though to ppl that don't code, or build sites my help alot with getting this more main stream... I have want to help and get this out to my colleagues, that is why I ened up on the form... Honestly this is the second chat form I have every reached out to..

I think the server migration should be theoretically possible cryptography-wise. I guess some clever trick is needed to make this work. Maybe a user can store a public key of the server it currently trusts. So, any changes that violate this rule will be rejected from the network. (Or something along these lines. I really need to think this trough before implementing anything...)

Azarattum

@azarattum:matrix.org

I’m curious, is there a way to tell gun relay what data to cache? Ideally I would want it to store all the data of it’s users, some globally available network cache and maybe parts of data of a user from another server. About the last one: for example user A wants to share access to a document with user B, but they are served by different servers. Both users explicitly agree on this transaction. In this case I want the relay of user B to cache A’s document.

Lexi

@Lexi:matrix.org

[m]

Question is do you also want users to be able to revoke read permissions on that data? Or only future data? The latter is possible however still not easy. But if it's self hosted all that doesn't matter, right?

When you go to use a library you wrote months ago only to find out it doesn't work correctly after npm install... 😭😭😭😭😭

And your local code is broken because you were working adding features... LOL ugh.

Sarah Kay

@SarahKay99

In a DMing app... if User A doesnt copypaste User B's public key into their screen, how can User A and User B share public keys? For example I am User A and I find User B through their alias.

I want to start DMing User B. How does the system facilitate public key sharing between User A and User B without copy pasting?

@amark

@entermonke:matrix.org ipv6 & pubkeys seem roughly same in difficulty to remember. Linkability matters. Iris Web of Trust should let us do "Elon Musk" with 99% score, confidence ratings on/for every name.

@azarattum:matrix.org :clap: @rococtz:matrix.org :clap: @Lexi:matrix.org !
You usually don't want WebRTC to exceed 6 connections. Could look at how many people are subscribed to a particular node in AXE, but that is only for each network hop. Latest github has upgraded put acks to have probabilistic counters of who has saved data. (And yes, they come from other peers, even if not directly connected). Yes, AXE in NodeJS runs by default - this is a good current status of where AXE is at:

@yorreraj they listeners are gun.on('hi', function... and 'byte' not connected/disconnect.
@azdez:matrix.org looks like your * taking higher precedence?

@azarattum:matrix.org :clap: @Lexi:matrix.org that is an excellent explanation!!!

Happy to hop on a call, @draeder has been helping me build AXE in code calls. Feel free to join!
:clap: @rococtz:matrix.org .
Nice diagram. Decentralized is different than Federated. Email is federated. You can build a federated system with decentralized systems, but I'd recommend you stick to fully decentralized. :clap: @draeder :clap: @Lexi:matrix.org :clap: @Manwe-777 .
@entermonke:matrix.org + @fractal:matrix.org :clap: yes @mmalmi ! Iris! :)
@evan-brass:matrix.org , yes WebRTC signaling automatically happens from every peer (even browsers!), join the (see above) calls as we're building the DHT part now!
@ghost~62c3eb896da0373984998ff1 what is wrong?
@harshavardhan282 if you are using GUN for browser, it is pre-built, just use gun/gun.js (don't build it). If React Native, see https://github.com/aethiop/jot tutorial.
@donlevirobert_gitlab :clap: @entermonke:matrix.org :clap: @Manwe-777 . If you're mainstream, why not just use an in-browser app that runs GUN already? There is no need to download/install GUN to use GUN. Using a browser app that uses GUN already helps contribute to the network. Maybe I'm misunderstanding your goals? What are your goals?
@entermonke:matrix.org founder of freenet guy just DMed me last week to talk! I felt so honored. We're discussing to see if we can make locutus interoperably use same messaging system as GUN's.
@azarattum:matrix.org yeah @draeder 's gunsafe pairing system might be an interesting solution for doing trusted remote compute.
Yes, the DHT part will allow peers to select a lexical shard they persistently store data for (until running out of space).
:clap: @Lexi:matrix.org .
@spoggy:matrix.org nice mindmap! Have you seen @davay42 's realtime mindmapping & node system? Its gun-vue & includes tons of other modules. Very advanced.
:clap: @bmatusiak for explaining cryptography stuff. Hey, is anyone able/willing to sponsor @bmatusiak ? Or know companies hiring in cybersecurity you can refer him to?
@quixnix:matrix.org might need to tag typescript people to help you.
@snowycoder:matrix.org I can't tell if gitter is being buggy, or just jumping to chats I replied to last week or not. But you saw how GUN does decentralized discovery and rebalances itself right? (See the twitter link I linked to above, it has a video). You and @Azarattum having similar Qs, I'll try to expand more - let me know!

@SarahKay99 clicking on links (which have the pubkey) is gonna be easiest since that is how pretty much all apps/web work to start. Once people are already in your app tho, you can do indexed searches like @rococtz:matrix.org has demos/links of. So in-app users would search for a name, and you'd show a list of results (maybe Web of Trust score, Iris-style) and people would click on those accounts and "add friend" which underneath would add their pubkey.

HOPE EVERYONE HAD AN AMAZING FOURTH OF JULY!!!!!!!!! :fireworks: :fireworks: :fireworks: :fireworks: :fireworks:

@grantyap

hey guys quick question, is there a way to "construct" the subproperties of a chain just one level deep before returning it?

for example:

{
    "name": "foo",
    "address": {
        "city": "bar",
        "street": {
            // unneeded data
        }
    }
}

here, i'd like to access just the name and address.city

i thought about using load(), but i don't really need to access all the subproperties

or will i have to do separate get() calls to achieve this?

tldr: is there a way to include the resolution of subproperties when using on() or once() on a document?
