I'm trying to write a little peer to peer program using Gun, React and Konva, the general idea being able to see the mouse of the other users on your screen, I can get gun to update using
swarm.map().on(({ name, x, y }: SwarmPeer) => {
console.log(name, x, y);
});but the problem is its super slow at updating. I'm console logging out the x, y of the mouse and I can see that firing rapidly. The console log inside that map.on function is however extremely slow and lags behind by several seconds. I have done the tutorials and managed to successfully get a live update of a textbox (like google docs) which seemed instantaneous and inspired this idea. Is there anything super obvious I might be getting wrong? Thanks in advance :)
// John's computer
onMouseMove(() => {
gun.get('John').get('position').put({ x,y })
})
// Mike's computer
gun.get('John').get('position').on(renderThePosition).map( x => !!x || undefined)If you return
undefined from map, the callback won't be called.
hi there, anyone using the expiry option with SEA.certify? got certs working but they don't seem to expire.
to test, i created a cert set to expire at 100ms from now (Date.now() + 100), copied the resulting certificate, and hardcoded it into { opt: { cert } } when doing a put.
error on my part, or?
heres my code: https://github.com/SuaYoo/gundb-react-express-auth-example/blob/main/server/server.js#L42
in general, would be great to get feedback on what i have so far: https://github.com/SuaYoo/gundb-react-express-auth-example
react + express app with:
- sign up
- sign in
- change password
- update user profile
- multi-tab session syncing
- access control--only allow logged in users to update areas

@smarthug wooooooooah awesome, what graphics are you using? Raw WebGL? Unreal? ThreeJS/Babylon? https://github.com/amark/gun/blob/master/examples/game/space.html is a janky 200LOC multiplayer asteroid-like game. But check out @estebanrfp 's work he has a full metaverse running and syncing on GUN.
@connor-davis :clap: :fire: @rococtz . It should ahve just worked, are you sure? The keypair must be all 4, not just public parts.
@RilDev YAAAAAY its working?? :)
@libensveto_twitter :fire: tweeted!!!
@RilDev I'd argue GUN is more compliant @lmangani:matrix.org because if you do
user.get('name').put(null) it not only overwrites the bytes it synchronizes it on the network, other dweb/blockchain can't do this (its a new log entry) and centralized systems have duplicate copies of the data in different systems not connected by a sync protocol.@connor-davis :clap: :clap: ! :) congrats.
@oscarhilton :wave: !!! what is Konva? :)
Interesting, text editing should be harder to render than mouse movements. Maybe the peer you got connected to was slowing down? Is it slow if you run your own localhost peer?
@adam-12:matrix.org the
null are needed to tombstone the data (so they don't resync), the technique most people use is to "start a fresh new piece of paper" so like having the name of the node hold its year/month/day, then each day (or whatever timeframe) starting a new node by copying the previous values over (but not the nulls).@SuaYoo :wave: :wave: :wave: :) we just did a massive update last month, so it is possible expiry regressed in that time, there is a bug out that I need to fix around multiple pubkeys that maybe relates to it.
Neeeeeeat! Will you add it to https://github.com/amark/gun/wiki/awesome-gun for others to find too? And publish a demo on vercel or github pages or something!! Exciting to see solid profile controls managed!
Hey there everyone! Hope you are all doing well :)
I am currently looking to build a sveltekit app running on netlify using gun.js as an information store. Unfortunately, something isn't quite clicking for me. I cannot seem to get beyond this specific error: https://deploy-preview-2--laughing-austin-64bcf3.netlify.app/
My first thought was that this had something to do with SSR, so I tried disabling that, and it changed nothing. I tried creating the radata folder, also no dice.
Apologies if this is a dumb question, but I am just getting my feet underneath me with frontend development/svelte/gun; any tips or tricks would be greatly appreciated!
All of my code can be seen here: thoward27/thor#2
require('gun/gun') (in memory only) instead? I'm not entirely sure tho. Your app can be hosted on static sites, but WebRTC in browsers :( :( sadly still requires bootstrapping peers, which won't work on Netlify/static hosts.
GUN({rad:false}) and GUN({radisk: false}), both resulted in the same error as before, failure to create the radata folder {"errorType":"Error","errorMessage":"EROFS: read-only file system, mkdir 'radata'","trace":["Error: EROFS: read-only file system, mkdir 'radata'"," at Object.mkdirSync (fs.js:921:3)"," at Store (/var/task/.netlify/functions-internal/__render.js:9271:12)"," at Object.next (/var/task/.netlify/functions-internal/__render.js:9310:48)"," at Object.next (/var/task/.netlify/functions-internal/__render.js:9042:15)"," at Function.onto [as on] (/var/task/.netlify/functions-internal/__render.js:5219:17)"," at Function.Gun2.create (/var/task/.netlify/functions-internal/__render.js:5400:20)"," at new Gun2 (/var/task/.netlify/functions-internal/__render.js:5372:23)"," at Gun2 (/var/task/.netlify/functions-internal/__render.js:5370:20)"," at Object.<anonymous> (/var/task/.netlify/functions-internal/__render.js:15563:33)"," at Module._compile (internal/modules/cjs/loader.js:999:30)"]}
added the example to the wiki, thanks!
is there a way to manually add/trigger an error from gun middleware? i'm using bullet-catcher to verify JWTs, but since it fails silently, i cant tell the client to ask for another JWT. hoping for something like this:
if (isValid(msg)) {
to.next(msg)
} else {
// context.err = 'expired token'
// or
// msg.err = 'expired token'
// or...
// context.throwError('expired token)
}i suppose i can do something like
if (isValid(msg)) {
to.next(msg)
} else {
gun.get(`~${appPubKey}`)
.get('errors')
.get(msg.headers.userPubKey)
.put('invalid token')
}but that feels...weird? since anyone would be able to read this error? still wrapping my head around gun-space
@amark It sends to a remote server that contains the following code:
import Gun from 'gun';
import "gun/nts";
import "gun/lib/radix";
import "gun/lib/radisk";
import "gun/lib/store";
import "gun/lib/rindexed";
const PORT = 8080;
const HOST = "0.0.0.0";
var http = require('http');
var server = http.createServer();
var gun = Gun({ web: server, axe: false });
server.listen(PORT, HOST, () => {
console.log(`Server listening to localhost:${PORT}/gun`);
});This is inside a docker container. The routing and ssl on the server is handled by nginx proxy manager (which runs in another docker container). And as we discussed, it is working fine for data that arrive in realtime. The client app is not able to fetch already existing data from this server.

Warning: AXE alpha became super slow & laggy, now in testing only mode!. So I decided to not import AXE and that got rid of the problem. However, should I import AXE anyways or not? Thanks in advance(By the way, your hair is awesome!)

@SuaYoo
context.on('in', {'@': msg['#'], err: "error!"})
updated the example here to implement marks suggestion if anyones curious: https://github.com/SuaYoo/gundb-react-express-auth-example/pull/1/files
gun will try to pull all the NodeJS modules automatically, try dropping the extra import statements, and see if that changes anything? (If not, then try turning AXE back on). If these last checks don't work then I don't know what is going on, and maybe would need to screenshare or something.@Monknow <3 thanks :) :) :) . AXE in browser is experimental and not necessary, if you remove it tho, you need to add/specify peers
GUN([peer1, peer2, etc.@connor-davis :fire: yay
@rrmckinley:matrix.org nice tip off! Have any connections to him?
@jnfrati we announced before them and are not related to them. AXE is like 40% complete, if you want to help build the last 60% we have quite a few "PANIC" tests we simulate it under to test against. Curious?
@SuaYoo :pray: thank you! Did it work for you too?
@connor-davis Nice, can I tweet about this?
@libensveto_twitter I was there a long time ago. What were you "shilling"?
@Manuel-777 the problem is no other system even comes comparably close to any method, at all :( so something is better than nothing. Luckily, @aethiop built a 3FA method too! https://twitter.com/marknadal/status/1427715775838572545
@mimiza agreeeeeeed, after being gone on legal stuff for the few weeks, I've back been in docs world and then Brave said they'd review my SecureRender proposal. I need to fix this for you, can it be done after SecureRender or no?
