Also I plan to add gun instance override for webrtc.js later so that only people in room (and sharing rooms key) could see the messages. For example pass gunsafe instance to webrtc.js instead of usual gun instance to start communication.
Not sure if that will be useful in upstream, but I will use it for my project

hi folks!
I am trying to make a react chat application using Gun. I have the following code which is fetching the messages.
const fetchMess = useCallback((key) => {
const messages = gun.get(key);
messages.map().on((m) => {
console.log(m);
dispatch({
type: "add",
newMessage: {
name: m.name,
message: m.message,
createdAt: m.date,
key: m.key,
},
});
});
}, []);For some reason, the callback for on is being fired multiple times for every message, the first time I am calling this function. This is messing up the message list, since the dispatch (responsible for changing the state of the message list; from the useReducer hook) is mutating the message list multiple times.
Any work around for this?
if(!m || !m.prop1 || !m.prop2 || !m.prop3) return;or whatever you need to before the dispatch
a debouncing fn would look roughly something like this:
function debounce(func, timeout = 300){
let timer;
return (...args) => {
clearTimeout(timer);
timer = setTimeout(() => { func.apply(this, args); }, timeout);
};
}
function dispatch(x){
console.log(`Processing data ${x}`);
}
const dispatchDebounced= debounce((...args) => dispatch(args));
for(x=10000;x>0;x--){
dispatchDebounced(x) // you should see in console only 'Processing data 1' instead of 10000 :)
}
@draeder: do you mean that Book returning a page and a half is working or the lexical part is working. because i tried a lexical query and it is not returning each object.
gun.get('tests').get({'.': {'>': 'a', '<': 'z'}, '%': 50000}).once().map().once((datas) => {
console.log(datas)
})the above returns nothing even though it should
i don't know why but this works.
gun.get('tests').get({'.': {'>': 'a', '<': 'z'}, '%': 50000}).once(data => console.log(Boolean(data))).map().once((datas) => {
console.log(datas)
})if i console log the first once() for some reason it returns each object/data by itself on the second once() after the map()
Hi does anyone know why I'm getting this error in angular after creating a new user using Gun?
UnhandledPromise rejection: Unexpected non-whitespace character after JSON at position 2 ; Zone: <root> ; Task: null ; Value: SyntaxError: Unexpected non-whitespace character after JSON at position 2The code gives me an error at sea.js file. And it looks like this.
// ideally we can move away from JSON entirely? unlikely due to compatibility issues... oh well.
JSON.parseAsync = JSON.parseAsync || function(t, cb, r) {
var u;
try {
cb(u, JSON.parse(t, r))
} catch (e) {
cb(e)
}
}Can anyone help me with this ?

Gun.chain.promGet = function(key) { let chain = this; return new Promise(resolve=>{ chain.get(key).once(resolve) }) }
// usage after instantiating : let gun = Gun({...})
//either with async
(async()=>{
let results = await gun.get("myapp").promGet("key")
console.log("results",results)
})()
// or with regular promise-then
gun.get("myapp").promGet("key").then(results=>
console.log(results);
})

Hello guys,
I would like to develop a Family tree project using Gun JS. I want to make sure these 3 things can be done.
- Privacy of non-connected nodes
- Privacy of a node
- Privacy of a piece of data in a single node
2 different family tree data need to be separate. Currently all data shows up in developer tools of a browser. Is there a way to keep some data secret from others?
I can’t have all data visible to every family members
