I'm currently using https://github.com/pixtron/bybit-api/tree/master
and what im trying to do looks like this:
const {RestClient} = require('#pxtrn/bybit-api');
const API_KEY = 'xxx';
const PRIVATE_KEY = 'yyy';
const client = new RestClient(API_KEY, PRIVATE_KEY);
client.getPosition({symbol: 'BTCUSD'})
.then(msg => {
let btcPositionCheck = msg.result.size;
if (btcPositionCheck == 0) {
console.log("empty")
} else {
let btcPositionSize = btcPositionCheck;
let btcPositionSide = msg.result.side;
}
})
.catch(err => {
console.error(err);
});
client.getPosition({symbol: 'ETHUSD'})
.then(msg => {
let ethPositionCheck = msg.result.size;
if (ethPositionCheck == 0) {
console.log("empty")
} else {
let ethPositionSize = ethPositionCheck;
let ethPositionSide = msg.result.side;
}
})
.catch(err => {
console.error(err);
});
console.log(btcPositionSize + ' ' + ethPositionSize)
returning me the following error:
ReferenceError: btcPositionSize is not defined
simply because im out of scope, I'm aware. however, I'm unsure how to approach rewriting the following to better allow me to construct what I need. (I need to call getPosition for the 3 different assets as well and take the variables from each call to use later in my code.) if that makes any sense. help would be greatly appreciated
edit:
async function getPosition({symbol: BTCUSD}) {
try {
let btcPositionCheck = msg.result.size;
} catch(error) {
return null;
}
}
im trying to rewrite it but im unsure how
Once you get into asynchronous context, you need to stay in asynchronous context to get values. In your case, there are promises to be resolved, you can await them and then print.
Also you need to make sure that your variables are in valid scope
const {RestClient} = require('#pxtrn/bybit-api');
const API_KEY = 'xxx';
const PRIVATE_KEY = 'yyy';
const client = new RestClient(API_KEY, PRIVATE_KEY);
async function doItAll() {
let btcPositionCheck;
let ethPositionCheck;
await client.getPosition({symbol: 'BTCUSD'})
.then(msg => {
btcPositionCheck = msg.result.size;
if (btcPositionCheck == 0) {
console.log("empty")
} else {
let btcPositionSize = btcPositionCheck;
let btcPositionSide = msg.result.side;
}
})
.catch(err => {
console.error(err);
});
await client.getPosition({symbol: 'ETHUSD'})
.then(msg => {
ethPositionCheck = msg.result.size;
if (ethPositionCheck == 0) {
console.log("empty")
} else {
let ethPositionSize = ethPositionCheck;
let ethPositionSide = msg.result.side;
}
})
.catch(err => {
console.error(err);
});
console.log(btcPositionSize + ' ' + ethPositionSize)
}
Note that nicer way is to await promises into value, which means it can look like that (to use await, it needs to be in an async function)
const msg = await client.getPosition({symbol: 'BTCUSD'})
btcPositionCheck = msg.result.size;
if (btcPositionCheck == 0) {
console.log("empty")
} else {
let btcPositionSize = btcPositionCheck;
let btcPositionSide = msg.result.side;
}

I am making a function for firebase cloud functions, I want a function to be called every time a new document is created in "posts". I want this function to perform the tasks that I put inside the "onCeatePost" function.
The problem I have is that I'm not sure if this is the correct way to structure such a function.
In several firebase examples I have seen that it is always called return _; or return null; at the end of a task, but I don't know how to structure the function so that all the tasks are carried out, could someone help me to restructure my function or tell me what is wrong please.
There are several if statements in the function, if the created publication does not comply with them, I would like it to skip them but continue with the other tasks that I put inside the function.
I don't know if it's too much to ask, but I'm new to this language and I haven't been able to find the answer I'm looking for. Thank you!

You'll find below the adapted code (untested) with 4 corrections.
Here are explanations for the two most important ones:
(Correction 2) In a transaction you need to use the transaction's update() method and not the "standard one"
(Correction 4) When all the asynchronous work is complete you need to return a value or a Promise. See this documntation page for more details.
exports.onPostCreate = functions.firestore
.document('/posts/{postId}')
.onCreate(async (snap) => {
const post = snap.data();
if (post) {
try {
const topic = post.topic;
const contentForFeed = post.contentForFeed;
const uid = post.uid;
const previous = post.prev;
await db
.collection('users')
.doc(uid)
.update({

}
if (contentForFeed == true) {
const userPath = db.collection('users').doc(uid);

My program in a nutshell. If the trigger word is detected in the message, my application creates invoices.
The issue: Multiple calls to the trigger function. All of the requests to the API are simultaneous. This causes my data to have problems.
I have added the async and await to wait for the trigger function to complete. But it seems my calls are still being called all together.

I have used async/await and promises.
When multiple calls are made. The await and promises are still being called at the same time. Not sure what else to look at? any suggestions please. I have spent a week on this.
I'm trying to make a web3 wallet with Moralis with Fasitify in back and VueJS in front.
(I would like to say that I already do this in web client (vuejs) and everything works well!)
In my back, I fetch all the asset from user. It works, I get them all well and I can send them back to the front
But I need to process/sort the data to recover only part of it and send it to the front to avoid doing too much treatment at the front and reduce your workload.
I do that :
*handlers/token.js*
const getTokenBalances = async () => {
let userTokens;
const options = {
chain: "bsc",
address: "0x935A438C29bd810c9aBa2F3Df5144d2dF4F3c0A0",
};
userTokens = await Moralis.Web3API.account.getTokenBalances(options);
return userTokens;
};
and if I return userTokens, I had it in Postman. But now, I do something like :
const getTokenBalances = async (tokens) => {
let userTokens;
let userBalances = [];
const options = {
chain: "bsc",
address: "0x935A438C29bd810c9aBa2F3Df5144d2dF4F3c0A0",
};
userTokens = await Moralis.Web3API.account.getTokenBalances(options);
userTokens.forEach((token) => {
if (
!token.name.match(/^.*\.io/) &&
!token.name.match(/^.*\.IO/) &&
!token.name.match(/^.*\.net/) &&
!token.name.match(/^.*\.Net/) &&
!token.name.match(/^.*\.com/) &&
!token.name.match(/^.*\.org/)
) {
getTokenPair(token).then((value) => {
if (value > 2) {
checkTokenPrice(token).then((price) => {
if (price > 0.001) {
userBalances.push(token);
}
});
}
});
}
});
userBalances.sort((a, b) => {
return b.total_value_usd - a.total_value_usd;
});
return userBalances;
};
userBalances its always empty in my response in Postman (And I don't understand why ?)
The getTokenPair function :
const getTokenPair = async (token) => {
const BNBTokenAddress = "0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"; //BNB
const options = {
token0_address: token.token_address,
token1_address: BNBTokenAddress,
exchange: "pancakeswapv2",
chain: "bsc",
};
try {
const pairAddress = await Moralis.Web3API.defi.getPairAddress(options);
let amount = 0;
//console.log("token pairAddress : " + pairAddress.pairAddress);
if (pairAddress.token1.symbol === "BUSD") {
try {
let reserve = await getPairReserves(pairAddress.pairAddress);
amount += reserve / 10 ** 18;
} catch (err) {
console.log("error getReservesBUSD : " + err);
}
}
if (pairAddress.token1.symbol === "WBNB") {
try {
let reserve = await getPairReserves(pairAddress.pairAddress);
amount += reserve / 10 ** 18;
} catch (err) {
console.log("error getReservesWBNB : " + err);
}
}
//console.log("amount : " + amount)
return amount;
} catch (err) {
console.log("error getPair : " + err);
}
};
and the checkTokenPrice function :
const checkTokenPrice = async (token) => {
let price;
const options = {
address: token.token_address,
chain: "bsc",
exchange: "PancakeSwapv2",
};
try {
const priceToken = await Moralis.Web3API.token.getTokenPrice(options);
price = priceToken.usdPrice.toFixed(7);
token.price = priceToken.usdPrice.toFixed(7);
token.balance = insertDecimal(token.balance, token.decimals);
token.total_value_usd = (token.balance * token.price).toFixed(2);
return price;
} catch (err) {
console.log("error tokenPrice : " + err);
}
};
They are await method in all the function I use so maybe there is a connection.
Thanks for you help !
**** EDIT *****
I solve my problem like this :
const getTokenBalances = async () => {
let userTokens;
let userBalances = [];
const options = {
chain: "bsc",
address: "0x935A438C29bd810c9aBa2F3Df5144d2dF4F3c0A0",
};
userTokens = await Moralis.Web3API.account.getTokenBalances(options);
for (token of userTokens) {
if (
!token.name.match(/^.*\.io/) &&
!token.name.match(/^.*\.IO/) &&
!token.name.match(/^.*\.net/) &&
!token.name.match(/^.*\.Net/) &&
!token.name.match(/^.*\.com/) &&
!token.name.match(/^.*\.org/)
) {
let value = await getTokenPair(token);
if(value > 2) {
let price = await checkTokenPrice(token);
if (price > 0.001) {
userBalances.push(token);
}
}
}
}
return userBalances;
};
Thanks for the help ! ;)
I am wondering if this transaction is even valid and actually ensuring quantity is being the most up to date.
async function deductQuantity(orders: [Order]) : Promise<boolean> {
try {
let document = await admin.firestore().collection("MenuItems")
orders.forEach(async (order)=> {
let itemDoc = (await document.where(`item.catalogType`, "==", order.catalogType).where(`item.id`, "==", order.item.id))
let get = await itemDoc.get()
get.forEach(async a=> {
const pp = document.doc(a.id)
await admin.firestore().runTransaction(async (t)=> {
const mostRecentDoc = await t.get(pp)
const data = await mostRecentDoc.data()
if (data == undefined){
return
}
const newQuantity = data.item.quantity - order.quantity
await t.update(pp, {[`item.quantity`] : newQuantity})
})
})
})
return true
} catch (error) {
console.log("dum: " + error)
return false
}
}
the part where I do let get = await itemDoc.get(), and get.ForEach, is kind of unnecessary because I know, that it will only return one document that matches the query field, but I need to forEach it in order to get the child component\s. Anyways, is it a valid transaction?
I hav two types of variables that I am trying to use in my code and I am struggling to make them not come back as undefined.
const destinationData = collectionData.doc('india');
let travelData = destinationData.get()
.then(doc => {
if (!doc.exists) {
return res.status(404).send(msgNotFound);
} else {
return doc.data();
}
})
console.log(travelData.name);
const passportData = collectionData.doc('australia');
let passportCountry = passportData.get('countryCode');
console.log(passportCountry);
