I need to read a promise and do things with the data in the promise object but I am not sure how to work with it.
Below is the function I am using to initially pull the data:
export async function getBalance(coin, walletId) {
const req_url = process.env.NEXT_PUBLIC_FIREBLOCKS_SERVER + "/get_balance";
return fetch(req_url, {
method: 'POST',
headers: {
Accept: "application/json",
"Content-Type": "application/json",
'Access-Control-Allow-Origin': '*'
},
body: JSON.stringify({
id: walletId,
asset: coin,
})
}).then(response => response.json())
.then(data => data.balance)
.then((balance) => {
console.log('balance for ' + walletId + ': ' + balance)
return balance
}).catch(error => {
console.log(error)
})
}
Then I am placing the data into a Map, like below:
export function getAllBalances(coin, wallets) {
let balances = new Map()
for(const element of wallets) {
balances.set(element.id, getBalance(coin, element.id));
}
return balances;
}
Everything works out smoothly and it produces the Map below:
I need the values in the promise (i.e. 0, 0.0001, etc.) how do I extract them?
Updated with the Fix
Adding async and pulling out the values a little more in the getAllBalances function helped, see the revised function below:
export async function getAllBalances(coin, wallets) {
let balances = new Map()
console.log("getting all balances")
console.log(wallets)
for(const element of wallets) {
console.log(element.id)
await getBalance(coin, element.id).then(
(balance) => {
console.log(balance)
balances.set(element.id, balance)
}
)
}
console.log(balances)
return balances;
}
