QUESTION

Why on printing I get value of null from API call in Loop

Asked 2022-Apr-16 at 03:06

COIN LIST is an array of crypto coins(["BTCUSDT",...]). I try to get the price using getPriceAction and RSI from getRSI and these two functions are working when I try to console DATA. But when I try to print the response after the completion of the loop. It prints the empty array and the length is 0 of this array. I want to store the DATA object (consisting of SYMBOL, closing price and RSI) as an element in the response array

 import { COIN_LIST } from "./COIN_LIST.js";
    import { getPriceAction } from "./PRICE_ACTION.js";
    import { getRSI } from "./RSI.js";

async function main() {
  try {
    let response = await [];
    await COIN_LIST.forEach((element, i) => {
      setTimeout(() => {
        let data = { symbol: element };
        getPriceAction(element, "4h").then((res) => {
          data.closingPrice = res;
          getRSI(res).then((res) => {
            data.RSI = res.reverse();
            data.closingPrice = data.closingPrice.reverse();
            response.push(data);
            console.log(data)
          });
        });
      }, i * 1000);
    });
    console.log(response);
  } catch (error) {
    console.log(error.message);
  }
}
main();

After the completion of the loop, the promises didn't get resolved yet, that's why it print an empty array. One way to achieve what you need is using await for(...), or wait for all promises to be resolved, and then print the results.

import { COIN_LIST } from "./COIN_LIST.js";
import { getPriceAction } from "./PRICE_ACTION.js";
import { getRSI } from "./RSI.js";

async function main() {
  try {
    let response = []; //---> don't need that `await`
    const promises = []; //---> array of promises
    COIN_LIST.forEach((element, i) => {
      setTimeout(() => {
        let data = { symbol: element };
        const promise = getPriceAction(element, "4h").then((res) => {
          data.closingPrice = res;
          getRSI(res).then((res) => {
            data.RSI = res.reverse();
            data.closingPrice = data.closingPrice.reverse();
            response.push(data);
            console.log(data)
          });
        });
        promises.push(promise) //---> save the reference to a promise
      }, i * 1000);
    });
    await Promise.all(promises) //---> await for all promises to be resolved, then print the result
    console.log(response);
  } catch (error) {
    console.log(error.message);
  }
}
main();
