kandi X-RAY | umbrel Summary

umbrel is a HTML library typically used in Blockchain, Cryptocurrency, Bitcoin, Docker applications. umbrel has no bugs, it has no vulnerabilities and it has medium support. However umbrel has a Non-SPDX License. You can download it from GitHub.
⚠️ Umbrel is currently in beta and is not considered secure. Please see SECURITY.md for more details. This is the master repository of Umbrel and contains the framework for orchestration of all containerized services running on Umbrel OS. It is platform and architecture-agnostic, thus can be used to directly spin up instances of Umbrel without installing the Umbrel OS since all orchestrated services use multi-architecture Docker images. We run it on Raspberry Pis (ARMv8) as a part of Umbrel OS, Ubuntu (x64) for testnet.getumbrel.com and macOS (x64) for local development.

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();

Vulnerabilities

Install umbrel

If you're looking to run Umbrel on:.
A Raspberry Pi 4 with at least 4GB RAM (recommended) - Download Umbrel OS
Anything else (not recommended as it's experimental at the moment) - Install Umbrel
Umbrel OS for Raspberry Pi is the easiest and the recommended way to run Umbrel. If you don't have a Raspberry Pi, you can manually install Umbrel on any hardware running a Linux-based operating system such as Ubuntu, Debian, etc by following the instructions below, but please note it's not the recommended way to run Umbrel as it's still very experimental.
Make sure your User ID is 1000 (verify it by running id -u) and ensure that your account is correctly permissioned to use docker.
4GB RAM and 600GB+ free space (for mainnet)
Docker
Python 3.0+
Docker Compose
fswatch, jq, rsync, curl, git (sudo apt-get install fswatch jq rsync curl git)
Run this in an empty directory where you want to install Umbrel. If using an external storage such as an SSD or HDD, run this inside an empty directory on that drive.
