What is the correct way to make async calls in NodeJs app


I am using webservice with Node environment on render.com, I am making an async call in a cron job, like the below, the deploy fails after some time, am I doing this correctly ?

My Code in app.js

const cron = require("node-cron");

// Define the task to be run on a cron schedule
const task = () => {
  console.log("Cron job running at:", new Date().toLocaleString());
  // Add your cron job logic here

// Schedule the task to run every minute
cron.schedule("* * * * *", task);

// Log a message when the app starts
console.log("Cron job app started.");

function resolveAfter2Seconds() {
  return new Promise((resolve) => {
    setTimeout(() => {
    }, 2000);

async function asyncCall() {
  const result = await resolveAfter2Seconds();
  // Expected output: "resolved"

App Settings are as follows:
Environment: Node
Build command: npm install
Start command: npm start


  "name": "myapp",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  "author": "",
  "license": "ISC",
  "dependencies": {
    "dayjs": "^1.11.0",
    "dotenv": "^16.0.0",
    "express": "^4.18.2",
    "mongodb": "^4.3.1",
    "mongoose": "^7.0.1",
    "node-cron": "^3.0.2",
    "nodemon": "^2.0.21",
    "onesignal-node": "^3.3.0"


Web Services are for web servers, e.g. Express, etc.

If you want to cron something, there are Cron Jobs. Or if you want to roll your own, Background Workers
