node js time delay code example

Example 1: node sleep

// one liner
await new Promise(resolve => setTimeout(resolve, 5000));

// or re-usable `sleep` function:
async function init() {
  console.log(1);
  await sleep(1000);
  console.log(2);
}

function sleep(ms) {
  return new Promise((resolve) => {
    setTimeout(resolve, ms);
  });
}

Example 2: node scripts delay

"scripts": {  "test:system": "npm-run-all build -p -r serve test",  "build": "webpack",  "serve": "serve -p 8000",  "test": "wait-on http://localhost:8001 && npm run test:codecept",  "test:codecept": "codecept",}
