"usage" : "integers only, warning: NaN === 0"

import sleep from 'sleep-atomic';
const sleepSeconds = process.env.SLEEP_SECONDS || 10;
sleep(sleepSeconds * 1000);

import { sleep: sleepWithLog } from 'sleep-atomic';
const sleepSeconds = process.env.SLEEP_SECONDS || 10;
sleep(sleepSeconds * 1000);

./server.js is executable. Raise an issue if you'd like, I can enable global install & set logs behind a flag so no output for plain calls.

"functions" : "in case you'd like to copy paste, avoid the import."
