node-schedule should run every 1 hour in node js

Question

I have created crone job for every minute

import * as schedule from "node-schedule"

schedule.scheduleJob('* * * * *', async () => {
            console.log("running every minute")
        });

the above working perfectly for every minute. similarly I have task which has to execute for every hour. I tried like below

schedule.scheduleJob('0 0 */1 * *', async () => {
            console.log("running every minute")
        });

But unfortunately its not working every hour as expected. Is there any thing I'm missing

Also not sure if you are running it in the cloud but make sure your server didn’t go to sleep either. — alec wilson, Feb 10 '21 at 15:35
@alecwilson sometimes I may restart my server for new changes to apply using pm2, how to rectify without restart. — change need, Feb 10 '21 at 15:48
I’m not really sure, you’d have to do some research into that — alec wilson, Feb 10 '21 at 16:46

i think you want "0 */1 * * *". Also you can use this great website to make sure your crontab is correct: https://crontab.guru/

based on node-schedule the third * is hour

*    *    *    *    *    *
┬    ┬    ┬    ┬    ┬    ┬
│    │    │    │    │    │
│    │    │    │    │    └ day of week (0 - 7) (0 or 7 is Sun)
│    │    │    │    └───── month (1 - 12)
│    │    │    └────────── day of month (1 - 31)
│    │    └─────────────── hour (0 - 23)
│    └──────────────────── minute (0 - 59)
└───────────────────────── second (0 - 59, OPTIONAL)

for every one hour just try

schedule.scheduleJob('0 0 */1 * * *', async () => {
        console.log("running every minute")
 });

You should wirte the cron string completely with length of 6 like "0 0 */1 * * *", because it is parsed backwards by schedule.

For every Hour it should be :

schedule.scheduleJob('0 0 */1 * * *', async () => {
     console.log("running every hour")
 });
