How can I setinterval with Nodej.s for a specific time of day?-CodePudding

I have the following function that runs every hour but I would like it to run once per day at 3 AM:

setInterval(async () => {
    await updateData();
}, 1000 * 60 * 30);

How can I achieve this?

CodePudding user response：

setInterval doesn't have this functionality directly. You could play around with date math to make this happen, but honestly, the easiest approach would probably be to use a thrid-party that does this for you, like node-cron.

First, you'd need to install it:

npm install node-cron

Then, in your code:

cron = require('node-cron'); 
cron.schedule('0 3 * * *', async () => {
    await updateData();
});
