I'm trying to create an api that returns a random song of the day. I'm trying to schedule the randomize function to run once a day to pick a new song for that day. I'm using node-cron to do this. This function is running way more than once a day, however. It appears to be running more like once an hour, but I'm not certain how often its running. The api is hosted on Heroku if that makes any difference.
const cron = require('node-cron');
let usedSongs = [];
let use;
function randomize() {
if(usedSongs.length === 169) {
usedSongs = [];
};
let test = Math.round(Math.random(0,1) * 169);
usedSongs.includes(test) ? randomize() : use = String(test);
usedSongs.push(test)
};
randomize();
cron.schedule('0 0 0 * * *', () => {
randomize();
}, {scheduled: true,
timezone: 'America/New_York'
});
You appear to be calling randomize() twice - once just after the method definition (which will run probably every time the server starts(?), and again inside the scheduler - which should fire once per day as expected.
function randomize() {
if(usedSongs.length === 169) {
usedSongs = [];
};
let test = Math.round(Math.random(0,1) * 169);
usedSongs.includes(test) ? randomize() : use = String(test);
usedSongs.push(test)
};
randomize(); <<<<<<<<<<<<<<<<<<
cron.schedule('0 0 0 * * *', () => {
randomize(); <<<<<<<<<<<<<<<<<
}, {scheduled: true,
timezone: 'America/New_York'
});
