Setting Cron Triggers
Set a Cron Trigger for your Worker.
addEventListener('scheduled', event => {
event.waitUntil(triggerEvent(event.scheduledTime));
});
async function triggerEvent(scheduledTime) {
// Fetch some data
// Update API
console.log('cron processed');
}
Setting Cron Triggers in Wrangler
If you are deploying with Wrangler, set the cron syntax (once per hour as shown below) by adding this to your wrangler.toml
file:
name = "worker"
# ...
[triggers]
crons = ["0 * * * *"]
You also can set a different Cron Trigger for each environment in your wrangler.toml
. You need to put the [triggers]
table under your chosen environment. For example:
[env.dev.triggers]
crons = ["0 * * * *"]
