Cron

A cron runs backend logic on a schedule: send a daily report, clean expired sessions every hour, sync data every 5 minutes...

Create a cron

In the Explorer, right-click and pick New > Cron. Its graph starts from the Cron Input node, which fires at each scheduled time. Wire your logic after it: database nodes, Fetch, backend functions...

Crons run on the server, like routes. They can use any backend node.

Schedule

Select the cron to edit its schedule in the Inspector, under Cron settings.

Cron Time has six fields:

Field	Meaning	Values
sec	second	0 - 59
min	minute	0 - 59
hour	hour	0 - 23
day	day of the month	1 - 31
mth	month	1 - 12
week	day of the week (0 = Sunday)	0 - 6

Each field accepts:

• *: any value;
• */n: every n values;
• n/m: every m values starting at n;
• n: a specific value;
• n-m: a range of values.

The Quick setup menu fills common schedules (every minute, every 5 minutes, every hour, day, week, month, year), and Description spells out the current schedule in plain English.

Expression	Runs
0 * * * * *	Every minute
0 */5 * * * *	Every 5 minutes
0 0 9 * * 1-5	At 9:00 on weekdays
0 0 0 1 * *	On the first day of each month, at midnight

Test in the editor

Under Cron trigger:

Option	Description
Active	Whether the cron is active.
Trigger	Whether the cron should also fire while the editor is open. Next trigger then shows when it will run.
Manual trigger	Runs the cron right now.

TIP

Keep Trigger off while you work, and use Manual trigger to test the cron when you need it.

In the exported app, crons start with the backend server.
