Cron

The Cron component can be used to schedule messages based on specific moments in time. It uses cron tabs to indicate when to send a message into the flow.

This component stays in a waiting state until a message is received. Once the component is running, jobs will start executing.

Configuration

Cron Jobs

The list of jobs with their respective cron tabs, and the message they output.

Syntax:cron tab | data (only string supported) | comment

Examples: */5 * * * * *| ping - Will send the message ping every 5 seconds.

As Object

Whether or not to send the output as an object, or as a raw string. If this is set to true a message in the format { message: "ping" } will be sent.

Cron tab:
