Scheduler

Overview

The Scheduler Component triggers jobs periodically at fixed times, dates, or intervals using cron syntax. It is useful for automating recurring tasks within a workflow.

Usage

This component enables users to schedule execution times based on minutes, hours, days, and specific time zones. It supports immediate triggering when a flow starts.

Output Ports

Port	Description
out	Emits scheduled timestamps based on the defined cron schedule.

Output Properties

Property	Type	Description
previousDate	string	The last scheduled execution time (ISO 8601 format).
now	string	The current execution time (ISO 8601 format).
nextDate	string	The next scheduled execution time (ISO 8601 format).

Properties

Property	Type	Description
minute	string	Cron expression for minutes (*, -, /, 0-59, etc.).
hour	string	Cron expression for hours (*, -, /, 0-23, etc.).
dayMonth	string	Cron expression for days of the month (*, -, /, 1-31, etc.).
dayWeek	string	Cron expression for days of the week (*, -, /, 0-6, SUN-SAT, etc.).
immediate	boolean	If true, triggers execution immediately upon starting the flow.
timezone	string	Timezone for scheduling (e.g., 'Europe/Prague', defaults to GMT).

Processing Logic

1. Define Scheduling Rules: The user sets up cron-like expressions to determine execution times.

2. Trigger Execution: The component schedules the task based on the defined rules.

3. Generate Timestamps: Outputs previousDate, now, and nextDate at execution time.

Notes

• Flexible Scheduling: Supports standard cron expressions for precise scheduling.

• Immediate Execution: Can trigger immediately when a flow starts if immediate is set to true.

• Timezone Support: Users can specify a timezone for accurate scheduling across different regions.

This component is ideal for time-based automation, recurring task execution, and scheduling workflows efficiently.
