Cron Event​

( src/events/every_minute_task.yaml )

# event for Scheduling a task for every minute.
cron.* * * * *.Asia/Kolkata:   # event key
  fn: every_minute

Explanation of Cron Event Configuration:​

  • cron.*: This is the cron syntax for the field representing minutes. The asterisk (*) in this position means "every minute," so the event is scheduled to run every minute.

  • * * * * *: These asterisks represent the other cron fields, which specify the schedule for hours, days of the month, months, and days of the week, respectively.

  • Asia/Kolkata: This is a timezone specification. It indicates that the event is scheduled to run in the Asia/Kolkata timezone. Kolkata is a city in India, and this timezone corresponds to the Indian Standard Time (IST).

Cron workflow to schedule ( src/functions/every_minute.ts )​

import { GSCloudEvent, GSContext, PlainObject } from "@godspeedsystems/core";
/**
 * Prints a message every minute via cron
 */
export default function (ctx: GSContext) {
  const { logger, childLogger } = ctx;

  // Log using both loggers
  logger.info("HELLO from CRON");
  childLogger.info("HELLO from CRON");

  // Return the data
  return new GSStatus(true, 200, "message", "HELLO from CRON", undefined);
}
