cron(): Promise<void>
Create a cron job that will periodically execute the provided handler callback based on the specified schedule.
Deno.cron("sample cron", "20 * * * *", () => {
console.log("cron job executed");
});
Deno.cron("sample cron", { hour: { every: 6 } }, () => {
console.log("cron job executed");
});
schedule
can be a string in the Unix cron format or in JSON format
as specified by interface CronSchedule
, where time is specified
using UTC time zone.
Promise<void>
cron(name: string,schedule: string | CronSchedule,options: { backoffSchedule?: number[]; signal?: AbortSignal; },handler: () => Promise<void> | void,): Promise<void>
Create a cron job that will periodically execute the provided handler callback based on the specified schedule.
Deno.cron("sample cron", "20 * * * *", {
backoffSchedule: [10, 20]
}, () => {
console.log("cron job executed");
});
schedule
can be a string in the Unix cron format or in JSON format
as specified by interface CronSchedule
, where time is specified
using UTC time zone.
backoffSchedule
option can be used to specify the retry policy for failed
executions. Each element in the array represents the number of milliseconds
to wait before retrying the execution. For example, [1000, 5000, 10000]
means that a failed execution will be retried at most 3 times, with 1
second, 5 seconds, and 10 seconds delay between each retry.
