Cron.json

The cron.json file, is one of the special-purpose files in the event-catalogue. This file is used to specify recurring events to post and their schedules.

File Format

The format for the file is

interface CronConfig {
  [event: string]: {
    expression: string,
    timezone?: string,
  }
}

Where expression uses the Cron format and timezone is a TZ Identifier. In this example we have two recurring events, one posts a minute event every minute, another posts a daily event every day at 2 pm CET:

{
  "minute": { "expression": "0 * * ? * * *" },
  "daily": { "expression": "0 0 14 ? * * *", "timezone": "CET" }
}

Deploying Recurring Events

When the event-catalogue is deployed, new events are automatically scheduled and removed events are cancelled. You can deploy the event-catalogue with the CLI:

mm deploy
