Package Exports

hapi-cron

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hapi-cron) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

    options: {
        jobs: [{

            request: {
                method: 'GET',
                url: '/test-url'
            },
            callback
        }]
    },
}, (err) => {

    if (err) {
        return console.error(err);
    }
    
    Server.start(() => {
    
        console.info(`Server started at ${ Server.info.uri }`);
    });
});

Plugin Options

name - [REQUIRED] - The name of the cron job. This can be anything but it must be unique.
time - [REQUIRED] - A valid cron value. See cron configuration
timezone - [REQUIRED] - A valid timezone.
request - [REQUIRED] - The request object containing the route url path. Other options can also be passed into the request object.
- url - [REQUIRED] - Route path to request
callback - [OPTIONAL] - Callback function to run after the route has been requested. The function will contain the response from the request.

Please note that the plugin only works when the server contains exactly one connection.

Cron configuration

This plugin uses the node-cron module to setup the cron job.

Available Cron patterns:

Asterisk. E.g. *
Ranges. E.g. 1-3,5
Steps. E.g. */2

Read up on cron patterns here. Note the examples in the link have five fields, and 1 minute as the finest granularity, but the node cron module allows six fields, with 1 second as the finest granularity.

Cron Ranges

When specifying your cron values you'll need to make sure that your values fall within the ranges. For instance, some cron's use a 0-7 range for the day of week where both 0 and 7 represent Sunday. We do not.

Seconds: 0-59
Minutes: 0-59
Hours: 0-23
Day of Month: 1-31
Months: 0-11
Day of Week: 0-6
