Material Cron Editor

This package is intended to facilitate the formatting of cron formatted strings, using Angular and Angular Material.
This is implemented using Angular's ReactiveFormsModule.

A working demo of this component can be seen here

Standard cron formats are supported as exemplified here

Dependencies

• Angular 10.1.4
• Angular Material 10.2.3

Installation

npm install mat-cron-editor

Usage

To configure the MatCronEditor component, one must declare a variable of type CronOptionsInterface.

For example:

cronOptions: CronOptionsInterface = {
    includeMinutes: true,
    includeHours: true,
    includeDates: true,
    includeMonths: true,
    includeDays: true,
    includeMinutesBetween: true,
    includeHoursBetween: true,
    includeDaysBetween: true,
    includeMonthsBetween: true,
    includeDatesBetween: true,
    showHints: true,
    defaultCron: '0 0 1 1 *',
    flexDirection: 'row'
  };

In your .html file you may now use the component as follows:

<mat-cron-editor
  [cronOptions]="cronOptions"
  (cronEvent)="showCron($event)">
</mat-cron-editor>

The defaultCron property will automatically set the values of the 'included' fields, if valid. The cronEvent emits an object with cronForm(the entire FormGroup so that user can make any additional manipulations as desired) and cronValue(the formatted cron value resulting from the form control values).

For example, accessing this emitted value we can set an instance variable each time the form values are changed, like so:

showCron(event): void {
  this.resultingCron = event.cronValue;
}
