BackendService - schedule example

Run server-side code on a predefined time interval

The following example illustrates how to run server-side code on a predefined interval.

import { ApplicationBackendServiceBase, BackendServiceEventTypes } from '@dms';
import { MyEvent } from '@dms-bo';
export * from '@dms';
export * from '@dms-bo';

export default class BackendService extends ApplicationBackendServiceBase {

    public async processEvent(
         event: { eventName: string;
         eventArguments: {
                appArea: string;
                appCode: string;
                userName: string;
                request: {
                    httpMethod: string;
                    restCommand: string;
                    headers: any;
                    body: any;
                    queryStringParameters: any;
                };
          };
        }): Promise<any> {

        switch (event.eventName) {
            case "system:schedule:tick": {
                //create a new record in the database on every call
                const myEvent = new MyEvent();
                myEvent.onDateAndTime = moment(new Date()).toDate();
                await myEvent.add();
                break;     
            }
            default: return;
        }
    }
}

The given code will be only called on each system tick , which will make your code to run regularly.
