Cron Processor

[jphgardner02]

Hi,

I am looking at using this library to allow my application to support background jobs.

Some jobs will be added to the Queue and others will need to be ran on a Cron Specification.

At the moment i am struggling to correctly configure a Cron Process.

`@Processor({ name: 'store' })
export class ScheduleService {

constructor(private readonly _http: HttpService,
			private readonly _connectionManager: ConnectionManagerService,
			private readonly _sanctionService: SanctionsService) {
}

@Process({ name: 'importSanctionList' })
/*@Cron('59 23 * * *', {
	enable: true,
	key: 'importSanctionList',
	startTime: new Date(),
	// immediate: true
	// endTime: new Date(new Date().getTime() + 24 * 60 * 60 * 1000),
})*/
async importSanctionList() {
	console.log("Run importSanctionList");
}

private _parseXML(xml) : Promise<any> {
	return xml2js.parseStringPromise(xml, {
		ignoreAttrs: true,
		trim: true,
		explicitArray: false,
		normalizeTags: true
	});
}

@OnQueueActive()
onActive(job: Job) {
	console.log(
		`Processing job ${job.id} of type ${job.name} with data ${job.data}...`,
	);
}

@OnQueueEvent(BullQueueEvents.COMPLETED)
onCompleted(job: Job) {
	console.log(
		`Completed job ${job.id} of type ${job.name} with result ${job.returnvalue}`,
	);
}

}`

I need the importSanctionList function to run at midnight every day.

Hi @jphgardner02
You could try to add a repeatable job in your queue. See https://optimalbits.github.io/bull#repeatable

@fwoelffel Is there a way to add this to the @ Process Decorator, or would i have to add a repeatable job everytime nestjs starts?

I haven't tried this myself, but I guess you would have to add the repeatable job everytime NestJS starts. According to Bull's documentation, the library is smart enough not to add/process the same repeatable job multiple times.
