,handlerName
,data
,status
,isRecurrent
,recurrenceInterval
,maxRecurrences
, andretries
.JobHandler
: This is a function that a job runs when it's its turn to be executed by the queue.JobHandlerRegistry
: This class manages job handlers. It allows for registering and retrieving handlers by name.Queue
: This is the main class of this package. It's responsible for managing and executing jobs.JobStatus
: An enum representing the different states a job can be in.
Usage
import { Queue, JobConfig } from '@windingtree/sdk-queue';
// Create a new queue
const queue = new Queue({ concurrencyLimit: 5 });
// Register a job handler
queue.registerHandler('myHandler', async (data) => {
// Process data here
console.log(data);
return true;
});
// Create a job config
const jobConfig: JobConfig = {
handlerName: 'myHandler',
data: { key: 'value' },
maxRetries: 3,
};
// Add a job to the queue
const jobId = queue.add(jobConfig);
// You can also get a job
const job = queue.get(jobId);
// Or cancel a job
queue.cancel(jobId);
// Or delete a job
