@kijuub/timed-retry-dependency-queue v1.1.0

Timed Retry Dependency Queue

This is a queue implementation for the Timed Retry Queue package. It allows you to process a queue with dependencies on task execution.

Getting started

First install the base package.

yarn add @kijuub/timed-retry-queue
npm install @kijuub/timed-retry-queue

Now install the queue implementation.

yarn add @kijuub/timed-retry-dependency-queue
npm install @kijuub/timed-retry-dependency-queue

Usage

Check the default readme on how to create a task executor. Afterwards you just need to create the queue.

Adding tasks

To add tasks to the process method, you need to create the TimedRetryQueueTasks object. You can add both retry tasks or tasks that do not need to be retried.

import { TimedRetryQueue } from '@kijuub/timed-retry-queue'
import { TimedRetryDependencyTaskQueue } from '@kijuub/timed-retry-dependency-queue'

const executer = new TimedRetryQueue()

const queue = new TimedRetryDependencyTaskQueue()

const dummyFunction = () => {
    console.log( `Dummy function triggered ...` )
}

queue.addMany( [
    {
        task: dummyFunction,
        parameters: {
            extra: {
                dependencies: [ 'tasktwo' ],
                id: 'taskone'
            }
        }
    },
    {
        task: dummyFunction,
        parameters: {
            extra: {
                dependencies: [],
                id: 'tasktwo'
            }
        }
    },
    {
        task: dummyFunction,
        parameters: {
            extra: {
                dependencies: [ 'taskone', 'tasktwo' ],
                id: 'taskthree'
            }
        }
    },
] )

const process = await executer.process( queue )

The extra parameters contain the id of the task which must be unique, the dependencies array contains the list of IDs that are dependant upon the completion of this task. Note that the add method is not supported, only addMany.

All of the default options of the Timed Retry Queue are also available.

NOTE: The task is deemed failed if an error is thrown.
