Advanced Queue Comprehensive Guide for Developers

Welcome to the comprehensive guide on advanced-queue, a powerful tool for managing queuing tasks in your applications.
This guide covers dozens of useful API explanations with code snippets to help you master the usage of advanced-queue.

Introduction

Advanced Queue is a robust library for managing task queues within your application. Whether you are building a complex
system requiring task scheduling or a simple job processor, Advanced Queue can simplify your workflow.

API Examples

Initialization

To get started with Advanced Queue, you need to initialize it with your configuration:

  const AdvancedQueue = require('advanced-queue');
  const queue = new AdvancedQueue({
    concurrency: 5,
    autoStart: true
  });

Adding Tasks to the Queue

You can easily add tasks to the queue using the add method:

  queue.add(() => {
    return new Promise((resolve) => {
      console.log('Task 1');
      resolve();
    });
  });

Handling Task Completion

Listen to task completion events using the on method:

  queue.on('complete', () => {
    console.log('All tasks completed');
  });

Pausing and Resuming the Queue

You can pause and resume the queue processing with ease:

  queue.pause();
  console.log('Queue paused');

  queue.resume();
  console.log('Queue resumed');

Removing Tasks from the Queue

If needed, you can remove tasks from the queue:

  const task = queue.add(() => doSomething());
  queue.remove(task);

Example Application

Below is a complete example application using Advanced Queue to process tasks:

  const AdvancedQueue = require('advanced-queue');

  const queue = new AdvancedQueue({
    concurrency: 3,
    autoStart: true
  });

  function simulateTask(id) {
    return () => {
      return new Promise((resolve) => {
        console.log(`Task ${id} started`);
        setTimeout(() => {
          console.log(`Task ${id} completed`);
          resolve();
        }, 1000);
      });
    };
  }

  for (let i = 1; i <= 10; i++) {
    queue.add(simulateTask(i));
  }

  queue.on('complete', () => {
    console.log('All tasks have been processed');
  });

This example sets up a queue with a concurrency of 3, simulates tasks, and processes them in the queue.

Conclusion

Advanced Queue is an essential library for task management and queuing in your applications.
With the examples provided, you should be well-equipped to integrate Advanced Queue into your projects
and streamline your task processing workflows.
