Creating a Job Queue

  
  const QJobs = require('qjobs');
  const jobQueue = new QJobs();
  

Adding Jobs to the Queue

  
  jobQueue.add(function (args, next) {
      console.log('Job 1 executed');
      next();
  });

  jobQueue.add(function (args, next) {
      console.log('Job 2 executed');
      next();
  });
  

Starting the Queue

  
  jobQueue.start();
  

Setting Concurrent Jobs

  
  jobQueue.setConcurrency(2);
  

Handling Job Completion

  
  jobQueue.on('end', function () {
      console.log('All jobs have been processed');
  });

  jobQueue.start();
  

Application Example

  
  const QJobs = require('qjobs');

  const jobQueue = new QJobs();
  jobQueue.setConcurrency(2);

  jobQueue.add(function (args, next) {
      console.log('Fetching data from API...');
      setTimeout(() => {
          console.log('Data fetched from API');
          next();
      }, 1000);
  });

  jobQueue.add(function (args, next) {
      console.log('Processing data...');
      setTimeout(() => {
          console.log('Data processed');
          next();
      }, 2000);
  });

  jobQueue.add(function (args, next) {
      console.log('Saving data into database...');
      setTimeout(() => {
          console.log('Data saved into database');
          next();
      }, 1500);
  });

  jobQueue.on('end', function () {
      console.log('All jobs completed successfully');
  });

  jobQueue.start();
