How to Add a Progress Bar using Custom CLI Command in Magento 2

Hello Magento Friends,

In today’s article, we will learn about How to Add a Progress Bar using Custom CLI Command in Magento 2.

Sometimes a customer needs to wait for the process to be completed while working with Magento. A progress bar is used when you want to indicate to the customer about the process and its status.

You can create a progress bar using custom CLI commands in Magento 2. Let’s learn how

Steps to Add a Progress Bar using Custom CLI Command in Magento 2:

Step 1: Navigate to the below path

app\code\Vendor\Extension\etc\di.xml

Now, add the below code

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Framework\Console\CommandListInterface">
        <arguments>
            <argument name="commands" xsi:type="array">
                <item name="vendor_progress_bar" xsi:type="object">Vendor\Extension\Console\Command\ProgressBarCommand</item>
            </argument>
        </arguments>
    </type>
    <type name="Vendor\Extension\Console\Command\ProgressBarCommand">
        <arguments>
            <argument name="name" xsi:type="string">magecomp:custom:progress-bar</argument>
        </arguments>
    </type>
</config>

Step 2: Then go to the following path

app\code\Vendor\Extension\Console\Command\ProgressBar.php

Then move to the below path

<?php

namespace Vendor\Extension\Console\Command;

use Magento\Directory\Model\ResourceModel\Country\CollectionFactory;
use Magento\Framework\Console\Cli;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Helper\ProgressBar;
use Symfony\Component\Console\Helper\ProgressBarFactory;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

class ProgressBar extends Command
{
    /**
     * @var ProgressBarFactory
     */
    private $progressBarFactory;

    /**
     * @var CollectionFactory
     */
    protected $_customer;
    
    protected $_customerFactory;

    /**
     * @inheritDoc
     */
    public function __construct(
        ProgressBarFactory $progressBarFactory,
        \Magento\Customer\Model\CustomerFactory $customerFactory,
        \Magento\Customer\Model\Customer $customers,
        string $name
    ) {
        $this->progressBarFactory = $progressBarFactory;
        $this->_customerFactory = $customerFactory;
        $this->_customer = $customers;

        parent::__construct($name);
    }

    /**
     * @inheritDoc
     */
    protected function configure()
    {
        parent::configure();
    }

    /**
     * Execute the command
     *
     * @param InputInterface $input
     * @param OutputInterface $output
     *
     * @return int
     */
    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $output->writeln('<info>Execution starts.</info>');

        $customercollection = $this->_customer->getCollection()->addAttributeToSelect("*")->load();
        
        /** @var ProgressBar $progress */
        $progressBar = $this->progressBarFactory->create(
            [
                'output' => $output,
                'max' => count($customercollection),
            ]
        );

        $progressBar->setFormat(
            'Customer/Collection    %current%/%max% %bar% %percent:3s%% %elapsed% %memory:6s%'
        );

        $progressBar->start();

        foreach ($customercollection as $customer) {
        
           /* Add your custom functionality here */
           
            $progressBar->advance();
        }

        $progressBar->finish();
        $output->write(PHP_EOL);
        $output->writeln('<info>Execution ends.</info>');

        return Cli::RETURN_SUCCESS;
    }
}

Step 3: After that run the below commands

php bin/magento c:c
php bin/magento c:f

Now, you need to run the below command in Magento root:

sudo php bin/magento  magecomp:custom:progress-bar

The output will be as follows in the terminal after executing the above command.
