A Step-by-Step Guide to Creating Custom Modules in Magento 2


Magento 2 is a powerful e-commerce platform that allows you to extend its functionality by creating Magento 2 custom module. In this step-by-step guide, we’ll walk you through the process of creating a module in Magento 2, enabling you to add new features or modify existing ones to suit your business needs.

  1. Create module.xml

The first step is to create the module.xml file in the appropriate directory. Navigate to app/code/VenderName/ExtensionName/etc and create a new file named module.xml. Use the following XML code as the content of the module.xml file:

<?xml version=”1.0″?>
<config xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xsi:noNamespaceSchemaLocation=”urn:magento:framework:Module/etc/module.xsd”>
<module name=”VenderName_ExtensionName” setup_version=”1.0.0″>
</module>
</config>

  1. Create registration.php

Next, create the registration.php file in the module’s root directory (app/code/VenderName/ExtensionName). The registration.php file is responsible for registering the module with Magento 2. Add the following PHP code to the registration.php file:

<?php
use Magento\Framework\Component\ComponentRegistrar;
ComponentRegistrar::register(
ComponentRegistrar::MODULE,
‘VenderName_ExtensionName’,
__DIR__
);

  1. Execute Commands

After creating the necessary files, you need to execute some commands in the command line to enable the module and apply the changes. Open your terminal and navigate to the Magento 2 root directory. Run the following commands one by one:

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

The first command setup:upgrade will update the database schema with your new module. The second command setup:static-content:deploy -f will deploy static content to the appropriate directories. The last command cache:flush will clear the cache so that Magento recognizes the changes.

  1. Verify the Module

Once you’ve executed the commands successfully, the module will appear in the app/etc/config.php file. If the output of the command is ‘1’, it indicates that the module is enabled, and its functionalities are working as expected. If the output is ‘0’, the module is disabled.

Congratulations! You have successfully created and enabled a custom module in Magento 2. Now, you can start implementing the specific functionalities you want to add to your online store.

Remember, creating custom modules allows you to tailor your Magento 2 store according to your unique business requirements and offer a personalized shopping experience to your customers. Happy coding!
