Here the following steps explain you how to Form a Module in Magento 2:

Step 1: Form a module folder:

Step 2: State the module by module.xml

Step 3: Register the module by registration.php

Step 4: Install Setup, allow the module

Step 5: Form a route for the module.

Step 6: Form controller and action.

There are some changes in Magento 2 to form a block. Form a block in Magento 2 is now a bit different from Magento 1. Of course, you need to know about it.

Step 1: Form a module folder:

We utilize module vendor Webnexs and module name is Hello Magento. So we require form a new folder: app/code/Webnexs/HelloMagento

Step 2: State the module by module.xml

• We need form a configuration in module etc directory. Magento 2 will use it to know the module’s name and module’s version
• app/code/Webnexs/HelloMagento/etc/module.xml
• include this content to state module name is HelloMangento and version 1.0.0

<?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="Webnexs_HelloMagento" setup_version="1.0.0" />

</config>

Step 3: Register the module by registration.php

This file will be formed in magento root folder:

app/code/Webnexs/HelloMagento/registration.php

Include this content to register the module:

<?php

\Magento\Framework\Component\ComponentRegistrar::register(

    \Magento\Framework\Component\ComponentRegistrar::MODULE,

    'Webnexs_HelloMagento',

    __DIR__

);

Step 4: Install Setup, allow the module

After form all the above formats. You can install volumes by command line. Please open your terminal and use these commands:

cd [magento_directory]

php bin/magento setup:upgrade

Moreover, we can use some commands to sight disabled module list, permit or disable a module:

• Analysis disabled modules:

php bin/magento module:status

• Permit module:

PHP bin/magento module:enable Webnexs_HelloMagento

• Disable module:

PHP bin/magento module:disable Webnexs_HelloMagento

Note:  If you use xampp in ubuntu, please type the correct directory for using php command.

Example:/opt/lampp/bin/php  bin/magento  module:disable Webnexs_HelloMagento

Step 5: Form a route for the module.

• The magento 1 and magento 2 use this design: URL:http://<magento_url>.com/<router_name>/<controller_name>/<action_name>

Example: http://<magento_url>.com/customer/account/create

• So we require init router name for the module before forming any controllers and actions in the future.
• Form a routers.xml file:

app/code/Webnexs/HelloMagento/etc/frontend/routes.xml

• Include this content:

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">

    <router id="standard">

        <route id="Webnexs" frontName="hellomagento">

            <module name="Webnexs_HelloMagento" />

        </route>

    </router>

</config>

Step 6: Form controller and action.

• In the final step, we will form url for showing in browser: “Hello Magento 2. We will modify the world”.
• Form an action file:

app/code/Webnexs/HelloMagento/Controller/Index/Index.php

• Include the content:

<?php

namespace Webnexs\HelloMagento\Controller\Index;


class Index extends \Magento\Framework\App\Action\Action

{

  public function __construct(

\Magento\Framework\App\Action\Context $context)

  {

    return parent::__construct($context);

  }


 public function execute()

  {

    echo 'Hello Magento 2! We will change the world!';

    exit;

  }

}

Result:

Open your browser, type this link: http://<magento_url>/hellomagento/index/index and look at the result:
