Create a Module has some changes in  Magento 2. Create a Magento 2 Module now have a bit different from Magento 1. And of course, you must learn about it.

Step 1: Create a module folder for Magento 2 Modules

We use module vendor Magezend  and module name is HelloWorld. So we need to create a new folder:         app/code/Magezend/HelloWorld

Step 2: Declare the module by module.xml

• We need create a configuration in module etc directory. Magento 2 will use it to recognize the module’s name and module’s version
  • app/code/Magezend/HelloWorld/etc/module.xml
• Add this content to declare module name is HelloMangento and version 1.0.0

Step 3: Register the module by registration.php

• This file will be created in magento root folder:
  • app/code/Magezend/HelloWorld/registration.php
• Add this content to registered the module:

Step 4: Install Setup, Enable the module

After create all files of above steps. We can install the module through command line. Please open your terminal and use these commands:

Additionally, we can use some commands to view disabled module list, enable or disable a module:

• View disabled modules:
  • php bin/magento module:status
• Enable module:
  • PHP bin/magento module:enable Magezend_HelloWorld
• Disable module:
  • PHP bin/magento module:disable Magezend_HelloWorld
• 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 Magezend_HelloWorld

Step 5: Create a route for the module

• Both of Magento 1 and Mmagento 2 use this format url:
  • http://<magento_url>.com/<router_name>/<controller_name>/<action_name>
    Example: http://<magento_url>.com/customer/account/create
• So we need init router name for the module before creating any controllers and actions in the future.
• Create a routers.xml file:
  • app/code/Magezend/HelloWorld/etc/frontend/routes.xml
• Add this content:

Step 6: Create controller and action

• In the last step, we will create url for displaying in your browser: “Hello Magento 2. We will change the world”.
• Create an action file:
  • app/code/Magezend/HelloWorld/Controller/Index/Index.php
• Add the content:

Result: 

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