How to create a custom extension in Magento 2?

In these steps, you will learn how to create a custom extension using a hello world module. Before we start, there are some requirements that we need to look upon.

2. You need to disable the Magneto Cache: It needs to be done so that you can save some time on the manual flush system when you make changes in the codes.
3. Select developer mode: It lets you see all the errors from Magento’s end.

STEPS DEMONSTRATING MAGENTO 2 EXTENSION DEVELOPMENT

Step 1- Create Extension files and folders for setup and registration

• Create 2 folders: app/code/Ksolves and app/code/Ksolves/Helloworld

In case you don’t have the code folder, then you can create it manually. Here, the extension name is Helloworld and the extension namespace is the Ksolves folder.

• Now with another code, you need to create a module.XML file in the “Helloworld” folder.
• To get this module registered, you need to create a registration.php file in the same helloworld folder.
• Go to Magento 2 root and then run the upgrade command.

Step 2- Create a Controller

• Create a routes.XML file in the “Helloworld” frontend folder by the required coding. With this, we are defining the frontend router. Next, you have to route with the id ‘helloworld’.
• Now you have to create the Index.php controller file in the Helloworld Controller/Index folder.

Step 3- Create a Block

You have to create a simple block class. It has to be created with getHelloworldTxt() method so that you can return the Helloworld string.

• The step to do so is: Create a Helloworld.php file in the Helloworld/Block folder.

Step 4- Create Template and Layout Files

Both template and layout files are placed inside the “View Folder” of your extension. Inside this “View Folder”, you will see three subfolders: Base, Adminhtml, and Frontend.

• The first step is creating a helloworld_index_index.XML file inside the frontend/layout folder of the view folder.

Now you have to create a helloworld.phtml file within the frontend/templates folder.

So, this is it. Just open this URL in your browser: /helloworld/index/index

You will see a page open saying “Hello Ksolves this is your first Hello world Magento extension!” Make sure to use the codes correctly.
