How to apply patch in Drupal?

To create a module in Drupal, follow the steps given below: Navigate to

modules/custom/

in your Drupal installation and create a new folder for your module. Example:

 my_module 

. Inside your module folder, create an info file,

my_module.info.yml

, which tells Drupal about your module:

Create a

my_module.module

file for your module's custom logic (if needed). This file can contain hook implementations. If your module needs custom routes (like for a page), create a

my_module.routing.yml

file:

If you added a route, create a controller in

src/Controller/MyModuleController.php

Go to the Extend menu in Drupal's admin dashboard, find your module, and enable it.

To create a custom module in Drupal, follow the steps given below: Inside the
