Dependency Injection is a design pattern that helps decouple the different components of a software application. It is a software design pattern that helps to manage the dependencies between different components in a software system. It involves passing the required dependencies into a class, rather than letting the class create or locate them itself.

Drupal is a content management system that allows you to create and manage website content in an organized way. One of the ways to create content in Drupal is by creating a node programmatically. A node is a fundamental building block of a Drupal website and represents a piece of content such as an article, a page, or a product.

To create a node programmatically in Drupal 8+, you will need to use the Drupal's Entity API, specifically the Node class. Here's an example of how you can create a basic node:

I know that I can programmatically create a user using the following code, in Drupal .

<?php

use Drupal\user\Entity\User;

// Create user object.
$user = User::create();

//Mandatory settings
$user->setPassword("password");
$user->enforceIsNew();
$user->setEmail("email");
$user->setUsername("username");
$user->addRole('role_name');
$user->set("field_machine_name", 'value');       
$user->save();

GitFlow is a branching model for Git, created by Vincent Driessen. It has attracted a lot of attention because it is very well suited to collaboration and scaling the development team.

But Sass wants to make your life easier. Rather than repeating the same selectors over and over again, you can write one style rules inside another. Sass will automatically combine the outer rule’s selector with the inner rule’s.

code sass

nav {
  ul {
    margin: 0;
    padding: 0;
    list-style: none;
  }

  li { display: inline-block; }

  a {
    display: block;
    padding: 6px 12px;
    text-decoration: none;
  }
}

code css

Nested rules are clever about handling selector lists (that is, comma-separated selectors). Each complex selector (the ones between the commas) is nested separately, and then they’re combined back into a selector list.

code sass

.alert, .warning {
  ul, p {
    margin-right: 0;
    margin-left: 0;
    padding-bottom: 0;
  }
}

code css

.alert ul, .alert p, .warning ul, .warning p {
  margin-right: 0;
  margin-left: 0;
  padding-bottom: 0;
}

We know Taxonomy is a powerful core module and helps us categorize the content. A vocabulary in Drupal is essentially a container for terms that are used by the system. These terms are what Drupal uses to connect certain areas together within the website.

How do I create a role programmatically in Drupal 8+

//your data array
$data = array('id' => 'client', 'label' => 'Client');
//creating your role
$role = \Drupal\user\Entity\Role::create($data);
//saving your role
$role->save();

In my case, I wanted to be able to auto-create multiple roles ("clients","managers","salesrep") to work with my custom module.

This is how I auto-create roles programmatically in Drupal.
