Drupal 8 - Directory Structure
1. /core - Drupal core files like script, misc, themes etc.2. /libraries - 3rd party libraries, i.e. “wysiwyg editor”3. /modules – To place contributed and custom modules4. /profile - contributed and custom profiles5. /themes - contributed and custom (sub)themes6. sites/[domain OR default]/{modules, themes} - Site
specific modules and themes can be moved into these directories to avoid them showing up on every site
7. sites/[domain OR default]/files - Files directory

Basic Module Files
Only “.info.yml” file is required for Drupal 8.
× In Drupal 8, we don’t need “.module file”

Drupal 8 - .info.yml file
Drupal 8 introduced new info file for component i.e. “.info.yml”. So all .info files are moved to .info.yml files. The new file extension is .info.yml.
This applies to Modules Themes ProfilesAugust 19, 2015
www.ikonami.net
.info.yml syntax
In .info file we used equal(=) for assigning and square brackets([]) for array. In .info.yml we will use colon(:) for assigning and start space and dash for array.For the most part, change all = to :.
For arrays (e.g. dependencies[] = node), use the following format in Drupal 8:dependencies: - node
In Drupal 7 we use ; for Comments BUT in Drupal 8 we will use # for Comments.August 19, 2015
www.ikonami.net
Modified entries in .info.yml File • New Required Element type–A new type key is now required with values that indicate the type of extension. Use module, theme or profile. For example:–type: module
• Remove files[] entries–Remove any files[] entries. Classes are now autoloaded.
• Convert configure links to route names–In Drupal 8, specify the administrative configuration link using the route name instead of the system path.
• Drupal 7–configure = admin/config/system/actions
• Drupal 8–configure: action.admin

Create your “First module”
Create your info file in your module directory
/modules/hello_d8/hello_d8.yml.
name: Hello D8description: Demonstrate Drupal 8 module development.type: modulecore: 8.x
August 19, 2015

Create Menu• In drupal 8 “hook_menu” has been removed and introduced Routing-
Approach.
• Create routing file like [your_module].routing.yml
/modules/hello_d8/hello_d8.routing.yml
hello_d8.page:path: /hello-d8/pagedefaults: _controller: 'Drupal\hello_d8\Controller\HelloD8Controller::pageCallback’ _title: 'Hello Drupal 8’
Requirements: _permission: 'access content'
August 19, 2015
www.ikonami.net
Create your module controller
As Drupal 8 follows PSR-4 folder structure so you need to create your controller file under /modules/hello_d8/src/Controller/HelloD8Controller.php
<?php
namespace Drupal\hello_d8\Controller;
use Drupal\Core\Controller\ControllerBase;class HelloD8Controller extends ControllerBase { public function pageCallback () { return [ '#markup' => $this->t('Welcome Drupal 8 uesers') ]; }}

hello_d8.config: path: /admin/config/system/hello-d8-config defaults: _form: 'Drupal\hello_d8\Form\ConfigForm' _title: 'Drupal 8 Configuration' requirements: _permission: 'configure_hello_d8'
August 19, 2015

Create your form in Drupal 8Create your form class to build your form.<?phpnamespace Drupal\hello_d8\Form;use Drupal\Core\Form\ConfigFormBase;use Drupal\Core\Form\FormStateInterface;
class ConfigForm extends ConfigFormBase { protected function getEditableConfigNames() { return ['hello_d8.settings']; } public function getFormId() { return 'hello_d8_config'; } function buildForm(array $form, FormStateInterface $form_state) { $config = $this->config('hello_d8.settings'); $form['default_count'] = [ '#type' => 'number', '#title' => $this->t('Default count'), '#default_value' => $config->get('default_count'), ]; return parent::buildForm($form, $form_state); } public function submitForm(array &$form, FormStateInterface $form_state) { parent::submitForm($form, $form_state); $config = $this->config('hello_d8.settings'); $config->set('default_count', $form_state->getValue('default_count')); $config->save(); }}

Drupal 8 - Plugin API
Plugins are small pieces of functionality that are swappable. Plugins that perform similar functionality are of the same plugin type.

Drupal 8 - Block CodeCreate your plugin class /modules/hello_d8/src/Plugin/Block/HelloD8Block.php
<?phpnamespace Drupal\hello_d8\Plugin\Block;use Drupal\Core\Block\BlockBase;/** * Create hello_d8 block. * @Block( * id = "hello_d8_block", * admin_label = @Translation("Hello Drupal 8"), * category = @Translation("System") * ) * */class HelloD8Block extends BlockBase { public function build() { return [ '#markup' => $this->t('Hello Drupal 8 block.') ]; }}
