[b]Description[/b]
It has never been better time to learn Drupal 8 module development.

Thats because Drupal 8 is already the better technologically and the faster way to build Drupal applications (compared to Drupal 7).

Drupal 8 is built on top of Symfony so the good news are that as you learn how to create controller for example in Drupal 8 - the way you would do it in Symfony is quite the same and vice versa. Thats great because that actually means that the skills are transferable and that we are not going to be bogged down into endless drupalisms (Drupal-specific terms).

In this course we are going to learn the most popular sections of the Drupal 8 module development:

we are going to declare our own custom module
we are going to learn what is a controller and we are going to build our own controller class
we are going to learn how to implement new routes in the .routing.yml file
we are going to learn how to render controller content in twig template
how to include libraries (assets) when certain templates are being rendered
how to create custom blocks
have a good understanding of what Renderable arrays are
what in general are Services
how to declare a service
how to inject a service into our own service
how to inject a service to a container
how to create custom forms and act on submission
how to validate forms
how to alter any form
how to create an AJAX form
how to save our custom configuration to our won custom form admin page
how to render our custom configuration
how to declare permissions and how to make them work to restrict stuff .
We are going to implement as much examples as possible and always I attached for you the final files so that you could easily compare with the final result and not waste time on tracing a tiny-tiny bug.

I tried to make it as clear as possible and to share as much as possible examples that I face in my everyday work process as PHP Drupal developer. The skills that are covered in this course are surely stuff that you would need if your are building complex Drupal 8 applications and are "Must have" as a knowledge for every Drupal developer.

Who this course is for:
Drupal developers that want to learn coding
PHP developers that want to learn Drupal 8 coding
Symfony developers that want to learn how the code could be implemented in Drupal
people that like Drupal and programming
Drupal themers and site builders who want to learn programming
just about anyone who is willing to learn Drupal module development
