Joomla 4 – What and why you must know about it

Joomla 4 – What and why you must know about it

*Updated in Oct 2016

So, Joomla 3.5 is out of the oven and we are going to get Joomla 3.6 soon (haven’t heard of this? Read here). Is it too soon to talk about Joomla 4 (a.k.a Joomla X, with X = 4)?

No, I don’t think so. You probably already knew about Joomla 4 – what is called “the pipeline” of Joomla development this year although there is no official release time yet. In parallel with the development of Joomla 3.x, Joomla 4 is on its way to form itself by the hard work of Joomla 4 working group.

Now let’s take a look at what is supposed to be in this renovating Joomla version as well as why you should pay close attention to it.

*Please note that the features are not official yet and they might be changed later

Why the transformation in Joomla 4?

Though Joomla has been improving through the time, Joomla however is based on 10 years old technologies. So, it can’t respond to many modern technologies. It’s like an old-fashioned Joomla. You may defend that there are many people still using it, but please take note that there are not so many new users and new Joomla users from the market hasn’t been expanding.

Furthermore, the outdated technologies prevent developers from doing many things to build great projects with it. So, Joomla must transform to catch up with the modern technology and be more responsive to the need of its users.

Changes in Joomla 4 that affect developers

Here’s what Mike Veeckmans wrote about Joomla 4:


“This will be an evolution of the Joomla! series with the goal of improving both user experience and code quality. Joomla! 4 will not be a massive ground up refactor of the code base. The intention is to give Joomla! large functionality improvements with limited backward compatibility breaks.”


Basically, Joomla 4 is about new things that break what are existing in order to have a totally new version.

As stated in its development roadmap, Joomla 4 will continue the evolution of Joomla itself to become a more powerful yet easy to use CMS platform. Also its changes will enhance the unique characters that differentiate Joomla from other CMSs.

The priority in Joomla 4 development lies in having a one-click upgrade for core, minimal backwards compatibility breaks for the current extensions. However it’s also expected to create new ways to do other things for developers who wish to try them.

Great improvements in Joomla admin workflow

The development team has been working on a new and useful Joomla admin dashboard. It’s the very first thing users see after logging in the admin area so they are trying to make it better for users with useful, relevant information right in the dashboard.

Also there will be new onboarding process to help new Joomla users become familiar with Joomla much easier. Plus, Parameter Defaults Review is also going to be in the development team’s consideration.

An evolution in Joomla code

Coding improvements in Joomla 4 will make you dance on your feet, my fellow developers! Code in Joomla core will be more testable (so less bugs, of course) and easier to maintain.

I can list out some improvements in coding you can expect in this awesome version: a new rewritten plugin system, Dependency Injection Containers to replace JFactory, Joomla framework to be used in more components (so less code to maintain later), Code Namespacing and Depreciation.

Orthogonal Component Structure

Orth…orthogono..what? What a long name to remember! Let’s understand it this way instead:

Joomla 4 structure is the combination of vertical components like content or users and horizontal components like workflow, tagging, versioning. This means while we have the development in Joomla core, at the same time all the new features regarding functionality like publishing, tagging and versioning, etc. will be added automatically in Joomla and all are configurable.

You can learn more about this new structure here.

A modern CSS framework

Escaping from the cage of Bootstrap 2 with which Joomla has been stuck for a long time, Joomla 4 and its later versions will stay up-to-date with latest Bootstrap version. (Bootstrap 4). I’m sure that all designers will love this!

Along with this is something called JLayout to develop a common JavaScript library proxying to Bootstrap. This will help reduce the work a developer has to do to make Joomla extensions run properly on all Joomla templates. Designers will be benefited with JLayouts too since this helps make all HTML overridable - so designers now have more power in full customizability for their Joomla website.

MVC Implementation

“For Joomla 4, we restrict the duties of a component. So a component is asked to only implement its own core functionality. Everything else is pulled out into the system” – said Marco Dings at JWC 2015. So there will be much less codes extension developers have to write! Internally, they will use “command bus” to oversimplify extend the functionality where we have a single yet multitask controller.

The way Joomla 4 is applied the MVC will define the orthogonal component structure and how it works.

Why Joomla users, especially developers, should pay attention to Joomla 4?

Joomla 4 user experience

Joomla 4 is a giant step ahead of previous Joomla version.

You will need to update and change your codes in Joomla 3.x extensions to make them compatible with Joomla 4.

However on the bright side, with Joomla 4 makes it easier for developers to build extension with free tags, versioning, etc. Plus, the weight of tasks for a developer is lightened since there are many improvements to reduce unnecessary common tasks for them.

For end-users, Joomla 4 will surely be a new breeze for them – there will be simplified installation, easier and integrated admin configuration, easier module configuration, better version staging, better media manager and many more. Since it is heavily focused on user experience, Joomla 4 will be a true star CMS for end users.
