In this post, you will find a collection of online guides on Drupal 8/9 module development. Pick one that suits you and follow the instructions. It’s true that becoming a competent Drupal 8/9 module developer takes more than reading one tutorial. Still, it’s a chance to look under the hood and see what Drupal module development is like.
Drupal is one of the comparatively few software products that has successfully stood the test of time. Released almost two decades ago, this Content Management Framework (CMF) is still the number one choice among companies of all sizes.
A CMF is more powerful than an ordinary content management system such as WordPress. It is, in fact, so powerful that it can serve as a basis for creating other content management systems by reusing software components. In the Drupal terminology, these recycled components are known as modules.
Modules bring flexibility to Drupal, making it suitable both for small business sites and enterprise applications. They are, in essence, folders that contain PHP, CSS, and JS files. Modules come in three flavors:
Let’s briefly talk about their main features, benefits, and drawbacks before we proceed to the discussion of Drupal module development tutorials.
These are shipped with every Drupal distribution package. There is no need to install them specifically. Just enable and use them. Examples include accessibility modules, such as the Inline Form Errors module, or modules for building multilingual sites like the Content Translation module. One of the key differences between Drupal 7 and Drupal 8/9 is the number and variety of core modules, with the latter having more of these than the former.
Core modules are “untouchable,” as one of the most important principles of Drupal development says that you should never change the core functionality. If you do, you may have to face a number of serious issues, such as:
What if you need a feature that the basic package doesn’t have, though? This is when you should either find a corresponding contributed module or hire a professional Drupal 8/9 module developer.
Drupal is famously known for its large and active developer community. There are lots of enthusiasts across the globe who want to improve the platform by creating new external modules for it. You can find thousands of free contributed modules on Drupal.org for all purposes imaginable, from search engine optimization to advertising.
This variety is actually a double-edged sword. A rank-and-file Drupal site owner will be hard-pressed to find a good contributed module that meets their granular requirements. There is a host of criteria to take into account:
Another important consideration is the version of Drupal that the module is compatible with. Drupal 8/9 uses a newer version of PHP. Therefore, if a module is intended for Drupal 7, it will be completely useless in Drupal 8/9. Read one of our previous posts on Drupal 7 to Drupal 8/9 migration for more insights on this.
In addition, contributed modules can include many redundant features you don’t really need. This may cause the website to run slower. Finally, the code of a contributed module may have conflicts with the core or other contributed modules you’ve installed before.
The best way to avoid all this trouble is Drupal 8/9 custom module development.
This is by far the best way to add unique features to a Drupal-based website. A Drupal 8/9 module developer creates a plugin that’s tailored to your specific project. For example, if you need to accept money from visitors, you can have your own checkout functionality.
Drupal custom module development can be more or less expensive. A developer can simply download an existing contributed module and modify it in any way they want (add your code, remove or change the existing code). This will normally take less time and require a smaller investment.
On the other hand, Drupal 8/9 plugin development from the ground up is quite common too. Whichever method you ultimately choose, the result should be a well-tested, lightweight module that satisfies all your business requirements. If you want to know how to develop a Drupal 8/9 module, we’ve outlined 3 online guides on Drupal 8/9 custom module development.

You’re invited to walk the entire way from getting started and creating a module skeleton to publishing a finished product on drupal.org, plus everything in between. You can also see great examples of Drupal modules on the Examples for Developers project page.
