One of the many great benefits of having a Drupal website is developing custom Drupal modules. Today, we will discuss best practices when building custom Drupal modules, as well as some of the great modules already available to take advantage of.
What is Drupal?
Drupal is a content management system (CMS) that powers nearly 1.2 million websites worldwide. Drupal is used by a variety of different businesses, and powers websites for a variety of businesses ranging from personal blogs to large corporate companies. Drupal is known for its reliable security features, superior performance, and community support. It offers a number of great standard features that allow non-technical users to manage and update content, and many take advantage of its client side editing features. It is often used by developers for custom website design due to its ability to extend its functionality through modules and content presentation through themes. Drupal also offers the ability to integrate various software components, making it flexible for different business needs.

- Managing navigation
Beyond core modules, Drupal also offers the option for custom modules to be integrated into a website that are built by an outside web developer. When building custom modules, we have a few suggestions for best practices. If you are considering building a custom Drupal module or hiring a developer, these tips are great to refer back to.
1. Ensure Understanding of Requirements and Proper Setup
You want to be sure that your custom module will run smoothly, so we recommend looking into the proper environment before beginning the project to make coding smooth and simple. Make sure you have the proper software setup installed so you can effectively write, compile, and execute your module properly.
2. Create a Directory for Your Module
After setting up the environment, you will then need to create a custom folder within your Drupal directory (this can be found under modules/custom/mypage on Drupal 8).
3. Give Your Module a Good Name
After creating a directory for your module, you will want to give it a good name to locate it easily. We recommend naming it something that relates to its functionality (the name of your module should also end ininfo.yml).
4. Refer to Drupal 8 Solutions When Constructing Your Module
If you are building within Drupal 7, refer to Drupal 8 as a reference point when building your module. Drupal 8 may offer a solution that relates to the functionality you are looking to create, so this will make the building process much simpler.
5. Validate The Server Side Throughout the Project
Many Drupal developers will validate the client side when building a module to make sure its functionality is displaying correctly on a web page. It is also important to double check the server side, as this will prevent any long-term errors caused by incorrect coding.
6. Use Cache to Back Up Work
Cache is a high-speed memory storing mechanism. When building your module, be sure to use cache to back up any work you have done and prevent data loss.
7. Use the Most Up to Date Hooks
Hooks allow modules to interact with the core code of Drupal. Hooks allow modules to define new pages within a website, adding content to pages and setup customizable databases, tables, and more.
Hooks occur at various points through all enabled modules at various points throughout the execution of a custom project. Since all these components work in sync with each other, using the most up to date hooks when building your module will ensure everything works together and properly updates.
8. Properly Built Modules Ensure Long Term Success
Make sure to familiarize yourself with the best PHP options and the version of Drupal you are working within, since there are many differences between Drupal 7 and 8. Drupal 8 also offers the inclusion of the TWIG engine template, making the coding process less time-consuming.
9. What are some awesome existing modules on Drupal 8?
If you are thinking of upgrading to the latest version of Drupal, below are a few existing modules you may want to take advantage of:
