Drupal is a great content management system, that everyone should use to build their systems. In today’s article we are going to talk about another Drupal concept which we need to delve a bit deeper, this concept is known as modules. If you would like your site to be more dynamic, by adding new features and extending Drupal core, then you’d need to know what a module is and know how to use and develop them.
Developers can also alter existing functionality developed a website, which meet the requirements of stakeholders, by only using the features of Drupal that they need. Community-contributed modules are available to any developer, who wish to fulfil a certain specific purpose.
Custom modules are types of modules, that usually reside in the /modules/custom directory, they are project-specific, and written for a specific application. Contributed modules are another type of modules, found and downloaded from Drupal.org, these modules are placed in the /modules/contrib directory and are not part of Drupal core.
Another type of modules are core modules, these modules are found in the /core/modules/ directory and are part of Drupal core. During the development of a module, it is a very good idea to understand how to secure, and keep the code updated, so that the website does not suffer, from security vulneraries and is always up to date.
Another thing to remember when writing code to develop a custom module, is to adhere to Drupal’s coding standards.
It is important to understand what coding standards are and why they are important to follow, to write code. The set of rules designed for programmers, which define best practices, code formatting and various other rules, is known as coding standards. Following coding standards, can help programmers on a team, to be able to follow and understand each other’s code, because everyone would have to follow the same conventions.
Developers learn how to style and format their code, by following code standards, which define how the code will be read and how it will look. Indentation, whitespace and line length are all part of the style coding standards of Drupal. The whole Drupal project has a sense of coherence, when developers across the globe, using Drupal adhere to the same coding standards.
Setting up expectations on how code should look, is a good thing, and makes coding standards very important. It is essential in a community like Drupal, for developers to follow coding standards, because developers around the world, can read, maintain and modify each other’s code. Drupal’s codebase can also stay consistent, when there are concrete coding standards, to follow.
Another important part of code standards is substance, which has information about the content and standard of your code. The use of various functions and components in your code, is very important according to substance coding standards.
