PHP is the programming language in which Drupal software is written, so you should be comfortable with it before diving in. When creating solutions to meet their specific use case, developers do so with an eye towards creating reusable tools when possible, and/or collaborating with other developers to enhance existing tools that are close to, but not quite, the solution needed.ĭevelopers are generally expected to be proficient with Drupal site building, and to know how to leverage the ecosystem of existing contributed modules and Drupal core APIs in order to prevent duplication. One of the more common tasks that developers do is to create “glue-code”: modules that make minor alterations to the way an existing module works that are application-specific, or modules that tie existing modules together in a unique way, without modifying the original code. And those who care for them need to be able to focus entirely on providing the best treatment possible - not on dealing with a hopelessly broken drug supply system.ĭr.Developers, also known as engineers or programmers, use their knowledge of PHP, MySQL, HTML, JavaScript, and CSS to extend, alter, and enhance Drupal by creating modules.
