Managing Dependencies in Custom Drupal Modules: Best Practices for Seamless Integration

Managing dependencies in a custom Drupal module is essential for ensuring seamless functionality and integration within the ecosystem, as Mohammad Anwar Siddiqui highlighted in his blog post on Medium. This involves declaring module dependencies in the .info.yml file, using Composer to manage external libraries, and utilizing dependency injection for better code organization. 

Mohammad provides a detailed example of handling complex dependencies, such as integrating with external APIs, processing data through custom services, and storing it in custom entities. By adhering to these best practices, developers can maintain efficient, testable, and scalable modules that work cohesively with other Drupal components. By using tools like Guzzle for API requests and proper service definitions, complex dependency management becomes more structured, leading to reliable module performance.
