What are the best practices for creating modular codebases?

Creating modular codebases involves several best practices, such as keeping modules small and focused, ensuring high cohesion within modules, and low coupling between them. Additionally, using clear naming conventions and maintaining proper documentation can greatly enhance modularity.

Can you explain what high cohesion and low coupling mean?

High cohesion means that the elements within a module are closely related and work together to achieve a single purpose. Low coupling refers to minimizing dependencies between modules, allowing them to function independently. This makes the codebase easier to maintain and scale.

What tools can help in managing modular codebases?

There are several tools that can help manage modular codebases, such as package managers like npm or Yarn for JavaScript, and build tools like Webpack or Parcel. Additionally, using version control systems like Git can help track changes and manage different modules effectively.

How do I ensure my modules are reusable?

To ensure your modules are reusable, design them with clear interfaces, avoid hardcoding values, and make them configurable. Additionally, writing unit tests for your modules can help ensure they work correctly in different contexts.
