Reuse and Refactor

As your apps grow, keep them maintainable and scalable by centralizing the logic in a reusable, modular way. In OutSystems you can use different types of modules and reference them as producer modules. Similarly, the consumer modules use the elements of logic that the producers expose.

Here is an overview of module types.

You can also create blank modules, which are modules that don't contain user interface. For example, if you're creating a Reactive Web App, you can add a blank module to avoid referencing OutSystems UI.
