What is a 'web block' in OutSystems?

In OutSystems, a 'web block' is essentially a reusable UI component. This allows developers to create sections of a user interface that can be designed once and then reused multiple times throughout an application. The primary advantage of using web blocks is to promote consistency in design and functionality, enabling easier maintenance and updates.

When developers want to encapsulate a set of UI elements and their behavior, they can package them into a web block, allowing different screens or applications to leverage the same code. This not only saves time in development but also ensures that any changes to the block need to be made in only one location, automatically reflecting in all instances where that web block is used.

By utilizing web blocks effectively, developers can create modular and organized applications, enhancing the user experience and streamlining the development process. Other options provided, such as a database query, API integration point, or custom authentication method, do not fit the definition of a web block, which is specifically centered around UI composition and reusability.
