What is meant by a Fragile Frontend in Liferay?

A Fragile Frontend in Liferay refers to a frontend that breaks easily with updates. This concept highlights the challenges faced when making changes to a frontend system that hasn't been designed with robustness or flexibility in mind. When a frontend is fragile, even minor updates or modifications can lead to unexpected behaviors or failures in the application. This situation often arises from tightly coupled designs or reliance on specific implementations that may change over time.

Robust frontends are typically built with best practices that promote maintainability and adaptability. They might use modern frameworks and architectures which ensure that updates or changes are less likely to disrupt existing functionalities. By contrast, a fragile frontend can lead to increased maintenance overhead, diminished user experience, and a requirement for more frequent debugging and troubleshooting.

The other options describe characteristics that are not associated with the concept of a Fragile Frontend. High performance and user-friendliness are related to good practices and design but do not address fragility. Extensive coding does not inherently relate to fragility; rather, it’s the quality of code and design practices that determine if a frontend is fragile or not.
