Numerous, sometimes complex requirements for components of design systems or component libraries would not have to be considered over and over again if there were small-scale, easily reusable basic components to carry these requirements.


Swizzling is defined as the possibility of either modifying an existing component from the outside or replacing the internal construction. Both pay off in high reusability.



The easiest method to customize a KoliBri component is wrapping. Here, an own component is built around the KoliBri component (decorator pattern) and individualized on the outside.


Another variant of swizzling is the overwriting of the inner component construction. In Web Components, this is often done using slots. In KoliBri, we have introduced the for this purpose.
