Creating designs without designers
Ideally, screen designs are not done anymore. Instead, components are crafted directly by UX engineers, who do not need to hand over work for technical implementation. In such scenarios, the technical implementation of these components is already done by them.
The outcome of such setups is a pattern library that can be used by all teams. This library might be as low level as a set of CSS classes with HTML fragments and JavaScript snippets – sometimes even packaged up as Web Components – or provided already for specific frameworks. For instance, these can be shipped as a React component library.
One advantage of framework-specific libraries is that they can be used within that framework very easily, and they are usually more efficient than generic libraries that require additional embedding. The inefficiency for the latter does not come from generic JavaScript, but rather from not being able to use framework-specific optimizations...
