Generating Reusable Web Components from Mockups

The transformation of a user interface mockup designed by a graphic designer to web components in the final app built by a web developer is often laborious, involving manual and time consuming steps. We propose an approach to automate this aspect of web development by generating reusable web components from a mockup. Our approach employs visual analysis of the mockup, and unsupervised learning of visual cues to create reusable web components (e.g., REACT components). We evaluated our approach, implemented in a tool called VIZMOD, on five real-world web mockups, and assessed the transformations and generated components through comparison with web development experts. The results show that VIZMOD achieves on average 94% precision and 75% recall in terms of agreement with the developers' assessment. Furthermore, the refactorings yielded 22% code reusability, on average.
