Components developed and reviewed in isolation, with every state visible rather than only the happy one.
Any component library that more than one team will use, and any design system that has to survive its authors. The empty, loading and error states are the ones nobody remembers to check, and this is where they become visible early enough to matter.
A small application with a dozen components. Maintaining a second surface costs more than it returns at that size. It is a standing maintenance commitment, and a Storybook that has drifted from the application is worse than none because it is confidently wrong.
Loading, empty, error and overflow states as first-class stories, plus accessibility checks run against them in the pipeline. Stories cover the states that are awkward to reach in the running application, so a contrast or focus defect is caught at the component rather than in an audit at the end.
Where this appears on the site
We work in Storybook, and no case study or service page currently published on this site prints it in its stack. Rather than describe an engagement you cannot check, this space stays empty until one does. Ask us and we will talk you through it directly.
Tell us what it is running, what it costs you today, and what you need it to do next. A senior engineer will tell you what we would keep and what we would change.
