Should a one-person dev team use Storybook?

I built a fairly complex dashboard app on my own. At the beginning, Storybook would have felt like another thing to set up and maintain. I could run the app, open the screen I was working on, and see what I needed to see.

Then the app grew. There was an overview and several reporting screens. The same filters appeared in different contexts. Charts had to handle full datasets, sparse datasets, gaps, and no data at all. With each new screen, it got harder to answer a simple question: does this component still behave properly everywhere I use it?

That was when Storybook became useful to me. I don't think I needed it on day one. By the time the dashboard had three or more screens, I was glad to have a place where I could see the components I'd built without navigating around the whole app.

The expensive part was finding the right state

Opening a component in the running app sounds easy until the state you need depends on a particular date range, a particular dataset, or a combination of filters. Sometimes the state you most need to check is one that's difficult to produce on demand.

Take a trend chart. A year of data can look fine while a single populated month, a gap in the middle, or a very narrow layout reveals a problem. “No observations” and “observations with a result of zero” may also need different treatment. If I only looked at the happy path in the app, I could miss those distinctions.

In Storybook I can put those cases next to each other. A small, illustrative pair of stories makes the difference explicit:

export const NoObservations: Story = {
  args: { totalAudits: 0, overallCompliance: null },
}

export const MeasuredZero: Story = {
  args: { totalAudits: 33, overallCompliance: 0 },
}

The exact inputs depend on the component, of course. The useful part is that each state has a name and can be opened again tomorrow. I don't have to remember which sequence of clicks produced it.

A component library for an audience of one

When people talk about Storybook, they often talk about sharing components with designers or other developers. That can be valuable, but it wasn't my reason for adopting it. I wanted a reliable way to inspect my own work as the app grew.

The stories started with individual components, including a chart, and expanded to shared filters and whole report page compositions. Seeing a filter on its own helps, but seeing it in the overview and on different report screens catches a different class of problem. Long labels, selected filters, reset states, and narrow layouts are easier to revisit when they each have a story.

It also helps that the stories use fixed example data. I can open a component without signing in or waiting for the backend to contain the right records. That makes visual changes quicker to inspect. I still check the running app for real data flow and integration; a story only shows the scenario I gave it.

When would I add it again?

I wouldn't set a rule that every solo project needs Storybook. For a small app with one or two straightforward screens, opening the app may be the fastest way to work.

I'd consider adding it when I repeatedly spend time recreating the same component state, when components appear across several screens, or when edge cases are easy to overlook. Start with the component that's causing the friction. You can add stories for other components as the need becomes clear.

So, should a one-person dev team use Storybook? For my dashboard, eventually, yes. The number of developers wasn't the deciding factor. The number of screens, states, and repeated checks was.
