When to Use This Skill
✅ Use When:
- Building accessible UIs with full styling control
- Migrating from Radix UI to Base UI
- Need components with Floating UI positioning
- Want render prop pattern instead of asChild
- Building with Tailwind v4 for styling
- Deploying to Cloudflare Workers
- Creating custom design systems
- Need 100% accessibility compliance
- Comfortable with beta software (stable Q4 2025)
❌ Don't Use When:
- Need pre-styled components (use shadcn/ui, Chakra, MUI)
- Can't tolerate beta software (wait for v1.0)
- Prefer asChild pattern (stay with Radix)
- Need IE11 support (Base UI requires modern browsers)
- Building with React < 19 (Base UI requires React 19+)
- Don't need accessibility features
- Want zero configuration setup
Quick Usage Example
# 1. Install Base UI
pnpm add @base-ui-components/react
# 2. Use component with render props
import { Dialog } from "@base-ui-components/react/dialog";
<Dialog.Root>
<Dialog.Trigger
render={(props) => (
<button {...props} className="px-4 py-2 bg-blue-600 text-white rounded">
Open
</button>
)}
/>
<Dialog.Portal>
<Dialog.Backdrop render={(props) => <div {...props} className="fixed inset-0 bg-black/50" />} />
<Dialog.Popup render={(props) => (
<div {...props} className="fixed left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2 bg-white rounded-lg p-6">
<Dialog.Title render={(p) => <h2 {...p}>Title</h2>} />
<Dialog.Close render={(p) => <button {...p}>Close</button>} />
</div>
)} />
</Dialog.Portal>
</Dialog.Root>
# 3. Components needing positioning use Positioner
import { Popover } from "@base-ui-components/react/popover";
<Popover.Root>
<Popover.Trigger render={(props) => <button {...props}>Open</button>} />
<Popover.Positioner side="top" alignment="center">
<Popover.Portal>
<Popover.Popup render={(props) => <div {...props}>Content</div>} />
</Popover.Portal>
</Popover.Positioner>
</Popover.Root>
Result: Fully accessible, completely styled by you!
