packages/ui

Supabase's shared React component library. Built on Radix UI primitives and shadcn/ui, styled with Tailwind CSS, and used across all Supabase apps.

Usage

Import from the 'ui' package alias:

import { Badge, Button, Input } from 'ui'

Some of the components have the _Shadcn_ suffix. These components should be preferred, they're in a process of replacing the other ones.

Utilities

// deep object merge (used for themes)
import { clipboard, cn, mergeDeep } from 'ui' // clsx + tailwind-merge

// copy-to-clipboard helper

Styling conventions

  • Tailwind only — no inline styles or CSS modules.
  • Use shadcn semantic pairs (bg-card text-card-foreground, bg-muted text-muted-foreground, bg-tertiary text-tertiary-foreground) rather than hardcoded colors. Legacy utilities such as text-foreground-light and border-default are compatibility aliases only.
  • Themes set the core --hue (or the split --surface-hue / --primary-hue), --chroma, --surface, --foreground-lightness, and --contrast inputs, plus their --muted-foreground-level and --tertiary-foreground-level hierarchy. Semantic colors are derived from them in OKLCH; --contrast: 1 is the baseline and the supported adjustment range is 0.75 to 1.25.
  • The workspace root owns the actual tailwind.config.js. The file in this package is a stub for IntelliSense only.
