pandatail

A PandaCSS preset that mirrors every token in your Tailwind v4 @theme { … } block into typed Panda style props.

Install

npm install -D @dmisdm/pandatail

Then install Panda itself if you don't have it:

npm install -D @pandacss/dev
npx panda init --postcss

• Tailwind owns the values; Panda owns the typed API. There is no value duplication — every Panda token resolves to var(--<tailwind-name>).
• Default Tailwind palettes (blue.500, mauve.300, …) and your custom @theme additions (brand.500, --radius-pill, …) are typed automatically.
• Tailwind utilities and Panda style props coexist in the same JSX. Refactor one side at a time.

// CSS — your @theme block is the single source of truth
@import "tailwindcss";
@theme {
  --color-brand-500: oklch(0.62 0.21 260);
  --radius-pill: 999px;
}

// TSX — Panda autocomplete & TS errors against the same tokens
<tw.span bg="brand.500" rounded="pill" px={3} py={1} color="white">
  New release
</tw.span>

Tailwind v4 (tailwindcss@^4) is a peer dependency and is loaded from your existing setup — the preset doesn't require its own copy.

Configure

// panda.config.ts
import { defineConfig } from "@pandacss/dev";
import { tailwindPresetSync } from "@dmisdm/pandatail";

export default defineConfig({
  preflight: false, // Tailwind already ships preflight
  jsxFramework: "react",
  presets: [
    "@pandacss/preset-base",
    tailwindPresetSync({ cssPath: "./src/tailwind.css" }),
  ],
  include: ["./src/**/*.{ts,tsx}"],
  outdir: "styled-system",
});

Then:

npx panda codegen

How it works

The preset reads your Tailwind entry CSS, finds every --* token inside @theme { … } blocks (including the ones Tailwind itself ships in tailwindcss/theme.css), and registers each one as a Panda token whose value is a var() reference back to the CSS variable.

Namespaces map to Panda categories:

| Tailwind namespace | Panda category | | ------------------ | ----------------------------------- | | --color-* | colors | | --spacing-* | spacing + sizes | | --radius-* | radii | | --shadow-* | shadows | | --text-* | fontSizes | | --font-* | fonts | | --font-weight-* | fontWeights | | --leading-* | lineHeights | | --tracking-* | letterSpacings | | --breakpoint-* | theme.breakpoints (media queries) | | --container-* | sizes |

Tailwind derives numeric scales (p-4, leading-6) from the single --spacing token; the preset synthesises those steps into Panda's spacing, sizes, and lineHeights categories so the typed APIs match Tailwind's coverage.

API

import {
  tailwindPreset, // async — uses Tailwind's design-system loader
  tailwindPresetSync, // sync — call from panda.config.ts (recommended)
  extractTokens,
  extractTokensSync,
} from "@dmisdm/pandatail";

Use tailwindPresetSync in panda.config.ts — Panda bundles configs to CJS and rejects top-level await.
