Changelog

[0.34.0] - 2024-03-06

Fixed

• Fix issue where text accent color token was nested incorrectly.
• Fix splitCssProps typings, it would sometimes throw Expression produces a union type that is too complex to represent"
• Fix "missing token" warning when using DEFAULT in tokens path

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  validation: 'error',
  theme: {
    semanticTokens: {
      colors: {
        primary: {
          DEFAULT: { value: '#ff3333' },
          lighter: { value: '#ff6666' },
        },
        background: { value: '{colors.primary}' }, // <-- ⚠️ wrong warning
        background2: { value: '{colors.primary.lighter}' }, // <-- no warning, correct
      },
    },
  },
})

Added

• Add a config validation check to prevent using spaces in token keys, show better error logs when there's a CSS parsing error
• Add a warning when using value twice in config

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  validation: 'error',
  theme: {
    tokens: {
      colors: {
        primary: { value: '#ff3333' },
      },
    },
    semanticTokens: {
      colors: {
        primary: {
          value: { value: '{colors.primary}' }, // <-- ⚠️ new warning for this
        },
      },
    },
  },
})

• Allow using the color opacity modifier syntax (blue.300/70) in token references:

1. {colors.blue.300/70}
2. token(colors.blue.300/70)

Note that this works both in style usage and in build-time config.

// runtime usage

import { css } from '../styled-system/css'

css({ bg: '{colors.blue.300/70}' })
// => @layer utilities {
//    .bg_token\(colors\.blue\.300\/70\) {
//      background: color-mix(in srgb, var(--colors-blue-300) 70%, transparent);
//    }
//  }

css({ bg: 'token(colors.blue.300/70)' })
// => @layer utilities {
//    .bg_token\(colors\.blue\.300\/70\) {
//      background: color-mix(in srgb, var(--colors-blue-300) 70%, transparent);
//    }
//  }

// build-time usage
import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  theme: {
    tokens: {
      colors: {
        blue: {
          300: { value: '#00f' },
        },
      },
    },
    semanticTokens: {
      colors: {
        primary: {
          value: '{colors.blue.300/70}',
        },
      },
    },
  },
})

@layer tokens {
  :where(:root, :host) {
    --colors-blue-300: #00f;
    --colors-primary: color-mix(in srgb, var(--colors-blue-300) 70%, transparent);
  }
}

Changed

Deprecates emitPackage, it will be removed in the next major version.

Why?

It's known for causing several issues:

• bundlers sometimes eagerly cache the node_modules, leading to panda codegen updates to the styled-system not visible in the browser
• auto-imports are not suggested in your IDE.
• in some IDE the typings are not always reflected properly

As alternatives, you can use:

• relative paths instead of absolute paths (e.g. ../styled-system/css instead of styled-system/css)
• use package.json #imports and/or tsconfig path aliases (prefer package.json#imports when possible, TS 5.4 supports them by default) like #styled-system/css instead of styled-system/css
• for a component library, use a dedicated workspace package (e.g. @acme/styled-system) and use importMap: "@acme/styled-system" so that Panda knows which entrypoint to extract, e.g. import { css } from '@acme/styled-system/css'
