Customization

Presets

By default, any configuration you add in your own panda.config.js file is smartly merged with the default configuration, allowing your override or extend specific parts of the configuration.

You can specify a preset in your panda.config.js file by using the presets option:

import { defineConfig } from '@pandacss/dev'
 
export default defineConfig({
  presets: ['@acmecorp/panda-preset'],
})

Creating a preset

Presets are also valid Panda configuration objects, taking a similar shape to the configuration you would add in your panda.config.ts file.

// my-preset.js
import { definePreset } from "@pandacss/dev";
 
export default definePreset({
  theme: {
    tokens: {
      colors: {
        rose: {
          50: { value: "#fff1f2" },
          // ...
          800: { value: "#9f2233" },
        },
      },
    },
  }
});

You can then use this preset in your panda.config.ts file:

// panda.config.ts
import { defineConfig } from '@pandacss/dev'
import myPreset from './my-preset'
 
export default defineConfig({
  presets: [myPreset]
})

Asynchronous presets

There are cases where you need to perform logic to determine the content of your preset, you'd call functions to do this. In cases where they're asynchronous; panda allows promises, given that they resolve to a valid preset object.

// my-preset.js
export default async function myPreset() {
  const roseColors = await getRoseColors();
 
  return definePreset({
    theme: {
      tokens: {
        colors: {
          rose: roseColors,
        },
      },
    }
  });
}

You can then use this preset in your panda.config.ts file:

// panda.config.ts
import { defineConfig } from '@pandacss/dev'
import myPreset from './my-preset'
 
export default defineConfig({
  presets: [myPreset()]
})

Which panda presets will be included ?

Visual helper

@pandacss/preset-base: ALWAYS included if NOT using eject: true
@pandacss/preset-panda: only included by default if you haven't specified the presets config option, otherwise you'll have to include that preset by yourself like so:

import pandaPreset from '@pandacss/preset-panda'
import { defineConfig } from '@pandacss/dev'
 
export default defineConfig({
  // ...
  presets: [pandaPreset, myCustomPreset]
})
