defaultColors is the Neutral theme of shadcn, you can also pass your own color variables, and the remaining variables will be merged with defaultColors. The values in overrides have a higher priority than those in defaults.

defineTheme

The function of defining themes. You can pass in your own color variables, or use the built-in defaultColors as defaults. You can also use inferThemeFromColor below to generate a theme as defaults.

export declare function defineTheme(options: DefineThemeOptions): Theme;

export interface DefineThemeOptions {
  defaults: AcceptableTheme;
  overrides?: Partial<AcceptableTheme>;
}

export type AcceptableTheme = {
  colors: Partial<Record<ColorKeywords, Color | string>>;
} & {
  [key in ShapeKeywords]?: string
};

export type Theme = {
  colors: Record<ColorKeywords, Color>;
} & {
  [key in ShapeKeywords]: string;
};

inferThemeFromColor

Auto generate a theme from a primary color.

export declare function inferThemeFromColor(themeColor: string): Theme;

Preset

@bernankez/theme-generator adapts to different UI frameworks through presets. It currently exports presetNone and presetShadcn. You can adapt your own UI framework through preset.

presetNone

export declare function presetNone(theme: Theme, options?: PresetNoneOptions): { theme: Theme; style: { light: Record<string, string>; dark: Record<string, string> }; unocss: Theme; tailwind: TailwindTheme };

export interface PresetNoneOptions {
  cssPrefix?: string;
}

presetShadcn

export declare function presetShadcn(theme: Theme, options?: PresetShadcnOptions): { theme: ShadcnTheme; style: { light: Record<string, string>; dark: Record<string, string> }; unocss: Theme; tailwind: TailwindTheme };

export interface PresetShadcnOptions {
  cssPrefix?: string;
}
