components.json

The components.json file holds configuration for your project.

We use it to understand how your project is set up and how to generate components customized for your project.

You can create a components.json file in your project by running the following command:

npx rrf-shadcn-ui@latest init

See the CLI section for more information.

$schema

You can see the JSON Schema for components.json here.

{
  "$schema": "https://ui.shadcn.com/schema.json"
}

style

The style for your components. This cannot be changed after initialization.

{
  "style": "default" | "new-york"
}

tailwind

Configuration to help the CLI understand how Tailwind CSS is set up in your project.

See the installation section for how to set up Tailwind CSS.

tailwind.config

Path to where your tailwind.config.js file is located.

{
  "tailwind": {
    "config": "tailwind.config.js" | "tailwind.config.ts"
  }
}

tailwind.css

Path to the CSS file that imports Tailwind CSS into your project.

{
  "tailwind": {
    "css": "styles/global.css"
  }
}

tailwind.baseColor

This is used to generate the default color palette for your components. This cannot be changed after initialization.

{
  "tailwind": {
    "baseColor": "gray" | "neutral" | "slate" | "stone" | "zinc"
  }
}

tailwind.cssVariables

You can choose between using CSS variables or Tailwind CSS utility classes for theming.

To use utility classes for theming set tailwind.cssVariables to false. For CSS variables, set tailwind.cssVariables to true.

{
  "tailwind": {
    "cssVariables": `true` | `false`
  }
}

For more information, see the theming docs.

This cannot be changed after initialization. To switch between CSS variables and utility classes, you'll have to delete and re-install your components.

tailwind.prefix

The prefix to use for your Tailwind CSS utility classes. Components will be added with this prefix.

{
  "tailwind": {
    "prefix": "tw-"
  }
}

rsc

Whether or not to enable support for React Server Components.

The CLI automatically adds a use client directive to client components when set to true.

{
  "rsc": `true` | `false`
}

tsx

Choose between TypeScript or JavaScript components.

Setting this option to false allows components to be added as JavaScript with the .jsx file extension.

{
  "tsx": `true` | `false`
}

aliases

The CLI uses these values and the paths config from your tsconfig.json or jsconfig.json file to place generated components in the correct location.

Path aliases have to be set up in your tsconfig.json or jsconfig.json file.

aliases.utils

Import alias for your utility functions.

{
  "aliases": {
    "utils": "@/lib/utils"
  }
}

aliases.components

Import alias for your components.

{
  "aliases": {
    "components": "@/components"
  }
}

aliases.ui

Import alias for ui components.

The CLI will use the aliases.ui value to determine where to place your ui components. Use this config if you want to customize the installation directory for your ui components.

{
  "aliases": {
    "ui": "@/app/ui"
  }
}
