Basic

Inline Code

Use inline code to display code snippets within text paragraphs. It's ideal for referencing code elements directly in sentences.

::code-preview

class: "[&>div]:*:my-0"

inline code

#code

`inline code`

::

Code Blocks

Use code blocks to display multi-line code snippets with syntax highlighting. Code blocks are essential for presenting code examples clearly.

::code-preview

class: "[&>div]::my-0 [&>div]::w-full"

export default defineNuxtConfig({
  modules: ['@nuxt/ui-pro']
})

#code

```ts
export default defineNuxtConfig({
  modules: ['@nuxt/ui-pro']
})
```

::

When writing a code-block, you can specify a filename that will be displayed on top of the code block. An icon will be automatically displayed based on the extension or the name. Filenames help users understand the code's location and purpose within a project.

::code-preview

class: "[&>div]::my-0 [&>div]::w-full"

export default defineNuxtConfig({
  modules: ['@nuxt/ui-pro']
})

#code

```ts [nuxt.config.ts]
export default defineNuxtConfig({
  modules: ['@nuxt/ui-pro']
})
```

::

Every code-block has a built-in copy button that will copy the code to your clipboard.

::tip{to="https://ui.nuxt.com/getting-started/icons/nuxt#theme"} Icons are already defined by default, but you can customize them in your app.config.ts:

export default defineAppConfig({
  uiPro: {
    prose: {
      codeIcon: {
        terminal: 'i-ph-terminal-window-duotone'
      }
    }
  }
})

::

Advanced

CodeGroup

Group code blocks in tabs using code-group. code-group is perfect for showing code examples in multiple languages or package managers.

::code-preview

class: "[&>div]::my-0 [&>div]::w-full"

:::code-group{.w-full}

  pnpm add @nuxt/ui-pro@next

  yarn add @nuxt/ui-pro@next

  npm install @nuxt/ui-pro@next

  bun add @nuxt/ui-pro@next

:::

#code

:::code-group

```bash [pnpm]
pnpm add @nuxt/ui-pro@next
```

```bash [yarn]
yarn add @nuxt/ui-pro@next
```

```bash [npm]
npm install @nuxt/ui-pro@next
```

```bash [bun]
bun add @nuxt/ui-pro@next
```

CodeTree

Display code blocks in a file tree view using code-tree. code-tree is excellent for showcasing project structures and file relationships.

::code-preview{class="[&>div]::my-0 [&>div]::w-full"} :::code-tree{default-value="app/app.config.ts"}

  export default defineNuxtConfig({
    modules: ['@nuxt/ui-pro'],
  
    future: {
      compatibilityVersion: 4
    },
  
    css: ['~/assets/css/main.css']
  })
  

  @import "tailwindcss";
  @import "@nuxt/ui-pro";

  export default defineAppConfig({
    ui: {
      colors: {
        primary: 'sky',
        colors: 'slate'
      }
    }
  })

  ```
  
  ## Development Server
  
  Start the development server on `http://localhost:3000`:
  
  ```bash
  # npm
  npm run dev
  
  # pnpm
  pnpm run dev
  
  # yarn
  yarn dev
  
  # bun
  bun run dev
  ```
  
  ## Production
  
  Build the application for production:
  
  ```bash
  # npm
  npm run build
  
  # pnpm
  pnpm run build
  
  # yarn
  yarn build
  
  # bun
  bun run build

CodePreview

Use code-preview to show code output alongside the code. code-preview is ideal for interactive examples and demonstrating code results. Write the code to be previewed in a the default slot and the actual code in the code slot.

CodeCollapse

Use code-collapse for long code blocks to keep pages clean. code-collapse allows users to expand code blocks only when needed, improving readability.

::code-preview
