## Overview

Theme configuration is used to customize various features of the theme and control its behavior.
You can configure it in either `.vuepress/config.ts` or `.vuepress/plume.config.ts`.

When a field description includes the following statement, it indicates that the field is not supported for configuration in `.vuepress/plume.config.ts`:

::: warning This field is not supported for configuration in the [Theme Config File `plume.config.js`](./intro.md#theme-config-file).
:::

For fields without the above declaration, you can configure them in either `.vuepress/config.ts`
or `.vuepress/plume.config.ts`. It is generally recommended to configure them in `.vuepress/plume.config.ts`.

::: warning Avoid reconfiguring a field that has already been configured in one configuration file within another configuration file.

  This configuration item addresses the slow startup speed of VuePress.
  It caches the compilation results during the first service start.
  On subsequent starts, it reads the cache directly, skipping compilation to speed up startup.

  - `false`: Disable cache.
  - `'memory'`: Use memory cache. This method provides faster startup speed but increases memory usage
    as the number of project files grows. Suitable for projects with fewer articles.
  - `'filesystem'`: Use filesystem cache. This method provides a relatively fast and stable startup speed,
    more suitable for projects with substantial content.

  ::: warning
  This field is not supported for configuration in the [Theme Config File `plume.config.js`](./intro.md#theme-config-file).

  For the cache to take effect, you should **remove** the `--clean-cache` parameter from the
  `vuepress dev` development server startup script in your `package.json`.

- **Default:** `{ formatOptions: { dateStyle: 'short', timeStyle: 'short' } }`
- **Details:** Last updated time.

## Locale Configuration

::: tip All the following fields are also basic configuration fields and can be configured at the same level as fields like `locales`.
:::

### home

- **Type:** `false | string`
- **Default:** `/`

  The path to the home page. It will be used for:

- **Default:** `false`
- **Details:** Logo in the navbar.

### appearance

- **Type:** `boolean | 'dark' | 'force-dark'`
- **Default:** `true`

Whether to enable dark mode.

- If this option is set to `true`, the default theme will be determined by the user's preferred color scheme.
- If this option is set to `dark`, the theme will be dark by default unless the user manually toggles it.
- If this option is set to `false`, the user will not be able to switch themes.
- If this option is set to `force-dark`, the user will not be able to switch themes, and the theme will be forced to dark.

This option injects an inline script that restores user settings from local storage.
This ensures `[data-theme="dark"]` is applied before the page is rendered to avoid flashing.

### profile

  - `profile.avatar`: Avatar URL, used for displaying blogger information on the right.

export default defineUserConfig({
  theme: plumeTheme({
    profile: {
      avatar: '/avatar.jpg',

### navbar

- **Type:** `NavItem[]`
- **Default:** `[]`
- **Details:** Navbar configuration.

  To configure navbar elements, you can set it to a navbar array, where each element is a `string` or a `NavItem` object.

type NavItem = string | {
  text: string

   */
  prefix?: string
  /**
   * Navigation items under this group.
   */

  /**
   * Supports iconify icons. Use the iconify name directly and it will be loaded automatically.
   *
   * @see https://icon-sets.iconify.design/

  icon: string
  /**
