预设

🌐 Presets

预设是部分配置，将合并到主配置中。

🌐 Presets are partial configurations that will be merged into the main configuration.

在创建预设时，我们通常会导出一个构造函数，你可以通过它请求一些预设特定的选项。例如：

🌐 When authoring a preset, we usually export a constructor function that you could ask for some preset-specific options. For example:

my-preset.ts

import { definePreset, Preset } from 'unocss'

export default definePreset((options?: MyPresetOptions) => {
  return {
    name: 'my-preset',
    rules: [
      // ...
    ],
    variants: [
      // ...
    ],
    // it supports most of the configuration you could have in the root config
  }
})

然后用户可以像这样使用它：

🌐 Then the user can use it like this:

uno.config.ts

import { defineConfig } from 'unocss'
import myPreset from './my-preset'

export default defineConfig({
  presets: [
    myPreset({ /* preset options */ }),
  ],
})

你可以查看官方预设和社区预设以获取更多示例。
