Presets

预加载 Presets 是部分配置，将合并到主配置中。

当创作预加载 Preset 时，我们通常导出一个构造函数，你可以要求一些特定于预加载 Preset 的选项。例如：

// my-preset.ts
import { Preset, definePreset } 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
  }
})

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 */ }),
  ],
})

You can check official presets and community presets for more examples.
