聊天推理

可折叠GitHub
显示可折叠的AI推理或思维过程。

用法

ChatReasoning组件呈现一个可折叠的块，显示AI推理或思考内容。它在流式传输期间自动打开，并在流式传输后自动关闭。

<script setup lang="ts">
const streaming = ref(false)
const text = ref('')

async function simulateStreaming() {
  streaming.value = true
  text.value = ''

  const content =
    'The user is asking about Vue components. I should explain the Composition API pattern and how it relates to their question about reactive state management. Let me think about the best way to structure this response.\n\nFirst, I need to consider the key differences between the Options API and Composition API. The Composition API was introduced in Vue 3 to address limitations of the Options API when building large-scale applications.\n\nFor reactive state management specifically, the Composition API offers ref() for primitive values and reactive() for objects.'

  for (const char of content) {
    text.value += char
    await new Promise((resolve) => setTimeout(resolve, 10))
  }

  streaming.value = false
}

onMounted(simulateStreaming)
</script>

<template>
  <UChatReasoning :text="text" :streaming="streaming" class="w-60" />
</template>
<script setup lang="ts">
import { ref, reactive, onMounted } from 'vue'

const streaming = ref(false)
const text = ref('')

async function simulateStreaming() {
  streaming.value = true
  text.value = ''

  const content =
    'The user is asking about Vue components. I should explain the Composition API pattern and how it relates to their question about reactive state management. Let me think about the best way to structure this response.\n\nFirst, I need to consider the key differences between the Options API and Composition API. The Composition API was introduced in Vue 3 to address limitations of the Options API when building large-scale applications.\n\nFor reactive state management specifically, the Composition API offers ref() for primitive values and reactive() for objects.'

  for (const char of content) {
    text.value += char
    await new Promise((resolve) => setTimeout(resolve, 10))
  }

  streaming.value = false
}

onMounted(simulateStreaming)
</script>

<template>
  <UChatReasoning :text="text" :streaming="streaming" class="w-60" />
</template>
body内容使用useScrollShadow组合工具在溢出时应用渐变阴影。

Text

使用text属性设置推理内容，文本显示在可折叠的正文中。

<template>
  <UChatReasoning text="The user is asking about Vue components..." />
</template>

流媒体

使用streaming prop来表示主动推理。该组件在流式传输开始时自动打开，在流式传输结束时自动关闭。

The user is asking about Vue components...
<template>
  <UChatReasoning streaming text="The user is asking about Vue components..." />
</template>
使用@nuxt/ui/utils/ai中的isPartStreaming实用程序确定当前是否正在流式传输部件。

Shimmer

在流式传输时，触发器标签使用ChatShimmer组件。使用shimmer道具可以自定义其duration和spread。

The user is asking about Vue components...
<template>
  <UChatReasoning
    streaming
    text="The user is asking about Vue components..."
    :shimmer="{
      duration: 2,
      spread: 2
    }"
  />
</template>

Icon

使用icon道具在触发器旁边显示Icon组件。

<template>
  <UChatReasoning icon="i-lucide-brain" text="The user is asking about Vue components..." />
</template>

雪佛龙

使用chevron道具改变V形图标的位置。

当chevron被设置为leading和icon时，图标在悬停和打开时与V形符号交换。
<template>
  <UChatReasoning
    chevron="leading"
    icon="i-lucide-brain"
    text="The user is asking about Vue components..."
  />
</template>

Chevron图标

使用chevron-icon道具将chevron Icon.exe自定义为i-lucide-chevron-down。

<template>
  <UChatReasoning
    chevron-icon="i-lucide-arrow-down"
    text="The user is asking about Vue components..."
  />
</template>
你可以在你的app.config.ts中的ui.icons.chevronDown键下全局自定义这个图标。
你可以在你的ui.icons.chevronDown键下的vite.config.ts中全局自定义这个图标。
