任务

一个可折叠的任务列表组件，用于显示 AI 工作流进度，带有状态指示器和可选描述。

Task 组件提供了一种结构化的方式来显示任务列表或工作流进度，具有可折叠的详细信息、状态指示器和进度跟踪。它由一个主 Task 容器组成，带有用于可点击标题的 TaskTrigger 和用于可折叠内容区域的 TaskContent。

使用 CLI 安装

})

const isOpen = ref(props.defaultOpen)

function toggleOpen() {
  isOpen.value = !isOpen.value
}

provide('isOpen', isOpen)
provide('toggle', toggleOpen)
</script>

<template>

</template>

与 AI SDK 一起使用

使用 experimental_generateObject 构建模拟异步编程代理。

将以下组件添加到你的前端：

pages/index.vue

<script setup lang="ts">
import { experimental_useObject as useObject } from '@ai-sdk/vue'
import {
  SiCss,
  SiHtml5,
  SiJavascript,
  SiJson,
  SiMarkdown,
  SiTypescript,
  SiVue,
} from '@icons-pack/vue-simple-icons'
import {
  Task,
  TaskContent,
  TaskItem,
  TaskItemFile,
  TaskTrigger,
} from '@/components/ai-elements/task'
import { Button } from '@/components/ui/button'
import { tasksSchema } from '@/server/api/agent'

const iconMap = {
  vue: { component: SiVue, color: '#149ECA' },
  typescript: { component: SiTypescript, color: '#3178C6' },
  javascript: { component: SiJavascript, color: '#F7DF1E' },
  css: { component: SiCss, color: '#1572B6' },
  html: { component: SiHtml5, color: '#E34F26' },
  json: { component: SiJson, color: '#000000' },
  markdown: { component: SiMarkdown, color: '#000000' },
}

type IconKey = keyof typeof iconMap

const { object, submit, isLoading } = useObject({
  api: '/api/agent',
  schema: tasksSchema,
})

function handleSubmit(taskType: string) {
  submit({ prompt: taskType })
}
</script>

<template>
  <div class="max-w-4xl mx-auto p-6 relative size-full rounded-lg border h-[600px]">
    <div class="flex flex-col h-full">
      <div class="flex gap-2 mb-6 flex-wrap">
        <Button
          :disabled="isLoading"
          variant="outline"
          @click="handleSubmit('Vue component development')"
        >
          Vue Development
        </Button>
      </div>

      <div class="flex-1 overflow-auto space-y-4">
        <div v-if="isLoading && !object" class="text-muted-foreground">
          Generating tasks...
        </div>

        <Task
          v-for="(task, taskIndex) in object?.tasks"
          :key="taskIndex"
          :default-open="taskIndex === 0"
        >
          <TaskTrigger :title="task.title || 'Loading...'" />
          <TaskContent>
            <TaskItem v-for="(item, itemIndex) in task.items" :key="itemIndex">
              <template v-if="item?.type === 'file' && item.file && iconMap[item.file.icon as IconKey]">
                <span class="inline-flex items-center gap-1">
                  {{ item.text }}
                  <TaskItemFile>
                    <component
                      :is="iconMap[item.file.icon as IconKey].component"
                      :color="item.file.color || iconMap[item.file.icon as IconKey].color"
                      class="size-4"
                    />
                    <span>{{ item.file.name }}</span>
                  </TaskItemFile>
                </span>
              </template>
              <template v-else>
                {{ item?.text || '' }}
              </template>
            </TaskItem>
          </TaskContent>
        </Task>
      </div>
    </div>
  </div>
</template>

将以下路由添加到你的后端：

server/api/agent.ts

import { streamObject } from 'ai'
import { z } from 'zod'

const taskItemSchema = z.object({
  type: z.enum(['text', 'file']),
  text: z.string(),
  file: z
    .object({
      name: z.string(),
      icon: z.string(),
      color: z.string().optional(),
    })
    .optional(),
})

const taskSchema = z.object({
  title: z.string(),
  items: z.array(taskItemSchema),
  status: z.enum(['pending', 'in_progress', 'completed']),
})

const tasksSchema = z.object({
  tasks: z.array(taskSchema),
})

export const maxDuration = 30

export default defineEventHandler(async (event) => {
  const body = await readBody<{ prompt: string }>(event)

  const result = streamObject({
    model: 'openai/gpt-4o',
    schema: tasksSchema,
    prompt: `You are an AI assistant that generates realistic development task workflows. Generate a set of tasks that would occur during ${body.prompt}.
            Each task should have:
            - A descriptive title
            - Multiple task items showing the progression
            - Some items should be plain text, others should reference files
            - Use realistic file names and appropriate file types
            - Status should progress from pending to in_progress to completed
            For file items, use these icon types: 'vue', 'typescript', 'javascript', 'css', 'html', 'json', 'markdown'
            Generate 3-4 tasks total, with 4-6 items each.`,
  })

  return result.toTextStreamResponse()
})
