🚀 Quick Start

1. Dependency Management

🎯 Automatic Dependency Handling

📋 System Requirements

• @antdv-next/x-sdk: latest version (automatically installed)
• @antdv-next/x: latest version (UI components, automatically installed)

⚠️ Version Issue Auto-fix

If version mismatch is detected, the skill will automatically:

• ✅ Prompt current version status
• ✅ Provide fix suggestions
• ✅ Use relative paths to ensure compatibility

🎯 Built-in Version Check

The use-x-chat skill has built-in version checking functionality, automatically checking version compatibility on startup:

🔍 Auto-check Function The skill will automatically check if the @antdv-next/x-sdk version meets requirements on startup:

📋 Check Contents:

• ✅ Currently installed version
• ✅ Whether it meets minimum requirements
• ✅ Automatically provide fix suggestions
• ✅ Friendly error prompts

🛠️ Version Issue Fix If version mismatch is detected, the skill will provide specific fix commands:

# Auto-prompted fix commands
npm install @antdv-next/x-sdk@latest

2. Three-step Integration

Step 1: Prepare Provider

This part is handled by the x-chat-provider skill

import { MyChatProvider } from "./MyChatProvider";
import { XRequest } from "@antdv-next/x-sdk";
// Recommended to use XRequest as the default request method
const provider = new MyChatProvider({
  // Default use XRequest, no need for custom fetch
  request: XRequest("https://your-api.com/chat"),
  // When requestPlaceholder is set, placeholder message will be displayed before request starts
  requestPlaceholder: {
    content: "Thinking...",
    role: "assistant",
    timestamp: Date.now(),
  },
  // When requestFallback is set, fallback message will be displayed when request fails
  requestFallback: (_, { error, errorInfo, messageInfo }) => {
    if (error.name === "AbortError") {
      return {
        content: messageInfo?.message?.content || "Reply cancelled",
        role: "assistant" as const,
        timestamp: Date.now(),
      };
    }
    return {
      content:
        errorInfo?.error?.message || "Network error, please try again later",
      role: "assistant" as const,
      timestamp: Date.now(),
    };
  },
});

Step 2: Basic Usage

import { defineComponent } from "vue";
import { useXChat } from "@antdv-next/x-sdk";
const ChatComponent = defineComponent(() => {
  const { messages, onRequest, isRequesting } = useXChat({ provider });
  return () => (
    <div>
      {messages.value.map(msg => (
        <div key={msg.id}>
          {msg.message.role}: {msg.message.content}
        </div>
      ))}
      <button onClick={() => onRequest({ query: "Hello" })}>Send</button>
    </div>
  );
});

Step 3: UI Integration

import { defineComponent } from "vue";
import { Bubble, Sender } from "@antdv-next/x";
import { useXChat } from "@antdv-next/x-sdk";
const ChatUI = defineComponent(() => {
  const { messages, onRequest, isRequesting, abort } = useXChat({ provider });
  return () => (
    <div style={{ height: "600px" }}>
      <Bubble.List items={messages.value} />
      <Sender
        loading={isRequesting.value}
        onSubmit={content => onRequest({ query: content })}
        onCancel={abort}
      />
    </div>
  );
});

Data Model

⚠️ Important Reminder: messages type is Ref<MessageInfo<MessageType>[]>, not direct MessageType. Access via messages.value.

interface MessageInfo<Message> {
  id: number | string; // Message unique identifier
  message: Message; // Actual message content
  status: MessageStatus; // Sending status
  extraInfo?: AnyObject; // Extended information
}
// Message status enum
type MessageStatus =
  "local" | "loading" | "updating" | "success" | "error" | "abort";

📋 Prerequisites and Dependencies

⚠️ Important Dependencies

use-x-chat must depend on one of the following skills:

🎯 Usage Scenario Comparison Table

🚨 Development Rules

Before using use-x-chat, must confirm:

• [ ] Has Provider source (choose one of the following):
• [ ] Has created custom Provider with x-chat-provider
• [ ] Decided to use built-in Provider (OpenAI/DeepSeek)
• [ ] @antdv-next/x-sdk is installed
• [ ] Understand MessageInfo data structure
• [ ] UI components are ready

Test Case Rules

• If the user does not explicitly need test cases, do not add test files
• Only create test cases when the user explicitly requests them

Code Quality Rules

• After completion, must check types: Run tsc --noEmit to ensure no type errors
• Keep code clean: Remove all unused variables and imports
