/ago-react - Build a Custom AGO Chat UI in React

Creates a custom chat interface using AGO SDK React hooks.

Usage

/ago-react [page-path]

Example: /ago-react src/pages/Support.tsx

Steps

1. Verify prerequisites

• Check that @useago/sdk is installed (if not, suggest /ago-setup)
• Check that AgoProvider wraps the app (if not, add it)

2. Ask what the user needs

Options range from simple to advanced:

• Drop-in widget: Pre-built <ChatWidget /> component
• Custom chat page: Full page with message list, input, conversation sidebar
• Embedded chat: Chat panel inside an existing page

3. Generate the appropriate integration

Option A: Drop-in ChatWidget (simplest)

import { ChatWidget } from "@useago/sdk/react";

export function SupportPage() {
  return (
    <ChatWidget
      agentId="your-agent-id"       // Optional: specific agent
      placeholder="Ask a question..."
      welcomeMessage="Hi! How can I help?"
    />
  );
}

Option B: Custom Chat with useChat (recommended)

import { useChat } from "@useago/sdk/react";
import type { AgoMessage } from "@useago/sdk";

export function ChatPage() {
  const {
    messages,
    isLoading,
    sendMessage,
    conversationId,
    conversations,
    selectConversation,
    startNewConversation,
  } = useChat();

  const [input, setInput] = useState("");

  const handleSend = async () => {
    if (!input.trim()) return;
    const text = input;
    setInput("");
    await sendMessage(text);
  };

  return (
    <div className="flex h-screen">
      {/* Sidebar: conversation list */}
      <aside className="w-64 border-r overflow-y-auto">
        <button onClick={startNewConversation}>New conversation</button>
        {conversations.map((conv) => (
          <button
            key={conv.id}
            onClick={() => selectConversation(conv.id)}
            className={conv.id === conversationId ? "bg-gray-100" : ""}
          >
            {conv.title || "Untitled"}
          
        ))}
      

      {/* Main chat area */}
      
        
          {messages.map((msg) => (
            
          ))}
          {isLoading && Thinking...}
        

         { e.preventDefault(); handleSend(); }} className="p-4 border-t flex gap-2">
           setInput(e.target.value)}
            placeholder="Type a message..."
            className="flex-1 border rounded px-3 py-2"
          />
          Send
        
      
    
  );
}

 () {
   isUser = message. === ;
   (
    
  );
}

Option C: Streaming with event listeners (advanced)

import { useAgoClient } from "@useago/sdk/react";
import { onMessageChunk, onMessage } from "@useago/sdk";

function useStreamingChat() {
  const client = useAgoClient();
  const [streamingContent, setStreamingContent] = useState("");

  useEffect(() => {
    const unsubChunk = onMessageChunk(client, (data) => {
      setStreamingContent((prev) => prev + data.content);
    });
    const unsubComplete = onMessage(client, () => {
      setStreamingContent("");
    });
    return () => { unsubChunk(); unsubComplete(); };
  }, [client]);

  return { streamingContent };
}

4. Handle tool calls (forms & confirmations)

If the agent uses tools that require user input:

function ToolCallHandler({ toolCall }: { toolCall: ToolCallData }) {
  const client = useAgoClient();

  if (toolCall.type === "form") {
    return (
      <form onSubmit={async (e) => {
        e.preventDefault();
        const formData = Object.fromEntries(new FormData(e.currentTarget));
        await client.submitToolCallForm(toolCall.id, formData);
      }}>
        {toolCall.formSchema?.fields.map((field) => (
          <input key={field.name} name={field.name} placeholder={field.label} required={field.required} />
        ))}
        <button type="submit">Submit</button>
      </form>
    );
  }

  if (toolCall.type === "confirmation_input") {
    return (
      <div>
        <p>{toolCall.toolDisplayName}</p>
        <button onClick={() => client.confirmToolCall(toolCall.id)}>Confirm</button>
        <button onClick= => client.rejectToolCall(toolCall.id)}>Cancel
      
    );
  }

   ;
}

5. Handle feedback

function FeedbackButtons({ messageId }: { messageId: string }) {
  const client = useAgoClient();
  return (
    <div>
      <button onClick={() => client.submitFeedback(messageId, "positive")}>👍</button>
      <button onClick={() => client.submitFeedback(messageId, "negative")}>👎</button>
    </div>
  );
}

Available React Hooks

Hook	Purpose
useChat(options?)	All-in-one: messages, conversations, sending, streaming
useMessages(options?)	Message list and sending only
useConversation(options?)	Single conversation data
useAgoClient()	Access the raw AgoClient instance
useAgoFunction(name, options)	Register a client-side function
useAgoNavigation(navigate, routes)	Register navigation routes

Checklist

1. AgoProvider wraps the component tree
2. Environment variables are set for API key and widget ID
3. Messages render both user and assistant roles
4. Loading state is shown during streaming
5. Run typecheck and lint
