Quick Start (15 Minutes)

Prerequisites

• Next.js 15+ (App Router)
• shadcn/ui initialized
• Tailwind v4
• AI SDK v5+

1. Initialize

pnpm dlx ai-elements@latest init

2. Add Components

pnpm dlx ai-elements@latest add message conversation response prompt-input

3. Create Chat Interface

'use client';

import { Message } from '@/components/ui/ai/message';
import { Response } from '@/components/ui/ai/response';

export default function ChatPage() {
  const { messages, input, handleInputChange, handleSubmit } = useChat({
    api: '/api/chat'
  });

  return (
    <div className="flex h-screen flex-col">
      <Conversation>
        {messages.map((msg) => (
          <Message key={msg.id} role={msg.role}>
            <Response markdown={msg.content} />
          </Message>
        ))}
      </Conversation>

      <PromptInput

Critical Rules

Always Do ✅

1. Install shadcn/ui first (AI Elements requires it)
2. Use Next.js App Router (Pages Router not supported)
3. Use AI SDK v5 (breaking changes from v4)
4. Install via CLI (pnpm dlx ai-elements@latest)
5. Update components.json with registry
6. Use client components ('use client' directive)
7. Stream responses for better UX
8. Handle loading states
9. Add error boundaries
10. Test on mobile

Never Do ❌

1. Never install as npm package (components are copied)
2. Never use Pages Router (only App Router)
3. Never use AI SDK v4 (breaking changes)
4. Never skip prerequisites (shadcn/ui, Tailwind)
5. Never modify core types (extends shadcn types)
6. Never use without streaming (defeats purpose)
7. Never skip accessibility (ARIA labels)
8. Never hardcode styles (use Tailwind)
9. Never skip error handling (API failures)
10. Never ignore mobile (responsive required)

Common Use Cases

Use Case 1: Basic Chat

const { messages, input, handleInputChange, handleSubmit } = useChat();

return (
  <>
    <Conversation>
      {messages.map(m => (
        <Message key={m.id} role={m.role}>
          <Response markdown={m.content} />
        </Message>
      ))}
    </Conversation>
    <PromptInput value={input} onChange={handleInputChange} onSubmit={handleSubmit} />
  </>
);

Use Case 2: With Tool Calls

{messages.map(m => (
  <Message key={m.id} role={m.role}>
    {m.toolInvocations?.map(tool => (
      <Tool key={tool.toolCallId} name={tool.toolName} args={tool.args} result={tool.result} />
    ))}
    <Response markdown={m.content} />
  </Message>
))}

Use Case 3: With Reasoning

<Message role="assistant">
  {reasoning && <Reasoning content={reasoning} />}
  <Response markdown={content} />
</Message>

Use Case 4: With Code Blocks

<Response markdown={content}>
  {(node) => node.type === 'code' ? (
    <CodeBlock code={node.value} language={node.lang} />
  ) : null}
</Response>

Use Case 5: With Sources

<Message role="assistant">
  <Response markdown={content} />
  <Sources sources={sources} />
</Message>

API Routes

Basic Streaming

// app/api/chat/route.ts
import { streamText } from 'ai';
import { openai } from '@ai-sdk/openai';

export async function POST(req: Request) {
  const { messages } = await req.json();

  const result = streamText({
    model: openai('gpt-4'),
    messages
  });

  return result.toDataStreamResponse();
}

With Tools

const result = streamText({
  model: openai('gpt-4'),
  messages,
  tools: {
    search: {
      description: 'Search the web',
      parameters: z.object({ query: z.string() }),
      execute: async ({ query }) => {
        return await search(query);
      }
    }
  }
});
