ChatBotKit Next.js SDK

The ChatBotKit SDK for Next.js is crafted to integrate chatbot functionalities seamlessly into Next.js applications, specifically optimized for Next.js Edge runtime environments.

Why ChatBotKit?

Build lighter, future-proof AI agents. When you build with ChatBotKit, the heavy lifting happens on our servers-not in your application. This architectural advantage delivers:

• 🪶 Lightweight Agents: Your agents stay lean because complex AI processing, model orchestration, and tool execution happen server-side. Less code in your app means faster load times and simpler maintenance.

• 🛡️ Robust & Streamlined: Server-side processing provides a more reliable experience with built-in error handling, automatic retries, and consistent behavior across all platforms.

• 🔄 Backward & Forward Compatible: As AI technology evolves-new models, new capabilities, new paradigms-your agents automatically benefit. No code changes required on your end.

• 🔮 Future-Proof: Agents you build today will remain capable tomorrow. When we add support for new AI models or capabilities, your existing agents gain those powers without any updates to your codebase.

This means you can focus on building great user experiences while ChatBotKit handles the complexity of the ever-changing AI landscape.

Streaming Example for Next.js Edge Runtime

The following example showcases how to implement a chatbot in a Next.js application using the Edge runtime environment.

Server-Side Code

// file: ./pages/api/conversation/complete.js
import { stream } from '@chatbotkit/next/edge'
import { ChatBotKit } from '@chatbotkit/sdk'

const cbk = new ChatBotKit({
  secret: process.env.CHATBOTKIT_API_SECRET,
})

export default async function handler(req) {
  const { messages } = await req.json()

  return stream(cbk.conversation.complete(null, { messages }))
}

export const config = {
  runtime: 'edge',
}

Client-Side Code

// file: ./pages/index.js
import { AutoTextarea, useConversationManager } from '@chatbotkit/react'

export default function Index() {
  const {
    thinking,

    text,
    setText,

    messages,

    submit,
  } = useConversationManager({
    endpoint: '/api/conversation/complete',
  })

  function handleOnKeyDown(event) {
    if (event.keyCode === 13) {
      event.preventDefault()

      submit()
    }
  }

  return (
    <div style={{ fontFamily: 'monospace', padding: '10px' }}>
      {messages.map(({ id, type, text }) => (
        <div key={id}>
          <strong>{type}:</strong> {text}
        </div>
      ))}
      {thinking && (
        <div key="thinking">
          <strong>bot:</strong> thinking...
        </div>
      )}
      <AutoTextarea
        value={text}
        onChange={(e) => setText(e.target.value)}
        onKeyDown={handleOnKeyDown}
        placeholder="Type something..."
        style={{
          border: 0,
          outline: 'none',
          resize: 'none',
          width: '100%',
          marginTop: '10px',
        }}
      />
    </div>
  )
}
