## 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.

## SDK Features

- **Easy Setup**: Quick and straightforward installation process.
- **Serverless Compatibility**: Works seamlessly with modern runtime environments like Serverless, Edge, Vercel, Netlify, Cloudflare Workers, Deno, AWS Lambda, and more.
- **Modern Framework Support**: Built-in support for CommonJS, ECMAScript Modules, async/await, streams, etc.
- **Customizability**: Tailor the chatbot’s behavior and responses to fit specific use cases.
- **Multi-Platform**: Deploy chatbots on websites, mobile apps, and messaging platforms like Slack, Discord, and WhatsApp.
- **Multi-Model**: Support for a wide range of language models, including GPT-3, GPT-4, Claude, and more.

## Getting Started

Follow these steps to start with ChatBotKit:

1. **Installation**:
   ```bash
   npm install @chatbotkit/sdk
   ```
2. **Usage**: Implement the SDK in your chatbot project.

### Streaming Example

This example demonstrates streaming capabilities in Edge and Serverless environments:

```javascript
import { ConversationClient } from '@chatbotkit/sdk/conversation/index.js'

const client = new ConversationClient(/* configuration */)

for await (const { type, data } of client
  .complete(null, { model: 'gpt-4', messages })
  .stream()) {
  if (type === 'token') {
    process.stdout.write(data.token)
  }
}
```

### NextGen Example for Next.js

This example showcases how to build advanced conversational AI with streaming,
function calls, server-side rendering and much more in a Next.js project:

```javascript
// file: ./app/page.jsx
import ChatArea from '../components/ChatArea.jsx'

export default function Page() {
  return <ChatArea />
}

// file: ./components/ChatArea.jsx
'use client'

import { useContext } from 'react'

import { complete } from '../actions/conversation.jsx'

import { ChatInput, ConversationContext } from '@chatbotkit/react'
import ConversationManager from '@chatbotkit/react/components/ConversationManager'

export function ChatMessages() {
  const {
    thinking,

    text,
    setText,

    messages,

    submit,
  } = useContext(ConversationContext)

  return (
    <div>
      <div>
        {messages.map(({ id, type, text, children }) => {
          switch (type) {
            case 'user':
              return (
                <div key={id}>
                  <div>
                    <strong>user:</strong> {text}
                  </div>
                </div>
              )

            case 'bot':
              return (
                <div key={id}>
                  <div>
                    <strong>bot:</strong> {text}
                  </div>
                  {children ? <div>{children}</div> : null}
                </div>
              )
          }
        })}
        {thinking ? (
          <div key="thinking">
            <strong>bot:</strong> thinking...
          </div>
        ) : null}
      </div>
      <ChatInput
        value={text}
        onChange={(e) => setText(e.target.value)}
        onSubmit={submit}
        placeholder="Type something..."
        style={{
          border: 0,
          outline: 'none',
          resize: 'none',
          width: '100%',
          marginTop: '10px',
        }}
      />
    </div>
  )
}

export default function ChatArea() {
  return (
    <ConversationManager endpoint={complete}>
      <ChatMessages />
    </ConversationManager>
  )
}

// file: ./actions/conversation.jsx
'use server'

import CalendarEvents from '../components/CalendarEvents.jsx'

import { streamComplete } from '@chatbotkit/react/actions/complete'
import { ChatBotKit } from '@chatbotkit/sdk'

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

export async function complete({ messages }) {
  return streamComplete({
    client: cbk.conversation,

    messages,

    functions: [
      {
        name: 'getUserName',
        description: 'Get the authenticated user name',
        parameters: {},
        handler: async () => {
          return 'John Doe'
        },
      },

      {
        name: 'getCalendarEvents',
        description: 'Get a list of calendar events',
        parameters: {},
        handler: async () => {
          const events = [
            { id: 1, title: 'Meeting with Jane Doe' },
            { id: 2, title: 'Meeting with Jill Doe' },
          ]

          return {
            children: <CalendarEvents events={events} />,

            result: {
              events,
            },
          }
        },
      },

      {
        name: 'declineCalendarEvent',
        description: 'Decline a calendar event',
        parameters: {
          type: 'object',
          properties: {
            id: {
              type: 'number',
              description: 'The ID of the event to decline',
            },
          },
          required: ['id'],
        },
        handler: async ({ id }) => {
          return `You have declined the event with ID ${id}`
        },
      },
    ],
  })
}
```

### Basic Next.js Example

This quick example demonstrates how to use the SDK in a Next.js project:

```javascript
// 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>
  )
}

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

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',
}
```
