## Installation

### NPM

To install the package, run the following command:

```bash
npm i alpha-ai-avatar-sdk-js
```

### Minified JS

To use the SDK without a package manager, you can include it with a script tag:

```javascript
<script src='https://unpkg.com/alpha-ai-avatar-sdk-js/index.js'></script>
```

The module will be exported under `Avatar` in the global namespace. When accessing symbols from the class, you'd need to prefix them with `Avatar.` For example, `AvatarClient` becomes `Avatar.AvatarClient`.

## Usage

### Importing and Initializing

To get started, first import the AvatarClient from the SDK:

```javascript
import { AvatarClient } from 'alpha-ai-avatar-sdk-js';
```

Next, initialize `AvatarClient` outside the component with your configuration. Replace `YOUR_API_KEY` with the API key provided by our team:

```javascript
const client = new AvatarClient({ apiKey: 'YOUR_API_KEY' });
```

#### Available Options

- `apiKey` (required): Your API key for authentication.
- `baseUrl` (optional): Send `'https://staging.avatar.alpha.school'` to use the staging environment. Defaults to the production URL.

### Integrating with React

Example of a code integrating with a React app.

```javascript
import { AvatarClient } from 'alpha-ai-avatar-sdk-js';
import { Button } from './Button';
import React, { useEffect, useState } from 'react';

const avatar = new AvatarClient({
  apiKey: 'API_KEY',
});

export function App() {
  const [isConnected, setIsConnected] = useState(avatar.isConnected);

  const videoRef = React.useRef < HTMLVideoElement > null;
  const audioRef = React.useRef < HTMLAudioElement > null;

  useEffect(() => {
    if (videoRef.current && audioRef.current) {
      avatar.init({
        videoElement: videoRef.current
      }, audioRef.current);
    }
    return () => {
      avatar.disconnect();
    };
  }, []);

  return (
    <div
      style={{
        display: 'flex',
        alignItems: 'center',
        flexDirection: 'column',
        gap: '20px',
      }}>
      <video ref={videoRef} autoPlay playsInline muted />
      <audio ref={audioRef} style={{ display: 'none' }} autoPlay muted />

      <div style={{ display: 'flex', gap: '10px' }}>
        {isConnected ? (
          <>
            <select
              onChange={(e) => avatar.switchAvatar(Number(e.target.value))}>
              {avatar.avatars.map((avatar) => (
                <option key={avatar.id} value={avatar.id}>
                  {avatar.name}
                </option>
              ))}
            </select>
            <Button onClick={() => avatar.say("Hello, I'm a robot!")}>
              Say
            </Button>
            <Button
              onClick={async () => {
                await avatar.stop();
              }}>
              Stop
            </Button>
            <Button
              onClick={() => {
                avatar.disconnect();
                setIsConnected(false);
              }}>
              Disconnect
            </Button>
          </>
        ) : (
          <Button
            onClick={async () => {
              await avatar.connect();
              setIsConnected(true);
            }}>
            Connect
          </Button>
        )}
      </div>
    </div>
  );
}
```
