Switching your web app to use the ElevenLabs WebSocket API for real-time conversational AI interactions can vary in complexity depending on your current implementation. Here are some key considerations to help you estimate the effort required:

1. Understanding WebSocket Integration

• The WebSocket API allows for real-time, interactive voice conversations by sending audio input and receiving audio responses in real-time. This is different from REST APIs, which are request-response based.
• You will need to establish a WebSocket connection using the endpoint:
  wss://api.elevenlabs.io/v1/convai/conversation?agent_id={agent_id}.

2. Changes to Your Backend

• If your current app uses REST APIs, you’ll need to modify your backend to handle WebSocket connections. This includes:
  • Fetching a signed WebSocket URL for private agents (if applicable).
  • Managing WebSocket events like onopen, onmessage, onerror, and onclose.
• Example of fetching a signed URL:

  curl -X GET "https://api.elevenlabs.io/v1/convai/conversation/get_signed_url?agent_id=<your-agent-id>" \
       -H "xi-api-key: <your-api-key>"
  

3. Client-Side Adjustments

• Your client-side code will need to handle real-time audio streaming:
  • Capture audio from the user’s microphone.
  • Send audio chunks to the WebSocket server in the required format (PCM 16-bit mono, base64-encoded, 16,000 Hz sample rate).
  • Process audio responses from the server.
• Example of sending audio chunks:

  {
    "user_audio_chunk": "<base64-encoded-audio-data>"
  }
  

4. UI Updates

• Update your UI to reflect real-time states, such as connection status, speaking/listening indicators, and error handling.

5. Testing and Debugging

• Real-time systems require thorough testing to ensure low latency and smooth interactions. You may need to implement:
  • Adaptive buffering for audio.
  • Reconnection logic for WebSocket failures.
  • Ping-pong messages to monitor latency.

6. Effort Estimation

• If your app already has a modular structure, transitioning to WebSocket might not take long. However, if your app is tightly coupled with REST APIs, it could require significant refactoring.
• For a small-to-medium app, the transition could take a few days to a couple of weeks, depending on your familiarity with WebSocket protocols and audio processing.

If you need detailed guidance, you can refer to the WebSocket API documentation for implementation specifics.

Currently I am using a Next js project with React, so does I just have to change the api request or It's more complexe ?

Switching from the Conversational AI Agent API to a WebSocket-based implementation in your Next.js and React project will require more than just changing the API request. Here's an overview of what you might need to adjust:

1. WebSocket Connection Setup

• You will need to establish a persistent WebSocket connection to the ElevenLabs WebSocket endpoint. For private agents, you must first generate a signed URL using the REST API and then use it to initiate the WebSocket connection.
• For public agents, you can directly use the agent_id in the WebSocket URL without generating a signed URL.

Example WebSocket URL for public agents:

const url = `wss://api.elevenlabs.io/v1/convai/conversation?agent_id=<your-agent-id>`;

For private agents, generate the signed URL as shown:

const response = await fetch(
  "https://api.elevenlabs.io/v1/convai/conversation/get_signed_url?agent_id=<your-agent-id>",
  {
    method: "GET",
    headers: { "xi-api-key": process.env.ELEVENLABS_API_KEY },
  }
);
const { signed_url } = await response.json();

2. Client-Side WebSocket Integration

• Replace your existing API request logic with WebSocket event handling. This includes managing the connection lifecycle (onopen, onmessage, onerror, onclose) and sending/receiving messages.

Example WebSocket event handling:

const websocket = new WebSocket(signed_url);

websocket.onopen = () => {
  console.log("WebSocket connection established");
};

websocket.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log("Received message:", data);
};

websocket.onerror = (error) => {
  console.error("WebSocket error:", error);
};

websocket.onclose = () => {
  console.log("WebSocket connection closed");
};

3. Audio Streaming

• If your app involves audio input/output, you’ll need to handle audio streaming through the WebSocket. This includes encoding audio data into the required format (e.g., PCM 16-bit mono, base64-encoded) and sending it in chunks.

Example format for sending audio chunks:

websocket.send(
  JSON.stringify({
    user_audio_chunk: "<base64-encoded-audio-data>",
  })
);

4. React Integration

• If you’re using React, you can manage the WebSocket connection using hooks like useEffect for lifecycle management and useState for tracking connection status or received messages.

Example:

import { useEffect, useState } from "react";

const useWebSocket = (url) => {
  const [messages, setMessages] = useState([]);
  const [status, setStatus] = useState("disconnected");

  useEffect(() => {
    const websocket = new WebSocket(url);

    websocket.onopen = () => setStatus("connected");
    websocket.onmessage = (event) =>
      setMessages((prev) => [...prev, JSON.parse(event.data)]);
    websocket.onclose = () => setStatus("disconnected");

    return () => websocket.close();
  }, [url]);

  return { messages, status };
};

5. Error Handling and Reconnection Logic

• Implement robust error handling and reconnection logic to ensure a smooth user experience, especially for real-time applications.

Example reconnection logic:

const reconnect = () => {
  setTimeout(() => {
    // Reinitialize WebSocket connection
  }, 5000); // Exponential backoff can be applied here
};

6. Testing and Debugging

• Test the WebSocket implementation thoroughly to ensure it handles edge cases like network interruptions, large audio chunks, and latency.

Complexity

The complexity of the migration depends on how tightly coupled your current API logic is with the rest of your app. If your app is modular and the API logic is isolated, the transition should be more straightforward. However, if the API logic is deeply integrated, you may need to refactor multiple components

Why is better to use WebSocket than regular api request ?
