The Pipecat JavaScript SDK provides a lightweight client implementation that handles:
  • Device and media stream management
  • Connecting to Pipecat bots
  • Messaging with Pipecat bots and handling responses using the RTVI standard
  • Managing session state and errors

​
Installation

Install the SDK and a transport implementation (e.g. Daily for WebRTC): 
npm install @pipecat-ai/client-js
npm install @pipecat-ai/[daily-transport, small-webrtc-transport, etc.]

​
Example

Here’s a simple example using Daily as the transport layer: 
import { PipecatClient } from "@pipecat-ai/client-js";
import { DailyTransport } from "@pipecat-ai/daily-transport";

// Handle incoming audio from the bot
function handleBotAudio(track, participant) {
  if (participant.local || track.kind !== "audio") return;

  const audioElement = document.createElement("audio");
  audioElement.srcObject = new MediaStream([track]);
  document.body.appendChild(audioElement);
  audioElement.play();
}

// Create and configure the client
const pcClient = new PipecatClient({
  transport: new DailyTransport(),
  enableMic: true,
  callbacks: {
    onTrackStarted: handleBotAudio,
  },
});

// Connect to your bot
pcClient.connect({
  url: "https://your-daily-room-url",
  token: "your-daily-token",
});
