tavus-engineering Tavus CVI React UI Components
Pre-built React components for embedding CVI conversations.
Quick Setup (Vite)
npm create vite@latest my-app -- --template react-ts
cd my-app
npm install
npx @tavus/cvi-ui@latest init
npx @tavus/cvi-ui@latest add conversation
Creates:
src/components/cvi/components/
├── cvi-provider.tsx
└── conversation.tsx
Create cvi-components.json in project root:
{
"tsx": true
}
Environment Variables
.env in project root:
VITE_TAVUS_API_KEY=your_api_key
VITE_REPLICA_ID=rfe12d8b9597
VITE_PERSONA_ID=pdced222244b
Basic Implementation
import { useState } from "react";
import { CVIProvider } from "./components/cvi/components/cvi-provider";
import { Conversation } from "./components/cvi/components/conversation";
export default function App() {
const [url, setUrl] = useState<string | null>(null);
const startConversation = async () => {
const res = await fetch("https://tavusapi.com/v2/conversations", {
method: "POST",
headers: {
"Content-Type": "application/json",
"x-api-key": import.meta.env.VITE_TAVUS_API_KEY,
},
body: JSON.stringify({
replica_id: import.meta.env.VITE_REPLICA_ID,
persona_id: import.meta.env.VITE_PERSONA_ID,
}),
});
const data = await res.json();
setUrl(data.conversation_url);
};
return (
<CVIProvider>
{!url ? (
<button
) : (
<Conversation
conversationUrl={url}
=> setUrl(null)}
/>
)}
</CVIProvider>
);
}
Component: CVIProvider
Wraps your app, provides CVI context:
import { CVIProvider } from "./components/cvi/components/cvi-provider";
function App() {
return (
<CVIProvider>
{/* Your app */}
</CVIProvider>
);
}
Component: Conversation
The main video conversation UI:
<Conversation
conversationUrl={url}
=> setUrl(null)}
/>
Required: Parent container must have defined dimensions.
<div style={{ width: "100%", height: "600px" }}>
<Conversation conversationUrl={url} />
</div>
Hooks
useAppMessage
Listen for CVI events:
import { useAppMessage } from "./components/cvi/hooks/use-app-message";
function MyComponent() {
useAppMessage((event) => {
if (event.event_type === "conversation.utterance") {
console.log("Said:", event.properties.content);
}
});
return <div>...</div>;
}
useSendAppMessage
Send interactions to CVI:
import { useSendAppMessage } from "./components/cvi/hooks/use-send-app-message";
function Controls() {
const send = useSendAppMessage();
const interrupt = () => {
send({
message_type: "conversation",
event_type: "conversation.interrupt",
conversation_id: "xxx"
});
};
return <button
}
Alternative: iframe Embedding
For non-React or quick integration:
<iframe
src="CONVERSATION_URL"
allow="camera; microphone; display-capture"
style="width: 100%; height: 600px; border: none;"
></iframe>
Server-Side API Calls (Recommended)
Keep API key on server:
// pages/api/conversation.ts (Next.js)
export default async function handler(req, res) {
const response = await fetch("https://tavusapi.com/v2/conversations", {
method: "POST",
headers: {
"Content-Type": "application/json",
"x-api-key": process.env.TAVUS_API_KEY,
},
body: JSON.stringify({
replica_id: process.env.REPLICA_ID,
persona_id: process.env.PERSONA_ID,
}),
});
const data = await response.json();
res.json({ conversation_url: data.conversation_url });
}
Client calls your API:
const res = await fetch("/api/conversation", { method: "POST" });
const { conversation_url } = await res.json();
Styling the Conversation
Wrap in styled container:
<div style={{
width: "100%",
maxWidth: "900px",
margin: "0 auto",
borderRadius: "12px",
overflow: "hidden",
boxShadow: "0 4px 20px rgba(0,0,0,0.15)",
}}>
<Conversation conversationUrl={url} />
</div>
HairCheck Component
Pre-call device check:
npx @tavus/cvi-ui@latest add haircheck
import { HairCheck } from "./components/cvi/components/haircheck";
<HairCheck => setShowConversation(true)} />
