VoltAgent Vercel UI SDK Integration

VoltAgent integration with the Vercel UI SDK for building agentic applications.

🚀 Quick Start

``bash
npm install @voltagent/vercel-ui
`

`typescript
import { convertToUIMessages } from "@voltagent/vercel-ui";
import { VercelAIProvider } from "@voltagent/vercel-ai";
import { Agent } from "@voltagent/core";

const agent = new Agent({
id: "assistant",
name: "Assistant",
purpose: "A helpful assistant that can answer questions and help with tasks.",
instructions: "You are a helpful assistant that can answer questions and help with tasks.",
model: "gpt-4.1-mini",
llm: new VercelAIProvider(),
hooks: {
onEnd: async (result) => {
await chatStore.save({
conversationId: result.conversationId,
messages: convertToUIMessages(result.operationContext),
});
},
},
});

const result = await agent.generateText("Hello, how are you?");

// You can now fetch the messages from your custom chat store and return to the UI to provide a
// history of the conversation.

app.get("/api/chats/:id", async ({ req }) => {
const conversation = await chatStore.read(req.param("id"));
return Response.json(conversation.messages);
});
`
