Svelte 5 + AI SDK Integration Guide

Step 1: Install Required Components

Let's install message and prompt input components.

pnpm dlx shadcn-svelte@latest add https://svelte-ai-elements.vercel.app/r/message.json
pnpm dlx shadcn-svelte@latest add https://svelte-ai-elements.vercel.app/r/prompt-input.json

Step 2: Create Server Endpoint

Create the API endpoint in

src/routes/api/chat/+server.ts

src/routes/api/chat/+server.ts

This server endpoint handles incoming chat messages and streams AI responses back to the frontend using the AI SDK.

Step 3: Create Frontend Chat Interface

Build the chat interface inside

src/routes/+page.svelte
using AI SDK's Svelte:

src/routes/+page.svelte

The

Chat
class from AI SDK automatically handles message state, streaming, and form submission, making it incredibly easy to build chat interfaces.

For more details, refer to the official Vercel AI SDK Svelte documentation.
