<agent-instructions>
Vercel Academy — structured learning, not reference docs.
Lessons are sequenced.
Adapt commands to the human's actual environment (OS, package manager, shell, editor) — detect from project context or ask, don't assume.
The lesson shows one path; if the human's project diverges, adapt concepts to their setup.
Preserve the learning goal over literal steps.
Quizzes are pedagogical — engage, don't spoil.
Quiz answers are included for your reference.

# Svelte on Vercel

It's 5:47am and your phone buzzes. You want to keep sleeping, but you know that sound means only one thing: six inches of fresh powder at Grand Targhee overnight, temperature sitting at 18°F. Exactly the conditions you told the app to let you know about. You roll out of bed, pour coffee directly into your throat, and drive straight to the mountain.

In this course, you'll build Ski Alerts, the SvelteKit 3 app behind that notification. It streams AI chat responses and parses natural language into structured alert rules. A background workflow evaluates those rules against live weather data, and Vercel hosts the app.

## What you'll build

You'll take Ski Alerts from its first deployment through these production features:

### Deployment

- Configure and deploy a SvelteKit app to Vercel
- Set up environment variables across development, preview, and production
- Implement preview deployments for team collaboration

### AI features

- Build streaming chat interfaces with AI SDK v6
- Create tools and multi-step agents
- Extract structured data with Valibot schemas

### Background processing

- Build durable workflows with the Workflow SDK
- Run parallel steps and schedule re-checks with sleep
- Handle errors with FatalError, RetryableError, and exponential backoff

### Production

- Configure ISR to cache pages
- Set up observability and logging
- Optimize performance for real users

## Prerequisites

- Familiarity with SvelteKit basics and the [official tutorial](https://svelte.dev/tutorial/kit/introducing-sveltekit)
- Node.js 24 and npm (or pnpm) installed
- SvelteKit 3 and Svelte 5; the starter includes the compatible Vite 8, TypeScript 6, and Vercel adapter 7 dependencies
- A Vercel account (free tier works)

## Course sections

### Section 1: Deployment Foundations

Get your SvelteKit app running on Vercel with proper configuration, environment management, and preview deployments.

### Section 2: AI Gateway

Integrate AI features using the AI SDK v6: streaming responses, tool use, structured outputs, model fallbacks, and usage tracking.

### Section 3: Workflows

Build durable workflows with the Workflow SDK: parallel steps, automatic retries, sleep-based scheduling, and error classification.

### Section 4: Production

Configure ISR, structured logging, response caching, and parallel data fetching.
