SvelteKit Data Flow

Quick Start

Which file? Server-only (DB/secrets): +page.server.ts |
Universal (runs both): +page.ts | API: +server.ts

Load decision: Need server resources? → server load | Need client
APIs? → universal load

Form actions: Always +page.server.ts. Return fail() for
errors, throw redirect() to navigate, throw error() for failures.

Example

// +page.server.ts
import { fail, redirect } from '@sveltejs/kit';
