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';
