Better Auth Demo for SvelteKit

This project demonstrates a robust authentication setup in SvelteKit using the better-auth library. It covers login, registration, session management, and secure navigation patterns for modern SvelteKit apps.

Features

• Email/password authentication
• Session management with cookies
• Reactive auth context using Svelte 5 runes
• Secure navigation and invalidation
• Example dashboard and protected routes
• Clean, modern UI components

Getting Started

Prerequisites

• Node.js (v18+ recommended)
• pnpm (recommended)

Database setup

This demo uses a simple SQL database for user storage. You can use any SQL database (PostgreSQL, MySQL, SQLite, etc.) that you prefer.

• The schema is in db/schema.sql. Use your preferred SQL database and apply the schema.
• Configure your database connection in environment variables as needed.

Build for production

pnpm run build
