Auth Patterns

Quick Pattern

// Login form
export const login = form(schema, async ({ email, password }) => {
    const event = getRequestEvent();
    await auth.api.signInEmail({
        body: { email, password },
        headers: event.request.headers,
    });
    redirect(303, '/dashboard'); // Outside try/catch
});

// Protected query
export const get_data = guarded_query(() => {
    return { message: 'Protected data' };
});

Core Principles

• Use getRequestEvent() for headers (cookie access)
• Redirect MUST be outside try/catch (throws error)
• Use guarded_query/form/command for protected endpoints
• Email verification required before login
• Commands cannot redirect - use client-side goto()
