Auth and Guards

Implement auth checks in middleware and redirect unauthenticated users.

import { createRouter } from '@vielzeug/routeit';

const requireAuth = async (ctx, next) => {
  if (!session.currentUser) {
    await ctx.navigate({ name: 'login' }, { replace: true });
    return;
  }

  ctx.locals.user = session.currentUser;
  await next();
};

const router = createRouter({
  routes: {
    login: {
      path: '/login',
      handler: () => renderLogin(),
    },
    dashboard: {
      path: '/dashboard',
      middleware: [requireAuth],
      handler: (ctx) => renderDashboard(ctx.locals.user),
    },
    notFound: {
      path: '*',
      handler: () => renderNotFound(),
    },
  },
});

This keeps access rules near the route while preserving a clear handler pipeline.
