Code That Speaks for Itself

Real-world patterns used by 50,000+ developers in production every day.

auth/middleware.ts

import { withAuth, requireRole } from '@devkit/auth';

export const protectedRoute = withAuth({
strategies: ['jwt', 'session'],
onUnauthorized: (ctx) => ctx.redirect('/login'),
}).use(requireRole('admin'));

// Apply to any route handler
export { protectedRoute as middleware };

cache/strategy.ts

import { CacheStrategy, defineCache } from '@devkit/cache';

const cache = defineCache({
  driver: 'redis',
