A modern React template powered by Next.js 14 (App Router), TypeScript in strict mode, Tailwind CSS, and shadcn/ui components. Server Components, streaming, and partial prerendering deliver lightning-fast initial loads while keeping the bundle lean on the client. All data fetching uses React Server Components and React Query where client state is truly needed. Authentication is pre-wired with NextAuth.js supporting credentials, Google, GitHub, and magic links. Database access is via Prisma (PostgreSQL by default, easily swapped). Deployment guides are provided for Vercel, AWS Amplify, Railway, Fly.io, and self-hosted Docker. End-to-end tests run with Playwright and unit tests with Vitest. The template includes a marketing site, dashboard, user settings, team management, billing with Stripe Checkout and the Customer Portal, an admin panel, blog, documentation site with MDX, and a REST plus GraphQL API layer. Every page is WCAG 2.1 AA compliant and ships with proper OG tags and JSON-LD structured data.
