Next.js 14 + Auth0 v4 Authentication Boilerplate

Setting up authentication in Next.js is one of the most time-consuming parts of starting a new project. This boilerplate eliminates that entirely. The Next.js 14 Auth0 v4 Authentication Boilerplate gives you a fully working auth flow out of the box — login, logout, session management, and protected routes — all configured with the latest Auth0 v4 SDK and Next.js 14 App Router conventions. Auth0 v4 introduced breaking changes from previous versions, and integrating it correctly with the Next.js App Router requires specific setup that isn't always well-documented. This boilerplate handles all of that for you. Built with Next.js 14, Tailwind CSS, shadcn/ui, and Auth0 v4, the project follows production patterns: middleware-based route protection, server-side session access, and clean separation between public and authenticated pages. Who is this for? Developers who need a Next.js authentication starter, teams that use Auth0 and want to skip the integration work, or anyone building a SaaS or web app that needs secure login from day one. If you've been searching for a Next.js Auth0 boilerplate, a Next.js 14 authentication template, or an App Router auth starter — this is it. What's included: Auth0 v4 integration, protected routes with middleware, login/logout flow, session handling, TypeScript, Tailwind CSS, shadcn/ui, and full source code. Skip the docs. Skip the errors. Start building what matters.
