MERN Starter Kit

Stop wiring up authentication from scratch on every project.This TypeScript MERN starter kid gives you a fully working full-stack foundation - MongoDB, Express, React, and Node, so you can repo and start building your actual product on day one.What's included: A production-structured Express + Node backend with MongoDB via Mongoose, bcrypt password hashing, JWT authentication, and a global error handler that covers Mongoose validation errors, duplicate keys, and token failures out of the box. A React + Vite frontend with a typed Axios instance that automatically attaches your auth token to every request and redirects to login on a 401. Auth state lives in a global React context so any component can access the current user without prop drilling. Every file is written in strict TypeScript—shared interfaces, typed form state, typed middleware, typed Mongoose models - so your IDE catches mistakes before they hit the browser. You get: JWT register / login / protected route flow, ready to extend PrivateRoute component - wrap any page to require authentication AuthContext with useAuth() hook for global user state Axios interceptor handling token injection and auto-logout Mongoose User model with pre-save password hashing Global error handler middleware Clean folder structure following real-world conventions .env.example files for both server and client README with quick start, API, reference, and deployment guide Works with: NodeJS 18+ MongoDB Atlas (free tier is plenty to get started) Render / Railway / Fly.io for the backend Vercel or Netlify for the frontend Who is this for:Developers who know the stack and don't want to spend the first two days of every project re-solving the same auth boilerplate. Clone it, fill in your .env, and build the thing you actually came to build.
