# Create T3 App — Full-Stack TypeScript Starter with Next.js, tRPC & Prisma

> The best way to start a full-stack, typesafe Next.js application. Scaffolds a project with Next.js, TypeScript, tRPC, Prisma, Tailwind CSS, and NextAuth.js in seconds.

## Install

Save as a script file and run:

# Create T3 App — Full-Stack TypeScript Starter

## Quick Use
```bash
npm create t3-app@latest my-app
cd my-app
npm run dev
```

## Introduction
Create T3 App is the quickest way to scaffold a production-ready, full-stack TypeScript application. It bundles the most popular and well-tested libraries in the Next.js ecosystem into a single interactive CLI that lets you pick exactly the pieces you need.

## What Create T3 App Does
- Scaffolds a Next.js project with full TypeScript configuration out of the box
- Optionally includes tRPC for end-to-end typesafe APIs without code generation
- Integrates Prisma ORM for type-safe database access and migrations
- Adds Tailwind CSS with sensible defaults and a ready-to-use design system
- Configures NextAuth.js for authentication with multiple provider support

## Architecture Overview
Create T3 App generates a Next.js application using the App Router. tRPC routers live alongside your Next.js API routes and share TypeScript types with the frontend automatically. Prisma manages the database schema and generates a typed client. NextAuth.js handles session management through server-side callbacks. The entire stack shares a single TypeScript project, so type errors surface at build time rather than at runtime.

## Self-Hosting & Configuration
- Run `npm create t3-app@latest` and follow the interactive prompts to choose your stack
- Set `DATABASE_URL` in `.env` to point at any Prisma-supported database (PostgreSQL, MySQL, SQLite)
- Configure OAuth providers in `src/server/auth.ts` for NextAuth.js
- Deploy to Vercel, Railway, or any Node.js hosting that supports Next.js
- Use `npx prisma db push` for rapid prototyping or `npx prisma migrate dev` for production migrations

## Key Features
- Interactive CLI that lets you opt in to tRPC, Prisma, Tailwind, and NextAuth individually
- End-to-end type safety from database schema to React components
- Zero boilerplate API layer when using tRPC with automatic type inference
- Follows the T3 Stack philosophy: simplicity, modularity, and full-stack type safety
- Actively maintained with frequent updates tracking the latest Next.js releases

## Comparison with Similar Tools
- **Next.js create-next-app** — provides a bare Next.js scaffold without opinionated library choices; T3 adds a curated full-stack starting point
- **Blitz.js** — offers a Rails-like full-stack framework on top of Next.js; T3 stays closer to vanilla Next.js with opt-in pieces
- **RedwoodJS** — full-stack React framework with its own router and GraphQL layer; T3 uses Next.js routing and tRPC instead
- **SvelteKit** — different UI framework with its own full-stack approach; T3 is Next.js and React-specific

## FAQ
**Q: Do I have to use every part of the T3 stack?**
A: No. The CLI lets you pick and choose which libraries to include. You can start with just Next.js and Tailwind and add tRPC or Prisma later.

**Q: Which databases does it support?**
A: Any database supported by Prisma, including PostgreSQL, MySQL, SQLite, MongoDB, CockroachDB, and SQL Server.

**Q: Can I deploy it outside of Vercel?**
A: Yes. The generated project is a standard Next.js application that can run anywhere Node.js is available, including Docker containers, AWS, and Railway.

**Q: Is it suitable for production applications?**
A: Yes. The T3 stack is used in production by many companies. The scaffold includes TypeScript strict mode, ESLint, and sensible security defaults.
