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

> An interactive CLI that scaffolds a production-ready full-stack TypeScript application with a curated stack of Next.js, tRPC, Tailwind CSS, Prisma, and NextAuth.js.

## Install

Save in your project root:

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

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

## Introduction
Create T3 App is an interactive CLI that generates a full-stack TypeScript project following the T3 Stack philosophy: simplicity, modularity, and end-to-end type safety. It lets developers pick from a curated set of libraries rather than starting from scratch or wading through boilerplate.

## What Create T3 App Does
- Scaffolds a Next.js project with TypeScript configured out of the box
- Optionally adds tRPC for end-to-end typesafe APIs without code generation
- Integrates Prisma ORM for database access with type-safe queries
- Configures NextAuth.js for authentication with multiple providers
- Sets up Tailwind CSS with sensible defaults and dark mode support

## Architecture Overview
The CLI prompts the user for which packages to include, then assembles a project from composable template partials. Each optional library (tRPC, Prisma, NextAuth, Tailwind) has its own partial that merges cleanly with the base Next.js template. The result is a single Next.js app where the API layer uses tRPC routers, the database layer uses Prisma, and authentication flows through NextAuth session providers.

## Self-Hosting & Configuration
- Run the CLI with npx, npm create, yarn create, or pnpm create
- Select packages interactively or pass flags like --tailwind --trpc --prisma
- Configure environment variables in the generated .env file for database URL and auth secrets
- Deploy to Vercel, Railway, or any Node.js host with zero additional config
- The generated project includes a ready-to-use Docker configuration for self-hosting

## Key Features
- Fully interactive scaffolding with sensible defaults at every step
- End-to-end type safety from database schema to frontend components
- Modular architecture where every optional package can be excluded
- Community-maintained documentation with deployment guides for major platforms
- Regular updates tracking the latest stable versions of all included libraries

## Comparison with Similar Tools
- **create-next-app** — official Next.js starter; minimal, no opinionated stack choices
- **Blitz.js** — full-stack React framework with built-in auth and RPC; heavier abstraction
- **RedwoodJS** — full-stack JS framework with GraphQL API layer; different API paradigm
- **SvelteKit** — full-stack Svelte framework; different frontend ecosystem entirely
- **Wasp** — DSL-based full-stack framework; generates React + Node code from a config file

## FAQ
**Q: Do I have to use all the packages in the T3 Stack?**
A: No. The CLI lets you pick only what you need. A valid T3 app can be just Next.js with Tailwind.

**Q: What databases does the Prisma integration support?**
A: Prisma supports PostgreSQL, MySQL, SQLite, SQL Server, MongoDB, and CockroachDB. Configure the provider in schema.prisma.

**Q: Can I use the App Router instead of Pages Router?**
A: Yes. Recent versions of Create T3 App default to the Next.js App Router with full support for server components.

**Q: Is this suitable for production applications?**
A: Yes. The generated code follows production patterns including environment variable validation, strict TypeScript config, and proper error handling.
