tsconfig-gen

TSConfig Generator

Get the right tsconfig for your project without reading docs. Tell it what you're building and get a properly configured TypeScript setup.

One command. Zero config. Just works.

Quick Start

npx ai-tsconfig "next.js app with strict mode"

What It Does

• Generates tsconfig.json tailored to your project type
• Sets correct module resolution and target for your runtime
• Configures path aliases and includes/excludes
• Enables appropriate strict mode options
• Handles library, app, and monorepo configurations

Usage Examples

# Next.js project
npx ai-tsconfig "next.js 14 app router"

# Node.js library
npx ai-tsconfig "node library targeting esm and cjs"

# React app with Vite
npx ai-tsconfig "react spa with vite, strict mode"

Best Practices

• Match your target - Node 18+ can use esnext, older runtimes need downleveling
• Enable strict gradually - Start with strict:false if migrating from JS
• Use project references - For monorepos, generate configs per package
• Keep paths simple - Alias @/ to src/ and call it a day

When to Use This

• Starting any TypeScript project
• Upgrading an existing tsconfig to modern settings
• Understanding what each compiler option actually does
• Setting up build configurations for publishing packages
