next-config-gen

Next Config Generator

next.config.js has a million options. This tool reads your project and generates a config with sensible defaults and the features you actually need.

One command. Zero config. Just works.

Quick Start

npx ai-next-config

What It Does

• Analyzes your Next.js project
• Generates optimized next.config.mjs
• Includes image domains, rewrites, and headers
• Sets up best practice defaults

Usage Examples

# Generate from current project
npx ai-next-config

# Output as CommonJS
npx ai-next-config -o next.config.js

Best Practices

• Enable strict mode - catch issues early
• Configure image domains - external images need allowlisting
• Set security headers - HTTPS, CSP, etc.
• Use rewrites carefully - they can affect caching

When to Use This

• Starting a new Next.js project
• Upgrading to latest Next.js version
• Adding features like image optimization
• Cleaning up messy config
