Base App Setup

This is a sequential cookbook that takes you from zero to a production-ready Next.js stack with all the modern fixings: Shadcn UI for components, Neon Postgres with Drizzle ORM for your database, and Vercel's AI SDK for chat interfaces. The recipes are meant to be run in order, and they cover the boring but critical stuff like environment validation with better-env and editor config that you'd otherwise spend hours cobbling together from Stack Overflow. It's opinionated in good ways, skipping ESLint complexity in favor of just Prettier and TypeScript, and using Bun as the runtime. If you're spinning up a new AI-powered app and don't want to make a dozen architectural decisions before writing your first feature, this gets you there fast.
