Archetype

TL;DR: Define your data model once. Get database, validation, API, and hooks generated automatically.

// You write this
const User = defineEntity('User', {
  fields: {
    email: text().required().email(),
    name: text().required(),
  },
  protected: 'write',
})

// You get this

npm install archetype-engine
npx archetype init --yes
npx archetype generate
npx drizzle-kit push && npm run dev

Why Use This?

Without Archetype:

1. Write Drizzle schema
2. Write Zod schema (duplicate field definitions)
3. Write tRPC router (duplicate again)
4. Write React hooks
5. Keep all 4 in sync manually

With Archetype:

1. Define entity once
2. Run npx archetype generate
3. Done
