DRZL

Zero‑friction codegen for Drizzle ORM. Analyze your schema. Generate validation, services, and routers — fast.

What’s Inside

• Analyzer: turns Drizzle schemas into a normalized analysis model
• Generators: Zod, Valibot, ArkType validation; typed CRUD services; router templates (oRPC)
• Batteries: formatting, naming, reusable/shared schemas, relation support
• Monorepo: pnpm workspace, lockstep releases with Changesets

Install & Use

• Install the CLI and init a config

pnpm add @drzl/cli -D
pnpm drzl init

• Generate code

pnpm drzl generate -c drzl.config.ts

Minimal config

// drzl.config.ts
import { defineConfig } from '@drzl/cli/config';

export default defineConfig({
  schema: 'src/db/schemas/index.ts',
  outDir: 'src/api',
  generators: [
    { kind: 'zod', path: 'src/validators/zod' },
    { kind: 'service', path: 'src/services', dataAccess: 'drizzle' },
    { kind: 'orpc', template: '@drzl/template-orpc-service' },
  ],
});
