@dudousxd/nestjs-codegen-zod

Zod validation adapter for @dudousxd/nestjs-codegen.

nestjs-codegen translates your @Body()/@Query() DTOs and defineContract schemas into one neutral schema IR (SchemaNode), then renders that IR with a validation adapter. This package is the zod adapter: it renders the IR into zod source in the generated forms.ts.

zod is the default validation adapter — reach for this package when you want to pin the adapter explicitly, or when a future core release no longer bundles it by default.

Install

pnpm add -D @dudousxd/nestjs-codegen-zod

zod itself is the runtime dependency your generated forms.ts imports from (import { z } from 'zod'), so install it in your app too:

pnpm add zod

Setup

zod is used by default. To pin the adapter explicitly, pass zodAdapter to the codegen config:

import { defineConfig } from '@dudousxd/nestjs-codegen';
import { zodAdapter } from '@dudousxd/nestjs-codegen-zod';

export default defineConfig({
  validation: zodAdapter,
});

Given a DTO like:

class CreateUserDto {
  @IsEmail() email!: string;
  @MinLength(8) password!: string;
}

the adapter renders forms.ts in zod's idiom:

import { z } from 'zod';

export const CreateBodySchema = z.object({
  email: z.string().email(),
  password: z.string().min(8),
});
export type CreateBody = z.infer<typeof CreateBodySchema>;

How it fits

The codegen builds one neutral schema IR from your DTOs and contracts. A validation adapter renders that IR into a concrete library's source:

• zod — this package, the default (validation: 'zod')
• valibot — @dudousxd/nestjs-codegen-valibot (validation: valibotAdapter)
• arktype — @dudousxd/nestjs-codegen-arktype (validation: arktypeAdapter)

Pick exactly one — it decides which library your generated forms.ts imports and validates with.
