ZOD_SCHEMA_KEY

const ZOD_SCHEMA_KEY: "_zodSchema"

Defined in: packages/pipeline-zod/src/zod-validation.behavior.ts:63

Conventional property key used to attach a Zod schema to a command, query, or event class.

Classes built with createCommand(), createQuery(), or createZodRequest() automatically receive this property, so ZodValidationBehavior can introspect and validate without extra wiring.

For manually-written event classes you can attach the schema yourself:

Example

import { ZOD_SCHEMA_KEY } from '@cqrs-ddd/pipeline-zod';
import { z } from 'zod';

const userCreatedSchema = z.object({
  userId: z.uuid(),
  username: z.string().min(1),
  email: z.email(),
});

export class UserCreatedEvent {
  static readonly [ZOD_SCHEMA_KEY] = userCreatedSchema;

  constructor(
    public readonly userId: string,
    public readonly username: string,
    public readonly email: string,
  ) {}
}
