$data references for validation#
Version 2.4 allows you to enable the AJV $data option so that you can use the verified data values as validators for other values.

export class AuthController {
@Post('/signup')
@ValidateBody({
type: 'object',

password: { type: 'string' },
// "password" and "confirmPassword" should be identical.
confirmPassword: {
const: {
$data: '1/password',
type: 'string',
required: [ 'username', 'password', 'confirmPassword' ],
additionalProperties: false
