How to use

First, export an environment variable called CLASS_VALIDATOR_I18N_LANGUAGE specifying the language.
The default language is en-US.

``
export CLASS_VALIDATOR_I18N_LANGUAGE=pt-BR
`

After that you just need to use the decorators imported from 'class-validator-i18n' instead of the original 'class-validator'.
All the validators that are not translated yet will still working with original messages in english.

`
import { IsArray, IsString } from 'class-validator-i18n';

export class Testing {
@IsArray()
array: string[];

@IsString({ description: 'Description os testing' })
description: string;
}
``

For NestJS projects, define variable before starts the project, for example, inside the package.json, on start:dev script or wherever.

NestJS doesn't guarantee that .env file will loads before decorators. This will make your errors be in default language, that is en-US.
