$ npm i class-validator translated-class-validator

This repository only wraps class-validator with the default message of rules of class-validator in each language. Therefore, you can import the language you want to read and use it in exactly the same way as class-validator. Therefore, please refer to class-validator for usage.

However, only the import statement should load this package as shown below. You can also import by language, so specify lang in translated-class-validator/lang as the language you want to translate.

import {
  validate,
  validateOrReject,
  Contains,
  IsInt,
  Length,
  IsEmail,
  IsFQDN,
  IsDate,
  Min,
  Max,
} from 'translated-class-validator/ja';

If you are already using class-validator, you can apply the translated default error messages without any effect at all by replacing translated-class-validator with sed or similar.

- import {IsDefined} from 'class-validator';
+ import {IsDefined} from 'translated-class-validator/ja';

Add your country's language if you feel like it. :)

I want to your contribute for language. The way to contribute is very simple.

Please add the translated files for each rule to src/ruleMessages in this repository and PR them.

The translation will be completed if you define the default message for the required rule, stating the following.

import type { TranslationObject } from "../types/translation";

export const messages: TranslationObject = {
  IsDefined: '$property is required.',
  //... It can be only some of the rules or all of the rules.
};
