Usage

Update file in app.module.ts

`typescript
import { HttpException, HttpStatus, Module } from '@nestjs/common';
import { ValidationError } from 'class-validator-multi-lang';
import { TranslatesModule } from 'nestjs-translates';
import { join } from 'path';
import { AppController } from './app.controller';

@Module({
imports: [
TranslatesModule.forRootDefault({
localePaths: [
join(__dirname, 'assets', 'i18n'),
join(__dirname, 'assets', 'i18n', 'class-validator-messages'),
],
defaultLocale: 'en',
locales: ['en', 'ru'],
validationPipeOptions: {
transform: true,
validationError: {
target: false,
value: false,
},
transformOptions: {
strategy: 'excludeAll',
},
exceptionFactory: (errors: ValidationError[]) =>
new HttpException(errors, HttpStatus.BAD_REQUEST),
},
// disable multi language validation pipe
// usePipe: false
}),
],
controllers: [AppController],
})
export class AppModule {}
`

Create dictionaries ../assets/i18n/ru.json

`json
{
"word": "слово"
}
`

!example

Use translates module with isolated storage for translations in only one feature module

`typescript
import { TranslatesModule } from 'nestjs-translates';
import { join } from 'path';

@Module({
imports: [
SubFeatureModule,
TranslatesModule.forFeature({
localePaths: [join(__dirname, 'assets', 'feature-i18n')],
defaultLocale: 'en',
locales: ['en', 'ru'],
}),
],
})
export class FeatureModule {}
