Resolvers

The resolvers option is used to configure resolvers. The resolvers takes in array of resolvers so you can add in any number of resolvers you like. nestjs-i18n comes with a set of built-in resolvers.

Name	Default value
`QueryResolver`	`['lang']`
`HeaderResolver`	`[]`
`AcceptLanguageResolver`	`{matchType: 'strict-loose'}`
`CookieResolver`	`lang`
`GraphQLWebsocketResolver`	`N/A`
`GrpcMetadataResolver`	`['lang']`

src/app.module.ts
       I18nModule.forRoot({
          fallbackLanguage: 'en',
          loaderOptions: {
            path: path.join(__dirname, '/i18n/'),
          },
          resolvers: [
            new QueryResolver(['lang', 'l']),
            new HeaderResolver(['x-custom-lang']),
            new CookieResolver(),
            AcceptLanguageResolver,
          ],
        }),

tip

If you need to implement a custom resolver, your resolver needs to extend src/interfaces/i18n-language-resolver.interface.ts interface. Also you can check the src/resolvers to see how the default resolvers are implemented.
