how to handle dynamic properties

[balazssoltesz]

Hello,

I try to figure out, how should i handle dynamic properties in an Object/InputType. My main problem is i declared languages in my app's config file, and want to generate ObjectType and InputType based on my used languages in the app.
So i have an array with available languages:

const languages = ["en", "de"] as const;

An I wanna generate types based on this array:

@ObjectType()
class IntlObject {
  @Field()
  [lang: typeof languages[number]]: string;
}

But it doesn't work. Any idea, how can i handle this issue?

You should describe the languages as an enum and then create an object type with lang: Language and value: string (or label, whatever works for you).

So then you can in runtime return proper data, like:

return {
  data: "...",
  intl: {
    lang: Language.EN,
    value: "foo bar",
  },
};

Thanks for your answer!
I'm using typegoose with mongoose-intl plugin, where localizable fields described like

title: {
  en: 'foo',
  de: 'bar',
}

so i have to convert data format to db and back for every localizable field?

Or you can create the IntlObject with normal en and de properties, without using dynamic enum.
