How to use special character (-) in appsync enum?

Question

I would like to represent locale information using appsync Type enum. However, there are some special inside locale information. e.g. the - in en-US, en-UK.

If it is possible, I want to retain the format of the locale string.

Answer 1

The GraphQL specification does not allow - in names. So the answer is simply that it is not possible.

What you could do is create an object type that wraps the enum and the locale string:

enum LocaleIdentifier {
  EN_US
  EN_UK
  # ...
}

type Locale {
  id: LocaleIdentifier
  str: String
}

This would allow you to use the string in the frontend every time you get a Locale but reference the locale with an enum type. I am not sure if there is a lot of value in that instead of simply using the string directly.
