In the previous post, we have seen how to save User Passwords.

Let’s check use of enumerations or enums.

Hypi facilitates declaring a list of items in enumerations format. You may declare your own enum in the schema.

enum Color {
  YELLOW
  BLUE
  GREEN
}

There are in-built enums that you can use in your application. Check Core app.

Enums can only have a finite set of values. Values apart from the listed ones are not allowed.

Use enum as a field type in any data type.

type ChooseColor {
    current: Color
}

Insert or update enum value using upsert.

mutation {
  upsert(values: { ChooseColor: [{ current: GREEN }] }) {
    id
  }
}

#result

{
  "data": {
    "upsert": [
      {
        "id": "01gespecz4azc8nwn5vs5fs9ct"
      }
    ]
  }
}

Retrieve enum value using get function.

{
  get(type: ChooseColor, id: "01gespecz4azc8nwn5vs5fs9ct") {
    ... on ChooseColor {
      current
    }
  }
}

#result

{
  "data": {
    "get": {
      "current": "GREEN"
    }
  }
}
