Create categories for static array to enable automatic suggestions

I have a JavaScript library that needs to export various constants for users who are working with vscode or TypeScript. The goal is to enable auto-complete functionality for specific constant options.

So far, I've attempted to export a Constant in the index.d.ts file using an interface and different option types, but unfortunately, it hasn't been successful. How can I make this work?

index.d.ts

type ColorOption =
  | "blue"
  | "green"
  | "red"
  | "white"
  | "gray";

interface Constant {
  Colors: ColorOption;
  Fonts: ...;
  Icons: ...;
  Spacing: ...;
}

export default Constant

The ideal scenario would be to have autocomplete suggestions like Constants.Colors.red or Constants.Fonts.xlarge.

EDIT:

Adding export type seems to only work when used as a prop, such as <Component type="red" />, whereas enums function correctly when accessed as Constants.Colors.red. Is there a way to make both methods work seamlessly?

Answer №1

To address your query, I suggest following these steps:Instructions:

create a selection of ColorOption:
  - "blue"
  - "green"
  - "red"
  - "white"
  - "gray";

define Constant interface with the following properties:
   Colors: ColorOption;
   Fonts: ...;
   Icons: ...;
   Spacing: ...;

}
