Implementing a Name Interface in Typescript - A Step-by-Step Guide

export declare const TerminalWidgetOptions; unique symbol;
export interface TerminalWidgetOptions {
    endpoint: Endpoint.Options,
    id: string,
    caption: string,
    label: string
    destroyTermOnClose: boolean
}

Upon implementing this interface in a class, I encounter an error: error TS2507: Type 'unique symbol' is not a constructor function type.

It is puzzling to me why TypeScript is unable to recognize the interface.

Can someone please provide an explanation?

Answer №1

Have you attempted to declare the symbol before defining and exporting it?

declare const TerminalWidgetOptions: unique symbol;

export interface TerminalWidgetOptions {
    endpoint: Endpoint.Options;
    id: string;
    caption: string;
    label: string;
    destroyTermOnClose: boolean;
}

I looked at the official documentation.
