Chess.js TypeScript declaration file for easy implementation

Currently, I am delving into learning typescript and have taken up the challenge of crafting a declaration file for the chess.js library. However, it seems that I am struggling to grasp the concept of creating one. Whenever I attempt to import the library using the import statement

import { Chess } from chess.js

An error pops up stating that Module chess.js does not have any exported members.

So far, this is what I have in the index.d.ts file:

declare namespace ChessJSTypes {
    type ChessType = 'p' | 'n' | 'b' | 'r' | 'q' | 'k';

    type ChessColor = 'b' | 'w';
}

// Followed by various interfaces and classes related to chess functionality 
// and concluding with module declaration

Answer №1

If you want to keep your code organized, one approach is to encapsulate the module and contain all its content inside without exporting anything from within:

import * as Checkers from 'checkers.js';

encapsulate module 'checkers.js' {
    class Checkers {
        // ...
    }
}
