Error while trying to share an interface across different files in Typescript

I'm making a card game in Typescript. So far, I have a main app.ts file, and these two files.

Card.ts

module Cardgame
{
    export interface Card
    {
        name: string;
    }
}

Deck.ts

/// <reference path='Card.ts' />

module Cardgame
{
    export interface Deck
    {
        name: string;
        content: Card[];
    }
}

Compiling the app, or compiling Deck.ts directly, yields the following error:

C:\Dropbox\Cardgame\app\cardgame\Deck.ts(8,12): error TS2095: Could not find symbol 'Card'.

However, placing the Card interface in the same file as Deck works fine:

module Cardgame
{
    export interface Card
    {
        name: string;
    }

    export interface Deck
    {
        name: string;
        content: Card[];
    }
}

What can I do to keep them in separate files?

node.js
typescript

Answer 1

Probably an old version of the compiler or some other error. It compiles fine as shown below : enter image description here

PS: in node you shouldn't use internal modules. see https://www.youtube.com/watch?v=KDrWLMUY0R0&hd=1

Answer 2

You should put your references in the app.ts file.

/// <reference path='Card.ts' />
/// <reference path='Deck.ts' />

class App{

}

Then run tsc against only app.ts

tsc --out app.js app.ts
