TypeScript Question

How do I import other TypeScript files?

When using the TypeScript plugin for vs.net, how do I make one TypeScript file import modules declared in other TypeScript files?

file 1:

module moo
{
export class foo .....
}


file 2:

//what goes here?

class bar extends moo.foo
{
}

Answer

You need to reference the file on the top of the current file.

You can do this like this:

/// <reference path="../typings/jquery.d.ts"/>
/// <reference path="components/someclass.ts"/>

class Foo { }

etc.

These paths are relative to the current file.

Your example:

/// <reference path="moo.ts"/>

class bar extends moo.foo
{
}

UPDATE: From TypeScript version 1.5 you can use tsconfig.json: http://www.typescriptlang.org/docs/handbook/tsconfig-json.html

It completely eliminates the need of the comment style referencing.
