TypeScript definition file : Exporting an instantiated class

Question

There is a specific typescript definition that I cannot currently get working:

mapping.ts
class Mapping {
//
}
var mapping = new Mapping();
export = mapping;

Which enables the use:

import _mapping = require('mapping');
_mapping.doSomething();

However I cannot quite get to the solution of how my mapping.d.ts should be structured to show this and cannot get it to compile.

mapping.d.ts
export var mapping: Mapping;

This fails since the usage would now be:

 _mapping.mapping.doSomething();

Any suggestions would be appreciated besides updating the usage to include the object name.

You can use the syntax export = in the definitions file:

// mapping.d.ts
let mapping: Mapping;
export = mapping;
