Creating a TypeScript definition file that exports a class after instantiation

Currently, I am struggling with a specific typescript definition that is not functioning as expected:

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

This setup allows for the following usage:

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

Unfortunately, I am unable to figure out the correct structure for my mapping.d.ts file to make this work, and it fails to compile.

mapping.d.ts
export var mapping: Mapping;

The issue here is that the usage would then need to be:

_mapping.mapping.doSomething();

If you have any suggestions on how to resolve this without changing the object name in the usage, I would greatly appreciate it.

Answer №1

Incorporate the export = syntax into your definitions file by following this example:

// defineMapping.d.ts
let mapping: DefinedMapping;
export = mapping;
