Tips for bringing in a class that has been exported from a module

I have a typescript file (generated) that is being used in my angular project.

The contents of this file called contracts.ts are as follows:

export module A.B.C.Models {
  export class Activity {
    prop1: number;
    ...
  }
}

I am attempting to use these classes in another file within the same folder, but I am struggling to correctly import the classes and would also like to create an alias for the overly lengthy module name.

import { Activity } from './contracts';

However, the code does not compile and shows the following error:

Can't find module 'contracts'

Since the file is generated each time our database model changes, I am unable to modify it.

Any assistance would be greatly appreciated. Thank you in advance.

If you find yourself utilizing an outdated typescript feature known as internal modules or namespaces (export module A.B.C.Models is similar to export namespace A.B.C.Models), you may choose to import and utilize the class in the following manner:

import * as c from './contracts'

c.A.B.C.Models.Activity

However, it is not recommended to mix JavaScript modules and namespaces. For more insight on this matter, refer to this discussion:

While namespaces are likely here to stay, it is advisable not to use them due to the availability of better, more standardized, and contemporary patterns through module usage. Exporting the class directly allows for easier utilization with the import syntax:

//contacts.ts
export class Activity {
  prop1: number;
   ...
}
//usage.ts
import { Activity } from './contracts';
