Use mongodb types definitions in my own definitions file

Question

I have a problem with TypeScript imports :

Here is my mydef.d.ts:

import * as mongodb from "mongodb";
interface UserDto {
    _id: mongodb.ObjectID;
    username: string;
}

And here is my main.ts:

import * as mongodb from "mongodb";
let user: UserDto = {
    _id: new mongodb.ObjectID("anyID"),
    username: "Xstoudi"
}

But in main.ts: Cannot find name UserDto.

Thanks !

First you have to export your interface in mydef.d.ts.

import * as mongodb from "mongodb";
export interface UserDto {
    _id: mongodb.ObjectID;
    username: string;
}

Then you need to import it in main.ts, the same way you import mongo.

import * as mongodb from "mongodb";
import {UserDto} from "mydef";
let user: UserDto = {
    _id: new mongodb.ObjectID("anyID"),
    username: "Xstoudi"
}
