Hello!
I need nullengine and typescript based project for my perpose, but I have a problem (as it is server-side project,there are no playground code).
As I have seen in previous forums[[Basic setup of running Babylon.js NullEngine with server side (node.js) using TypeScript](https://forum.babylonjs.com/t/basic-setup-of-running-babylon-js-nullengine-with-server-side-node-js-using-typescript/15817)], with a small sample it works, but when I add the code for loading models, bjs requires xhr2.
Therefore, the following code will not work.
```auto
import { NullEngine, Scene, SceneLoader } from "@babylonjs/core";
import "@babylonjs/loaders/glTF";
export const main = () => {
const engine = new NullEngine();
const scene = new Scene(engine);
SceneLoader.ImportMesh("", "sample/", "dummy2.babylon", scene, () => {
console.log("success!");
});
};
```
* * *
The problem is that the project is in Typescript, require() is not available, so I use import syntax, but XMLHttpRequest is inferred to be of type “any” and I can’t avoid this.
```auto
import { NullEngine, Scene, SceneLoader } from "@babylonjs/core";
import "@babylonjs/loaders/glTF";
import XMLHttpRequest from "xhr2"; // Error : XMLHttpRequest has an implicit `any` type
export const main = () => {
global.XMLHttpRequest = XMLHttpRequest;
const engine = new NullEngine();
const scene = new Scene(engine);
SceneLoader.ImportMesh("", "sample/", "dummy2.babylon", scene, () => {
console.log("success!");
});
};
```
Furthermore, if the code were to work with `strict: false` (Yeah, this is not good), the following error would also occur.
```auto
BJS - [19:19:52]: Babylon.js v5.37.0 - Null engine
/home/udemegane/workspace/bjs-serverside-sample/node_modules/xhr2/lib/xhr2.js:281
throw new NetworkError(`Unsupported protocol ${this._url.protocol}`);

at Function.ImportMesh (file:///home/udemegane/workspace/bjs-serverside-sample/lts/core/generated/Loading/sceneLoader.ts:765:28)
```
Looking at the babylonjs source code, there should be a way around this since the Loader unit test is done on the server side, but I don’t know.
Can someone please help!!! Thanks!

Try this:
```auto
import xhr2 from 'xhr2'
// @ts-ignore
global.XMLHttpRequest = xhr2.XMLHttpRequest
```
EDIT: Oops yeah you probably did this 😃

About the message `Unsupported protocol ${this._url.protocol}` even if your file is local the import must be done threw the http protocol so your first parameter has to be set :
```auto
SceneLoader.ImportMesh("http://localhost/XXX", "sample/", "dummy2.babylon", scene, () => {
console.log("success!");
});
```

Was just about to type this as well. You basically need a web server (even static) running.

I delivered from the local server and everything worked fine. Thank you!
