Hi, I need your help about external module  
I try to use [faux-api-client](https://www.npmjs.com/package/faux-api-client) and I added it in settings.js and restart.

Here is my function code :

```auto
var fauxapi = context.global.fauxapi;
console.log(fauxapi);
const client = new fauxapi ( 'https://192.168.1.1', 'PFFA6', 'qes1sgg81YuyC8s' );
msg.payload = client;
return msg;

```

I get this return in console

```auto

{ FauxApiClient: [Function: FauxApiClient] }

25 Mar 14:37:23 - [error] [function:6dd44643.560218] TypeError: fauxapi is not a constructor

```

I don't understand why.

Here is my settings.js :

```auto
    functionGlobalContext: {
        // os:require('os'),
        // octalbonescript:require('octalbonescript'),
        // jfive:require("johnny-five"),
        // j5board:require("johnny-five").Board({repl:false})
        fcm:require('fcm-node'),
        fauxapi:require('faux-api-client')
    },

```

fcm-node works great.

Thank you for your help  
Thomas

try:

```auto
var fauxapi = global.get("fauxapi");

```

and make sure you did the `npm install faux-api-client` from your nodered directory. Eg '~/.node-red' on a raspberry.

I Don't understand because I did the same with fcm-node and it works.  
Can it due to this package in particulary?

</div>

As I can see It need

```auto
import {FauxApiClient, IFauxApiResponse} from 'faux-api-client';

```

instead of require, does it can make any difference?

Ok I have found my mistake.  
In this case I need to call :

```auto
const fauxapi = global.get("fauxapi.FauxApiClient");

```

Thanks for your help
