I am trying to access a standalone library in a function node and the approach shown in generic nodejs examples for the require command looks like this:  
`const sgMail = require('@sendgrid/mail');`

I have added the following (including some other modules which work) to the .node-red folder in settings.js under functionGlobalContext:  
`sgMail: require('@sendgrid/mail')`

and the following at the top of my function node:  
`var sgMail = global.get("@sendgrid/mail");`

Then when this is executed:  
`sgMail.setApiKey(process.env.SENDGRID_API_KEY);`

It returns the following which I think indicates that the sendgrid module never got loaded.  
`"TypeError: Cannot read property 'setApiKey' of undefined"`

Looking for advice and the meaning of the @ character in the `require('@sendgrid/mail')` syntax.

Any help appreciated. - Thanks in advance.

**Edit** - This has also been added to the **/.node-red** folder's **package.json** file:

```auto
"dependencies": {
        "@sendgrid/mail": "^7.2.6",

```

> Node-RED version: v1.1.3  
> Node.js version: v10.22.0  
> Linux 5.4.0-1024-gcp x64 LE

You can probably test that the require worked. I suspect that it is the `global.get` is what fails because of the embedded `@` symbol. If so, that is an edge case that will need handling in core. One for Nick or Dave.

I have a similar problem with uibuilder that I've not managed to fix yet.

@christl if you have added `sgMail: require('@sendgrid/mail')` to the `functionGlobalContext` value in your settings file, then you would do:

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

```

in your Function node. This is because you are setting the `sgMail`global context value.

Doh! Missed that complexly - blaming lack of coffee input. Will shut down and reboot myself.
