Hi,  
I am looking for a method to retrieve the name of the global variables as well as their value.

For the moment, I only manage to have an array with the values:  
global.get (global.keys ())

I can't get the name of the variables the same way they are displayed in the context

![Sans titre](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/6/e6869a386e4e3542baa668f6c47ef7efe85b361c.png)

Can anyone tell me how to do this?  
thanks

Usually you know the global property you used to save the value in the first place and you retrieve it with  
For example: `let progress1 = global.get('progress1')`

You could use a Function node to generate the list by looping through the keys

```javascript
let list = []

global.keys().forEach( key => {
    list.push( { [key]: global.get(key)});
})

msg.payload = list
return msg

```

To use global.keys(), you need to have the following in settings.js:

```auto
exportGlobalContextKeys: true,

```

Since that is actually a bit of a security issue if you allow people access to the full list all the time.

Thats strange .. i checked my `settings.js` and indeed its set to `exportGlobalContextKeys: false` by default but the above code run regardless.

Node-RED version: v2.0.5  
Node.js version: v14.16.0

Ah, interesting, is that a bug I wonder?

@Xeniluom cool .. now that i think of it maybe it would be more easily accesible if the list was an object.

```javascript
let list = {};

global.keys().forEach( key => {
    list[key] = global.get(key);
})

msg.payload = list
return msg

```

@TotallyInformation seems like it.

`exportGlobalContextKeys` controls whether the global context keys set via `functionGlobalContext` are exposed or not.

Any global context properties set in the flow itself will always be returned.
