I am trying to use a function with the following seems to be simple code.
settings.js
```auto
functionGlobalContext: {
bluebird:require('bluebird')
},
```
function
```auto
const Promise = context.global.bluebird
const p = new Promise((resolve, reject) => {
setTimeout(()=>{
resolve(10)
}),1000
})
p.then(number => {
msg.topic = number
node.warn(msg.topic)
return msg
})
```
and can't return the msg object. In addition, I still did not understand how to properly connect external modules through the setup tab of the function block.

Hello Root,
```auto
const bluebird = global.get("bluebird") // reference library
const p = new Promise((resolve, reject) => {
setTimeout(() => {
resolve(10)
}, 1000)
})
p.then(number => {
msg.topic = "My promise number"
msg.payload = number
//node.warn(msg.topic)
node.send(msg)
})
```
1. you were referencing the library wrong ([Documentation](https://nodered.org/docs/user-guide/writing-functions#using-the-functionglobalcontext-option))
2. you had the ms timeout outside the brackets
3. dont know what the library does .. thats up to you 😉

thank you very much.
Truly, asynchronous need to be returned via `node.send(msg)` 😌

Do not use `bluebird`. There is no good reason for using that library these days. All supported versions of node.js have full support for `Promise` built in.

I'm just studying the tool I'm trying to work with. I am reading this wonderful forum and I am asking questions that are incomprehensible to me. But first, in order not to distract the community, I try to figure it out on my own. I think many people do this. Although the above example was simple, it still allowed me to go further. Thank you sincerely for your wonderful knowledge.
