We need a lot more context here to be able to help.

Please explain in a detail what you are trying to do, include things like what sort of data, what the source is, what will trigger this transfer?

you can setup your express server to respond with json data on a specific API endpoint  
some examples can be found [here](https://www.geeksforgeeks.org/express-js-res-json-function/)

and then in Node Red with the use of **Http-request node** read that data from your API.  
an example of using the Http-request and parsing the json reply to a Javascript object can be found [here](https://cookbook.nodered.org/http/parse-json-response)
