javascript - Problems using node-serialport in my React.js-app

Question

I am trying to run node-serialport in my React app, but I get the following error:

It seems as if running node-serialport in my react-app, all the dependencies aren't loaded correctly.

I have tried to replicate this in a "vanilla" node-app, but then it works just fine.

So, the following works in a clean node-app, but not in a react-app:

1. Install using npm install serialport

const SerialPort = require('serialport')

let myPort = new SerialPort(...);

What could be the cause?

I am very new to React.js, and this might thus be a silly problem.

My "backup" plan would be to have an express-server running locally on the same machine and listening for requests such as /writeToSerialPort, but it would be awesome to just have this little thing work directly in the react-app, as this is quite a small project.

Thanks in advance!

HINT: The same problem is sort of described here, but it seemed to be different causes.
