What steps will reproduce the bug?

Using serialport in an electron-ionic project in the renderer side. Serialport package is installed and loaded into the project as follows in the serialport service constructor:

this.serialport = window.require('serialport');

The project works and serialport list function works when the electron window is opened using the command npx cap open @capacitor-community/electron.

There are 2 issues afterwhich:

1. The port creation doesn't work and but doesn't throw any error to analyse the issue. Also tried adding it with a catch statement. this.port= new this.serialport .SerialPort(serialDevice.name, { baudRate: 9600, autoOpen: false });
2. After building the electron project using electron-builder, the serialport module isn't detected anymore and throws the error 'Cannot find module serialport'.

What happens?

In an electron-ionic project, the serialport package (v10.0.0) works when the electron window is opened in Dev mode using 'npx cap open @capacitor-community/electron' but it throws an error "Cannot find module 'serialport'" when the project is build using electron-builder.

What should have happened?

Serialport package should work with the build exe as well.

I recommend putting Serialport on the main process and not the renderer process. You can use Electron's IPC handlers to call your serialport interface from the renderer process.
