I have updated this question fully as a few people have directed me to other posts with the same issue. Unfortunately, I have tried NodeIntergration and Contextisolation.
From what I can see it is a preload.js issue and im not passing the node moduals and jquery to the powershell.js file correctly, and thats what is giving me the require not defined error
"Uncaught ReferenceError: require is not defined at PowerShell.js:2:11"
I have looked over the Electron documentation on security and preload scripts and cant make any sense of where I am going wrong.
The aim is to just get the Powershell.js script to print to the consel the sentence.
Thanks in advance. :-) Mark
