electron: Uncaught ReferenceError: require is not defined

in your index.js

const w = new BrowserWindow({ webPreferences: { nodeIntegration: true } })

actually i added nodeIntergration = true but dosent work still

Assuming electron 12.0.0

set contextIsolation: false

Something like…

webPreferences: {
      nodeIntegration: true,
      contextIsolation: false,
      enableRemoteModule: true,
    }

The default for nodeIntegration changed from true to false as per our breaking changes document.

@brntsllvn Adding

webPreferences: {
      nodeIntegration: true,
      contextIsolation: false,
      enableRemoteModule: true,
    }

Works like a charm!! Thing is, do these other properties affect your application in any way?

Regards,

Need to change webPreferences.nodeIntegration to true when new BrowserWindow mainWindow = new BrowserWindow({ width: 1000, height: 600, webPreferences: { nodeIntegration: true } });

It didn’t work for me because webPreferences.contextIsolation was set to true. Be careful when setting that option to false though https://www.electronjs.org/docs/tutorial/context-isolation#security-considerations.

setting nodeIntegration to true is the easy way, bu keeping it false is more secure as documentation tells, I ve found this https://stackoverflow.com/questions/52236641/electron-ipc-and-nodeintegration that may help future readers.
