Uncaught ReferenceError: require is not defined at main.html:5

[iCrashed]

The line const electron = require("electron");

in the client script is giving me the error

Verify if your BrowserWindow function has the webPreferences value, with a nodeIntegrations: true. It will resolve your problem with the error of require. See more here https://stackoverflow.com/questions/44391448/electron-require-is-not-defined

Try this as @LuC4SC4S said.

  let mainWindow = new BrowserWindow({
    height: 800,
    width: 800,
    show: false,
    webPreferences: {
      nodeIntegration: true,
    },
  });
