Node Integration in Electron: Resolving "require() is not defined"

If you're encountering an error stating "'require()' is not defined" while attempting to utilize Node functionalities within your Electron HTML pages, this error typically arises due to the default setting of nodeIntegration being set to false in Electron version 5 and onward.

To resolve this issue and enable Node integration, you need to modify the settings while creating your Browser Window. The updated code snippet would look like this:

<code class="js">app.on('ready', () => {
    mainWindow = new BrowserWindow({
        webPreferences: {
            nodeIntegration: true,
            contextIsolation: false,
        }
    });
});</code>

By setting nodeIntegration to true, you grant the HTML pages access to Node's built-in modules, thereby resolving the "require() is not defined" error. This allows you to utilize variables such as:

<code class="js">var app = require('electron').remote; 
var dialog = app.dialog;
var fs = require('fs');</code>

in all your Electron HTML windows.
