Why Does My Electron App Throw a \'require() is not defined\' Error in HTML Pages?

Electron: Resolving "require() is not defined" Issue in HTML Pages

When developing Electron applications, incorporating Node.js functionality into HTML pages can lead to the perplexing error "require() is not defined." This occurs due to a change in Electron's default settings in its later versions.

To address this issue, users need to explicitly enable nodeIntegration when creating Browser Windows. This allows the HTML pages to access the required Node.js modules and global objects. Here's an example:

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

Once this setting is enabled, variables like the following can be seamlessly used within HTML pages:

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

By enabling nodeIntegration, Electron grants HTML pages access to the Node.js environment, allowing users to leverage its functionalities and objects throughout their application's interface.
