I am trying to use dialog when a user clicks button, bug got an error Uncaught TypeError: Cannot read property 'dialog' of undefined. The result from the console log is undefined
main.js file
const { app, BrowserWindow } = require('electron');
const path = require('path');
if (require('electron-squirrel-startup')) {
app.quit();
}
const createWindow = () => {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true
}
});
mainWindow.loadFile(path.join(__dirname, './src/index.html'));
mainWindow.webContents.openDevTools();
};
app.on('ready', createWindow);
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
if (BrowserWindow.getAllWindows().length === 0) {
createWindow();
}
});

Reset to default 7webPreferences: {
nodeIntegration: true,
enableRemoteModule: true
}
Add enableRemoteModule. I think you are using the latest version of Electron and we can't use remote module on renderer by default. Need to add this flag to enable this.
