When I run "yarn run electron-dev" in the CLI, opening http://localhost:3000 in the browser is showing the homepage, but the electron app is showing blank.
Unlike similar issues where other people are having issues with production but working in development, I am having the opposite issue.
Looking at the devtools there are no errors in the browser console, and also nothing is coming up in the console even when I do console.log().
electron.js
const electron = require('electron');
const app = electron.app;
const BrowserWindow = electron.BrowserWindow;
const edge = require('electron-edge-js');
const path = require('path');
const isDev = require('electron-is-dev');
require('electron-reload')
let mainWindow;
function createWindow() {
mainWindow = new BrowserWindow({
width: 900,
height: 680,
webPreferences: {
nodeIntegration: true,
},
});
console.log('isDev', isDev);
mainWindow.loadURL(isDev ? 'http://localhost:3000' : `file://${path.join(__dirname, '../build/index.html')}`);
if (isDev) {
// Open the DevTools.
//BrowserWindow.addDevToolsExtension('<location to your react chrome extension>');
mainWindow.webContents.openDevTools();
}
mainWindow.on('closed', () => mainWindow = null);
}
app.on('ready', createWindow);
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
if (mainWindow === null) {
createWindow();
console.log('entering func123');
func123();
}
});
