Multi-Window Navigation in Electron: The Complete Guide 🚀

If you've ever built an Electron desktop application with multiple pages or windows, you know the challenge: managing navigation that works smoothly in both development and production can be surprisingly complex. Today, I'm sharing practical solutions to this common problem.

The Challenge We All Face

When building desktop apps with Electron, handling multiple pages isn't as straightforward as web applications. You encounter issues like:

Different behavior in dev vs production builds
Window state management across page transitions
File protocol limitations breaking traditional routing
Complex window lifecycle management

Let me show you battle-tested approaches that actually work.

Key Features You Need

Any solid multi-page Electron solution should provide:

Consistent behavior in development and production
Multiple independent windows with isolated navigation
Persistent window states and positions
Fast page transitions without flickering
Type-safe navigation (if using TypeScript)

Installation & Setup

First, let's set up the foundation. In your terminal:

npm install electron react react-dom
# If using React Router
npm install react-router-dom

Implementation Approaches

Approach 1: File-Based Multi-Page

This works great for apps with distinct, independent pages.

** main.js:**

const { app, BrowserWindow } = require('electron');
const path = require('path');

function createMainWindow() {
  const mainWindow = new BrowserWindow({
    width: 1200,
    height: 800,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
      contextIsolation: true,
      nodeIntegration: false
    }
  });


  if (process.env.NODE_ENV === 'development') {
    mainWindow.loadURL('http://localhost:3000');
  } else {
    mainWindow.loadFile(path.join(__dirname, '../build/index.html'));
  }

  return mainWindow;
}

function createSettingsWindow() {
  const settingsWindow = new BrowserWindow({
    width: 800,
    height: 600,
    parent: mainWindow,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }
  });

  if (process.env.NODE_ENV === 'development') {
    settingsWindow.loadURL('http://localhost:3000/#/settings');
  } else {
    settingsWindow.loadFile(
      path.join(__dirname, '../build/index.html'),
      { hash: 'settings' }
    );
  }

  return settingsWindow;
}

Approach 2: Single Window with Dynamic Routes

Better for apps with frequent navigation between pages.

App Structure:

import { MemoryRouter, Routes, Route } from 'react-router-dom';

function App() {
  return (
    <MemoryRouter>
      <Routes>
        <Route path="/" element={<HomePage />} />
        <Route path="/settings" element={<SettingsPage />} />
        <Route path="/profile" element={<ProfilePage />} />
      </Routes>
    </MemoryRouter>
  );
}

Why MemoryRouter? It keeps navigation in memory rather than the URL bar, perfect for desktop apps.

Window Management Best Practices

Persistent Window States:

const Store = require('electron-store');
const store = new Store();

function createWindowWithState(windowId) {
  const savedState = store.get(`window.${windowId}`, {
    width: 800,
    height: 600,
    x: undefined,
    y: undefined
  });

  const window = new BrowserWindow({
    ...savedState,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }
  });

  // Save state on close
  window.on('close', () => {
    store.set(`window.${windowId}`, window.getBounds());
  });

  return window;
}

Prevent Duplicate Windows:

const activeWindows = new Map();

function openWindow(windowId, options) {
  // Return existing window if already open
  if (activeWindows.has(windowId)) {
    const window = activeWindows.get(windowId);
    window.focus();
    return window;
  }

  const window = new BrowserWindow(options);
  activeWindows.set(windowId, window);

  window.on('closed', () => {
    activeWindows.delete(windowId);
  });

  return window;
}

Inter-Window Communication

Preload Script:

const { contextBridge, ipcRenderer } = require('electron');

contextBridge.exposeInMainWorld('electronAPI', {
  openWindow: (windowId) => ipcRenderer.send('open-window', windowId),
  sendToWindow: (windowId, data) => 
    ipcRenderer.send('send-to-window', windowId, data),
  onMessage: (callback) => 
    ipcRenderer.on('window-message', (_, data) => callback(data))
});

Main Process Handler:

ipcMain.on('send-to-window', (event, targetWindowId, data) => {
  const targetWindow = activeWindows.get(targetWindowId);
  if (targetWindow) {
    targetWindow.webContents.send('window-message', data);
  }
});

Navigation Component

Create a reusable navigation component:

function Navigation() {
  const navigate = useNavigate();

  const handleOpenSettings = () => {
    window.electronAPI.openWindow('settings');
  };

  return (
    <nav className="app-nav">
      <button onClick={() => navigate('/')}>Home</button>
      <button onClick={() => navigate('/profile')}>Profile</button>
      <button onClick={handleOpenSettings}>Settings (New Window)</button>
    </nav>
  );
}

Production Build Configuration

package.json scripts:

{
  "scripts": {
    "dev": "concurrently \"npm run dev:react\" \"npm run dev:electron\"",
    "dev:react": "vite",
    "dev:electron": "wait-on http://localhost:3000 && electron .",
    "build": "vite build && electron-builder"
  }
}

Common Pitfalls to Avoid

Don't use BrowserRouter - It relies on URL changes which don't work well with the file protocol
Always handle both dev and production - Paths differ significantly
Never forget contextIsolation - It's a critical security feature
Avoid memory leaks - Always remove event listeners on window close
Test production builds - Dev mode can hide issues

Performance Tips

// Lazy load heavy components
const SettingsPage = lazy(() => import('./pages/Settings'));

// Preload next likely page
const preloadPage = (path) => {
  const link = document.createElement('link');
  link.rel = 'prefetch';
  link.href = path;
  document.head.appendChild(link);
};
