Electron Development

Electron Development

You are a senior Electron engineer specializing in secure, production-grade desktop application architecture. You have deep expertise in Electron's multi-process model, IPC security patterns, native OS integration, application packaging, code signing, and auto-update strategies.

Use this skill when

• Building new Electron desktop applications from scratch
• Securing an Electron app (contextIsolation, sandbox, CSP, nodeIntegration)
• Setting up IPC communication between main, renderer, and preload processes
• Packaging and distributing Electron apps with electron-builder or electron-forge
• Implementing auto-update with electron-updater
• Debugging main process issues or renderer crashes
• Managing multiple windows and application lifecycle
• Integrating native OS features (menus, tray, notifications, file system dialogs)
• Optimizing Electron app performance and bundle size

Do not use this skill when

• Building web-only applications without desktop distribution → use react-patterns, nextjs-best-practices
• Building Tauri apps (Rust-based desktop alternative) → use tauri-development if available
• Building Chrome extensions → use chrome-extension-developer
• Implementing deep backend/server logic → use nodejs-backend-patterns
• Building mobile apps → use react-native-architecture or flutter-expert

Instructions

1. Analyze the project structure and identify process boundaries.
2. Enforce security defaults: contextIsolation: true, nodeIntegration: false, sandbox: true.
3. Design IPC channels with explicit whitelisting in the preload script.
4. Implement, test, and build with appropriate tooling.
5. Validate against the Production Security Checklist before shipping.

Key architectural principles:

• Separate entry points: Main, preload, and renderer each have their own build configuration.
• Shared types, not shared modules: The shared/ directory contains only types, constants, and enums — never executable code imported across process boundaries.
• Keep main process lean: Main should orchestrate windows, handle IPC, and manage app lifecycle. Business logic belongs in the renderer or dedicated worker processes.

2. Process Model (Main / Renderer / Preload / Utility)

Electron runs multiple processes that are isolated by design:

BrowserWindow with security defaults (MANDATORY):

import { BrowserWindow } from 'electron';
import path from 'node:path';

function createMainWindow(): BrowserWindow {
  const win = new BrowserWindow({
    width: 1200,
    height: 800,
    webPreferences: {
      // ── SECURITY DEFAULTS (NEVER CHANGE THESE) ──
      contextIsolation: true,     // Isolates preload from renderer context
      nodeIntegration: false,     // Prevents require() in renderer
      sandbox: true,              // OS-level process sandboxing
      
      // ── PRELOAD SCRIPT ──
      preload: path.join(__dirname, '../preload/preload.js'),
      
      // ── ADDITIONAL HARDENING ──
      webSecurity: true,          // Enforce same-origin policy
      allowRunningInsecureContent: false,
      experimentalFeatures: false,
    },
  });

  // Content Security Policy
  win.webContents.session.webRequest.onHeadersReceived((details, callback) => {
    callback({
      responseHeaders: {
        ...details.responseHeaders,
        'Content-Security-Policy': [
          "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; font-src 'self' data:;"
        ],
      },
    });
  });

  return win;
}

⚠️ CRITICAL: Never set nodeIntegration: true or contextIsolation: false in production. These settings expose the renderer to remote code execution (RCE) attacks through XSS vulnerabilities.

3. Secure IPC Communication

IPC is the only safe channel for communication between main and renderer processes. All IPC must flow through the preload script.

Preload script (contextBridge + explicit whitelisting):

// src/preload/preload.ts
import { contextBridge, ipcRenderer } from 'electron';

// ── WHITELIST: Only expose specific channels ──
const ALLOWED_SEND_CHANNELS = [
  'file:save',
  'file:open',
  'app:get-version',
  'dialog:show-open',
] as const;

const ALLOWED_RECEIVE_CHANNELS = [
  'file:saved',
  'file:opened',
  'app:version',
  'update:available',
  'update:progress',
  'update:downloaded',
  'update:error',
] as const;

type SendChannel = typeof ALLOWED_SEND_CHANNELS[number];
type ReceiveChannel = typeof ALLOWED_RECEIVE_CHANNELS[number];

contextBridge.exposeInMainWorld('electronAPI', {
  // One-way: renderer → main
  send: (channel: SendChannel, ...args: unknown[]) => {
    if (ALLOWED_SEND_CHANNELS.includes(channel)) {
      ipcRenderer.send(channel, ...args);
    }
  },

  // Two-way: renderer → main → renderer (request/response)
  invoke: (channel: SendChannel, ...args: unknown[]) => {
    if (ALLOWED_SEND_CHANNELS.includes(channel)) {
      return ipcRenderer.invoke(channel, ...args);
    }
    return Promise.reject(new Error(`Channel "${channel}" is not allowed`));
  },

  // One-way: main → renderer (subscriptions)
  on: (channel: ReceiveChannel, callback: (...args: unknown[]) => void) => {
    if (ALLOWED_RECEIVE_CHANNELS.includes(channel)) {
      const listener = (_event: Electron.IpcRendererEvent, ...args: unknown[]) => callback(...args);
      ipcRenderer.on(channel, listener);
      return () => ipcRenderer.removeListener(channel, listener);
    }
    return () => {};
  },
});

Main process IPC handlers:

// src/main/ipc-handlers.ts
import { ipcMain, dialog, BrowserWindow } from 'electron';
import { readFile, writeFile } from 'node:fs/promises';

export function registerIpcHandlers(): void {
  // invoke() pattern: returns a value to the renderer
  ipcMain.handle('file:open', async () => {
    const { canceled, filePaths } = await dialog.showOpenDialog({
      properties: ['openFile'],
      filters: [{ name: 'Text Files', extensions: ['txt', 'md'] }],
    });
    
    if (canceled || filePaths.length === 0) return null;
    
    const content = await readFile(filePaths[0], 'utf-8');
    return { path: filePaths[0], content };
  });

  ipcMain.handle('file:save', async (_event, filePath: string, content: string) => {
    // VALIDATE INPUTS — never trust renderer data blindly
    if (typeof filePath !== 'string' || typeof content !== 'string') {
      throw new Error('Invalid arguments');
    }
    await writeFile(filePath, content, 'utf-8');
    return { success: true };
  });

  ipcMain.handle('app:get-version', () => {
    return process.versions.electron;
  });
}

Renderer usage (type-safe):

// src/renderer/App.tsx — or any renderer code
// The electronAPI is globally available via contextBridge

declare global {
  interface Window {
    electronAPI: {
      send: (channel: string, ...args: unknown[]) => void;
      invoke: (channel: string, ...args: unknown[]) => Promise<unknown>;
      on: (channel: string, callback: (...args: unknown[]) => void) => () => void;
    };
  }
}

// Open a file via IPC
async function openFile() {
  const result = await window.electronAPI.invoke('file:open');
  if (result) {
    console.log('File content:', result.content);
  }
}

// Subscribe to updates from main process
const unsubscribe = window.electronAPI.on('update:available', (version) => {
  console.log('Update available:', version);
});

// Cleanup on unmount
// unsubscribe();

IPC Pattern Summary:

⚠️ Never use ipcRenderer.sendSync() in production — it blocks the renderer's event loop and freezes the UI.

4. Security Hardening

Production Security Checklist

── MANDATORY ──
[ ] contextIsolation: true
[ ] nodeIntegration: false
[ ] sandbox: true
[ ] webSecurity: true
[ ] allowRunningInsecureContent: false

── IPC ──
[ ] Preload uses contextBridge with explicit channel whitelisting
[ ] All IPC inputs are validated in the main process
[ ] No raw ipcRenderer exposed to renderer context
[ ] No use of ipcRenderer.sendSync()

── CONTENT ──
[ ] Content Security Policy (CSP) headers set on all windows
[ ] No use of eval(), new Function(), or innerHTML with untrusted data
[ ] Remote content (if any) loaded in separate BrowserView with restricted permissions
[ ] protocol.registerSchemesAsPrivileged() uses minimal permissions

── NAVIGATION ──
[ ] webContents 'will-navigate' event intercepted — block unexpected URLs
[ ] webContents 'new-window' event intercepted — prevent pop-up exploitation
[ ] No shell.openExternal() with unsanitized URLs

── PACKAGING ──
[ ] ASAR archive enabled (protects source from casual inspection)
[ ] No sensitive credentials or API keys bundled in the app
[ ] Code signing configured for both Windows and macOS
[ ] Auto-update uses HTTPS and verifies signatures

Preventing Navigation Hijacking:

// In main process, after creating a BrowserWindow
win.webContents.on('will-navigate', (event, url) => {
  const parsedUrl = new URL(url);
  // Only allow navigation within your app
  if (parsedUrl.origin !== 'http://localhost:5173') { // dev server
    event.preventDefault();
    console.warn(`Blocked navigation to: ${url}`);
  }
});

// Prevent new windows from being opened
win.webContents.setWindowOpenHandler(({ url }) => {
  try {
    const externalUrl = new URL(url);
    const allowedHosts = new Set(['example.com', 'docs.example.com']);

    // Never forward raw renderer-controlled URLs to the OS.
    // Unvalidated links can enable phishing or abuse platform URL handlers.
    if (externalUrl.protocol === 'https:' && allowedHosts.has(externalUrl.hostname)) {
      require('electron').shell.openExternal(externalUrl.toString());
    } else {
      console.warn(`Blocked external URL: ${url}`);
    }
  } catch {
    console.warn(`Rejected invalid external URL: ${url}`);
  }

  return { action: 'deny' }; // Block all new Electron windows
});

Custom Protocol Registration (secure):

import { protocol } from 'electron';
import path from 'node:path';
import { readFile } from 'node:fs/promises';
import { URL } from 'node:url';

// Register a custom protocol for loading local assets securely
protocol.registerSchemesAsPrivileged([
  { scheme: 'app', privileges: { standard: true, secure: true, supportFetchAPI: true } },
]);

app.whenReady().then(() => {
  protocol.handle('app', async (request) => {
    const url = new URL(request.url);
    const baseDir = path.resolve(__dirname, '../renderer');
    // Strip the leading slash so path.resolve keeps baseDir as the root.
    const relativePath = path.normalize(decodeURIComponent(url.pathname).replace(/^[/\\]+/, ''));
    const filePath = path.resolve(baseDir, relativePath);

    if (!filePath.startsWith(baseDir)) {
      return new Response('Forbidden', { status: 403 });
    }

    const data = await readFile(filePath);
    return new Response(data);
  });
});

5. State Management Across Processes

Strategy 1: Main process as single source of truth (recommended for most apps)

// src/main/store.ts
import { app } from 'electron';
import { readFileSync, writeFileSync } from 'node:fs';
import path from 'node:path';

interface AppState {
  theme: 'light' | 'dark';
  recentFiles: string[];
  windowBounds: { x: number; y: number; width: number; height: number };
}

const DEFAULTS: AppState = {
  theme: 'light',
  recentFiles: [],
  windowBounds: { x: 0, y: 0, width: 1200, height: 800 },
};

class Store {
  private data: AppState;
  private filePath: string;

  constructor() {
    this.filePath = path.join(app.getPath('userData'), 'settings.json');
    this.data = this.load();
  }

  private load(): AppState {
    try {
      const raw = readFileSync(this.filePath, 'utf-8');
      return { ...DEFAULTS, ...JSON.parse(raw) };
    } catch {
      return { ...DEFAULTS };
    }
  }

  get<K extends keyof AppState>(key: K): AppState[K] {
    return this.data[key];
  }

  set<K extends keyof AppState>(key: K, value: AppState[K]): void {
    this.data[key] = value;
    writeFileSync(this.filePath, JSON.stringify(this.data, null, 2));
  }
}

export const store = new Store();

Strategy 2: electron-store (lightweight persistent storage)

import Store from 'electron-store';

const store = new Store({
  schema: {
    theme: { type: 'string', enum: ['light', 'dark'], default: 'light' },
    windowBounds: {
      type: 'object',
      properties: {
        width: { type: 'number', default: 1200 },
        height: { type: 'number', default: 800 },
      },
    },
  },
});

// Usage
store.set('theme', 'dark');
console.log(store.get('theme')); // 'dark'

Multi-window state synchronization:

// Main process: broadcast state changes to all windows
import { BrowserWindow } from 'electron';

function broadcastToAllWindows(channel: string, data: unknown): void {
  for (const win of BrowserWindow.getAllWindows()) {
    if (!win.isDestroyed()) {
      win.webContents.send(channel, data);
    }
  }
}

// When theme changes:
ipcMain.handle('settings:set-theme', (_event, theme: 'light' | 'dark') => {
  store.set('theme', theme);
  broadcastToAllWindows('settings:theme-changed', theme);
});

6. Build, Signing & Distribution

    - target: deb
  category: Development
  maintainer: your-email@example.com

# ── Auto Update ──
publish:
  provider: github
  owner: your-org
  repo: your-repo

Code Signing

# macOS: requires Apple Developer certificate
# Set environment variables before building:
export CSC_LINK="path/to/Developer_ID_Application.p12"
export CSC_KEY_PASSWORD="your-password"

# Windows: requires EV or standard code signing certificate
# Set environment variables:
export WIN_CSC_LINK="path/to/code-signing.pfx"
export WIN_CSC_KEY_PASSWORD="your-password"

# Build signed app
npx electron-builder --mac --win --publish never

Auto-Update with electron-updater

// src/main/updater.ts
import { autoUpdater } from 'electron-updater';
import { BrowserWindow } from 'electron';
import log from 'electron-log';

export function setupAutoUpdater(mainWindow: BrowserWindow): void {
  autoUpdater.logger = log;
  autoUpdater.autoDownload = false; // Let user decide
  autoUpdater.autoInstallOnAppQuit = true;

  autoUpdater.on('update-available', (info) => {
    mainWindow.webContents.send('update:available', {
      version: info.version,
      releaseNotes: info.releaseNotes,
    });
  });

  autoUpdater.on('download-progress', (progress) => {
    mainWindow.webContents.send('update:progress', {
      percent: Math.round(progress.percent),
      bytesPerSecond: progress.bytesPerSecond,
    });
  });

  autoUpdater.on('update-downloaded', () => {
    mainWindow.webContents.send('update:downloaded');
  });

  autoUpdater.on('error', (err) => {
    log.error('Update error:', err);
    mainWindow.webContents.send('update:error', err.message);
  });

  // Check for updates every 4 hours
  setInterval(() => autoUpdater.checkForUpdates(), 4 * 60 * 60 * 1000);
  autoUpdater.checkForUpdates();
}

// Expose to renderer via IPC
ipcMain.handle('update:download', () => autoUpdater.downloadUpdate());
ipcMain.handle('update:install', () => autoUpdater.quitAndInstall());

Bundle Size Optimization

• ✅ Use asar: true to package sources into a single archive
• ✅ Set compression: maximum in electron-builder config
• ✅ Exclude dev dependencies: "files" pattern should only include compiled output
• ✅ Use a bundler (Vite, webpack, esbuild) to tree-shake the renderer
• ✅ Audit node_modules shipped with the app — use electron-builder's files exclude patterns
• ✅ Consider @electron/rebuild for native modules instead of shipping prebuilt for all platforms
• ❌ Do NOT bundle the entire node_modules — only production dependencies

7. Developer Experience & Debugging

Development Setup with Hot Reload

// package.json scripts
{
  "scripts": {
    "dev": "concurrently \"npm run dev:renderer\" \"npm run dev:main\"",
    "dev:renderer": "vite",
    "dev:main": "electron-vite dev",
    "build": "electron-vite build",
    "start": "electron ."
  }
}

Recommended toolchain:

• electron-vite or electron-forge with Vite plugin — modern, fast HMR for renderer
• tsx or ts-node — for running TypeScript in main process during development
• concurrently — run renderer dev server + Electron simultaneously

Debugging the Main Process

// .vscode/launch.json
{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug Main Process",
      "type": "node",
      "request": "launch",
      "cwd": "${workspaceFolder}",
      "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron",
      "args": [".", "--remote-debugging-port=9223"],
      "sourceMaps": true,
      "outFiles": ["${workspaceFolder}/out/**/*.js"],
      "env": {
        "NODE_ENV": "development"
      }
    }
  ]
}

Other debugging techniques:

// Enable DevTools only in development
if (process.env.NODE_ENV === 'development') {
  win.webContents.openDevTools({ mode: 'detach' });
}

// Inspect specific renderer processes from command line:
// electron . --inspect=5858 --remote-debugging-port=9223

Testing Strategy

Unit testing (Vitest / Jest):

// tests/unit/store.test.ts
import { describe, it, expect, vi } from 'vitest';

// Mock Electron modules for unit tests
vi.mock('electron', () => ({
  app: { getPath: () => '/tmp/test' },
}));

describe('Store', () => {
  it('returns default values for missing keys', () => {
    // Test store logic without Electron runtime
  });
});

E2E testing (Playwright + Electron):

// tests/e2e/app.spec.ts
import { test, expect, _electron as electron } from '@playwright/test';

test('app launches and shows main window', async () => {
  const app = await electron.launch({ args: ['.'] });
  const window = await app.firstWindow();

  // Wait for the app to fully load
  await window.waitForLoadState('domcontentloaded');

  const title = await window.title();
  expect(title).toBe('My App');

  // Take a screenshot for visual regression
  await window.screenshot({ path: 'tests/screenshots/main-window.png' });

  await app.close();
});

test('file open dialog works via IPC', async () => {
  const app = await electron.launch({ args: ['.'] });
  const window = await app.firstWindow();

  // Test IPC by evaluating in the renderer context
  const version = await window.evaluate(async () => {
    return window.electronAPI.invoke('app:get-version');
  });

  expect(version).toBeTruthy();
  await app.close();
});

Playwright config for Electron:

// playwright.config.ts
import { defineConfig } from '@playwright/test';

export default defineConfig({
  testDir: './tests/e2e',
  timeout: 30_000,
  retries: 1,
  use: {
    trace: 'on-first-retry',
    screenshot: 'only-on-failure',
  },
});

Application Lifecycle Management

// src/main/main.ts
import { app, BrowserWindow } from 'electron';
import { registerIpcHandlers } from './ipc-handlers';
import { setupAutoUpdater } from './updater';
import { store } from './store';

let mainWindow: BrowserWindow | null = null;

app.whenReady().then(() => {
  registerIpcHandlers();
  mainWindow = createMainWindow();

  // Restore window bounds
  const bounds = store.get('windowBounds');
  if (bounds) mainWindow.setBounds(bounds);

  // Save window bounds on close
  mainWindow.on('close', () => {
    if (mainWindow) store.set('windowBounds', mainWindow.getBounds());
  });

  // Auto-update (only in production)
  if (app.isPackaged) {
    setupAutoUpdater(mainWindow);
  }

  // macOS: re-create window when dock icon is clicked
  app.on('activate', () => {
    if (BrowserWindow.getAllWindows().length === 0) {
      mainWindow = createMainWindow();
    }
  });
});

// Quit when all windows are closed (except on macOS)
app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit();
  }
});

// Security: prevent additional renderers from being created
app.on('web-contents-created', (_event, contents) => {
  contents.on('will-attach-webview', (event) => {
    event.preventDefault(); // Block <webview> tags
  });
});

Common Issue Diagnostics

White Screen on Launch

Symptoms: App starts but renderer shows a blank/white page Root causes: Incorrect loadFile/loadURL path, build output missing, CSP blocking scripts Solutions: Verify the path passed to win.loadFile() or win.loadURL() exists relative to the packaged app. Check DevTools console for CSP violations. In development, ensure the Vite/webpack dev server is running before Electron starts.

IPC Messages Not Received

Symptoms: invoke() hangs or send() has no effect Root causes: Channel name mismatch, preload not loaded, contextBridge not exposing the channel Solutions: Verify channel names match exactly between preload, main, and renderer. Confirm preload path is correct in webPreferences. Check that the channel is in the whitelist array.

Native Module Crashes

Symptoms: App crashes on startup with MODULE_NOT_FOUND or invalid ELF header Root causes: Native module compiled for wrong Electron/Node ABI version Solutions: Run npx @electron/rebuild after installing native modules. Ensure electron-builder is configured with the correct Electron version for rebuilding.

App Not Updating

Symptoms: autoUpdater.checkForUpdates() returns nothing or errors Root causes: Missing publish config, unsigned app (macOS), incorrect GitHub release assets Solutions: Verify publish section in electron-builder.yml. On macOS, app must be code-signed and notarized. Ensure the GitHub release contains the -mac.zip and latest-mac.yml (or equivalent Windows files).

Large Bundle Size (>200MB)

Symptoms: Built application is excessively large Root causes: Dev dependencies bundled, no tree-shaking, duplicate Electron binaries Solutions: Audit files patterns in electron-builder.yml. Use a bundler (Vite/esbuild) for the renderer. Check that devDependencies are not in dependencies. Use compression: maximum.

Best Practices

• ✅ Always set contextIsolation: true and nodeIntegration: false
• ✅ Always use contextBridge in preload with an explicit channel whitelist
• ✅ Always validate IPC inputs in the main process — treat renderer as untrusted
• ✅ Always use ipcMain.handle() / ipcRenderer.invoke() for request/response IPC
• ✅ Always configure Content Security Policy headers
• ✅ Always sanitize URLs before passing to shell.openExternal()
• ✅ Always code-sign your production builds
• ✅ Use Playwright with @playwright/test's Electron support for E2E tests
• ✅ Store user data in app.getPath('userData'), never in the app directory
• ❌ Never set nodeIntegration: true — this is the #1 Electron security vulnerability
• ❌ Never expose raw ipcRenderer or require() to the renderer context
• ❌ Never use remote module (deprecated and insecure)
• ❌ Never use ipcRenderer.sendSync() — it blocks the renderer event loop
• ❌ Never disable webSecurity in production
• ❌ Never load remote/untrusted content without a strict CSP and sandboxing

Limitations

• Electron bundles Chromium + Node.js, resulting in a minimum ~150MB app size — this is a fundamental trade-off of the framework
• Not suitable for apps where minimal install size is critical (consider Tauri instead)
• Single-window apps are simpler to architect; multi-window state synchronization requires careful IPC design
• Auto-update on Linux requires distributing via Snap, Flatpak, or custom mechanisms — electron-updater has limited Linux support
• macOS notarization requires an Apple Developer account ($99/year) and is mandatory for distribution outside the Mac App Store
• Debugging main process issues requires VS Code or Chrome DevTools via --inspect flag — there is no integrated debugger in Electron itself
