Introduction
Over 1,300 companies use Electron in production, including Slack, Notion, and GitHub Desktop, according to the Electron project’s official user registry. The framework’s appeal is straightforward: if you can build a website, you can build a desktop app. But the path from working prototype to production-ready application involves decisions most tutorials skip. This guide walks through the full process from project structure to packaging and auto-update setup.
What does a production-ready Electron project structure look like?
Electron requires Node.js 18 or higher. The minimum dependencies for a functioning application are the electron package itself and a build tool like electron-forge or electron-builder for packaging. A frontend framework is not required but React and Vue both integrate cleanly for complex UIs.
A full breakdown of the electron application framework architecture, including how it compares to Tauri and Flutter for cross-platform desktop development, is available with framework selection criteria and real build benchmarks.
Electron runs two types of processes: the main process for Node.js and OS integrations, and renderer processes for the Chromium-based UI. Keeping these concerns separated from the start prevents the most common architectural mistakes. Main process code goes in /src/main, renderer code in /src/renderer, and shared utilities in /src/shared.
How should security be configured in an Electron application?
Electron’s biggest security risk is enabling nodeIntegration in renderer processes. This gives web-rendered code direct access to Node.js APIs, which creates a significant attack surface if the application loads any remote content.
The secure approach is to disable nodeIntegration, enable contextIsolation, and use a preload script to expose only the specific APIs the renderer needs. Setting webPreferences.nodeIntegration to false, webPreferences.contextIsolation to true, and using preload scripts for IPC bridges covers the three most critical security configurations. All IPC messages should be validated in the main process, not trusted from the renderer.
How do you package an Electron app for Windows, macOS, and Linux?
electron-forge is the recommended packaging tool for new projects. It handles code signing, installer generation, and platform-specific packaging through a single configuration file. For macOS distribution through the App Store, an Apple Developer account at $99 per year and notarization are required. For Windows, a code signing certificate from a recognized CA prevents Windows Defender warnings on first launch.
Auto-updates are handled by the electron-updater library, which integrates with GitHub Releases and S3 to deliver automatic updates. Users see an update prompt on next launch. Publishing an update is as simple as tagging a new release in the repository. This is the same mechanism VS Code uses for its continuous update cycle.
Frequently Asked Questions
Can Electron apps access local files and system resources?
Yes. The main process has full Node.js access, including the file system, network, and OS APIs. Renderer processes access these through IPC calls to the main process. This separation is intentional for security.
How large is a typical Electron app installer?
Most Electron applications produce installers between 80 MB and 150 MB. The bulk is the bundled Chromium runtime. If installer size is a hard constraint, Tauri achieves similar results with installers under 5 MB by using the OS native WebView instead.
Conclusion
Electron is mature, well-documented, and backed by GitHub. For most development teams building internal tools or productivity applications, it remains the fastest path to a cross-platform desktop product. Start with electron-forge, enforce context isolation from day one, and set up auto-updates before the first public release. Getting these three things right in the initial setup eliminates the most common production issues that cause expensive rewrites later.
