What is Electron?

Electron is an open-source framework developed by GitHub that allows for building cross-platform desktop applications with web technologies like JavaScript, HTML, and CSS. It is based on Node.js and Chromium, taking advantage of their benefits on the backend and frontend respectively.

The project was first announced in 2013 and open-sourced in 2014. Electron has gained popularity over the years for enabling developers to use their existing web development skills to build desktop apps that work across Windows, macOS, and Linux. Major companies like Microsoft, Slack, Discord, and Visual Studio Code use Electron in their desktop apps.

At its core, Electron consists of two main processes – the main process that handles the backend/API side code in Node.js, and the renderer process that displays the frontend UI with Chromium. This architecture allows accessing native operating system APIs and features in the backend while retaining the familiar web technologies that developers are comfortable with on the front end.

Overall, Electron enables building desktop apps with web technologies to be distributed across multiple platforms. Its active community support and abundant module ecosystem make it a versatile framework for developing cross-platform desktop applications.

Key Components

Electron apps are built using web technologies like HTML, CSS, and JavaScript for the frontend, and Node.js for the backend. This allows developers to leverage their existing web development skills to build cross-platform desktop apps.

The key components that make this possible in Electron are:

The Main and Renderer Processes

Electron runs two different processes – the main process and the renderer process.

The main process, which runs on Node.js, is responsible for managing system-level events and creating renderer processes to display web content. It has full access to Node.js APIs for filesystem access, network calls, and more.

The renderer processes run a separate instance of Chromium for each app window to display the frontend UI. These processes only have access to web-related APIs and don’t have the same system access as the main process. Communication between the two happens over IPC (inter-process communication).

This separation of processes and access provides security – the renderer processes are isolated and can’t access sensitive resources directly.

Using Node.js APIs

The main process allows using Node.js APIs for lower-level operating system interactions like creating and managing files/folders, executing shell commands, making HTTP requests, and more.

For example, you could use the fs module to read/write files, child_process to run other programs, and http/https to make network requests.

Chromium for Displaying Content

The renderer processes use Chromium to display web content like HTML, CSS, and JavaScript. This provides access to DOM manipulation APIs, web APIs like localStorage, and more.

Developers can use their existing web development skills to build the frontend UI. The Chromium instance runs in isolation for security but can communicate with the backend main process over IPC.

This combination of standard web technologies using Chromium, and Node.js backend access, makes Electron a powerful framework for building cross-platform desktop applications using JavaScript.

Benefits

Electron provides several key benefits for building desktop applications with web technologies:

Write Once, Run Anywhere

One of the biggest advantages of Electron is the ability to write code once using HTML, CSS, and JavaScript, and then distribute it across Windows, Mac, and Linux operating systems. This eliminates the need to build platform-specific apps and maintains a single codebase.

Leverage Web Technologies

Since Electron uses Chromium and Node.js under the hood, developers can build apps using familiar web languages and frameworks like HTML, CSS, JavaScript, and Node. This allows web developers to easily transfer their skills to build desktop apps.

Large Ecosystem of Modules

There is a huge ecosystem of Node.js modules that can be leveraged in Electron apps to add functionality. This includes modules for UI frameworks like React and Angular, as well as modules for accessing native features like the file system and notifications. Developers can tap into this ecosystem to accelerate app development.

Active Community

Electron has an active open-source community behind it, with major tech companies like Microsoft, Slack, and GitHub contributing. This provides helpful resources and support for developers building Electron apps.

Use Cases

Electron has become a popular framework for building cross-platform desktop applications using web technologies. Some of the most well-known Electron apps include:

Communication Apps

• Slack – The popular team communication app leverages Electron Dash to create desktop apps for Windows, Mac, and Linux. Electron allows Slack to use familiar web technologies for the UI while accessing native OS features like notifications and system dialogs.

• Skype – Skype uses Electron to build the desktop version of their communication app. Electron’s cross-platform abilities allow them to maintain one codebase while releasing on major desktop platforms.

• WhatsApp – The desktop version of WhatsApp is built on Electron. This allows web developers at WhatsApp to reuse their web app code while having access to OS APIs.

Developer Tools

• Visual Studio Code – Microsoft’s lightweight and popular code editor is built with Electron. It provides users a familiar interface and features, while VS Code developers can leverage web technologies.

• GitHub Desktop – GitHub’s desktop Git client uses Electron for cross-platform capabilities and web technologies. The Electron architecture has enabled fast iteration for new features.

• WordPress Desktop – Automattic leveraged Electron to create a native desktop app for managing WordPress blogs and websites. It provides a native app experience while using existing skills and code from the WordPress web app.

Overall, Electron has proven to be a popular choice for creating desktop apps across communication, productivity, and developer tools. Its cross-platform abilities and mix of web and native features make it compelling for many use cases.

Basic App Structure

The basic structure of an Electron app consists of a few key files and components:

Main Entry Point File

This is usually a file named main.js or index.js that serves as the entry point for the app. It runs in the main process and controls creating windows, interacting with native APIs, etc.

package.json

This contains metadata for the app like name, version, dependencies, etc. It’s similar to a Node.js app.

index.html

This is the html file that will be loaded in the renderer process to display the UI. The renderer process displays web pages and interacts with the DOM.

Renderer and Main Processes

Electron Dash apps have two types of processes – the main process that runs main.js and controls the lifecycle, and renderer processes that display web pages and handle UI. The main and renderer processes can communicate with each other using IPC.

Some key differences are:

• The main process has access to Node.js APIs and native modules while the renderer process can only use web-related APIs.

• Code running in the renderer process is sandboxed for security while the main process has full access to the system.

So in summary, the main process manages app lifecycle events and system access while renderer processes display UI and render web pages. These two process types allow Electron apps to mix native OS capabilities with web technologies.

Accessing Native Features

Electron Dash allows developers to access native features of the operating system through Node.js APIs and native UI features through Chrome APIs. This enables building desktop applications with web technologies that can leverage capabilities beyond what web apps can normally access.

For example, Electron Dash exposes Node.js modules for file system access, allowing developers to read and write files on the user’s system. Common modules used include fs for file system access, path for file path operations, and os for operating system information. By leveraging these modules, Electron Dash apps can create, edit, and delete local files and directories.

Electron also provides browser window APIs from Chromium for building native-like UI components. This includes support for menus, notifications, dialog boxes, and more. Developers can use web technologies like HTML, CSS, and JavaScript to construct the UI and then access Chromium APIs to make it feel more native. For example, you can use the BrowserWindow and Menu APIs to create app windows with customized menus.

The combination of Node.js and Chromium APIs gives developers a powerful platform for building desktop apps. Electron removes the restrictions of the web sandbox and allows accessing OS-level functionality in a way not possible with regular web apps. At the same time, it leverages web technologies that many developers are already familiar with.

Distribution

Electron apps can be distributed in a few different ways. The most common approaches are packaging the app and publishing to app stores.

Packaging

To package an Electron app for distribution, a module like electron-builder is commonly used. It handles tasks like generating installers and auto-update frameworks for different operating systems.

With Electron Dash-builder, you can generate packages for Linux, Windows, and macOS. It has options to configure auto-updating using Squirrel (Windows) and electron-updater (macOS and Linux). This allows you to easily push updates to your users.

App Stores

Once your Electron app is packaged, it can be published to app stores like the Mac App Store, Microsoft Store, Snapcraft Store or AppImageHub. This gives your app more visibility and makes it easy for users to install.

The major app stores have specific requirements around code signing and metadata that must be met. But overall the process is straightforward with tools like Electron Dash-builder handling much of the heavy lifting.

Publishing to app stores brings additional credibility and trust for users. It also opens up new monetization options if you charge for your app. The wide distribution makes Electron a great framework for both open-source and commercial apps aiming to reach a large audience.

Performance Considerations

When building Electron apps, performance optimization is crucial for providing a smooth user experience. Electron apps have higher resource usage compared to native applications since they bundle Chromium and Node.js. Here are some techniques to optimize performance:

Manage Memory Usage

• Limit the number of main processes. Each main process runs its own V8 instance, so minimizing main processes reduces memory overhead. Use BrowserWindows sparingly and close unused windows.

• Enable Chromium’s partition option to run code in a separate context and prevent leaks between web pages.

• Use offscreen-rendering to reduce GPU memory in invisible BrowserWindows.

• Unload JavaScript contexts when windows are closed with webContents.destroy().

• Use webFrame.clearCache() to purge resources from the in-memory cache.

Optimize CPU Load

• Debounce rapid-fire events like scroll and input to limit event handling.

• Use Web Workers for long computations to prevent blocking the UI thread.

• Profile CPU usage with Chrome DevTools to identify hot paths for optimization.

• Cache data instead of recomputing. Use ipcMain and ipcRenderer for communication.

• Load resources on demand and lazily instantiate objects.

Other Tips

• Use native modules for performance-critical code.

• Compress assets to reduce bundle size.

• Throttle events during application startup.

• Show loading indicators for long operations.

With awareness around performance, Electron apps can stay fast and responsive across platforms. Careful coding and profiling helps prevent jank and lag in the app.
