What Is ElectronJS? ⚛️
The key idea behind ElectronJS is to combine web technologies with a lightweight runtime environment to create desktop applications that can run on multiple operating systems, such as Windows, macOS, and Linux. This is achieved by bundling a web rendering engine (Chromium) with Node.js, which provides access to native operating system features.
Advantages Of ElectronJS For Cross-Platform Development 🎯
🤹 Simplicity & Versatility
ElectronJS simplifies the development process by providing a single codebase for multiple platforms. Developers can utilise their existing web development skills and tools, making it easier to transition into desktop application development. This improved sense of versatility compared to other similar frameworks helps developers by saving their time and effort by eliminating the need to learn platform-specific languages or frameworks.
🌐 Access To Web Technologies
🦄 Unique Architecture
👨👨👦👦 Community & Ecosystem
One of ElectronJS’s greatest strengths is its vibrant community and ecosystem. Developers can tap into a vast library of plugins, frameworks, and tools created by the community to extend the functionality of their applications. From UI frameworks like React and Vue.js to specialised libraries for file handling or database integration, the ElectronJS ecosystem provides the necessary resources to enhance productivity and build robust applications.
Limitations & Considerations For The Electron Framework 🚧
While ElectronJS offers numerous advantages, it’s important to consider a few limitations.
💾 Memory Usage
ElectronJS applications may consume more memory compared to native applications due to the bundled Chromium runtime. That said, careful optimisation and efficient resource management can help mitigate this issue. Electron.js applications have a higher memory footprint compared to native applications. This is because Electron bundles a full Chromium browser along with the application code. As a result, Electron apps may consume more system resources, which can be a concern for low-end devices or memory-constrained environments.
⚖️ Application Size
ElectronJS applications tend to have larger file sizes compared to their native counterparts. This is because ElectronJS packages the runtime alongside the application. But again, there is a fix, employing compression techniques and minimising dependencies can help reduce the application size.
⏫ Distribution Size
Electron.js applications tend to have larger distribution sizes compared to native applications. This is because Electron packages the entire runtime environment, including Chromium, into the final executable. It can result in larger installation files and longer download times, which may be inconvenient for users with limited bandwidth or storage space.
⛔ Lack Of Native UI Components
Electron.js relies on web technologies to create user interfaces, which can sometimes result in a less native look and feel. Although there are libraries like Photon, Spectron, and React Native for Electron that provides native-like UI components, achieving a fully native experience may require additional effort and customisation.
🦻 Built-In Accessibility Features
ElectronJS does not provide built-in support for platform-specific accessibility features. While it is possible to implement accessibility features manually, it requires extra effort from developers to ensure that Electron apps are accessible to users with disabilities. Native frameworks often have better integration with platform accessibility APIs.
Electron.js applications inherit the security vulnerabilities of the underlying Chromium browser. Keeping Electron applications updated with the latest Chromium version is crucial to mitigate potential security risks. Additionally, the use of web technologies may introduce additional attack vectors that developers need to be aware of and handle appropriately.
Should You Use ElectronJS For Cross-Platform Software Development? 🕵️
When evaluating Electron’s performance, it’s important to consider the practical challenges and constraints faced by real-world web development teams, which are often overlooked in purely performance-oriented critiques. Targeting multiple platforms, such as Windows, Linux, and macOS, while simultaneously maintaining a web app can be prohibitively expensive. It requires the creation and management of four separate codebases, significantly increasing costs and complexity.
Furthermore, the operational aspects of adopting native development should be taken into account. If your development team and existing technology stack are primarily focused on web technologies, delving into native development can pose significant challenges. It may necessitate a complete reevaluation of your development approach and require acquiring new skills and knowledge.
Hiring the right talent can be a major hurdle. Developers specialising in specific technology stacks are proficient at identifying and recruiting like-minded professionals. However, they may lack the expertise to assess competency in different domains. Suddenly, your organisation is now faced with the task of not only mastering one new domain but multiple ones simultaneously. This can be overwhelming and a potential deal breaker for many products.
Electron offers a solution to mitigate these complexities. Most businesses, regardless of their size, already have a web development team in place, whether in-house or through agencies. By leveraging Electron, they can continue using familiar web technologies and pipelines to build new applications, all within a shared codebase. Scaling the team becomes more manageable, requiring fewer additional hires, and recruitment can be based on technologies already utilised.
These practical business considerations make Electron an attractive choice. It presents a classic 80/20 scenario, where you can achieve 80% of the functionality and performance of a native app at just 20% of the cost. For most, this tradeoff is highly appealing. In many cases, the decision lies between developing an Electron app or forgoing a desktop app altogether, as building natively may not be a feasible option.
Best Practices For ElectronJS Development 🏆
To maximise the potential of ElectronJS, we recommend considering the following best practices.
🎭 Performance Optimisation
Employ techniques like lazy loading, efficient rendering, and memory management to enhance the performance of your ElectronJS application. Due to the overhead of running a full browser instance, Electron.js applications may not perform as well as native applications, especially for computationally intensive tasks. But keep in mind that while Electron has made significant performance improvements over the years, it may still lag behind native solutions in certain scenarios.
📊 Memory Management
Electron.js applications can consume a significant amount of memory. Be mindful of memory usage and avoid memory leaks. Properly release resources, unsubscribe event listeners, and dispose of objects when they are no longer needed.
⭐ Native-Like User Experience
Strive to provide a native-like user experience to enhance usability and familiarity. Use platform-specific UI components and design patterns to match the user’s expectations. Consider using libraries like Photon, Spectron, or React Native for Electron to access native UI elements.
🚚 Packaging & Distribution
Consider the size and distribution of your Electron application. Minimise the package size by excluding unnecessary files and optimising assets. Use compression techniques and package formats that reduce download sizes. You should also consider delta updates or differential packaging to minimise bandwidth usage during updates.
🧪 Cross-Platform Testing
Test your Electron application on different platforms and configurations to ensure compatibility and consistent behaviour. Pay special attention to platform-specific nuances, such as file system differences, system font rendering, and UI scaling. And finally, use automated testing tools and frameworks to streamline the testing process.
🔐 Security Considerations
Developers need to be mindful of employing the best security best practices when developing Electron applications due to the inherent vulnerability that is common amongst platforms relying on basic web development technologies. Make sure to regularly update Electron to benefit from security patches and bug fixes. Also, Implement secure communication protocols, validate user inputs, and apply appropriate security measures to protect against common web vulnerabilities.
♿ Never Ignore Accessibility
Ensure that your Electron application is accessible to users with disabilities. Follow accessibility guidelines, provide alternative text for images, use semantic HTML, and test your application with screen readers and assistive technologies. You can also look into leveraging platform-specific accessibility APIs to enhance accessibility features.
🚨 Error Handling & Logging
Implement robust error handling and logging mechanisms in your Electron application. Catch and handle errors gracefully to prevent crashes and provide meaningful error messages to users. Log errors and exceptions to facilitate troubleshooting and debugging.
🛠️ Continuous Integration & Deployment
Set up a continuous integration (CI) and deployment pipeline to automate the build, QA testing, and deployment processes. CI/CD tools like Jenkins, Travis CI, or GitHub Actions can help streamline the development workflow and ensure consistent and reliable releases across different platforms.
