Mo Khazali, Head of Mobile and Tech Lead at Theodo UK, dives into Universal React, highlighting its power in cross-platform development. He reveals how this framework allows small teams to harness a single codebase for both web and mobile apps. Mo discusses the evolution of code sharing, the significance of the Fabric Rendering Layer in React Native, and the shift towards customizable component libraries. He also emphasizes how Universal React empowers smaller developers to compete with the giants in tech.
Universal React streamlines cross-platform development by allowing sharing of code between web and mobile without sacrificing native quality.
The framework empowers smaller teams to innovate quickly and compete with larger companies by minimizing resource use and codebase management.
Deep dives
Understanding Universal React
Universal React aims to optimize code sharing between web and mobile platforms while ensuring the native experience is maintained across all devices. By utilizing a shared codebase for React and React Native, developers can write UI definitions once and deploy them on different platforms, thus improving efficiency. The concept is built on the notion that user interfaces can be consistent regardless of the device type, while also allowing for platform-specific enhancements to avoid sacrificing quality. Ultimately, Universal React is about maximizing the potential of shared code without compromising the native experience users expect.
Challenges and Opportunities in Cross-Platform Development
The fragmented landscape of multiple operating systems and device types presents significant challenges for developers seeking to create universal applications. Historical attempts at creating cross-platform solutions, like Java and Flash, often resulted in subpar experiences due to their disregard for platform-specific implementations. In contrast, Universal React respects the unique elements of each platform by ensuring that the right renderer is utilized, like React DOM for web and native views for mobile. As new technologies emerge, such as AR and IoT devices, the need for robust cross-platform solutions becomes even more critical.
Empowering Smaller Teams with Universal React
Universal React provides a distinct advantage for smaller teams and indie developers by enabling them to build applications for multiple platforms without the need for extensive resources. For instance, Blue Sky, a social media platform, managed to launch its app for iOS, Android, and web with a small team by leveraging Universal React. This approach allows these teams to focus on product development rather than juggling multiple codebases, ultimately leading to faster iterations and more innovative features. As a result, independent developers can compete more effectively with larger tech companies.
Performance Considerations for Universal Apps
To ensure optimal performance in universal applications, developers must understand the distinct requirements and considerations for web and native platforms. Native performance relies on efficient CPU and RAM usage, while web performance is often tied to factors like SEO and loading times. Making informed decisions about component choices and implementation strategies, such as selecting appropriate list components for web, can greatly affect the user experience. By also optimizing the bundler setup and utilizing tools like Expo and Next.js, developers can achieve a smooth performance across different devices.
