The Evolution of React Native and Expo
- React Native 0.74 (December 2023) officially endorsed Expo as the primary project initiation method.
- In the docs, you'll find the statement 'You can also use React Native without a Framework, however we’ve found that most developers benefit from using a React Native Framework like Expo.'
- Prior to 0.74, React Native promoted a bare CLI workflow alongside Expo.
- Expo's rise reflects its maturity and readiness for professional development workflows.
- Official docs now funnel newcomers directly into Expo’s managed or bare workflow ecosystem.
The Challenges of the Bare React Native CLI
- Bare CLI setup involved complicated processes (Homebrew, Xcode, various CLI tools).
- Debugging was frequently frustrating, requiring unfamiliar terminal commands.
- Frequent Xcode rebuilds and dealing with 'Derived Data' clutter was commonplace.
- These extra steps and processes regularly distracted from app development itself.
Expo’s Streamlined Development Experience
- Expo eliminates complex native environment setups with the intuitive Expo Go app.
- Provides clear and informative runtime error messages, enhancing debugging ease.
- Expo CLI simplifies package management (add/remove/update without constant Xcode rebuilds).
- Expo documentation is detailed, beginner-friendly, and reliably up-to-date.
Simplified Access to Native Features
- Expo includes built-in modules for essential native features like camera, GPS, notifications, and payments.
- Native modules provided by Expo work seamlessly across iOS and Android.
- Expo modules significantly reduce setup complexity compared to third-party npm packages.
- Built-in modules minimize painful native dependency conflicts and configuration errors.
Embracing the New Architecture
- Expo SDK (from SDK 53 onward) supports React Native’s 'New Architecture.'
- The New Architecture includes bridgeless implementations for faster app performance.
- Expo's quick adoption demonstrates a commitment to future-proofing your projects.
- By leveraging Expo, developers stay aligned with React Native’s cutting-edge developments.
Conclusion
- Bare React Native CLI offers flexibility but at the expense of complexity.
- Expo delivers the ideal balance: simplified workflows, clarity, and power.
- Expo’s built-in tools and modules accelerate development and improve consistency.
- If you prioritize productivity, clear documentation, and stress-free app development, Expo is the ideal choice.
