When building React Native applications, developers are often faced with a critical decision: use the streamlined, managed workflow provided by Expo, or opt for the flexibility of a custom React Native architecture. Both options have their merits, but in my experience, Expo architecture consistently provides an edge for many development scenarios.
Here’s why I prefer Expo and how it simplifies and accelerates the app development process.
1. Easy to Setup and Develop
With Expo, it’s as simple as running a few commands to get started. The managed workflow abstracts away many of the complexities involved in setting up a React Native project:
- Out-of-the-box tools: Expo provides pre-configured tools for development, including hot reloading, debugging, and performance monitoring.
- No native dependencies: Most of the time, you do not have to install Xcode or Android Studio to begin development, making it accessible for developers without native coding expertise.
In contrast, a custom React Native architecture often requires setting up native dependencies and configuring build environments manually, which can be very time-consuming and error-prone.
2. Rich Ecosystem and Pre-built Features
Expo provides a complete ecosystem of APIs and ready-to-use features such as the following:
- Camera, Location, Notifications, Sensors: Ready-to-use APIs for these common functionalities eliminate the need to install third-party libraries.
- Expo Go App: This allows you to preview your app in real-time on any device without building the project.
This often involves including third-party libraries for similar functionality in custom architecture, which may introduce some incompatibility and increase the maintenance overhead.
3. Faster Iteration and Development
Expo accelerates the development lifecycle with tools designed for rapid iteration:
- Over-the-Air (OTA) Updates: You can push updates directly to users without requiring them to download a new version from the app store.
- Expo Snack: A browser-based editor for quick prototyping and sharing React Native code snippets.
With custom architectures, developers have more control, but they do not have built-in features like OTA updates; for this, additional tools like CodePush are needed.
4. Cross-Platform Consistency
Expo’s managed workflow makes sure that your app behaves predictably on iOS and Android, handling platform-specific niceties internally so that you can focus on features instead of debugging differences between platforms.
Custom React Native architectures offer the most flexibility but require the most effort in maintaining cross-platform parity, especially when using native modules.
5. Less Complexity for Small to Medium Projects
The managed workflow from Expo strikes a great balance between simplicity and functionality for small to medium-sized apps. There’s no need to configure native modules or dig into platform-specific settings, which would often be overkill for such projects.
For very large enterprise-level applications that have very specific native requirements, this is where custom React Native architecture really shines. It brings a layer of complexity not necessarily needed by more lightweight applications.
6. Excellent documentation and community support
Expo boast some of the best documentation in the React Native ecosystem. The examples are clear, and it includes an API reference that is well-maintained. This means solutions to most issues can be found rather quickly because of an active Expo community.
While Custom React Native has equally robust documentation, native module integrations usually require piecing together several sources, which can’t help but slow down development.
7. When Custom React Native Architecture Wins
To be honest, there may be scenarios where that’s better fitting; for instance:
- Heavy Native Customizations: If your application needs to rely heavily on heavy native modules-custom advanced video editing, AR/VR then a custom architecture would give full control.
- Integration with Legacy Systems: Enterprise apps needing specific integrations may be better off with a custom setup.
- Unique Performance Needs: Custom architecture permits tuning for peak performance in resource-intensive applications.
However, for the majority of applications, especially those targeting rapid development and deployment, Expo’s architecture is a clear winner.
Conclusion: A Developer-Friendly Choice
The choice between Expo and a custom React Native architecture will always depend on your project’s needs. But for developers who value ease of use, rapid iteration, and a rich ecosystem of features, the managed workflow is a game-changer offered by Expo.
By abstracting the development process and decreasing the need to involve native expertise, Expo enables developers to pay more attention to building amazing user experiences; hence, it is my go-to choice for most React Native projects.
