3. Comparison with Native and Cross-Platform Options

React Native presents a middle ground between native app development (which requires separate codebases for iOS and Android) and other cross-platform tools (which might not offer native-level performance).

It allows developers to write one codebase that works across platforms, reducing time-to-market while still providing near-native performance.

• Performance: React Native’s use of native components makes it more efficient than traditional hybrid frameworks like Cordova or PhoneGap.
• Native Code Flexibility: Unlike other frameworks, React Native allows easy linking to native code, making it a suitable choice for performance-intensive apps.

Note: React Native is especially effective for projects with fast timelines and smaller budgets, while apps requiring heavy native integrations might still benefit from native development.

Now that we’ve established React Native’s benefits, let’s look at the different approaches you can take when developing apps, and how to choose the best one based on your project needs

React Native Development: Key Approaches for Building High-Performance Apps

When building a React Native app, developers have several approaches at their disposal, each with its own set of advantages and limitations.
