🔁 Building Reusable Components: Best Practices

Creating reusable components is key to building scalable React Native apps. A well-structured component library ensures consistency and efficiency. Here’s how to do it right:

✅ Props-Driven Design: Pass styles, text, and actions via props instead of hardcoding.

✅ Use TypeScript: Define prop types for better maintainability and fewer runtime errors.

✅ Optimize Performance: Use React.memo to prevent unnecessary re-renders.

✅ Write Tests: Validate components using Jest & React Native Testing Library.

✅ Document Components: Tools like Storybook help visualize and test UI elements.

Building reusable components saves time and keeps your app organized.

React Native allows you to build native mobile apps using JavaScript and React. In this project-based course, learn how to use React Native to build production-ready, native mobile apps on both iOS and Android. To help acquaint you with the fundamentals of React Native, instructor Samer Buna takes a hands-on approach, showing how to build applications from scratch. He first walks through how to build a simple math game, and then demonstrates how to build a data-driven app. Along the way, he shows how to debug and solve common problems, and shares practical knowledge about testing and packaging your apps.

⚡️ Optimize Performance with `useCallback`

Using hooks incorrectly can lead to performance issues and memory leaks. One common mistake is redefining functions inside components, which causes unnecessary re-renders.

❌ Incorrect Usage

🔴 Functin recreated on every render, causing performance issues:

const renderItem = ({ item }) => (
handlePress(item.id)} />
);

✅ Optimized Usage with `useCallback`

✅ Memoizes function references to prevent unnecessary re-renders:

const renderItem = useCallback(({ item }) => (

), [handlePress]);

const handlePress = useCallback((id) => {
// operations
}, []);

Using useCallback ensures that renderItem remains the same across renders, significantly improving list performance in React Native apps. 🚀

Implementing Dark Mode Support 🌙

Dark mode is no longer just a trend—it’s an essential feature for accessibility and user comfort. Modern apps are expected to adapt to system preferences seamlessly.

🛠 Easy Implementation with React Native

Thanks to React Native’s useColorScheme(), your app can automatically switch themes:

import { NavigationContainer, DefaultTheme, DarkTheme } from '@react-navigation/native';
import { useColorScheme } from 'react-native';

function App() {
const scheme = useColorScheme();

return (

{/* Your app content */}

);
}

For manual theme toggling, use the Appearance API:

import { Appearance } from 'react-native';

// Toggle theme manually
Appearance.setColorScheme('dark');

Boost Your List Performance in React Native! ⚡️

Problem: Low scroll performance and frame drops in lists with large data sets (1000+ items)

✅ Solution:

- FlashList implementation instead of FlatList
- getItemLayout implementation
- ViewabilityConfig optimization
- Item render caching

🔥 Gains:

- Scroll FPS: Increased from 30fps to 58fps
- Initial render time reduced by 40%
- Memory usage decreased by 25%

import { FlashList } from "@shopify/flash-list";

const optimizedList = () => {
const getItemLayout = (data, index) => ({
length: ITEM_HEIGHT,
offset: ITEM_HEIGHT * index,
index,
});

return (

);
};

💡 Building a Better Mobile App for Your Startup

✔️ First and foremost, always prioritize the user experience. Understand the context in which your app will be used—whether users are on the move, multitasking, or in a specific environment.

✔️ Simplicity is key. Avoid overwhelming your users with too many features or cluttered interfaces.

✔️ Pay close attention to usability. Ensure that interactive elements are large enough for easy tapping, and provide clear visual cues for actions.

✔️ Test, test, and test again. Get your app into the hands of real users as early as possible. Observe how they interact with your app, and take note of any areas where they stumble or become confused.

✔️ Lastly, remember that design is an iterative process. Be open to making adjustments and refinements based on user feedback and usage data. A well-designed app is not just aesthetically pleasing but also highly functional, intuitive, and tailored to meet the needs of its users.

Storybook 8.3 for React Native!!

- Storybook is an open-source tool for building and showcasing UI components in isolation.
- It allows developers to create components independently of their app, making it easier to test, document, and share.
- By using a separate environment, you can preview each component’s behavior and appearance without relying on the entire app’s state.

Key benefits of the update:

- Robust Component Testing with Vitest integration.
- Consistent Visual Experience across platforms.
- Simplified Setup with streamlined Metro config.
- Enhanced Performance with a smaller bundle size.
