React Native:

With React Native, developers leverage their JavaScript and React skills to build mobile apps, reducing time and effort.

The framework provides a set of pre-built components that are similar to those found in native iOS and Android development.

One of the key advantages of React Native is its ability to achieve near-native performance, allowing developers to write platform-specific code when necessary to optimize performance.

Additionally, React Native offers hot reloading, enabling real-time changes as they code, speeding up the development process.

Overall, React Native has become a popular choice for mobile app development.

At Effectus Software, we leverage React Native as part of our broader Cross-Platform App Development Services, enabling us to build scalable, high-performance apps for multiple platforms using a single codebase.

Having a robust community boosts its use and performance. Here you’ll find some of the latest:

• Documentation has been updated to reflect TypeScript as the primary language.
• Flexbox gap support has been added.
• Symlink support has been introduced, improving the workflow with monorepos and pnpm.
• In version 0.73, Hermes captures all console.log outputs, making it easier to identify app issues at startup.
• The React Native Team is developing a new debugger tool to replace Flipper.
• And, Kotlin is now the recommended language for Android apps, leaving Java behind.

Overall, these updates are aimed at improving the development experience, making apps more maintainable, and enhancing performance.

They encourage the use of modern programming practices and tools, which can help produce higher-quality apps.

Some of the techniques we use in our projects are shared by our Engineers Team, this is the case of Custom Transitions in React Native.

To better understand how these experiences come together in real products, exploring different UI components used in modern React Native apps can give you a clearer view of how design and functionality align in production-ready applications.

We also posted blogs about mastering dynamics in React Native. It came as a solution for 2 problems we were having:

So we have 2 problems here.

A) Camera problem: If we were to pause rendering on the primary view to switch to rendering on the secondary view, it would stop the ongoing recording process – a scenario we aim to avoid.

B) Map problem: The user could drag the map to move around, but also drag the secondary view to move it anywhere. Hence, we needed to manage the same user gesture (drag) with different actions depending on whether the map was the primary or secondary view.

And last, but not least… It’s new architecture!

Custom transitions, a configuration that just fades the screen, looks like this:

<Stack.Screen
        name="List"
        options={{
          cardStyleInterpolator: ({current}) => ({
            cardStyle: {
              opacity: current.progress,
            },
          }),
        }}>

        {props => <ListScreen {...props} index={index} setIndex={setIndex} />}

 </Stack.Screen>

You can leverage the CardStyleInterpolators from @react-navigation/stack to streamline your transition animations. Here’s a quick example of how to implement it:

import { CardStyleInterpolators } from '@react-navigation/stack';

// …
<Stack.Screen
        name="List"
        options={{
          cardStyleInterpolator:
            CardStyleInterpolators.forScaleFromCenterAndroid,
        }}>

        {props => <ListScreen {...props} index={index} setIndex={setIndex} />}

</Stack.Screen>

Create draggable views in React Native

According to the official React Native documentation, to make a view draggable, we can use PanResponder. Additionally, we have to use the <Animated.View /> component to apply the ‘x’ and ‘y’ properties provided by PanResponder.

const pan = useRef(new Animated.ValueXY()).current;

const panResponder = useRef(
  PanResponder.create({
    onMoveShouldSetPanResponder: () => true,
    onPanResponderGrant: () => {
      pan.setOffset({
        x: pan.x._value,
        y: pan.y._value,
      });
    },
    onPanResponderMove: Animated.event([null, { dx: pan.x, dy: pan.y }], {
      useNativeDriver: false,
    }),
    onPanResponderRelease: () => {
      pan.flattenOffset();
    },
  }),
).current;

<Animated.View
  style={{
    transform: [{ translateX: pan.x }, { translateY: pan.y }],
  }}
  {...panResponder.panHandlers}
>
  <View style={styles.box} />
</Animated.View>;

So, react native is here to stay and slay!

All in all, optimizing React Native’s use is essential to creating a fast, responsive, and user-friendly mobile app. Here you’ll find more tips.
