React Native Performance Optimization and Profiling

#reactnative Performance Optimization and Profiling

  • State of React Native performanceReact per default re-renders a component every time its parent receives new props or updates its state, that’s one of many reasons why the React paradigm for building UI’s is superior.
  • Luckily many of the standard React Native components executes on a separate thread known as the main thread.
  • If you are offloading work from JavaScript to the native side prevent the bridge from becoming overloaded by monitoring how many times data are sent and received over the wire.
  • class Component extends React.Component { – renderSectionHeader = () = View style={…} /render() { – return ( – FlatList – {…this.props} – / – ) – } – }If you still consider to handle navigation on the JavaScript side or you are struggling with frame drops during animations.
  • class AfterInteractions extends React.Component {state = { interactions: true } – – componentDidMount() { – = { – this.setState({ interactions: false }) – }render() { – if (interactions) { – return null – } – return this.props.children – } – }Animations in React Native looks good and are easy to…

React Native is a popular technology for engineers who are looking for building mobile applications in a productive way without compromising on native performance. Devices today comes with multi core…

Using Native SDKs and Libraries in React Native

Using native SDKs and libraries with #React Native

  • Most of the time, these are only available in their native version, and only accessible as Objective-C or Swift libraries in the case of iOS apps or as Java Classes for Android apps.
  • Step 2: Call our bridge from our React Native code.
  • Step 1: Create two native files for our bridge.
  • An Objective-C class is made out of two files, a .m and a .h, holding the module implementation and the header for this module respectively.
  • When building an app in React Native we may end up needing to use third-party SDKs or libraries.
