What Causes Performance Bottlenecks In Large React Apps? Are you struggling to identify why your large React application feels sluggish or unresponsive? In this detailed video, we'll explore the main reasons behind performance bottlenecks in big React apps. We'll start by explaining how React updates the user interface and why certain patterns can cause delays. You'll learn how unnecessary re-renders happen and how to prevent them using React’s memoization tools like React.memo and shouldComponentUpdate. We’ll also cover common issues with inefficient state management, such as lifting state improperly or overusing context, and how centralized solutions like Redux or Zustand can help. Additionally, we’ll discuss the impact of large JavaScript bundles and how code-splitting with tools like Webpack and React lazy loading can improve load times. You’ll discover strategies to reduce network requests, optimize data fetching, and implement server-side rendering or static site generation for faster initial loads. We’ll also highlight the importance of managing event listeners and third-party libraries to avoid memory leaks and CPU hogging. Lastly, you’ll see how inline functions and styles can cause extra re-renders, and how to prevent this with better coding practices. By following these tips and regularly profiling your app, you can keep your React projects running smoothly and provide a better experience for your users.
