Image Caching: What Is It?

When it comes to issues like images loading and re-rendering from remote destination, caching is an excellent solution. What image caching is all about is downloading an image to the app's cache directory or any other directory the app has access to and then loading it from local storage the next time the image loads.

Picture caching can be done in a number of different ways in React Native. There is a fantastic component known as React Native FastImage that takes care of all of your image caching without you having to write any additional code if you are developing a basic React Native application. If you're using Expo or working on a more complex project, you could even create your own image caching component from scratch.


FastImage is a library for React Native that helps improve the performance of image loading by using native libraries to decode and display images. Some benefits of using FastImage include:

  • Faster image loading: FastImage can significantly improve the performance of image loading in your React Native app by using native libraries to decode and display images.
  • Lower memory usage: FastImage uses less memory than the built-in Image component in React Native, which can help prevent your app from crashing due to memory constraints.
  • Better user experience: With faster image loading and lower memory usage, your users will experience a smoother and more responsive app.
  • Customizable: You can customize the loading and error images, and also you can use your own cache.
  • Easy to use: FastImage is easy to use and can be integrated into your React Native app with just a few lines of code.

Tips for Optimizing React Native Flatlist Performance

Tips for Optimizing React Native Flatlist Performance There are a few ways to  optimise  the performance of a FlatList in React Native: Utilize the prop initialNumToRender: You can set the number of items that should be displayed when the list loads for the first time with this prop. The list's initial load time can be speed up by setting this to a lower value. Make use of the prop onEndReachedThreshold: The distance at which the onEndReached callback will be triggered can be specified using this prop. You can improve performance and reduce the number of times the callback is called by setting this to a larger value. Utilize the prop keyExtractor: You can specify a unique keyExtractor for each item in the list with this prop. When items are added, removed, or rearranged, React can update the list more quickly by providing a keyExtractor. Make use of the prop removeClippedSubviews: If this prop is set to true, it will only render the items that are currently visi...
