I'm working on a React application that needs to display a large list of items (thousands of rows). Currently, the performance is quite slow when the user is scrolling through the list or filtering the items. What are some ways that I can optimize the performance of my React application to improve the user experience?
Some additional information:
-I'm using React functional components and hooks to render the list of items. -Each item in the list contains several fields of data, including text and images.
-I'm currently using the built-in map function to render the list of items.
-I'm using a library to handle filtering and sorting the list of items.
-I've already tried implementing shouldComponentUpdate and React.memo to improve performance, but it's still not fast enough.
I'm open to any suggestions, including using third-party libraries or rewriting parts of the application if necessary. Thanks in advance for your help!
You could use the library react-window. It's useful to virtualize the scroll in a large list of elements and should help you in performance tuning.
