Stop using UseEffect for data fetching

UseEffect hook is a good choice for fetching data in small apps. However, for larger, more complex applications, it has several limitations.

๐—Ÿ๐—ถ๐—บ๐—ถ๐˜๐—ฎ๐˜๐—ถ๐—ผ๐—ป๐˜€ ๐—ผ๐—ณ ๐˜‚๐˜€๐—ฒ๐—˜๐—ณ๐—ณ๐—ฒ๐—ฐ๐˜ ๐—ณ๐—ผ๐—ฟ ๐—ฑ๐—ฎ๐˜๐—ฎ ๐—ณ๐—ฒ๐˜๐—ฐ๐—ต๐—ถ๐—ป๐—ด:

  • ๐—ก๐—ผ ๐—ฐ๐—ฎ๐—ฐ๐—ต๐—ถ๐—ป๐—ด: Fetches data after every component mount.

  • ๐—Ÿ๐—ผ๐—ฎ๐—ฑ๐—ถ๐—ป๐—ด ๐˜€๐˜๐—ฎ๐˜๐—ฒ needs to be tracked manually.

  • No built-in error handling.

As a result of the above limitations, you often write a lot of repetitive code to handle loading states, errors, and data management.

๐—ช๐—ต๐—ฎ๐˜'๐˜€ ๐˜๐—ต๐—ฒ ๐—ฎ๐—น๐˜๐—ฒ๐—ฟ๐—ป๐—ฎ๐˜๐—ถ๐˜ƒ๐—ฒ?

Use data-fetching libraries like ๐—ฅ๐—ฒ๐—ฎ๐—ฐ๐˜ ๐—ค๐˜‚๐—ฒ๐—ฟ๐˜†.

๐—ž๐—ฒ๐˜† ๐—ณ๐—ฒ๐—ฎ๐˜๐˜‚๐—ฟ๐—ฒ๐˜€ ๐—ผ๐—ณ ๐—ฅ๐—ฒ๐—ฎ๐—ฐ๐˜ ๐—ค๐˜‚๐—ฒ๐—ฟ๐˜†:

  • Access and manipulate fetched data from anywhere in your app.

  • Built-in caching: Fetched data are cached and reused.

  • Automatic loading state management.

  • Built-in error handling.

  • Support for pagination and infinite scroll.

  • Data prefetching.

Conclusion

By using data fetching libraries like React Query, you can significantly reduce boilerplate and improve the efficiency of data fetching in your React applications.
