React Summit US

React Summit US 2023

This talk discusses the best practices for fetching data during the initial render of a component in React. It emphasizes the importance of fetching in advance and avoiding fetching twice. The talk also highlights the need for an external cache to store information about API calls and the use of a cleanup function to avoid memory leaks. Additionally, the speaker mentions their library, react-disposable-state, which can be used for making side effects during render.

What is suspense for data fetching in React? Why does React's model make creating network requests during render so difficult? Why does (to the presenter's knowledge) no library besides Relay support this, despite its sheer convenience?
 In this talk, Robert will discuss how React renders components (especially with regards to Suspense), and how to build a data-fetching library that functions correctly in light of those behaviors. Then, with all the pieces in place, we'll use a library, @boulton/react-disposable-state, to roll our own suspense-compatible data fetching!
