Suspense for Data Fetching: How to Fetch During Render

React Summit US

React Summit US 2023

Robert Balicki

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!
