What Hacker News says?
Actually, React's problem is that it's the inverse of how HTML and JavaScript works in terms of how to handle callbacks. Of the major UI frameworks, it is the only one with this quality (Vue, Svelte, Angular, Solid, etc. use signals). This inverted behavior is the cause of most of the pain and footguns in React and React Hooks because the way state behaves in a React component is not the way state behaves in any oth…

HN discussionIt was more of a general misunderstanding on how React Query is supposed to work, partially triggered by some mistakes in defining the query keys that meant that React Query didn't work as intended. I'd recommend this blog post (or actually all blog posts on React query on that site): https://tkdodo.eu/blog/effective-react-query-keys What I observed was that the query keys were not consistently defined, which broke…
