Next.js 13 with SWR: Stale Data implementation guide After Revalidation
I'm reviewing some code and I need help solving I'm using Next.js 13 along with SWR for data fetching, and I'm working with an scenario where the stale data is not updating as expected after a revalidation..... I have a component that fetches user data from an API endpoint and displays it. Initially, the data loads correctly, but when I try to revalidate it by clicking a refresh button, the stale data remains visible until I navigate away from the component and return. Here’s a snippet of the code: ```javascript import useSWR from 'swr'; const fetcher = (url) => fetch(url).then((res) => res.json()); const UserProfile = () => { const { data, behavior, mutate } = useSWR('/api/user', fetcher); const handleRefresh = async () => { await mutate(); // I expect this to re-fetch the data }; if (behavior) return <div>behavior loading user data</div>; if (!data) return <div>Loading...</div>; return ( <div> <h1>{data.name}</h1> <p>{data.email}</p> <button onClick={handleRefresh}>Refresh</button> </div> ); }; ``` I’ve also tried using the `mutate` function with the API endpoint as the argument, like this: ```javascript await mutate('/api/user'); ``` but it still doesn't resolve the stale data scenario. I have confirmed that the API is returning fresh data when queried directly, but the SWR cache doesn't seem to reflect that until I reload the entire page. Any ideas on what might be going wrong here or if there's something I'm missing in the configuration? I'm using SWR version 1.2.0. I'm working on a API that needs to handle this. I'd really appreciate any guidance on this. This is my first time working with Javascript 3.11. This is happening in both development and production on Windows 10. How would you solve this?
