Usefetch doesnt work when using middleware

Hi, I have a problem. If I use middleware (even if it is empty), my usefetch does not work during ssr. It does get the data, but it doesn't pass it to the client.

Hi @Rush. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- This issue you're experiencing with useFetch not working properly when using middleware in Nuxt is a known problem that has been reported and discussed in the Nuxt community. The root cause appears to be related to how the request context and headers are handled during server-side rendering (SSR) when middleware is involved. To address this issue, you can try the following solution: 1. Use useRequestFetch instead of useFetch in your component or page where you're fetching data. This composable is designed to forward the request context and headers properly during SSR. Here's an example of how you can modify your code:

<script setup>
const requestFetch = useRequestFetch()
const { data } = await useAsyncData(() => requestFetch('/your-api-endpoint'))
</script>

<script setup>
const requestFetch = useRequestFetch()
const { data } = await useAsyncData(() => requestFetch('/your-api-endpoint'))
</script>

This approach is recommended in the Nuxt documentation on useRequestFetch (https://nuxt.com/docs/api/composables/use-request-fetch), which states: "You can use useRequestFetch to forward the request context and headers when making server-side fetch requests." The useRequestFetch composable ensures that the necessary headers and context are properly forwarded during SSR, which should resolve the issue of data not being passed to the client when middleware is used. If you're still experiencing issues after trying this approach, it might be worth checking if there are any specific interactions between your middleware and the fetch requests. You may need to ensure that your middleware is not interfering with the request context in any way. Nuxt GitHub Issue #27902 (https://github.com/nuxt/nuxt/pull/27902) also discusses a related fix for useFetch with customized $fetch losing the original event during SSR, which might be relevant to your situation. Remember to test thoroughly after making these changes to ensure that your data fetching works correctly both during SSR and client-side navigation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
