$fetch sends a HTTP request from both client and server?

Can someone help me disable the duplicate requests $fetch is sending from my server? Ex if someone presses a button to trigger an api call, it will send a request from my servers’s ip and another from my client ip. This is causing my api to do double the work for no reason. I don’t want to have to disable SSR.

Hi @23brewert. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the knowledge sources provided, I can help clarify the behavior of $fetch in Nuxt and suggest a solution to your problem. You're correct that using $fetch directly can lead to duplicate requests being sent from both the server and client sides. This is because $fetch doesn't have a built-in mechanism to prevent double data fetching during server-side rendering and client-side hydration. To avoid this issue and prevent unnecessary API calls, Nuxt recommends using either useFetch or useAsyncData + $fetch instead of $fetch alone for data fetching in components. These composables are designed to handle the server-to-client state transfer, ensuring that data is fetched only once. Here's how you can modify your code to prevent duplicate requests: 1. For component data fetching, use useFetch: 
const { data } = await useFetch('/api/endpoint')
const { data } = await useFetch('/api/endpoint')
2. For user interactions (like button clicks), you can continue using $fetch directly since these actions typically occur only on the client side: 
async function handleButtonClick() {
  const response = await $fetch('/api/endpoint', {
    method: 'POST',
    body: { /* your data */ }
  })
}
async function handleButtonClick() {
  const response = await $fetch('/api/endpoint', {
    method: 'POST',
    body: { /* your data */ }
  })
}
By using useFetch for initial data fetching and $fetch for client-side interactions, you can avoid duplicate requests without disabling SSR. For more detailed information on this topic, you can refer to the following sources: - Nuxt Data Fetching (https://nuxt.com/docs/getting-started/data-fetching#the-need-for-usefetch-and-useasyncdata) - Nuxt $fetch Documentation (https://nuxt.com/docs/api/utils/dollarfetch) These changes should help you optimize your API calls and prevent unnecessary server load. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Please provide some code example. $fetch wouldn’t make a request server side if based on an action on the client side, unless it’s incorrectly implemented.
