Hi @old garden. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To proxy API requests in Nuxt 3 when using useFetch, you have a few options. Here are the recommended approaches:

1. Use Nitro's devProxy configuration:

This is a simple way to set up proxying for development:

// nuxt.config.ts
export default defineNuxtConfig({
  nitro: {
    devProxy: {
      '/api': '<http://your-api-server.com'>
    }
  }
})

2. Create a Nitro proxy API endpoint:

This method allows more control and works in both development and production:

// server/api/[...].ts
export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  const target = config.apiUrl // Set this in your runtime config
  
  // Remove /api prefix from the URL
  const url = event.node.req.url.replace(/^\/api/, '')
  
  // Proxy the request
  return await $fetch(url, {
    baseURL: target,
    headers: {
      // Forward headers as needed
    }
  })
})

3. Use a custom $fetch instance:

You can create a custom $fetch instance with a base URL and use it with useAsyncData:

// plugins/api.ts
export default defineNuxtPlugin(() => {
  const config = useRuntimeConfig()
  const api = $fetch.create({
    baseURL: config.apiUrl
  })

  return {
    provide: {
      api
    }
  }
})

// In your component
const { $api } = useNuxtApp()
const { data } = await useAsyncData('item', () => $api('/endpoint'))

These approaches are based on the information from Nuxt 3: The BEST way to proxy your API in Nuxt and Custom useFetch in Nuxt.

Remember to handle headers and cookies appropriately when proxying requests, especially for server-side rendering scenarios. The useRequestHeaders composable can be useful for this purpose.

Nuxt Documentation on Data Fetching provides more detailed information on using useFetch and other data fetching methods in Nuxt 3.
