server side internal redirect

Is it possible to internally redirect one server side api call to another?

Hi @bnason. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, it is possible to perform a server-side redirect from one API route to another in Nuxt. You can use the sendRedirect helper from h3 (which Nitro and Nuxt use under the hood) within your server API handler to send a redirect response to the client. This will instruct the client to make a new request to the target endpoint. Example:

// server/api/foo.get.ts
export default defineEventHandler(async (event) => {
  await sendRedirect(event, '/path/redirect/to', 302)
})

// server/api/foo.get.ts
export default defineEventHandler(async (event) => {
  await sendRedirect(event, '/path/redirect/to', 302)
})

This will send a 302 redirect to the client, causing the browser (or HTTP client) to request the new location. However, this is an external redirect from the server to the client, not an "internal" redirect where the server transparently proxies or forwards the request to another handler without the client being aware. If you want to "internally" call another API handler from within your handler (without redirecting the client), you can directly import and invoke the logic of the other handler, or use shared utilities. Nitro does not provide a built-in way to forward the event context to another route handler as an internal redirect, but you can structure your code to reuse logic as needed. For more details on server-side redirects, see the Advanced Usage section of the server directory docs. If you are looking for a true internal proxy (where the server handles the request to another route and returns the result without the client knowing), the knowledge sources do not explicitly mention a built-in method for this in Nuxt/Nitro. You would need to manually invoke the logic or use shared functions between handlers. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I really need a way to do a server side internal redirect because I am redirecting a post request. Maybe a way to pull the headers/body etc and just pass through a fetch request?

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, you can achieve a server-side "internal redirect" for a POST request in Nuxt by making a server-side fetch to the target endpoint from within your handler, forwarding the headers and body as needed. This approach allows you to proxy the request internally, so the client receives the response from the target endpoint without being aware of the redirection. How to do it: 1. Extract the request body and headers from the incoming event. 2. Use event.$fetch (available in server routes) to make an internal fetch to the target endpoint, forwarding the necessary headers and body. 3. Return the proxied response to the client. Example:

// server/api/redirect-proxy.post.ts
export default defineEventHandler(async (event) => {
  // Extract the body and headers from the incoming request
  const body = await readBody(event)
  const headers = getRequestHeaders(event)

  // Forward the request internally to another API endpoint
  const response = await event.$fetch('/api/target-endpoint', {
    method: 'POST',
    body,
    headers,
  })

  // Return the response from the target endpoint
  return response
})

// server/api/redirect-proxy.post.ts
export default defineEventHandler(async (event) => {
  // Extract the body and headers from the incoming request
  const body = await readBody(event)
  const headers = getRequestHeaders(event)

  // Forward the request internally to another API endpoint
  const response = await event.$fetch('/api/target-endpoint', {
    method: 'POST',
    body,
    headers,
  })

  // Return the response from the target endpoint
  return response
})

- event.$fetch will forward the request context and headers, except for headers that are not meant to be forwarded (like host, accept, etc.) see docs. - This approach works for POST and other HTTP methods, and the client will receive the response as if it came from the original endpoint. References: - Forwarding Context & Headers - useRequestFetch composable This is the recommended way to proxy or "internally redirect" server-side requests in Nuxt/Nitro. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the target endpoint still sees the original url path

kapa.ai•5w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- When you use event.$fetch or similar server-side internal fetch methods in Nuxt, the target endpoint will see the request as coming from the new internal fetch, not as the original incoming request. This means the target endpoint will see the URL path you specify in the internal fetch (e.g., /api/target-endpoint), not the original URL path that the client requested. There is no built-in mechanism in Nuxt/Nitro to make the target endpoint "see" the original URL path as if the client had called it directly. The internal fetch is a new request, and the path is determined by what you specify in the fetch call. If you need the target endpoint to know the original path, you would need to manually forward that information, for example by adding a custom header or including it in the request body. The knowledge sources confirm that event.$fetch forwards the request context and headers, but do not mention any automatic forwarding of the original URL path to the target endpoint. You can see this described in the Forwarding Context & Headers documentation. If you need the target endpoint to be aware of the original path, you must handle this explicitly in your code. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
