 <details id="after-serverless">
   <summary>Reference: supporting `after` for serverless platforms</summary>
   Using `after` in a serverless context requires waiting for asynchronous tasks to finish after the response has been sent. In Next.js and Vercel, this is achieved using a primitive called `waitUntil(promise)`, which extends the lifetime of a serverless invocation until all promises passed to [`waitUntil`](https://vercel.com/docs/functions/functions-api-reference#waituntil) have settled.
-  
-  If you want your users to be able to run `after`, you will have to provide your implementation of `waitUntil` that behaves in an analogous way.
-  
-  When `after` is called, Next.js will access `waitUntil` like this:
-  
-  ```jsx
-  const RequestContext = globalThis[Symbol.for('@next/request-context')]
-  const contextValue = RequestContext?.get()
-  const waitUntil = context?.waitUntil
-  ```
-  
-  Which means that `globalThis[Symbol.for('@next/request-context')]` is expected to contain an object like this:
-  
-  ```tsx
-  type NextRequestContext = {
-    get(): NextRequestContextValue | undefined
-  }
-  
-  type NextRequestContextValue = {
-    waitUntil?: (promise: Promise<any>) => void
-  }
-  ```
-  
-  Here is an example of the implementation.
-  
-  ```tsx
-  import { AsyncLocalStorage } from 'node:async_hooks'
-  
-  const RequestContextStorage = new AsyncLocalStorage<NextRequestContextValue>()
-  
-  // Define and inject the accessor that next.js will use
-  const RequestContext: NextRequestContext = {
-    get() {
-      return RequestContextStorage.getStore()
-    },
-  }
-  globalThis[Symbol.for('@next/request-context')] = RequestContext
-  
-  const handler = (req, res) => {
-    const contextValue = { waitUntil: YOUR_WAITUNTIL }
-    // Provide the value
-    return RequestContextStorage.run(contextValue, () => nextJsHandler(req, res))
-  }
-  ```
