### Next.js 15 and newer

Latest versions of Next.js allow to run code after the response is sent, with [`after` function](https://nextjs.org/docs/app/api-reference/functions/after).

import { after } from 'next/server'
// ...
export default async function Page() {

// ...
const flags = flagsClient(evaluated.toggles)
const isEnabled = flags.isEnabled("example-flag")

after(async () => {
flags.sendMetrics()
})

return (

)
}
```
