Disabling HTTP Keep-Alive

Next.js automatically polyfills node-fetch and enables HTTP Keep-Alive by default. You may want to disable HTTP Keep-Alive for certain fetch() calls or globally.

For a single fetch() call, you can add the agent option:

  1. import { Agent } from 'https'
  3. const url = 'https://example.com'
  4. const agent = new Agent({ keepAlive: false })
  5. fetch(url, { agent })

To override all fetch() calls globally, you can use next.config.js:

  1. module.exports = {
  2.   httpAgentOptions: {
  3.     keepAlive: false,
  4.   },
  5. }
