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:

import { Agent } from 'https'

const url = 'https://example.com'
const agent = new Agent({ keepAlive: false })
fetch(url, { agent })

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

module.exports = {
  httpAgentOptions: {
    keepAlive: false,
  },
}
