How can I increase the headersTimeout with Node.js's fetch?

[ImRodry]

I saw a PR that got merged recently into the latest 18.x release that supposedly increased the headers and body timeouts to 300s to match Chrome, however I'm still getting timed out in 30s. Is there a way to force the timeout to be whatever value I want?

What Node version are you using?

[ImRodry]

Yes

Can you provide a
Minimum Reproducible Example?

[ImRodry]

Not really, it’s literally just any fetch call. Regardless I only want to know how to change that setting

Sadly we cannot help you that much without a
Minimum Reproducible Example.

On a big overview, you cannot do that with fetch, as the spec does not support that configuration. One thing you can do, if wanting to use fetch in Node, is to pass a custom dispatcher that has all the timeout settings configured already.

e.g.

import { fetch, Agent } from 'undici'

const res = await fetch('https://example.com', {
  // Mocks are also supported
  dispatcher: new Agent({
    keepAliveTimeout: 10,
    keepAliveMaxTimeout: 10
  })
})
const json = await res.json()
console.log(json)

Thanks, that’s all I wanted
