Is keep-alive the default behavior?

[zhaoyao91]

I thought in server context, keep-alive should be the default option to reuse existing connection. Will I gain this benefit if I use node-fetch?

Not by default, but you can easily create a http agent with keep alive flag enabled to achieve what you want:

@bitinn Will this work?

const res = await fetch(url, {
	headers: {
		'connection': 'keep-alive',
		'content-type': 'application/json'
	}
});

As per the example provided by @bitinn & also my understanding, you need supply this config in http agent used in the request. Only supplying header won't help.
