HTTP keep-alive and TCP connection re-use

[chitholian]

I am using impit-js in NodeJS.

I cannot find any option for connection re-use or keep-alive feature in the documentation.

I think it is a very useful feature (at least for me).

I am waiting for this feature.
If already available, I need the way how to enable it.

Hello and thank you for your interest in this project.

TCP connection reuse is already on by default for separate Impit instances. I.e. in the following snippet:

const impit = new Impit();

const response = await impit.fetch("http://localhost:3000");
console.log(await response.json());
const response2 = await impit.fetch("http://localhost:3000");
console.log(await response2.json());
const response3 = await impit.fetch("http://localhost:3000");
console.log(await response3.json());

setTimeout(async () => {
    const response4 = await impit.fetch("http://localhost:3000");
    console.log(await response4.json());
}, 10e3);

response, response2 and response3 will reuse the same TCP connection. response4 will create a new connection, as the server listening on localhost:3000 closes the connection after 5 seconds.

I added some details regarding this to the documentation via #295.
