Stream and pipe resources with responseType: 'stream'

[LAU TIAM KOK]

Describe the feature

With axios, we can stream and pipe resources like this:

import axios from 'axios'
import fs from 'fs'

const file = fs.createWriteStream('./assets/sample.jpg')

const { data } = await axios({
  url: 'https://samplesite.com/uploads/sample.jpg',
  method: 'GET',
  responseType: 'stream'
})
data.pipe(file)

How can we do it with ofetch? Any documentation around?

Hi. You can use same responseType: "stream" API with ofetch 👍🏼

I am getting TypeError: response.pipe is not a function, my code:

import { ofetch } from 'ofetch';
import fs from 'fs';

const response = await ofetch('https://defly.io/img/add-skins.js', {
    responseType: "stream",
});

response.pipe(fs.createWriteStream('./cache/allSkins.json'));

unlike node-fetch, ofetch returns a web ReadableStream which has .pipeTo method and accepts also a web WritableStream.

This is a working example for Node.js 18+

import { ofetch } from "ofetch";
import fs from "node:fs";

const response = await ofetch("https://defly.io/img/add-skins.js", {
  responseType: "stream",
});

const fsStream = fs.createWriteStream("./add-skins.js");

response.pipeTo(
  new WritableStream({
    write(chunk) {
      fsStream.write(chunk);
    },
    close() {
      fsStream.close();
    },
  })
);
