Efficient File Transfer Module for NodeJS

Usage no npm install needed!

<script type="module">
  import adobeHttptransfer from 'https://cdn.skypack.dev/@adobe/httptransfer';





The node-httptransfer package is designed to easily and correctly transfer file content from HTTP(S) urls to HTTP(S) urls and between HTTP(S) urls.

The lower-level stream API allows you to transfer content from a URL to any writable stream, and similarly transfer any readable stream to a URL.

The higher-level file API abstracts away the streams and allows you to transfer content to/from files on disk.

The node-httptransfer package requires the async/await features and is built using the node-fetch-npm package.


npm i @adobe/httptransfer

Using streams

Download a stream:

const { downloadStream } = require('@adobe/httptransfer');
async main() {
    const stream = fs.createWriteStream('test.png');
    await downloadStream('http://my.server.com/test.png', stream);

Upload a stream using PUT:

const { uploadStream } = require('@adobe/httptransfer');
async main() {
    const stream = fs.createReadStream('test.png');
    await uploadStream(stream, 'http://my.server.com/test.png');

Using files

Download a file:

const { downloadFile } = require('@adobe/httptransfer');
async main() {
    await downloadFile('http://my.server.com/test.png', 'test.png');

Upload a file using PUT:

const { uploadFile } = require('@adobe/httptransfer');
async main() {
    await uploadFile('test.png', 'http://my.server.com/test.png');

Upload a file to multiple URLs using PUT (used by AEM multi-part upload):

const { uploadAEMMultipartFile } = require('@adobe/httptransfer');
async main() {
    await uploadAEMMultipartFile('test.png', {
        urls: [ "http://my.server.com/test.png.1", "http://my.server.com/test.png.2" ],
        maxPartSize: 1000000

Assuming test.png is 1,800,000 bytes this will upload the first 1,000,000 bytes to http://my.server.com/test.png.1 and the next 800,000 bytes to http://my.server.com/test.png.2.


A CLI tool testbed is provided to try out the node-httptransfer functionality. It supports uploading, downloading, and transferring file content. It also supports Azure Blob stores through Shared Access Signature (SAS) urls created on the fly.

The tool is not intended to be useful on its own, only to test out new features or debug issues.


cd testbed/
npm install

Download an image from a website:

node index.js https://website.com/path/to/image.gif image.gif

Download blob.txt from azure:

node index.js azure://container/path/to/blob.txt blob.txt

Upload blob.txt to azure:

node index.js blob.txt azure://container/path/to/blob.txt

Upload blob.txt in 10,000 byte blocks:

node index.js --max 10000 blob.txt azure://container/path/to/blob.txt

Copy blob.txt within a container:

node index.js azure://container/path/to/blob.txt azure://container/path/to/target.txt
