Qusly-Core

Qusly-Core is a powerful multi-protocol library for file transfer. Created for Qusly.

Features

• Supports FTP, FTPS, SFTP
• API that allows to call methods asynchronously
• Informative transfer progress info - e.g. eta, speed in B/s
• Connection pool
• Ability to register custom protocols

Example

import { Client } from 'qusly-core';

async function main() {
  const client = new Client({ pool: 2 });

  await client.connect({
    protocol: 'ftp',
    host: 'www.example.com',
    user: 'root',
    password: 'password',
  });

  // It will handle all methods at once.
  const [documents, videos] = await Promise.all([
    client.list('/documents'),
    client.list('/videos'),
  ]);

  console.log(document, videos);

  await client.disconnect();
}

main();

Installation

$ npm install qusly-core

Components

We use ssh2 and basic-ftp under the hood.

Task queue

Certain protocols such as ftp don't support handling many request at the same time. When app calls API many times from many places, handling manually these cases is very hard - you can't use await in the most cases.

What if you want to use many connections to speed up transfering files?

That's where we come in. This library supports it all thanks to the powerful task manager.

Connection pool

Allows you to:

• Use all connections for every method
• Use one connection to generic methods e.g. listing files and the rest for transfering files
