Typescript integration

[jeffrson]

Hi,
would love to see typescript support like
import { SFTP } from 'ssh2-promise'

Currently there seems to be no way to access the type of SFTP (in class or interface) at all.

[sanketbajoria]

Currently it is exposed as below
var SFTP = require('ssh2-promise').SFTP

[jeffrson]

Then it's just "any".

Workaround:

import Ssh from "ssh2-promise";
const dummy = () => new Ssh({}).sftp();
type SFTP = ReturnType<typeof dummy>;

[sanketbajoria]

Now we support SFTP type

//without esModuleInterop
import SFTP = require('ssh2-promise/lib/sftp')

//with esModuleInterop
import SFTP from 'ssh2-promise/lib/sftp'
