Can't use readableStream's on "data" ?

[akermabon]

hello,

I'm trying to get a file content from ftp, without having to write it on disk.
I'm doing the following, but it seems the "data" event is never triggered...
I'm using latest version (v1.3.5).
Code to reproduce:

const Ftp = require('promise-ftp')
const client = new Ftp();
client.connect()
    .then(() => client.get('path-to-file'))
    .then((stream) => {
        return new Promise( (resolve, reject) => {
            let buffer = '';
            stream.once('close', () => resolve(buffer));
            stream.once('error', reject);
            stream.on('data', function (chunk) {
                console.log(chunk.toString());
                buffer += chunk;
            });
        });
    })
    .then(() => client.end());

Am I missing something ?

I ran in the same problem. The 'data'-Event is never fired, because the stream is never written.
You need to add a Writeable.
Try this:

const Ftp = require('promise-ftp')
const client = new Ftp();
client.connect()
    .then(() => client.get('path-to-file'))
    .then((stream) => {
        return new Promise( (resolve, reject) => {

            stream.pipe(new Writable({
                write(chunk, encoding, callback: (error?) => void) {
                    callback();
                }
            }));

            let buffer = '';
            stream.once('close', () => resolve(buffer));
            stream.once('error', reject);
            stream.on('data', function (chunk) {
                console.log(chunk.toString());
                buffer += chunk;
            });
        });
    })
    .then(() => client.end());
