Oro Sftp
OSftp Class is a wrapper of ssh2-sftp-client to simplify their use.
ssh2-sftp-client is a SFTP client module for node.js that provides an asynchronous interface for communicating with a SFTP server.
To have the same interface using FTP, you can utilize the OroFtp class available through OroFtp
npm install oro-sftp
Example:
// mjs, ts
import OSFtp from 'oro-sftp';
// cjs
const { OSftp } = require('oro-sftp');
const sftpClient = new OSftp({
host: 'custom-server.com',
port: 22,
user: 'custom-user',
password: 'custom-password',
});
const sftpUpload = await sftpClient.uploadOne(`./folder-from/filename`, 'folder-to/filename');
console.log(sftpUpload);
// -> { status: true, ... }

Error Code List
When an error happens, instead to throw an error, it's returned a managed responseKO.
responseKO is an object with 3 fields:
interface responseKO {
status: false;
error: {
msg: string; // explaining the error
code: OSFtpErrorCode; // string
// ... // other data, it depends on method error
};
tryAgain: boolean;
}
type OSFtpErrorCode =
| 'ECONNREFUSED'
| 'UNCONNECTED'
| 'ENOTFOUND'
| 'ENTIMEOUT'
| 'ENOENT'
| 'EEXIST'
| 'ENOTEMPTY';
new OSftp()
new OSFtp( config?: OSFtpConfig );
type OSFtpConfig = SftpClient.ConnectOptions & {
host?: string;
port?: number;
user?: string;
password?: string;
readyTimeout?: number; // def: 3000
disconnectWhenError?: boolean; // def: true
}
As parameters, you can pass the server config data (or you can also do it in .connect()
).
In addition, config
has param disconnectWhenError
(default true
), so when an error happens, connection closes automatically.
const OSftp = require('oro-sftp');
const config = {
host: 'custom-server.com',
port: 22,
user: 'custom-user',
password: 'custom-password',
readyTimeout: 3000,
disconnectWhenError: true,
};
const sftpClient = new OSftp(config);
.getClient()
sftpClient.getClient(): SftpClient;
If you want to use the library ssh2-sftp-client
, you can get the object.
const sftpClient = new OSftp(config);
const ssh2SftpClient = await sftpClient.getClient();
await .connect()
await sftpClient.connect( config?: OSFtpConfig ) => Promise<OSFtpConnectResponse>;
type OSFtpConfig = PromiseFtp.Options & {
host?: string;
port?: number;
user?: string;
password?: string;
readyTimeout?: number; // def: 3000
disconnectWhenError?: boolean; // def: true
}
export type OSFtpConnectResponse =
| SResponseOKBasic
| SResponseKOObjectAgain<OSFtpConnectError>;
interface SResponseOKBasic {
status: true;
}
interface SResponseKOObjectAgain {
status: false;
error: {
msg: string;
code: OSFtpErrorCode;
config: OSFtpConfig;
}
}
interface OSFtpConnectError {
msg: string;
code: OSFtpErrorCode;
config: OSFtpConfig;
}
When you create a connection, it's expected that you will disconnect it later.
This method return a response, which is an object with status: true | false
.
const sftpClient = new OSftp(config);
const connected = await sftpClient.connect();
console.log(connected);
// -> { status: true }
await .disconnect()
await sftpClient.disconnect() => Promise<OSFtpDisconnectResponse>;
export type OSFtpDisconnectResponse =
| SResponseOKBasic
| SResponseKOBasic;
interface SResponseOKBasic {
status: true;
}
interface SResponseKOBasic {
status: false;
}
Note: If you don't .disconnect()
when finished, the script still running.
Note2: There is a param in config disconnectWhenError
by default true
.
This means that if a method (like upload
or move
) return status: false
, the ftpClient will be disconnected automatically.
This method return a response, which is an object with status: true | false
.
const sftpClient = new OSftp(config);
const connected = await sftpClient.connect();
// ...
const disconnected = await sftpClient.disconnect();
console.log(disconnected);
// -> { status: true }
await .upload()
await sftpClient.upload( filepathFrom: string, filepathTo?: string )
=> Promise<OSFtpFileResponse>;
export type OSFtpFileResponse =
| SResponseOKObject<OSFtpFileObject>
| SResponseKOObject<OSFtpFileError>;
interface SResponseOKObject {
status: true;
filename: string;
filepath: string;
}
interface SResponseKOObject {
status: false;
error: {
msg: string;
filepathFrom: string;
filepathTo?: string;
code?: OSFtpErrorCode;
}
}
interface OSFtpFileObject {
filename: string;
filepath: string;
}
interface OSFtpFileError {
msg: string;
filepathFrom: string;
filepathTo?: string;
code?: OSFtpErrorCode;
}
upload
is the action to copy from local to ftp folder.
If filepathTo
is not declared, it takes the filename of filepathFrom
and save it on ftp main folder.
const sftpClient = new OSftp( config );
const connected = await sftpClient.connect();
if( ! connected.status ) { return connected; }
const uploaded = await sftpClient.upload( './files/custom-file.pdf' );
console.log( uploaded );
// -> { status: true, filename: 'custom-file.pdf', ... }
sftpClient.disconnect();
await .uploadOne()
await sftpClient.upload( filepathFrom: string, filepathTo?: string )
=> Promise<OSFtpUploadOneResponse>;
export type OSFtpUploadOneResponse =
| SResponseOKObject<OSFtpFileObject>
| SResponseKOObject<OSFtpFileError | OSFtpConnectError>;
interface SResponseOKObject {
status: true;
filename: string;
filepath: string;
}
type SResponseKOObject =
| {
status: false;
error: {
msg: string;
filepathFrom: string;
filepathTo?: string;
code?: OSFtpErrorCode;
}
}
| {
status: false;
error: {
msg: string;
code: OSFtpErrorCode;
config: OSFtpConfig;
}
}
interface OSFtpFileObject {
filename: string;
filepath: string;
}
interface OSFtpFileError {

filepathFrom: string;
filepathTo?: string;
code?: OSFtpErrorCode;
}
interface OSFtpConnectError {
msg: string;
code: OSFtpErrorCode;
config: OSFtpConfig;
}
If you want to upload just one file, you can use this method and inside:
- it's connected,
- file is uploaded,
- it's disconnected.
const sftpClient = new OSftp(config);
const uploaded = await sftpClient.uploadOne('./files/custom-file.pdf');
console.log(uploaded);
// -> { status: true, filename: 'custom-file.pdf', ... }
await .download()
await sftpClient.download( filepathFrom: string, filepathTo?: string )
=> Promise<OSFtpFileResponse>;
export type OSFtpFileResponse =

filepath: string;
}
interface SResponseKOObject {
status: false;
error: {
msg: string;

code?: OSFtpErrorCode;
}
}

}
download

is not declared, it takes the filename of filepathFrom
and save it on local main folder.

if( ! connected.status ) { return connected; }
const downloaded = await sftpClient.download( 'custom-file.pdf' );
console.log( downloaded );
// -> { status: true, filename: 'custom-file.pdf', ... }
sftpClient.disconnect();
await .list()
await sftpClient.list( folder?: string, filters?: OSFtpListFilters )
=> Promise<OSFtpListResponse>;
interface OSFtpListFilters {
onlyFiles?: boolean | undefined; // def: false
onlyFolders?: boolean | undefined; // def: false
pattern?: ListFilterFunction | undefined;
}
type ListFilterFunction = (fileInfo: FileInfo) => boolean;
export type OSFtpListResponse =

if( ! connected.status ) { return connected; }
const files = await sftpClient.list();
console.log( files );
// -> { status: true, count: 7, list: [ ... ] }
sftpClient.disconnect();
- Filter:
pattern
pattern
filter can be a regular expression (most powerful option) or
a simple glob-like string where *
will match any number of characters, e.g.
foo* => foo, foobar, foobaz
*bar => bar, foobar, tabbar
*oo* => foo, foobar, look, book
response example
{
status: true,
count: // list.length
list: [
{
type: // file type(-, d, l)
name: // file name
longname: // file name as linux promp
path: // file path
date: // file date of modified time
modifyDate: // file date of modified time
accessDate: // file date of access time

it allows to remove the folder-content too.
When strict = false

const removed = await sftpClient.rmdir( 'custom-folder', true );
console.log( removed );
// -> { status: true, foldername: 'custom-folder', ... }
sftpClient.disconnect();
Testing
If you want to run npm run test
in local, first you need to run a sftp server (i.e. via docker):
# 'atmoz/sftp:alpine' is smaller and faster
> docker run --name oro-sftp-server -p 2222:22 -d atmoz/sftp:alpine -e osftp_user:osftp_pass:::osftp_folder
# change the login-folder to have full privileges in main folder
> docker exec oro-sftp-server sh -c "sed -i -e 's#ForceCommand internal-sftp#ForceCommand internal-sftp -d /osftp_folder#' /etc/ssh/sshd_config"
# restart container
> docker restart oro-sftp-server
Then, you have to declare your own ./test/config.json
,
You can copypaste it from ./test/config-default.json
{
"host": "localhost",
"port": 2222,
"user": "osftp_user",
"password": "osftp_pass"
}
