ssh2-sftp-client
Advanced tools
The ssh2-sftp-client npm package is a promise-based SFTP client for Node.js, built on top of the ssh2 module. It provides a simple and easy-to-use interface for performing various SFTP operations such as uploading, downloading, listing, and deleting files on a remote server.
Connecting to an SFTP server
This feature allows you to establish a connection to an SFTP server using the provided host, port, username, and password.
const Client = require('ssh2-sftp-client');
const sftp = new Client();
sftp.connect({
host: 'example.com',
port: '22',
username: 'username',
password: 'password'
}).then(() => {
console.log('Connected');
}).catch(err => {
console.error(err.message);
});Uploading a file
This feature allows you to upload a file from your local system to the remote SFTP server.
sftp.put('local/path/to/file.txt', 'remote/path/to/file.txt').then(() => {
console.log('File uploaded');
}).catch(err => {
console.error(err.message);
});Downloading a file
This feature allows you to download a file from the remote SFTP server to your local system.
sftp.get('remote/path/to/file.txt', 'local/path/to/file.txt').then(() => {
console.log('File downloaded');
}).catch(err => {
console.error(err.message);
});Listing files in a directory
This feature allows you to list all files and directories in a specified remote directory.
sftp.list('remote/path/to/directory').then(data => {
console.log(data);
}).catch(err => {
console.error(err.message);
});Deleting a file
This feature allows you to delete a specified file from the remote SFTP server.
sftp.delete('remote/path/to/file.txt').then(() => {
console.log('File deleted');
}).catch(err => {
console.error(err.message);
});The ssh2 package is a general-purpose SSH2 client and server module for Node.js. It provides a lower-level API compared to ssh2-sftp-client, allowing for more granular control over SSH and SFTP operations. However, it requires more boilerplate code to accomplish the same tasks.
The node-sftp package is another SFTP client for Node.js. It offers similar functionalities to ssh2-sftp-client but is less popular and has fewer features. It is also not as actively maintained as ssh2-sftp-client.
The scp2 package is a client for SCP (Secure Copy Protocol) in Node.js. While it provides functionalities for transferring files over SSH, it is limited to SCP and does not support the full range of SFTP operations that ssh2-sftp-client does.
a SFTP client for node.js, a wrapper for ssh2
npm install ssh2-sftp-client
let Client = require('ssh2-sftp-client');
let sftp = new Client();
sftp.connect({
host: '127.0.0.1',
port: '8080',
username: 'username',
password: '******'
}).then(() => {
return sftp.list('/pathname');
}).then((data) => {
console.log(data, 'the data info');
}).catch((err) => {
console.log(err, 'catch error');
});
the connection to server config pls see ssh2 client event.
list of methods: all the methods will return a Promise;
Retrieves a directory listing.
sftp.list(remoteFilePath)
directory info:
type: // file type(-, d, l)
name: // file name
size: // file size
modifyTime: // file timestamp of modified time
accessTime: // file timestamp of access time
rights: {
user:
group:
other:
},
owner: // user ID
group: // group ID
Get a Chunk from remotePath. The encoding is passed to Node Stream (https://nodejs.org/api/stream.html) and it controls how the content is encoded. For example, when downloading binary data, 'null' should be passed (check node stream documentation). Default to 'utf8'.
sftp.get(remoteFilePath, [useCompression], [encoding], [addtionalOptions]);
Downloads a file at remotePath to localPath using parallel reads for faster throughput. options properties you can find fastGet method here.
sftp.fastGet(remotePath, localPath, [options]);
upload a file from localPath or Buffer, Stream data to remoteFilePath.The encoding is passed to Node Stream to control how the content is encoded. Default to 'utf8'.
sftp.put(localFilePath, remoteFilePath, [useCompression], [encoding], [addtionalOptions]);
sftp.put(Buffer, remoteFilePath, [useCompression], [encoding], [addtionalOptions]);
sftp.put(Stream, remoteFilePath, [useCompression], [encoding], [addtionalOptions]);
Uploads a file from localPath to remotePath using parallel reads for faster throughput. options properties you can find fastPut method here.
sftp.fastPut(localPath, remotePath, [options]);
create a new directory.
// recursive default is false, if true, it will create directory recursive
sftp.mkdir(remoteFilePath, recursive);
remove the directory or file.
// recursive default is false, if true, it will remove directory recursive even if is not empty
sftp.rmdir(localPath, recursive);
delete file.
sftp.delete(remoteFilePath);
rename remoteSourcePath to remoteDestPath (removes remoteSourcePath).
sftp.rename(remoteSourcePath, remoteDestPath);
modify rights to remoteDestPath file
sftp.chmod(remoteDestPath, mode);
connection config you will see here
close the sftp connection. when you need it, you can call it in then() or catch().
sftp.end();
add client event handle. you can find more here
The socket was closed. hadError is set to true if this was due to error.
sftp.on('close', callbackFn)
The socket was disconnected.
sftp.on('end', callbackFn)
An error occurred. A 'level' property indicates 'client-socket' for socket-level errors and 'client-ssh' for SSH disconnection messages. In the case of 'client-ssh' messages, there may be a 'description' property that provides more detail.
sftp.on('error', callbackFn)
Requires node.js v7.5.0 or above.
