Documentation

the connection to server config pls see ssh2 client event.

list of methods: all the methods will return a Promise;

List

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

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]);

FastGet

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]);

Put

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]);

FastPut

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]);

Mkdir

create a new directory.

// recursive default is false, if true, it will create directory recursive
sftp.mkdir(remoteFilePath, recursive);

Rmdir

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

delete file.

sftp.delete(remoteFilePath);

Rename

rename remoteSourcePath to remoteDestPath (removes remoteSourcePath).

sftp.rename(remoteSourcePath, remoteDestPath);

Chmod

modify rights to remoteDestPath file

sftp.chmod(remoteDestPath, mode);

Connect

connection config you will see here

End

close the sftp connection. when you need it, you can call it in then() or catch().

sftp.end();

Event

add client event handle. you can find more here

close

The socket was closed. hadError is set to true if this was due to error.

sftp.on('close', callbackFn)

end

The socket was disconnected.

sftp.on('end', callbackFn)

error

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)
