Usage

Basic configuration

Configure module, configuration object will be check by an Joi schema

var logger    = require('yocto-logger');
var sftp      = require('yocto-sftp')(logger);

var config = {
  host        : "10.10.10.10",
  port        : 22,
  user        : "test",
  password    : "pwd",
  algorithms  : {
    serverHostKey: [ 'ssh-rsa', 'ssh-dss' ],
  },
  agent       : process.env.SSH_AUTH_SOCK
};


// path dir to list
var pathDir = '/jumbodrive.re/ads/';

// connect
sftp.load(config).then(function () {
  console.log('\n --> config success ... ');
  // connect to client
  sftp.connect().then(function(client) {
    // the client is :
    // {  
    //    // ssh2 instance
    //    client : client,
    //    // sftp instance
    //    sftp   : sftp
    // }
    console.log('\n --> connect success ');

    setTimeout(function () {
      console.log('\n --> end client connection ...');
      // manually close the connect
      sftp.end(client);
    }, 2000);
  }).catch(function (error) {
    console.log('\n --> connect failed ', error);
  });
}).catch(function (error) {
  console.log('\n --> error : ', error);
});

Get an document

This method download an file from sftp server

var localPathFile   = '/toto';
var remotePathFile  =  '/tata';

// connect
sftp.load(config).then(function () {
  console.log('\n --> config success ... ');

  sftp.get(localPathFile, remotePathFile).then(function (list) {
    console.log('\n --> ls success \n', list);

  }).catch(function (error) {
    console.log('\n --> ls failed ', error);
  });
}).catch(function (error) {
  console.log('\n --> error : ', error);
});

List directory

This method return an array of files description from ftp server

var remotePathFOlder  =  '/tata/';

// connect
sftp.load(config).then(function () {
  console.log('\n --> config success ... ');

  sftp.ls(remotePathFOlder).then(function (list) {
    console.log('\n --> ls success \n', list);

  }).catch(function (error) {
    console.log('\n --> ls failed ', error);
  });
}).catch(function (error) {
  console.log('\n --> error : ', error);
});

Delete an document

This method remove an file in sftp server

var remotePathFile  =  '/tata.png';

// connect
sftp.load(config).then(function () {
  console.log('\n --> config success ... ');

  sftp.delete(remotePathFile).then(function (list) {
    console.log('\n --> ls success \n', list);

  }).catch(function (error) {
    console.log('\n --> ls failed ', error);
  });
}).catch(function (error) {
  console.log('\n --> error : ', error);
});

Put an document

This method upload an file in sftp server

var localPathFile   = '/toto';
var remotePathFile  =  '/tata';

// connect
sftp.load(config).then(function () {
  console.log('\n --> config success ... ');

  sftp.put(localPathFile, remotePathFile).then(function (list) {
    console.log('\n --> ls success \n', list);

  }).catch(function (error) {
    console.log('\n --> ls failed ', error);
  });
}).catch(function (error) {
  console.log('\n --> error : ', error);
});

Check if an file exit on ftp server

This Check if an file exit on ftp server

var remotePathFile  =  '/tata';

// connect
sftp.load(config).then(function () {
  console.log('\n --> config success ... ');

  sftp.fileExist(remotePathFile).then(function (list) {
    console.log('\n --> ls success \n', list);

  }).catch(function (error) {
    console.log('\n --> ls failed ', error);
  });
}).catch(function (error) {
