AWS Transfer for SFTP (Amazon S3)

See more SFTP Examples

Once you've setup your AWS Transfer for SFTP in the AWS Console, interacting with it is no different than any other SSH/SFTP server. AWS will provide a private key in PEM format. It is used for authentication (instead of a password). React Native

import { SFtp, SshKey } from '@chilkat/react-native'

async function chilkatExample() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const sftp = new SFtp();

  // Connect to the AWS SFTP server.
  // Change the domain to your value.
  const domain = 's-123456df999999fab.server.transfer.eu-west-2.amazonaws.com';
  const port = 22;
  try {
    await sftp.connectAsync(domain, port);
  } catch {
    console.log(sftp.lastErrorText);
    return;
  }

  // Load your AWS SFTP private key PEM file..
  const sshKey = new SshKey();
  let keyText: string;
  try {
    keyText = sshKey.loadText('qa_data/pem/s3_sftp_privateKey.pem');
  } catch {
    console.log(sshKey.lastErrorText);
    return;
  }

  try {
    sshKey.fromOpenSshPrivateKey(keyText);
  } catch {
    console.log(sshKey.lastErrorText);
    return;
  }

  // Authenticate with the SSH server using the private key.
  try {
    await sftp.authenticatePkAsync('myUsername', sshKey);
  } catch {
    console.log(sftp.lastErrorText);
    return;
  }

  // After authenticating, the SFTP subsystem must be initialized:
  try {
    await sftp.initializeSftpAsync();
  } catch {
    console.log(sftp.lastErrorText);
    return;
  }

  // Upload from the local file to the SSH server.
  // Important -- the remote filepath is the 1st argument,
  // the local filepath is the 2nd argument;
  const remoteFilePath = 'hamlet.xml';
  const localFilePath = 'c:/temp/hamlet.xml';

  try {
    await sftp.uploadFileByNameAsync(remoteFilePath, localFilePath);
  } catch {
    console.log(sftp.lastErrorText);
    return;
  }

  console.log('Success.');
